• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 870.4450

• Attributes: Therapeutic

Intended Use

The KAVS Catheter is intended to temporarily inhibit blood flow in isolated sections of peripheral veins in order to inject physician prescribed medications.

Device Story

KAVS Catheter is a double-lumen, radio-opaque polyurethane intravascular catheter with a distal latex balloon. Used in clinical settings, it is advanced into a peripheral vein via phlebotomy or introducer sheath under ultrasound guidance. The physician positions the catheter tip at the vascular area of interest; the balloon is then inflated with sterile saline (0.9%) to temporarily occlude blood flow in that segment. This isolation prevents the prescribed medication, injected through the central lumen, from being washed away by normal blood flow, ensuring controlled contact time with the venous wall. After treatment, the medication is aspirated, the balloon is deflated, and the catheter is removed. The device benefits patients by enabling localized, targeted therapeutic delivery within peripheral veins.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Double-lumen coaxial catheter; materials: radio-opaque polyurethane (catheter body), latex (distal balloon). Features: rounded closed tip, three outlet openings for medication delivery, proximal double attachment with Luer-lock adapters (one for medication, one with stopcock for balloon inflation). Dimensions: not specified. Energy source: manual (saline inflation). Connectivity: none. Sterilization: not specified.

Indications for Use

Indicated for patients requiring temporary blood flow inhibition in isolated peripheral vein segments to facilitate the administration of physician-prescribed medications.

Regulatory Classification

Identification

A vascular clamp is a surgical instrument used to occlude a blood vessel temporarily.

#### d. Description

The KAVS catheter is an intravascular catheter that is introduced into the patient's vein for short-term therapeutic use. The catheter has a balloon at the distal end, that when expanded, will temporarily block the blood flow in that segment of the vein. This allows the physician to inject medication through the central lumen of the catheter for patient treatment. Once the treatment is complete the physician can then remove the medication, prior to removing the catheter.

Procedure: The catheter is advanced through a phlebotomy (incision in the vein under observation) or through an introducer sheath under ultrasound control, into the vein. The ultrasound control and radio-opaque catheter allow the physician to guide the catheter until the tip is positioned at the vascular area of interest. Once this position is verified, under ultrasound, the balloon is filled with a sterile saline solution (0.9%), until the blood flow is blocked. The maximum filling volume of the balloon, as identified in the

{1}------------------------------------------------

user guide, should not be exceeded in order to prevent possible balloon perforations. The prescribed medication is then administered through the central lumen and will rno procensbur medication in the tip of the catheter. Once the medication has had adequate contact time, the medication can then be aspirated and removed from the patient. The balloon is then emptied, through the separate balloon lumen, and the catheter is removed from the patient.

The KAVS Catheter prevents the prescribed medication from being washed away by normal blood flow. This results in a controlled contact time of the medication with the venous wall for an improved therapeutic use.

The KAVS catheter is a double-lumen catheter made of radio-opaque polyurethane, which is equipped with a latex balloon at the distal end. At the proximal end of the coaxial catheter there is a double attachment, consisting of a Luer-lock adapter for access to the main catheter lumen, for injection of prescribed medication, and a laterally mounted Luer-lock adapter with a stopcock for filling the balloon. The rounded catheter tip is closed, underneath the balloon there are three openings, which serve as outlet openings for the main catheter lumen.

#### Intended use e.

The KAVS Catheter is intended to temporarily inhibit blood flow in isolated sections of peripheral veins in order to inject physician prescribed medications.

## Summary of technological considerations f.

The KAVS Catheter is substantially equivalent to the predicate devices. Both catheters are designed to block the blood flow in order to inject a prescribed medication for therapeutic use. The KAVS Catheter is as safe, as effective, and performs as well as or better than the predicate device. 807.92(b)(3).
