Abstract
A medical device for treating a heart having a faulty heart valve is disclosed. The medical device comprises a ligature including a first anchoring member and a second anchoring member is used. The ligature is percutaneously deployable into a patient with a faulty heart valve wherein the first anchoring member to anchor to a first tissue area of the heart and the second anchoring member to anchor to a second tissue area of the heart.
Claims20
A method of constricting a heart valve of a patient comprising:
- providing a medical device comprising:
- a delivery shaft having a delivery lumen, a proximal end, and a distal end, said delivery shaft further comprising a first deployment shaft and a second deployment shaft disposed within said delivery lumen, said delivery shaft further comprising a ligature releasably coupled thereto, said ligature having a first anchoring member and a second anchoring member;
- and
- a delivery handle coupled to the delivery shaft and having a first deployment mechanism and a second deployment mechanism wherein said first deployment mechanism is coupled to said first deployment shaft and said second deployment mechanism is coupled to said second deployment shaft;
- and
- deploying said ligature into said patient wherein said first deployment shaft deploys said first anchoring member to a first tissue area around said heart valve and said second deployment shaft deploys said second anchoring member to a second tissue area of said heart valve, and wherein said deploying anchors said first anchoring member to said first tissue area and said second anchoring member to said second tissue area.

A method of constricting a heart valve of a patient comprising:
- providing a medical device comprising a delivery shaft having a delivery lumen, a proximal end, and a distal end, said delivery shaft further comprising:
- a first deployment shaft and a second deployment shaft disposed within said delivery lumen;
- and
- a delivery handle coupled to the deliver shaft and having a first deployment mechanism and a second deployment mechanism wherein said first deployment mechanism is coupled to said first deployment shaft and said second deployment mechanism is coupled to said second deployment shaft;
- coupling a first ligature to said delivery shaft and deploying said first ligature to a heart valve area of said patient;
- coupling a second ligature to said delivery shaft and deploying said second ligature to said heart valve area of said patient;
- wherein each ligature of said first ligature and second ligature has a first anchoring member and a second anchoring member;
- and
- wherein said first deployment shaft deploys said first anchoring member to anchor said first anchoring member to said heart valve area to constrict said heart valve, said second deployment shaft deploys said second anchoring member to anchor said second anchoring member to said heart valve area to constrict said heart valve.

A method of constricting a ventricle of a patient comprising:
- providing a medical device comprising:
- a delivery shaft having a delivery lumen, a proximal end, and a distal end, said delivery shaft further comprises a first deployment shaft and a second deployment shaft disposed within said delivery lumen, said delivery shaft further comprises a ligature releasably coupled thereto, said ligature having a first anchoring member and a second anchoring member;
- and
- a delivery handle coupled to the deliver shaft and having a first deployment mechanism and a second deployment mechanism wherein said first deployment mechanism is coupled to said first deployment shaft and said second deployment mechanism is coupled to said second deployment shaft;
- and
- deploying said ligature into the heart of said patient wherein said first deployment shaft deploys said first anchoring member to a first tissue area of said ventricle and said second deployment shaft deploys said second anchoring member to a second tissue area of said ventricle, wherein said deploying anchors said first anchoring member to said first tissue area and said second anchoring member to said second tissue area.

A method of constricting a mitral valve of a patient comprising:
- providing a medical device comprising:
- a delivery shaft having a delivery lumen, a proximal end, and a distal end, said delivery shaft further comprises a first deployment shaft and a second deployment shaft disposed within said delivery lumen, said delivery shaft further comprises a ligature releasably coupled thereto, said ligature having a first anchoring member and a second anchoring member;
- and
- a delivery handle coupled to the delivery shaft and having a first deployment mechanism and a second deployment mechanism wherein said first deployment mechanism is coupled to deploy said first deployment shaft and said second deployment mechanism is coupled to said second deployment shaft;
- deploying said ligature is within a coronary sinus that substantially encircles said mitral valve;
- deploying said first anchoring member to a first tissue area around said mitral valve;
- and
- deploying said second anchoring member to a second tissue area around said mitral valve,
- wherein said first deployment shaft deploys and anchors said first anchoring member to said first tissue area and said second deployment shaft deploys and anchors said second anchoring member to said second tissue area.
