Abstract: A device and method for creating a connection with the left ventricle of a heart are provided. A seal member capable of moving between a folded position and an open position is attached to the end of a conduit. An introducer capable of moving between a first and second position allows for the expansion of the seal member into an open position. A clamp component is positioned outside of the heart to provide an axial clamping force with the wall of the heart so that a seal is created between the seal member and the wall of the heart.

Abstract: This invention is directed to a system and method for partitioning a patient's heart chamber into a productive portion and a non-productive portion which are particularly suitable for treating patients with congestive heart failure. The partitioning system has a plurality of partitioning devices with reinforced, expandable membranes which separate the productive and non-productive portions of the heart chamber. When deployed within the patient's heart chamber, the second partitioning device is off-set from the deployed first partitioning device to cover a region of the wall defining the patient's heart chamber which is not covered by the first partitioning device. The multiple partitioning devices may be independent from each other or may be interconnected, e.g. a tether or strand.

Abstract: A partitioning device for separating a patient's heart chamber into a productive portion and a non-productive portion which is suitable for treating patients with heart disease, particularly congestive heart failure. The partitioning device has a reinforced membrane with outwardly biased members to help seal the periphery of the membrane against the wall of the patient's heart chamber. In one embodiment, the outwardly biased member is an expansive strand that extends between adjacent ribs of an expandable frame which reinforces the membrane. In another embodiment, the outwardly biased member is a hydrophilic body such as foam which swells upon contact with body fluid such as blood in the heart chamber. The reinforced membrane has a central hub with a distally extending support stem with a plurality of feet which extend radially from a centerline axis and preferably have ends that are aligned in a common plane.

Abstract: This invention is directed to a partitioning device for separating a patient's heart chamber into a productive portion and a non-productive portion. The device is particularly suitable for treating patients with congestive heart failure. The partitioning device has a reinforced, expandable membrane which separates the productive and non-productive portions of the heart chamber and a support or spacing member extending between the reinforced membrane and the wall of the patient's heart chamber. The support or spacing member has a non-traumatic distal end to engage the ventricular wall.

Abstract: A method and a device for improving cardiac function are provided. The device is packaged in a collapsed state in an end of a catheter. Portions of a frame construction of the device spring outwardly when the catheter is withdrawn from the device. Anchoring formations on the frame construction secure the frame construction to a myocardium of the heart. A membrane secured to the frame construction then forms a division between volumes of an endocardial cavity of the heart on opposing sides of the membrane.

Abstract: A method and device for the treatment of a patient with heart disease and particularly a heart chamber having a myocardial rupture or characteristics of an incipient myocardial rupture. The heart chamber is partitioned so as to isolate a non-productive portion having a rupture or a region of an incipient rupture from a productive portion. The heart chamber is preferably partitioned with a reinforced membrane which has a pressure receiving surface that defines part of the productive portion of the heart chamber. The peripheral base of the reinforced membrane may have an eccentric configuration.

Abstract: The present methods provide access to high flow vessels without causing severe trauma for the patient. At the same time, the methods maximize the size of a vascular instrument that can be deployed at the target location. The methods involve tunneling through the patient's tissue to create an access path between a percutaneous access site and the target location by using a second percutaneous site that is generally subcutaneous.

Abstract: This invention is directed to a partitioning device for separating a patient's heart chamber into a productive portion and a non-productive portion. The device is particularly suitable for treating patients with congestive heart failure. The partitioning device has a frame-reinforced, expandable membrane which separates the productive and non-productive portions of the heart chamber. The proximal ends of the ribs of the frame have tissue penetrating elements about the periphery thereof which are configured to penetrate tissue lining the heart wall at an angle approximately perpendicular to a longitudinal axis of the partitioning device. The partitioning device has a hub with a non-traumatic distal end to engage the ventricular wall.
