Not intended for use in the coronary vasculature. ## Device Story Nautica™ Micro Catheter is an end-hole, single-lumen catheter designed for navigation through peripheral and neuro vasculature. Device features semi-rigid proximal shaft transitioning to flexible distal shaft; dual radiopaque markers for fluoroscopic visualization; lubricious outer coating. Operated by physicians under fluoroscopic guidance. Introduced over steerable guidewire to target site. Enables controlled selective infusion of therapeutic agents or contrast media. Benefits include precise delivery of embolics or diagnostics to specific vascular locations. ## Clinical Evidence Bench testing only. In-vitro performance testing included dimensional inspection, tensile strength, burst pressure, flow rate, torque, and simulated use. Biocompatibility verified per ISO 10993-1 for external communicating, blood contact, limited exposure (<24 hrs) device. ## Technological Characteristics End-hole, single-lumen catheter. Semi-rigid proximal shaft, flexible distal shaft. Dual radiopaque markers. Lubricious outer coating. Biocompatibility per ISO 10993-1. Mechanical device; no energy source or software. ## Regulatory Identification A continuous flush catheter is an attachment to a catheter-transducer system that permits continuous intravascular flushing at a slow infusion rate for the purpose of eliminating clotting, back-leakage, and waveform damping. ## Predicate Devices - MTI Titan™ Micro Catheter ([K022003](/device/K022003.md)) - MTI Rebar® Micro Catheter ([K993672](/device/K993672.md)) ## Related Devices - [K093750](/device/K093750.md) — ECHELON MICRO CATHETER, MARATHON MICRO CATHETER, NAUTICA MICRO CATHETER ULTRAFLOW HPC FLOW DIRECTED MICRO CATHETER, REBA · Ev3, Inc. · Dec 9, 2009 - [K030688](/device/K030688.md) — ECHELON MICRO CATHETER, MODEL 105-5092-150 · Micro Therapeutics, Inc. · Mar 28, 2003 - [K042187](/device/K042187.md) — ECHELON 10,45 TIP SHAPE MICRO CATHETER ECHELON 10,90 TIP SHAPE MICRO CATHETER, ECHELON 14,45 TIP SHAPE MICRO CATHETER,90 · Micro Therapeutics, Inc. · Sep 2, 2004 - [K031992](/device/K031992.md) — ECHELON MICRO CATHETER, MODEL 105-5091 · Micro Therapeutics, Inc. · Aug 7, 2003 - [K051990](/device/K051990.md) — ECHELON MICRO CATHETER · Micro Therapeutics, Inc. · Jan 4, 2006 ## Submission Summary (Full Text) {0}------------------------------------------------ MTI Confidential MAR 0 7 2003 ## 510(k) Summary 4. Micro Therapeutics, Inc. Nautica™ Micro Catheter December 12, 2002 Special 510(k) (modifications to K022003) Prepared December 13, 2002 Nautica™ Micro Catheter TRADE NAME Catheter, Continuous Flush GENERIC NAME Class II (21 CFR 870.1210) and Class II 21 CFR870.4450 CLASSIFICATION SUBMITTED BY Micro Therapeutics, Inc. CONTACT M 2 Goodyear Regulatory Affairs (949) 837-3700 Irvine, CA 92618 PREDICATE MTI Titan™ Micro Catheter (K022003) DEVICE(S) MTI Rebar® Micro Catheter (K993672) The MTI Nautica™ Micro Catheter is an end-hole, single-lumen DEVICE catheter designed to be introduced over a steerable guidewire into the DESCRIPTION vasculature. The catheter has a semi-rigid proximal shaft which transitions into the flexible distal shaft to facilitate the advancement of the catheter in the anatomy. Dual radiopaque markers at the distal end facilitate fluoroscopic visualization. The outer surface of the catheter is coated to increase lubricity. INDICATIONS The MTI Nautica™ Micro Catheter is intended to access peripheral FOR USE and neuro vasculature for the controlled selective infusion of physician-specified therapeutic agents such as embolization materials and of diagnostic materials such as contrast media. Not intended for use in the coronary vasculature. TESTING In-vitro performance testing of the MTI Nautica™ Micro Catheter included dimensional inspection, tensile strength tests, burst pressure tests, flow rate tests, torque tests and performance under simulated conditions. The biocompatibility of the MTI Nautica™ Micro Catheter was verified in accordance with ISO 10993-1. Biological Evaluation of Medical Devices. Test results confirmed biocompatibility of the catheter was tested as an external communicating, blood contact, limited exposure (<24 hrs) device. The MTI Nautica™ Micro Catheter is substantially equivalent to the SUMMARY OF SUBSTANTIAL predicate devices in intended use and principles of operation.
