What is the Cutting Catheter?
The Cutting Catheter is a percutaneous device for scoring diseased aortic valves as a non-occlusive preparatory step for percutaneous aortic valve replacement. By scoring the existing diseased valve, the device will enhance placement and positioning of artificial valves, thus improving the efficacy of percutaneous aortic valve replacement.

How does it work?

The catheter is positioned in the left ventricle by navigating the aortic arch, and is anchored in the aortic root. The blades are then deployed and pulled back across the valve, scoring the leaflets. Once the cut is complete, the blades are contracted and the device is resheathed and retrieved from the body.


Cutting Catheter Background
Currently, balloon valvuloplasty is used in preparation for Percutaneous Aortic Valve Replacement (PAVR). However, valvuloplasty procedures block blood flow to the aorta, and perform poorly.

The cutting assembly is key to the Cutting Catheter’s design and function. It comprises of three laser-cut blades for steady scoring of calcified valves and an aortic root anchor that anchors the catheter at the aortic annulus.

The procedure is controlled by an elegant and simple handle. Use of the Cutting Catheter is broken down into a series of steps that are carried out using various components of the handle.

Procedural Use
The procedure for scoring valves with the Cutting Catheter is simple and can be repeated with minimal variation. The Cutting Catheter improves prosthetic valve placement and helps minimize risk of paravalvular leakage.
