Device features semi-rigid proximal shaft transitioning to flexible distal shaft to facilitate anatomical advancement; dual radiopaque markers at distal end allow fluoroscopic visualization; outer surface coated for increased lubricity. Used by physicians in clinical settings to deliver therapeutic agents or contrast media. Device is introduced over a steerable guidewire. Benefits include precise, controlled delivery of materials to target vascular sites. ## Clinical Evidence Bench testing only. In-vitro performance testing included dimensional inspection, tensile strength, burst pressure, flow rate, torque tests, and performance under simulated conditions. 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. Class II device (21 CFR 870.1210, 870.4450). ## 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 Echelon™ Micro Catheter ([K030688](/device/K030688.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

DEVICE(S) | MTI Echelon™ Micro Catheter (K030688) | | | DEVICE
DESCRIPTION | The MTI Echelon™ Micro Catheter is an end-hole, single-lumen
catheter designed to be introduced over a steerable guidewire into the
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
FOR USE | The Echelon™ Micro Catheter is intended to access peripheral 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.
This is the same intended use as predicate device Echelon Micro
Catheter K030688. | | | TESTING | In-vitro performance testing of the MTI Echelon™ 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 Echelon™ 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. | | | SUMMARY OF
SUBSTANTIAL
EQUIVALENCE | The MTI Echelon™ Micro Catheter is substantially equivalent to the
predicate devices in intended use and principles of operation. | | {1}------------------------------------------------ DEPARTMENT OF HEALTH & HUMAN SERVICES Public Health Service Image /page/1/Picture/2 description: The image shows the logo for the U.S. Department of Health & Human Services.

You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
