First Claim
Patent Images
1. A delivery device usable to cut a hole in a valve leaflet and attach a valve implant to the leaflet, comprising:
- a leaflet capture mechanism constructed and arranged to attain an operational grasp of the valve leaflet;
a cutting mechanism constructed and arranged to cut valve leaflet tissue while the valve leaflet is being grasped by the leaflet capture mechanism;
a delivery mechanism constructed and arranged to release a valve implant in operational proximity to a cut leaflet and attach the valve implant thereto; and
, a handle, operationally attached to the leaflet capture mechanism, the cutting mechanism, and the delivery mechanism, such that an operator has control over any actions taken by said mechanisms.

Abstract
A device and method for improving flow through a native blood vessel valve, such as the aortic valve, are provided. The present invention allows a miniature valve to be implanted into affected leaflets percutaneously, obviating the need for coronary bypass surgery. The method includes the cutting of small holes, on the order of 4 mm, in the leaflets of a targeted valve, thereby allowing blood to flow through the newly formed holes. The holes are used as attachment sites for the miniature valves of the present invention.
