Device Story
AltiVate Anatomic Shoulder System is a modular shoulder joint prosthesis for total shoulder arthroplasty or hemiarthroplasty. Components include humeral stem, neck, head, and glenoid. Humeral stem features rectangular proximal cross-section, distal cylindrical geometry, and anterior/posterior fins with suture holes for soft tissue reattachment. Humeral neck uses male Morse tapers to interface with stem and head; offset head configurations allow intraoperative anatomical adjustment. Glenoid component, made of vitamin E UHMWPE, features spherical back surface with four pegs; central peg has annular barbs, peripheral pegs have Tri-lobe fixation features. Device is implanted by orthopedic surgeons in clinical/hospital settings to replace damaged joint surfaces, restore function, and alleviate pain. System provides rotational stability and allows superior/inferior and anterior/posterior translation.
Clinical Evidence
No clinical data. Substantial equivalence supported by non-clinical mechanical testing, including Rocking Horse, Stem/Head Fatigue, and Humeral Head Disassociation testing, and bacterial endotoxin assessment.
Technological Characteristics
Components: Humeral stem, neck, head, and glenoid. Materials: Metal and vitamin E ultra-high molecular weight polyethylene (UHMWPE). Fixation: Cemented (all components) or uncemented (porous coated humeral stems). Design: Modular with Morse taper interfaces; glenoid features Tri-lobe peripheral pegs and barbed central peg. Sterilization: Not specified.
Indications for Use
Indicated for patients with shoulder pain and dysfunction due to degenerative joint disease (osteoarthritis, avascular necrosis, post-traumatic arthritis), rheumatoid/inflammatory arthritis, functional deformity (fracture malunion), humeral head fracture, or revision of prior devices with sufficient bone stock. Hemiarthroplasty indication requires functional deltoid muscle and includes rotator cuff tear arthropathy.
Regulatory Classification
Identification
A shoulder joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a shoulder joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a humeral resurfacing component made of alloys, such as cobalt-chromium-molybdenum, and a glenoid resurfacing component made of ultra-high molecular weight polyethylene, and is limited to those prostheses intended for use with bone cement (§ 888.3027).

## Description:
The AltiVate Anatomic™ Shoulder System consists of four primary components: humeral stem, neck, head and glenoid. Components are offered for use for either primary or revision surgery applications, in a hemi or total shoulder application.
The proximal body of the stem is rectangular in cross-sectional geometry and tapers proximal to distal. The distal stem is cylindrical. Anterior and posterior fins are located on the proximal body to help provide rotational stability. The anterior and posterior fins have suture holes to allow reattachment of soft tissue and bone fragments in the case of humeral head fracture.
The humeral neck has two male Morse type tapers that differ in size to prevent incorrect installation. The smaller Morse type taper interfaces with the female Morse type taper in the humeral stem, while the larger Morse type taper interfaces with the female Morse type taper in the humeral head.
The humeral heads are available in standard and offset configurations. In the offset configuration, the male Morse type taper on the humeral heads is offset from the center that makes it possible to orient the head in asymmetric positions on the symmetric stem, thus allowing the surgeon to intraoperatively select the position of the humeral head to recreate the anatomy of the individual patient.
The glenoid components are fabricated from vitamin E ultra-high molecular weight polyethylene and ultra-high molecular weight polyethylene. The articulating surface has a radius of curvature greater than the corresponding humeral head. This allows translation in the superior/inferior and anterior/posterior directions. The back surface of the component is spherical in geometry and has four pegs for fixation in the glenoid. The central peg has three annular barbs and the peripheral pegs have machined fixation features, referred to as Tri-lobes, to provide immediate fixation to the patient's glenoid when inserted.

Two short videos show you everything — or skip straight to the written tutorial if you'd rather read. You can reopen this any time from the Tutorial button in the top bar.
Part 1 — Search, results, and everyday workflows 16 min
Part 2 — Embeddings: the galaxy map 3 min
1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
Try it yourself
Head to the search page and work through a few of these AI/ML fuzzy searches to build intuition: perivascular fat on CT · aortic valve calcification opportunistic screening on noncontrast CT · breast cancer prediction on digital pathology slides · autism detection · gestational age prediction · a hearing aid that can also detect a pulse · foundation model based analysis of ECG · large language models · penetration test. Watch how the relevance scores, intended use, and AI Performance tables tell you when results stop being meaningful.
