Prosthetic Valve Implantation Systems

Abstract

Prosthetic valves implantation methods and systems, especially as related to fitting a prosthetic valve at the site of a native stenotic or incompetent valve are described. The subject devices, systems and associated dock deployment and implant docking techniques may be employed in percutaneous valve replacement procedures.

1 . A medical apparatus, comprising:
 a prosthetic valve support structure; and   a docking sleeve configured to interface with the support structure and configured for implantation within a blood vessel of a patient.   
     
     
         2 . The medical apparatus of  claim 1 , wherein the docking sleeve is configured to displace the native anatomy. 
     
     
         3 . The medical apparatus of  claim 1 , wherein the docking sleeve is configured to provide a seal with the native anatomy. 
     
     
         4 . The medical apparatus of  claim 1 , wherein the docking sleeve is configured to anchor against the native anatomy. 
     
     
         5 . The medical apparatus of  claim 1 , wherein the docking sleeve comprises a tissue graft. 
     
     
         6 . The medical apparatus of  claim 1 , wherein the docking sleeve has an inner lumen with a regular cross-sectional shape. 
     
     
         7 . The medical apparatus of  claim 1 , further comprising:
 an elongate member;   an expandable member coupled with the elongate member, the expandable member configured to deploy the docking sleeve.   
     
     
         8 . The medical apparatus of  claim 1 , wherein the docking sleeve is configured to transition from an undeployed state suitable for advancement through the vasculature of a patient to a deployed state. 
     
     
         9 . The medical apparatus of  claim 1 , wherein the docking sleeve is compliant. 
     
     
         10 . The medical apparatus of  claim 1 , wherein the docking sleeve comprises an inner sleeve and an outer sleeve. 
     
     
         11 . The medical apparatus of  claim 10 , wherein the docking sleeve further comprises a spring member coupled between the inner sleeve and the outer sleeve. 
     
     
         12 . The medical apparatus of  claim 10 , further comprising a sealing member configured to seal a space between the inner and outer sleeves. 
     
     
         13 . The medical apparatus of  claim 10 , wherein at least one of the inner sleeve and the outer sleeve comprises a plurality of hinges. 
     
     
         14 . The medical apparatus of  claim 10 , wherein at least one of the inner sleeve and the outer sleeve comprises a plurality of deflectable panels. 
     
     
         15 . The medical apparatus of  claim 10 , wherein the outer sleeve comprises an aperture configured to receive the inner sleeve. 
     
     
         16 . The medical apparatus of  claim 1 , wherein the docking sleeve is coupled to the valve support structure by a spring member. 
     
     
         17 . The medical apparatus of  claim 16 , wherein the spring member is configured to center the valve support structure. 
     
     
         18 . The medical apparatus of  claim 1 , further comprising a sealing member configured to seal a space between the valve support structure and the docking sleeve. 
     
     
         19 . The medical apparatus of  claim 1 , wherein the valve support structure and docking sleeve are each configured to transition from an undeployed state suitable for advancement through the vasculature of a patient to a deployed state. 
     
     
         20 . The medical apparatus of  claim 11 , wherein the docking sleeve is configured to transition from a tri-star configuration.
