Indications for Use
The Arc™ Intracranial Support Catheter and Arc™ Mini Intracranial Support Catheter are indicated for the introduction of interventional devices into the peripheral and neurovasculature.
Device Story
The Arc and Arc Mini are single-lumen, flexible, variable-stiffness composite catheters featuring a Nitinol structure and a radiopaque distal marker band for fluoroscopic visualization. The distal sections include a hydrophilic coating to reduce frictional force during intravascular navigation. Used by physicians in clinical settings, the catheters are navigated through the vasculature to facilitate the delivery of interventional devices. The device is supplied sterile for single-use. By providing a stable conduit, the catheter assists in reaching target sites within the neurovasculature, potentially improving procedural outcomes for patients undergoing interventional neurovascular procedures.
Clinical Evidence
No clinical studies were performed. Substantial equivalence was established through extensive non-clinical bench testing and design validation. Bench testing included lumen patency, dimensional inspection, distal tip buckling, injection/suction flow rates, vacuum resistance, tensile strength, coating integrity/lubricity, kink resistance, leakage, burst pressure, and torque-to-failure. Biocompatibility was confirmed per ISO 10993-1, including cytotoxicity, sensitization, irritation, systemic toxicity, pyrogenicity, hemolysis, and mutagenicity. Physician usability testing in a tortuous benchtop model confirmed compatibility and performance.
Technological Characteristics
Single-lumen, variable-stiffness composite catheter; Nitinol support structure; PTFE-lined polymer shaft; hydrophilic coating; platinum radiopaque marker band. Dimensions vary by model. Sterilized via ethylene oxide per ISO 11135-1:2007. Biocompatibility per ISO 10993-1. Standalone device.
Indications for Use
Indicated for the introduction of interventional devices into the peripheral and neurovasculature for patients requiring such procedures.
