Treatments for a patient with congestive heart failure
First Claim
1. A minimally invasive method of treating a patient heart having mitral valve regurgitation from a left ventricle, comprising:
- a. forming a small passageway in the patient'"'"'s left ventricular wall defining in part the patient'"'"'s left ventricle;
b. seating a valve into the passageway formed in the left ventricular wall;
c. advancing a grasping device through the valve into the left ventricle;
d. advancing an valve leaflet stabilizer member through the valve, through the left ventricle, through the mitral valve into a left atrium distal to the mitral valve;
e. expanding the stabilizer member within the left atrium and engaging leaflets of the mitral valve and guiding the leaflets to a grasping location;
f. grasping the leaflets in the grasping location with the grasping device; and
g. securing together free edges of the grasped leaflets with at least one connecting member.

Abstract
The invention is directed to two minimally invasive therapeutic procedures, particularly for patients with congestive heart failure, and devices and systems for such procedures. One procedure involves providing a valved passageway through the patient'"'"'s left ventricular wall at the apex of the patient'"'"'s heart and advancing instruments through the valved passageway to connect the valve leaflets of the patient'"'"'s heart valve, e.g. the mitral valve, in a “Bow-Tie” configuration to prevent or minimize regurgitation through the valve. The second procedure involves advancing a pacing lead and a pacing lead implanting device through a trocar in the patient'"'"'s chest and implanting the pacing lead on an exposed epicardial region of the patient'"'"'s heart wall. The pacing lead has a penetrating electrode which is secured within the heart wall. One or both procedures may be performed on a patient with CHF. Improved devices for these procedures include a minimally invasive grasping device having an inner lumen for advancing connecting members and other instruments through the device to the distal end thereof. Other improved devices include a pacing lead implant instrument which is releasably secured by its distal end to the exposed heart wall to facilitate penetration of the pacing lead electrode into the heart wall. Other improved instruments include a leaflet connector with an artificial cordae tendenae strand secured to an end of the leaflet connector.

53. A method for treating a patient having a regurgitating heart valve, comprising:
-
a. securing together free edges of the patient'"'"'s regurgitating heart valve in a “
Bow-Tie”
configuration from within the patient'"'"'s heart; and
b. securing one end of an artificial cordae tendenae to the free edges of the heart valve and another end to a heart wall which defines in part a heart chamber. - View Dependent Claims (54)

55. A minimally invasive system for treating a patient'"'"'s heart, comprising:
-
a. a valve body which is configured to be secured within a passageway formed through a wall of the patient'"'"'s heart which defines in part a heart chamber and which has a valve element within the valve body which allows passage of an instrument through the valve element into a chamber of the patient'"'"'s heart defined in part by the heart wall without significant blood loss through the valve element;
b. a tissue grasping device which is configured to extend through the valve element within the valve body secured within the passageway in the patient'"'"'s heart wall and which has at least two grasping members configured to grasp valve leaflets; and
c. a tissue connecting member to connect free edges of valve leaflets. - View Dependent Claims (56, 57, 58, 59, 60)
