Intended Use

The SpideRX Embolic Protection Device is indicated for use as a guidewire and embolic protection system to contain and remove embolic material (thrombus/debris) while performing angioplasty and stenting procedures in carotid arteries. The diameter of the artery at the site of filter basket placement should be between 3.0mm and 7.0mm.

Device Story

SpideRX is a percutaneously delivered distal embolic protection system; utilizes nitinol mesh filter mounted on a convertible 190/320 cm PTFE-coated 0.014" stainless steel capture wire. Operated by interventionalists in clinical settings during carotid revascularization. Delivery involves tracking dual-ended catheter over primary guidewire distal to lesion; primary wire removed; capture wire advanced; filter deployed by withdrawing catheter. Filter apposes vessel wall to strain debris while maintaining distal blood flow. Capture wire serves as guidewire for angioplasty/stenting. Post-intervention, recovery catheter advanced over capture wire to collapse filter and trap debris for removal. Benefits patient by reducing risk of distal embolization during carotid stenting.

Clinical Evidence

Clinical evidence provided via the CREATE (Carotid Revascularization with ev3 Arterial Technology Evolution) Trial, a non-randomized multi-center registry study. Evaluated safety and performance of SpideRX used with ACCULINK Carotid Stent System. Primary endpoint event rates showed no statistically significant differences compared to historical/predicate performance, supporting safety and efficacy. Non-clinical evidence included biocompatibility, sterilization, packaging, shelf-life, and functional performance testing.

Technological Characteristics

Rapid-exchange distal embolic protection system. Components: nitinol mesh filter, PTFE-coated 0.014" stainless steel capture wire, dual-ended delivery/recovery catheter. Compatible with 0.014"/0.018" guidewires. Features radiopaque guidewire tips and filter markers. Mechanical deployment/retrieval mechanism. No software or electronic components.

Indications for Use

Indicated for patients undergoing carotid artery angioplasty and stenting procedures requiring embolic protection; suitable for vessel diameters between 3.0mm and 7.0mm.

RX ACCUNET™ Embolic Protection System (K042218) FilterWire EZTM Embolic Protection System (K032884)

#### Device Description:

The SpideRX Embolic Protection Device is a percutaneously delivered distal embolic protection system that can be delivered over any 0.014" or 0.018" guidewire. The SpideRX Embolic Protection Device contains a Capture Wire composed of a nitinol mesh filter mounted on a convertible 190/320 cm PTFEcoated 0.014" stainless steel wire, and a dual-ended SpideRX Catheter for delivery and recovery.

{1}------------------------------------------------

#### Intended Use:

The SpideRX Embolic Protection Device is indicated for use as a guidewire and embolic protection system to contain and remove embolic material (thrombus/debris) while performing angioplasty and stenting procedures in (inrotious areries. The diameter of the artery at the site of filter basket placement should be between 3.0mm and 7.0mm.

## Summary of Technological Characteristics:

The SpideRX Embolic Protection Device is a rapid exchange distal embolic r no Spideret Line on is compatible with 0.014"/0.018" primary guidewires and utilizes a nitinol mesh filter to capture debris.

The delivery end of the SpideRX dual-ended Catheter is placed distal to the lesion by tracking over the primary guidewire. The primary guidewire is then removed and the SpideRX Capture Wire is advanced through the delivery end of the SpideRX Catheter. Filter deployment is accomplished by holding the SpideRX Capture Wire steady while pulling back and removing the SpideRX Catheter. When deployed, the nitinol mesh filter opens, apposes the vessel wall, and then acts as a strainer by capturing debris while allowing uninterrupted blood flow distally. The Capture Wire then functions as the guidewire while percutaneous transluminal angioplasty or stenting procedures are performed. Upon completion of the intervention, the recovery end of the SpideRX Catheter is advanced over the Capture Wire and the filter is recovered into the SpideRX Catheter, closing the filter and trapping the embolic debris inside the filter. The system is then removed.

The SpideRX Embolic Protection Device is substantially equivalent to the Guidant® RX ACCUNET™ Embolic Protection System (K042218) and the Boston Scientific FilterWire EZ Embolic Protection System (K032884) in regards to device design, principals of operation and materials. The SpideRX Embolic Protection Device is also substantially equivalent to the RX ACCUNET in intended use. The following features are the same or similar between the SpideRX Device and the predicate devices:

- Distal filter embolic protection .
- Ranid-exchange devices .
- Filter/basket component .
- Compatible with 0.014" interventional devices .
- Capture Wire accommodates both rapid exchange and over-the-wire PTA . devices (FilterWire EZ and RX ACCUNET are available in both 190 and 300cm lengths, while SpideRX Device wire is 320cm in length, and snaps to 190cm to accommodate rapid exchange devices)
- Intended for use in similar vessel sizes .
- Radionaque guidewire tips and filter markers .
- Radiopaque markers on sheath/catheter tips .

Comparisons of the SpideRX Device to the predicate devices show that technological characteristics such as materials, biocompatibility, performance technological onaracteries ackaging are substantially equivalent to the currently marketed RX ACCUNET and FilterWire EZ devices.

### Summary of Testing:

Non-Clinical: In vitro testing of the SpideRX Embolic Protection Device consisted of biocompatibility, sterilization, packaging, product shelf life and consisted of crossing Functional performance testing was also completed in portormalies testings verified that the SpideRX Device is adequate for its intended use. Additionally, the test results demonstrated that the SpideRX Device is equivalent to its predicate devices.

Clinical: The SpideRX Arm of the Carotid Revascularization with ev3 Arterial Technology Evolution (CREATE) Trial was a non-randomized multi-center registry study that was performed to assess the safety and performance of the SpideRX Device when used with the commercially available ACCULINK™ Carotid Stent System. The differences observed between the primary endpoint event rates were not statistically significant, which demonstrate the safety and performance of the SpideRX Device for its intended use.

#### Statement of Equivalence:

The SpideRX Embolic Protection Device is substantially equivalent to the currently marketed RX ACCUNET™ Embolic Protection System (K042218) in intended use, materials, technological characteristics and performance. The SpideRX Embolic Protection Device is substantially equivalent to the FilterWire EZTM Embolic Protection System (K032884) in materials, technological characteristics and performance.
