Intended Use

The Route 92 Medical 070 Access System is indicated for use with compatible guide catheters in facilitating the insertion and guidance of microcatheters into a selected blood vessel in the neurovascular system.

Device Story

System comprises Support Catheter and Delivery Catheter; used by physicians trained in neurovascular interventional techniques. Support Catheter features single-lumen, variable stiffness distal section and stainless-steel proximal control wire. Delivery Catheter is hubbed, single-lumen, variable stiffness. Both are hydrophilically coated. Device facilitates microcatheter navigation through neurovasculature. Used in clinical settings; provided sterile for single use. Output is physical guidance of microcatheters; assists physician in reaching target neurovascular sites. Benefits include improved access to neurovascular anatomy for interventional procedures.

Clinical Evidence

Bench testing only. No clinical data. Performance verified via dimensional analysis, tensile strength, kink/torsion resistance, tip flexibility, air/liquid leakage, burst testing, hydrophilic coating integrity, and particulate recovery (USP <788>). Simulated use testing in neurovascular models confirmed deliverability and compatibility.

Technological Characteristics

Materials: polymers and metals (biocompatible per ISO 10993-1). Design: variable stiffness, coil-reinforced, single-lumen catheters with proximal stainless-steel control wire. Hydrophilic coating. Sterilization: 100% ethylene oxide. Dimensions: Support Catheter (0.070" ID), Delivery Catheter (0.019" ID). Connectivity: None (mechanical device).
