Assignee:

Medtronic AVE, Inc. - Santa Rosa CA

International Classification:

A61F 200

US Classification:

623 112, 623 123

Abstract:

A delivery catheter for a radially compressible tubular prosthesis comprises an elongate shaft slidably received within an elongate sheath. The prosthesis is carried over the distal end of the shaft where it is contained in a radially compressed configuration by the sheath. After introducing the catheter to a desired target location within a body lumen, the prosthesis may be released by proximally retracting the sheath. The prosthesis will remain anchored to the shaft during at least part of the release procedure, permitting the user to recapture the prosthesis by distally advancing the sheath.

International Classification:

A61M 2904

US Classification:

606192, 601 41, 600207, 604 98

Abstract:

A minimally invasive device for performing direct cardiac massage including an inflatable bladder mounted on a rigid inflation tube. The rigid inflation tube is used to push the bladder into the sternocostal space through an incision in the upper abdomen just below the xiphoid process. After insertion into the sternocostal space, the bladder is repeatedly inflated and deflated to massage the heart and provide blood flow.

US Classification:

Abstract:

A resilient tubular graft is delivered into place within a body passage by elongating the graft to reduce its diameter and then directing the graft to the desired position while in the elongated condition. The graft is carried into position by a pair of elongate members mounted for longitudinal movement relative to one other. Flexible lines secure opposite ends of the graft to the respective elongate members whereby relative longitudinal movement of the members functions to elongate the graft and reduce its diameter. The lines extend around the graft to impart radial compression thereto simultaneously with elongation of the graft. Upon placement of the graft at the desired location within a body passage, the lines are released to permit the graft to expand into engagement with the passage. Barbs on the graft provide for secure engagement of the graft with a body passage.

International Classification:

US Classification:

606108

Abstract:

The present invention comprises a tubular shunt for insertion into a fluid vessel in a living creature constructed of an elastically deformable material that reduces in circumference when stretched longitudinally so that the ends of the shunt may be easily inserted into openings in a blood vessel and where the material expands circumferentially when allowed to axially contract such that the ends of shunt press against the vessel wall to secure the shunt and form a water tight seal to permit fluid to flow through the tubular conduit of the shunt. A method for shunting fluid-flow in a portion of a vessel in a living creature is also disclosed wherein a shunt of the present invention is stretched longitudinally so that the ends of the shunt contract and then inserted into a lumen of a blood vessel. Following insertion of the shunt, the shunt is allowed to return to its relaxed geometry so that it forms a fluid tight seal with the interior of the lumen.

International Classification:

US Classification:

623 135, 623 127

Abstract:

The present invention provides modular bifurcated intraluminal tubular prostheses, particularly stents and stent-grafts, for the treatment of disease conditions, particularly aneurysms. Modular sections of the prostheses, or âprosthetic modules,â may be selectively assembled to form a prosthesis having characteristics which are tailored to the specific requirements of the patient, including branch angle and branch lumen sizes which match the patients vascular geometry. A Y-connector prosthetic module structure provides support and separation for each of the adjacent branching lumens. Radiopaque markers on the prostheses promote alignment between prosthetic modules and with the body lumen system.

International Classification:

US Classification:

370503, 370465

Abstract:

A network adapter for a synchronous logical ring network operates on existing physical twisted-pair telephone topologies. Information propagates around the logical ring, reaching every device on each revolution around the network. Network devices are full-duplex, transmitting and receiving information on every clock cycle. Network devices arbitrate to be elected the network clock device. By synchronizing all network devices to a single reference clock, and providing fixed frames of information propagating around the network at consistent time intervals, the logical ring network ensures that information propagates from one device to another at consistent time intervals. The fixed-length frames are divided into two independent streams: a data stream for the distribution of real-time continuous digital media streams; and a system command stream for the distribution of system commands.
