Intended Use

The Pronto catheter is indicated for the removal of fresh, soft emboli and thrombi from vessels in the coronary and peripheral vasculature.

Device Story

Pronto V4 is a dual-lumen rapid exchange extraction catheter; used for removing fresh, soft emboli and thrombi from coronary and peripheral vessels. Device features stiff proximal region, flexible distal region, rounded distal tip with sloped extraction opening, and radiopaque marker band. Distal 18 cm has hydrophilic coating for deliverability. Operated by physicians in clinical settings; utilizes 30 mL syringes attached via extension line and stopcock to create aspiration for thrombus removal. Includes filter basket for collecting thrombus for lab analysis. Guidewire compatible (≤0.014 inches).

Clinical Evidence

Bench testing only. Verification testing included simulated anatomy/concomitant device use, hydrophilic coating integrity, thrombus aspiration, kink resistance, air aspiration, tensile, torque, and dimensional verifications. Biocompatibility and hemocompatibility assessments included cytotoxicity, sensitization, irritation, acute systemic toxicity, material-mediated pyrogens, hemolysis, coagulation, prothrombin time, hematological parameters, complement activation, and thrombogenicity. All results met acceptance criteria.

Technological Characteristics

Dual-lumen rapid exchange catheter; thermoplastics construction; hydrophilic coating; radiopaque marker band; ISO 594-1/594-2 compliant luer fittings; ethylene oxide sterilization. Available in 5.5F, 7F, and 8F sizes.

Indications for Use

Indicated for removal of fresh, soft emboli and thrombi from coronary and peripheral vasculature.

Regulatory Classification

Identification

Dear Mr. Nienstedt:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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.

#### Device Description

The Pronto V4 extraction catheter (Pronto) is a dual lumen rapid exchange catheter that has a working length of approximately 138 cm and is packaged with related accessories. The smaller wire lumen of the catheter is able to accommodate guidewires ≤0.014 inches in diameter. The larger extraction lumen allows for the removal of thrombus by use of the included 30 mL syringes through the extension line and stopcock. The catheter has a stiff proximal region and a flexible distal region. The catheter has a rounded distal tip with a protected, sloped opening of the extraction lumen to facilitate advancement of the catheter into the blood vessel and maximize extraction of thrombus

{5}------------------------------------------------

through the extraction lumen. The catheter contains a radiopaque marker band located approximately 2 mm from the distal tip. The distal 18 cm of the catheter has a hydrophilic coating to enhance deliverability to the target vasculature. The device has positioning marks located at 95 cm and 105 cm from the distal tip, respectively. The proximal end of the catheter incorporates a standard luer adapter to facilitate the attachment of catheter to the included extension line, stopcock, and 30 mL syringes. A filter basket is included for assistance in filtering the blood removed during the procedure for laboratory analysis of any thrombus.
