Abstract
Abstract A medical apparatus and method for remodeling a mitral valve annulus adjacent to the coronary sinus includes an elongate body having a proximal end and a distal end. The elongate body is movable from a first, flexible configuration for transluminal delivery to at least a portion of the coronary sinus to a second configuration for remodeling the mitral valve annulus.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
133 words
A medical apparatus for remodeling a mitral valve annulus adjacent to the coronary sinus, comprising: an elongate body, having a proximal end and a distal end, the elongate body being movable from a first, flexible configuration for transluminal delivery to at least a portion of the coronary sinus to a second configuration for remodeling the mitral valve annulus; and a forming element attached to the elongate body for manipulating the elongate body from the first delivery configuration to the second remodeling configuration; wherein the elongate body in the remodeling configuration comprises proximal and distal segments which are each concave in a first direction and a central segment which is concave in a second direction and wherein at least in the remodeling configuration the forming element extends outside the body along the central segment.
Claim 2
Dependent Claim
133 words
A medical apparatus for remodeling a mitral valve annulus adjacent to the coronary sinus, comprising: an elongate body, having a proximal end and a distal end, the elongate body being movable from a first, flexible configuration for transluminal delivery to at least a portion of the coronary sinus to a second configuration for remodeling the mitral valve annulus; and a forming element attached to the elongate body for manipulating the elongate body from the first delivery configuration to the second remodeling configuration; wherein the elongate body in the remodeling configuration comprises proximal and distal segments which are each concave in a first direction and a central segment which is concave in a second direction and wherein at least in the remodeling configuration the forming element extends outside the body along the central segment.
Claim 3
Dependent Claim
22 words
A medical apparatus as in claim 1 , wherein the elongate body comprises a tube having a plurality of transverse slots therein.
Claim 4
Dependent Claim
20 words
A medical apparatus as in claim 1 , further comprising a lock for retaining the body in the remodeling configuration.
Claim 5
Dependent Claim
35 words
A medical apparatus as in claim 1 , wherein the apparatus is movable from the delivery configuration to the remodeling configuration in response to proximal retraction of at least a portion of the forming element.
Claim 6
Dependent Claim
35 words
A medical apparatus as in claim 1 , wherein the apparatus is movable from the delivery configuration to the remodeling configuration in response to distal advancement of at least a portion of the forming element.
Claim 7
Dependent Claim
21 words
A medical apparatus as in claim 1 , further comprising at least one anchor for engaging a site within a vessel.
Claim 8
Dependent Claim
23 words
A medical apparatus as in claim 6 , wherein the anchor comprises at least one barb for piercing the wall of the vessel.
Claim 9
Dependent Claim
26 words
A medical apparatus as in claim 6 , comprising a first tissue anchor at the proximal end and a second tissue anchor at the distal end.

An implant for positioning within a patient, comprising: a deployment catheter; an elongate flexible body having a proximal section, a central section and a distal section; a forming element extending through at least the proximal and distal sections of the body; and a detachable coupling on the body, for removably attaching the body to the deployment catheter; wherein manipulation of the forming element deflects the central section laterally with respect to at least a portion of the proximal and distal sections to selectively apply a compressive force along a region of tissue.
Claim 13
Dependent Claim
92 words
An implant for positioning within a patient, comprising: a deployment catheter; an elongate flexible body having a proximal section, a central section and a distal section; a forming element extending through at least the proximal and distal sections of the body; and a detachable coupling on the body, for removably attaching the body to the deployment catheter; wherein manipulation of the forming element deflects the central section laterally with respect to at least a portion of the proximal and distal sections to selectively apply a compressive force along a region of tissue.
Claim 14
Dependent Claim
14 words
An implant as in claim 11 , wherein the body comprises a tubular wall.
Claim 15
Dependent Claim
22 words
An implant as in claim 12 , wherein the tubular wall is substantially noncompressible along a first side of the central section.
Claim 16
Dependent Claim
32 words
An implant as in claim 13 comprising a plurality of voids in the wall along a second side of the central section, thereby permitting axial shortening or elongation of the second side.
Claim 17
Dependent Claim

Claim 22
Dependent Claim
53 words
An implant as in claim 11 , wherein manipulation of the forming element introduces a first curve in the central section of the body which is concave in a first direction, and at least a second curve in one of the proximal and distal sections of the body concave in a second direction.
Claim 23
Dependent Claim
20 words
