Intended Use

Removal of thromboemboli from the peripheral vasculature

Device Story

Mechanical thrombectomy catheter; used for non-surgical removal of thrombi/emboli from peripheral vasculature. Device consists of inner/outer shafts, heat-set nitinol braided basket, and proximal actuation handle. Delivered via 8F or larger sheath under fluoroscopic guidance using standard guidewire. Operator (physician) advances catheter to target; expands nitinol basket via handle slider to match vessel diameter (1:1 ratio); retracts catheter to pull clot toward sheath. Clot removed via aspiration or other standard methods. Benefits patient by enabling minimally invasive thrombus removal. Used in clinical/endovascular settings.

Clinical Evidence

No clinical data. Substantial equivalence supported by bench-top performance evaluations including visual inspection, dimensional requirements, mechanical integrity, fluid leakage, kink resistance, torsion, and guidewire/sheath compatibility. Packaging validated per ISO 11607-1 and ISO 11607-2.

Technological Characteristics

Mechanical thrombectomy catheter; materials include heat-set nitinol braid. Features radiopaque marker band for fluoroscopic visualization. Dimensions: 145 cm effective length; 20 mm or 32 mm expanded basket diameter. Compatible with 0.035 in guidewires and ≥8F sheaths. Sterile, single-use. No software or electronic components.

Indications for Use

Indicated for the non-surgical removal of thrombi and emboli from the peripheral vasculature.

Regulatory Classification

Identification

An embolectomy catheter is a balloon-tipped catheter that is used to remove thromboemboli, i.e., blood clots which have migrated in blood vessels from one site in the vascular tree to another.

The device consists of an inner catheter shaft, outer catheter shaft, heat set nitinol braid, and an actuation handle attached to the proximal ends of the shafts. There are two device configurations that differ only in length of the expandable nitinol braided basket. The two configurations are identified by the maximum diameter of the expanded basket (20 mm, 32 mm). The SmartClaw™ Thrombectomy Catheter is introduced through a commercially available sheath sized 8F or larger and delivered to the targeted vessel location under fluoroscopy and standard endovascular techniques using a commercially available guidewire. After it is delivered to the targeted vessel location, the catheter's distal nitinol basket is expanded by moving the handle slider proximally. Fluoroscopic guidance is used to ensure the expanded basket achieves a 1:1 ratio with the vessel diameter. Subsequently, the SmartClaw™ Thrombectomy Catheter is retracted proximally to pull loosened clot towards the sheath. Then, the clot is removed from the patient via aspiration or another commercially available clot removal method as appropriate for procedure requirements. After the clot is removed, the catheter's distal nitinol basket is collapsed, and the SmartClaw™ Thrombectomy Catheter is withdrawn from the targeted vessel location through the sheath. | | Intended Use of Device | Removal of thromboemboli from the peripheral vasculature | | Indications for Use | The SmartClaw™ Thrombectomy Catheter is indicated for the non- surgical removal of thrombi and emboli from the peripheral vasculature. | | Device Technology Characteristics and Comparison to Predicate Device | The SmartClaw™ Thrombectomy Catheter incorporates substantially equivalent design, packaging, fundamental technology, and intended use as those featured in the predicate, the WOLF Thrombectomy™ SmartClaw Catheter (K221391).
