A cannulation system for cardiac support uses an inner cannula disposed within an outer cannula. The outer cannula includes a fluid inlet for placement within the right atrium of a heart. The inner cannula includes a fluid inlet extending through the fluid inlet of the outer cannula and the atrial septum for placement within at least one of the left atrium and left ventricle of the heart. The cannulation system also employs a pumping assembly coupled to the inner and outer cannulas to withdraw blood from the right atrium for delivery to the pulmonary artery to provide right heart support, or to withdraw blood from at least one of the left atrium and left ventricle for delivery into the aorta to provide left heart support, or both.

Left and right side heart support

The subject invention provides devices and methods for closing and sealing an opening in a conduit. The subject devices consist of an implantable flexible member adapted to conform to and seal with an inner surface of a conduit and further adapted to utilize the internal conduit pressure exerted thereon to form a substantially fluid-tight seal with the inner surface of the conduit whereby substances are prevented from leaking from the opening under normal physiological conditions. In the subject methods, a subject device is provided and positioned inside a conduit, operatively aligned over an opening to be sealed. The device is conformed to and sealed with an inner surface of the conduit and a substantially fluid-tight seal is formed between the device and the inner surface of the conduit utilizing the internal conduit pressure whereby substances within the conduit are prevented from leaking from the opening under normal physiological conditions.

Devices and methods for interconnecting conduits and closing openings in tissue

The present invention provides implantable devices and associated methods for interconnecting human vessels in a side-to-side or an end-to-side arrangement rapidly, safely and in a minimally invasive manner. The devices comprise a vessel connector and a intravascular support mechanism for establishing fluid communication between two vessels. Certain embodiments further include a sealing member for further sealing the openings in the vessels created for inserting the subject devices.

Devices and methods for interconnecting vessels

The present invention provides an implant device and an associated method for interconnecting human vessels rapidly, safely and in a minimally invasive manner. The device comprises a first segment, a second segment, and a flow opening along the periphery of the two connected segments. The first and second segments are bendable for easy insertion into an incision made within each vessel. Upon release, each bendable segment subsequently conforms to the interior walls of a vessel to provide a sealing contact along the contact surface of the segment inserted within. The flow opening provides fluid interconnectivity between the vessels connected by the implant device. The device is configured so as to: (1) not impede flow inside a vessel; (2) prevent flow out of the openings in the vessels except for flow from one vessel to another via the connector opening; and (3) force the vessels toward each other at areas around the openings allowing the vessels to grow together so that flow in one vessel may flow to the other. The implant device may be inserted using special catheter designed specifically for the placement and release of the implant device within the vessels for interconnection thereof. The implant device is preferably provided in an assortment of sizes, shapes, configurations, etc. in order to interconnect vessels of various sizes, shapes and orientations. A system which includes a catheter having the implantable device loaded therein is also disclosed

Device for interconnecting vessels in a patient

The present invention provides implantable devices and associated methods forinterconnecting human vessels in a side-to-side or an end-to-side arrangement rapidly, safely and in a minimally invasive manner. The devices comprises at least a first segment, a second component, and a flow opening between the at least one segment and the second component when operatively used. The first segment is flexible and has physical and mechanical properties which allow it to be easily inserted into a vessel, to conformably seal with the inside wall of the vessel and to be resistant to dislodging from the vessel. The second component may comprise a second segment having the same or a similar configuration as the first segment or may be a tubular member which extends from the first segment. The first and second segments are flexible for easy insertion into an incision made within the side of each vessel. Upon release from a constricted state, each flexible segment subsequently conforms to the interior walls of a vessel to provide a sealing contact along the contact surface of the segment inserted within. The tubular member is configured to be inserted into a transected end of a vessel. The flow opening provides fluid interconnectivity between the vessels connected by the implanted devices. The devices are configured so as to: (1) not impede flow inside a vessel; (2) prevent leakage from the incisions within the vessels; and (3) apposition the vessels toward each other allowing the vessels to heal together so that flow in one vessel may flow to the other.
