Intended Use
angioLOCK® Non-Absorbable Polymer Ligation Clips are intended for use in procedures involving ligation of vessels or tissue structures. Surgeons should apply the appropriate size of the vessel or tissue structure to be ligated such that the clip completely encompasses the vessel or tissue structure.
Device Story
angioLOCK clips are permanent, non-absorbable, sterile, single-use surgical implants; used for vessel or tissue ligation. Clips are made of acetal homopolymer; supplied in color-coded cartridges. Surgeons use compatible manual appliers (open or laparoscopic) to load, position, and close clips. Mechanism involves haptic feedback when clip bosses seat in applier grooves; closing action pivots upper and lower curved legs with inner teeth via a hinged section to latch securely around tissue. Output is a mechanical ligation of the target structure. Device provides secure vessel occlusion; benefits include reliable hemostasis during surgery. Used in clinical settings by surgeons.
Clinical Evidence
Bench testing only. No clinical data. Performance established via dimensional analysis, biocompatibility testing, and qualitative closure testing comparing angioLOCK to the predicate Hem-o-lok. Testing confirmed identical geometry, material safety, and mechanical function (latching, applier compatibility, and release).
Technological Characteristics
Material: Tenac 5010 (polyacetal polymer). Form factor: Hinged clip with inner teeth, available in M/L, LG, and XLG sizes. Mechanism: Mechanical latching via applier. Sterilization: Ethylene Oxide (EO). Connectivity: None (mechanical).
Indications for Use
Indicated for ligation of vessels or tissue structures in surgical procedures. Contraindicated for use as a fallopian contraceptive tubal occlusion device and for ligating the renal artery during laparoscopic donor nephrectomies.
Regulatory Classification
Identification
An implantable clip is a clip-like device intended to connect internal tissues to aid healing. It is not absorbable.

#### D. Clip Device Description
AngioLOCK ligating clips are permanent implant, non-absorbable, sterile single use, surgical clips made of implantable grade polymer and are available in multiple sizes.
ligating clips are non-absorbable, non-active implantable devices to be used for ligation of vessels and tissue structures. The clips are made of acetal homopolymer and are offered in three sizes; medium/large, large and x-large. Each clip size is compatible with a corresponding clip applier that may be designed for either general or endoscopic procedures. The clips are supplied in quantities of six according to size in color coded cartridges that are prepackaged sterile and single-use.
angioLOCK® open and Laparoscopic Ligation Clip Appliers are for use as delivery devices for angioLOCK® Non-Absorbable Polymer Ligation Clips. Other ligation clips cannot be used with these appliers. angioLOCK® Laparoscopic Polymer Ligation Clip Appliers are designed for use with specific size cannulas.
- نن Indications For Use: angioLOCK® Non-Absorbable Polymer Ligation Clips are intended for use in procedures involving ligation of vessels or tissue structures. Surgeons should apply the size clip for the size of the vessel or tissue structure to be ligated such that the clip completely encompasses the vessel or tissue structure.
{4}------------------------------------------------
- Contraindications: angioLOCK® Non-Absorbable Polymer Ligation Clips are not intended for use as a ட் fallopian contraceptive tubal occlusion device. angioLOCK® Non-Absorbable Polymer Ligation Clips are contraindicated for use in ligating the renal artery during laparoscopic donor nephrectomies.
## G. Characteristic Comparison to Predicate Device Equivalence
The A2 Medical Systems polymer ligating clips are substantially equivalent to the predicate device Hem-o-lok in design and use.
- a. Substantially Equivalent areas are:
- i. Both are single use devices
- ii. Both will latch close over vessels
- iii. Both use the same clip Tenac 5010 material: nonabsorbable polyacetal polymer
- iv. Both have the same clinical application for indications and contraindications
- Both have the same mechanism of action cartridge and clip design allow for an applier to V. easily load a clip, haptic feedback occurs when the clip bosses locate in the applier grooves, and clips are then removed for use. When the clip is closing the upper and lower curved legs with inner teeth pivots in from a hinged section and haptic feedback occurs as clips are latched closed.
- vi. Of the four sizes provided M, M/L, LG, and XLG; they have the same geometry and beam leg height and leg thickness and round boss diameters
- vii. Both have cartridges that are color coded to match applier ring colors
- Both use traditional EO sterilization processing viiii.
- İX. Both use peel open blister packs with 6 clips each.
- X. Both use injection molding to form the clips
- b. Differences:
- i. A2 Medical Systems polymer clips are made in the USA and Hem-o-lok is made in Mexico.
#### H. Summary of Performance Data
AngioLOCK ligating clips are made of an implantable grade of polyacetal polymer with same dimensions and same material characteristics as the predicate Teleflex Medical Hem-o-lok ligating clips.
- a. Substantial Equivalence analyses preformed:
- i. A2 Medical Systems angioLOCK clip to predicate clip dimensional comparison was completed at an open and closed state within an applier that resulted in having the same function as Hem-o-lok when clips are applied and closed.
- ii. Both biocompatibility and polymer material comparisons prove that the molded and sterilized material used for the angioLOCK clip is as safe and the same as the material used in Hem-o-lok.
- iii. Qualitative - angioLOCK clip closure testing proved that the clips latch/lock, are secure in the applier, and release from applier's jaws equivalent to Hem-o-lok.
- iv. Qualitative - dimensional/geometry comparisons using precise overlays prove that angioLOCK and Hem-o-lok clips are the same size.
- Mechanism of action is the same between angioLOCK and Hem-o-lok; cartridge and clip V. design allows for an applier to easily load a clip, haptic feedback occurs when the clip bosses locate in the applier grooves, and clips are then removed for use. When the clip is closing the upper and lower curved legs with inner teeth pivots in from a hinged section and haptic feedback occurs as clips are latched closed.
#### l. Statement of Substantial Equivalence
The angioLOCK® Ligating Clips are substantially equivalent to their predicate device; the Teleflex Medical Hem-o-lok® Ligating Clips, based upon similarities in intended use, design, principles of operation and performance specifications.
