Abstract

Abstract An assembly for effecting the condition of a mitral valve annulus includes a mitral valve therapy device, a coupling structure carried by the device, a catheter, a second coupling structure, and a locking member. To implant the device, the device is first releasably locked to a pushing member by the coupling structures and the locking member. When the device is positioned within the coronary sinus adjacent the mitral valve annulus and deployed, the coupling structures may be released from each other by the release of the locking member.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 83 words
A method of delivering a mitral valve therapy device into the heart, the method comprising: providing a therapy device comprising a first coupling structure; providing a delivery device with a second coupling structure; releasably locking the first and second coupling structures by passing a locking member through at least one of the first and second coupling structures; delivering the therapy device and the delivery device through a delivery catheter; and deploying the therapy device from the delivery catheter and into the coronary sinus.
Claim 2
Independent Claim 83 words
A method of delivering a mitral valve therapy device into the heart, the method comprising: providing a therapy device comprising a first coupling structure; providing a delivery device with a second coupling structure; releasably locking the first and second coupling structures by passing a locking member through at least one of the first and second coupling structures; delivering the therapy device and the delivery device through a delivery catheter; and deploying the therapy device from the delivery catheter and into the coronary sinus.
Claim 3
Dependent Claim 22 words
The method of claim 1 further comprising withdrawing the locking member to release the first coupling structure from the second coupling structure.
Claim 4
Dependent Claim 27 words
The method of claim 2 wherein withdrawing the locking member comprises proximally withdrawing the locking member to release the first coupling structure from the second coupling structure.
Claim 5
Dependent Claim 36 words
The method of claim 1 wherein passing a locking member through at least one of the first and second coupling structures comprises passing a pin through at least one of the first and second coupling structures.
Claim 6
Dependent Claim 22 words
The method of claim 1 wherein the releasably locking step comprises passing the locking member through the first and second coupling structures.
Claim 7
Dependent Claim 13 words
The method of claim 1 wherein the first coupling structure forms a loop.
Claim 8
Dependent Claim 20 words
The method of claim 1 wherein the first coupling structure is disposed at a proximal end of the therapy device.
Claim 9
Dependent Claim 20 words
The method of claim 1 wherein the second coupling structure is disposed at a distal end of the delivery device.
Claim 10
Independent Claim 94 words
A system to deliver a therapy device into the coronary sinus to treat mitral valve regurgitation, comprising: a therapy device adapted to be delivered into a coronary sinus, the therapy device comprising a first coupling structure; a delivery device comprising a second coupling structure; a locking member that releasably locks the first and second coupling structures, wherein the locking member passes through at least one of the first and second coupling structures to lock the first and second coupling structures; and a delivery catheter adapted to deliver the therapy device into the coronary sinus.
Claim 11
Independent Claim 94 words
A system to deliver a therapy device into the coronary sinus to treat mitral valve regurgitation, comprising: a therapy device adapted to be delivered into a coronary sinus, the therapy device comprising a first coupling structure; a delivery device comprising a second coupling structure; a locking member that releasably locks the first and second coupling structures, wherein the locking member passes through at least one of the first and second coupling structures to lock the first and second coupling structures; and a delivery catheter adapted to deliver the therapy device into the coronary sinus.
Claim 12
Dependent Claim 20 words
The system of claim 9 wherein the first coupling structure is disposed at a proximal end of the therapy device.
Claim 13
Dependent Claim 20 words
The system of claim 9 wherein the second coupling structure is disposed at a distal end of the delivery device.
Claim 14
Dependent Claim 25 words
The system of claim 9 wherein the locking member passes through the first and second coupling structures to lock the first and second coupling structures.
Claim 15
Dependent Claim 13 words
The system of claim 9 wherein the first coupling structure comprises a loop.
Claim 16
Dependent Claim 13 words
The system of claim 9 wherein the second coupling structure comprises a loop.
