Abstract
Abstract An implantable valve having a valve element or leaflet and a base that is attachable to a vessel wall using a connector such as a screw, pin or a staple. The valve can be implanted using a catheter to position the valve in a desired location and drive the connector into the vessel wall. The valve can be used as a venous valve to control blood flow within the veins, arteries, heart or the aorta of a patient.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
97 words
A delivery catheter for a valve, comprising: a sheath; a catheter having a predetermined curved portion, the catheter at least partially positioned within the sheath; a valve having an opening; and a cannula having a sharp pointed tip and an aperture positioned proximal to the sharp pointed tip, the sharp pointed tip of the cannula extends at least partially from a distal end of the catheter through the opening of the valve, and the predetermined curved portion of the catheter positions the sharp pointed tip of the cannula substantially perpendicular to a longitudinal axis of the sheath.
Claim 2
Dependent Claim
97 words
A delivery catheter for a valve, comprising: a sheath; a catheter having a predetermined curved portion, the catheter at least partially positioned within the sheath; a valve having an opening; and a cannula having a sharp pointed tip and an aperture positioned proximal to the sharp pointed tip, the sharp pointed tip of the cannula extends at least partially from a distal end of the catheter through the opening of the valve, and the predetermined curved portion of the catheter positions the sharp pointed tip of the cannula substantially perpendicular to a longitudinal axis of the sheath.
Claim 3
Dependent Claim
