US 6,458,140 B2 · Devices and methods for interconnecting vessels

Abstract

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.

Dependent claims

A device for performing an anastomosis wherein the device is implantable to a site within a vessel of a subject through an artificially-made opening in the vessel, comprising:

a first segment comprised of a compliant material and having a configuration whereby the first segment is constrictable to a size sufficient to fit through the artificial opening and is expandable to be securely and permanently self-retained within the vessel upon implantation, the first segment comprising:
a vessel-contacting surface and
a lumen-facing surface,
wherein, upon implantation of the first segment, the vessel-contacting surface is adapted to readily conform to and seal with the inner surface of the conduit and wherein the lumen-facing surface is adapted to utilize the internal conduit pressure exerted thereon to form a substantially fluid-tight seal between the vessel-contacting surface and an inner surface of the conduit;
and
a second segment for implantation into a second vessel.
