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.
Claims14
A medical device comprising:
- a first anchoring member to anchor to a cardiac tissue and a second anchoring member to anchor to the cardiac tissue;
- a ligature coupling the first anchoring member and the second anchoring member;
- a catheter having a size suitable for percutaneous insertion through a blood vessel and the catheter operable to be maneuvered through the blood vessel to the cardiac tissue, the catheter comprising a proximal end and a distal end and a lumen therethrough, the catheter configured to accommodate the ligature therein;
- and
- a delivery handle coupled to the proximal end of the catheter, wherein the delivery handle comprises a deployment mechanism to deploy the ligature from the catheter,
- wherein the delivery handle comprises a first deployment mechanism and a second deployment mechanism wherein the first deployment mechanism is configured for a dedicated deployment of the first anchoring member and the second deployment mechanism is configured for a dedicated deployment of the second anchoring member.
3 more elements
A medical device comprising:
- a ligature comprising an anchoring member at each end, the ligature of a size suitable to constrict or reduce a size of a valve of a heart and each anchoring member operable to couple to tissue and secure the ligature;
- a catheter coupled with the ligature and the catheter having a size suitable for percutaneous insertion through a blood vessel and the catheter operable to be maneuvered through the blood vessel to the heart, the catheter comprising a proximal end and a distal end and a lumen therethrough a distal portion of which is sized to accommodate the ligature;
- a delivery mechanism coupled to the proximal end of the catheter comprising a first deployment shaft to deploy a first anchoring member of the ligature and a second deployment shaft to deploy a second anchoring member of the ligature;
- and
- a handle coupled to the proximal end of the catheter, further comprising a first deployment mechanism and a second deployment mechanism, wherein the first deployment mechanism is configured for a dedicated deployment of the first anchoring member and the second deployment mechanism is configured for a dedicated deployment of the second anchoring member.

A medical device comprising:
- a ligature comprising an anchoring member at each end, the ligature of a size suitable to constrict or reduce a size of a valve of a heart and each anchoring member operable to couple to tissue and secure the ligature;
- a catheter coupled with the ligature and the catheter having a size suitable for percutaneous insertion through a blood vessel and the catheter operable to be maneuvered through the blood vessel to the heart, the catheter comprising a proximal end and a distal end and a lumen therethrough a distal portion of which is sized to accommodate the ligature;
- and
- a delivery mechanism coupled to the proximal end of the catheter comprising a first deployment shaft to deploy a first anchoring member of the ligature and a second deployment shaft to deploy a second anchoring member of the ligature,
- wherein the delivery mechanism further comprises a first rotating mechanism and a second rotating mechanism wherein the first rotating mechanism can rotate the first anchoring member accommodated at the distal end of the catheter and the second rotating mechanism can rotate the second anchoring member accommodated at the distal end of the catheter.
