Abstract

A system is provided for treating valvular disease percutaneously though a ventricular apex of the heart. The system includes a needle for piercing through the ventricular apex of the heart and creating a hole whereby a catheter can be passed through the skin and the wall of the heart to gain access to the interior of the heart. Once percutaneous access to the heart is obtained, any of a variety of techniques can be utilized for annular and/or valvular therapy and/or repair through, the catheter. A closure device is necessary for closing the puncture of the heart. Any of a variety of vascular closure devices can be modified to be utilized with the system to close the puncture of the ventricular apex of the heart.

Claims

1-30. -30. (canceled)

31. A method for treating valvular disease, the method comprising:

inserting a needle through the skin and a ventricular apex of the heart;

inserting a catheter into a ventricle of the heart through a hole in the ventricular apex of the heart created by inserting the needle;

inserting a valve repair device through the catheter and into the ventricle of the heart;

utilizing the valve repair device within the heart to repair a diseased valve;

inserting a closure device through the catheter; and

closing the hole in the ventricle of the heart created by the needle and catheter with the closure device.

32. The method of claim 31, wherein inserting a catheter into a ventricle of the heart through a hole in the ventricular apex of the heart created by inserting the needle comprises inserting a catheter suitable for insertion into an atrium of the heart, a pulmonary artery, or an aorta.

33. The method of claim 31, wherein inserting a valve repair device through the catheter comprises inserting at least one of:

a sheath compatible to be inserted through the catheter and operable to open and close when embedded within a valve of the heart;

a clip compatible to be inserted through the catheter and operable to open and close when embedded within a valve of the heart;

a radiofrequency device compatible to be inserted through the catheter and operable to apply radiofrequency energy to an annulus of a valve of the heart;

a suturing device compatible to be inserted through the catheter and operable to suture one or more leaflets of a valve of the heart;

a cinching device compatible to be inserted through the catheter and operable to cinch an annulus of a valve of the heart; and

a replacement valve compatible to be inserted through the catheter and operable to replace a valve of the heart.

34. The method of claim 31, wherein inserting a needle through a ventricular apex of the heart comprises inserting a needle through the left ventricular apex.

35. The method of claim 34, wherein the valvular disease is aortic valve disease or mitral valve disease.

36. The method of claim 31, wherein utilizing the valve repair device within the heart to repair a diseased valve comprises utilizing the valve repair device within the heart to repair an aortic valve or a mitral valve.

37. The method of claim 31, wherein inserting a needle through a ventricular apex of the heart comprises inserting a needle through a right ventricular apex.

38. The method of claim 37, wherein the valvular disease is tricuspid valve disease or pulmonic valve disease.

39. The method of claim 31, wherein utilizing the valve repair device within the heart to repair a diseased valve comprises utilizing the valve repair device within the heart to repair a tricuspid valve or a pulmonic valve.

40. The method of claim 31, wherein insertine a sheath compatible to be inserted through the catheter and operable to open and close when embedded within a valve of the heart comprises inserting a sheath configured to be embedded within the valve via one or more notches configured to catch on an annulus of a valve.

41. The method of claim 31, wherein inserting a catheter into a ventricle of the heart through a hole in the ventricular apex of the heart created by inserting the needle comprises inserting a catheter of at least 4-French size and not more than 36-French size.

42. The method of claim 31, wherein inserting a closure device through the catheter comprises inserting a vascular closure device modified to close a diameter of the hole created by the needle and/or catheter.

43. The method of claim 31, wherein inserting a closure device through the catheter comprises inserting a closure device that is coated with thrombin and/or collagen to aid in hemostasis.

44. The method of claim 31, wherein inserting a closure device through the catheter comprises inserting a closure device that is made of material that is reabsorbable by the body after hemostasis occurs.

45. The method of claim 31, further comprising using a monitoring system to monitor a heart function parameter.

46. The method of claim 45, wherein using a monitoring system to monitor a heart function parameter comprises performing intracardiac echocardiography, transesophageal echocardiography, or fluoroscopy.
