Abstract

Abstract A method for treatment of mitral annulus dilatation comprises reducing the circumference of the mitral valve annulus. The method further comprises inserting an elongate body into the coronary sinus in the vicinity of the posterior leaflet of the mitral valve, fixing the position of the elongate body relative to the coronary sinus, and changing the shape of the elongate body in order to remodel the mitral valve annulus.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 92 words
A device for treating mitral valve dilatation configured to be placed in the coronary sinus of a heart adjacent to the mitral valve annulus, the device comprising an elongate body made at least in part of a memory metal, wherein the elongate body is configured to asymmetrically contract after placement in the coronary sinus such that the elongate body applies a force along a portion of the atrial wall of the coronary sinus adjacent to the mitral valve annulus to press the coronary sinus against a portion of the mitral valve annulus.
Claim 2
Independent Claim 92 words
A device for treating mitral valve dilatation configured to be placed in the coronary sinus of a heart adjacent to the mitral valve annulus, the device comprising an elongate body made at least in part of a memory metal, wherein the elongate body is configured to asymmetrically contract after placement in the coronary sinus such that the elongate body applies a force along a portion of the atrial wall of the coronary sinus adjacent to the mitral valve annulus to press the coronary sinus against a portion of the mitral valve annulus.
Claim 3
Dependent Claim 37 words
The device of claim 1 wherein at least a portion of the elongate body comprises an expandable structure that expands from a collapsed condition to an expanded condition for engagement with the walls of the coronary sinus.
Claim 4
Dependent Claim 13 words
The device of claim 2 wherein the expandable structure is a stent section.
Claim 5
Dependent Claim 13 words
The device of claim 2 wherein the expandable structure is cylindrical in configuration.
Claim 6
Dependent Claim 25 words
The device of claim 1 wherein the elongate body applies the force to a plurality of portions of the atrial wall of the coronary sinus.
Claim 7
Dependent Claim 40 words
The device of claim 1 , wherein the elongate body further comprises a proximal stent section and a distal stern section and wherein the proximal and distal stent sections are expandable for engagement with the walls of the coronary sinus.
Claim 8
Dependent Claim 18 words
The device of claim 6 , wherein the proximal and distal stent sections are joined by a wire.
Claim 9
Dependent Claim 37 words
The device of claim 7 , further comprising a first eyelet fixed to the proximal stent section and a second eyelet fixed to the distal stent section, wherein the wire extends through the first and second eyelets.
Claim 10
Independent Claim 86 words
A method of treating dilatation of a mitral valve annulus including delivering a mitral valve therapy device through a venous system to a coronary sinus and deploying the device such that a distal end of the device is spaced distally from a proximal end of the device, wherein the device applies a force to a portion of an atrial wall of a coronary sinus to press the coronary sinus against a portion of the mitral valve annulus to change the shape of the mitral valve annulus.
Claim 11
Independent Claim 86 words
A method of treating dilatation of a mitral valve annulus including delivering a mitral valve therapy device through a venous system to a coronary sinus and deploying the device such that a distal end of the device is spaced distally from a proximal end of the device, wherein the device applies a force to a portion of an atrial wall of a coronary sinus to press the coronary sinus against a portion of the mitral valve annulus to change the shape of the mitral valve annulus.
Claim 12
Dependent Claim 46 words
The method of claim 9 wherein the deploying step comprises retracting a cover sheet to expose the device in the coronary sinus, the device being formed of a memory material and configured for applying the force to press the coronary sinus against the mitral valve annulus.
Claim 13
Dependent Claim 55 words
The method of claim 9 wherein the device is expandable from a collapsed condition to a deployed condition, wherein the delivering step is carried out while the device is in the collapsed condition, and wherein the deploying step further includes expanding the device after the device is delivered at least partially into the coronary sinus.
Claim 14
Dependent Claim 23 words
The method of claim 9 wherein the force is applied to a plurality of portions of the atrial wall of the coronary sinus.
Claim 15
Dependent Claim 50 words
The method of claim 12 wherein the mitral valve therapy device comprises an elongate body made at least in part of a memory material and sized for insertion into the coronary sinus, the elongate body being configured for applying the force to the plurality of portions of the coronary sinus.
Claim 16
Dependent Claim 58 words
The method of claim 13 wherein at least a portion of the elongate body is expandable from a collapsed condition to a deployed condition, wherein the delivering step is carried out while the device is in the collapsed condition, and wherein the deploying step further includes expanding the device after the device is delivered into the coronary sinus.
