Abstract: An endovascular prosthesis (10) includes a first end (16) a furcated second end (18), and an anchoring means (20). The first end has a longitudinally extending central lumen (32) and means (40) for laterally supporting the first end. The furcated second end (18) includes at least two branches (64) that extend from an intersection of the furcated second end. Each of the branches (64) includes a longitudinal support means (84) and a branch lumen (78) in fluid communication with the central lumen (32) of the first end (16). The anchoring means (20) secures the first end (18) within a vasculature.

Abstract: An apparatus (10) for delivery of an infusate into a body lumen (12) to perform thrombolysis includes a catheter (24) having an infusion section (40) defined by a plurality of infusion ports (42) for delivering the infusate. The infusion ports (42) are spaced axially apart along the length of the infusion section (40). A sheath (50) coaxially surrounds a portion of the catheter (24). The sheath (50) is axially movable relative to the catheter (24) to selectively uncover at least a portion of the infusion ports (42) and thereby control the amount and distribution of the infusate delivered by the infusion section (40).

The apparatus (600) further includes means (614) for constricting the wire loop (632).

Abstract: An apparatus (10) utilizes microelectricalmechanical systems (MEMS) technology to monitor a condition in a body cavity (28). The apparatus (10) comprises at least one sensor (42) for insertion into the body cavity. The sensor (42) generates a signal in response to a condition inside the body cavity (28). At least one telemetric device (44) is operatively coupled with the sensor (42). The telemetric device (44) is operable to receive the signal from the sensor (42) and to transmit an electromagnetic signal dependent upon the signal. The telemetric device (44) includes at least one coil member (82) extending from the telemetric device. The coil member (82) engages the body cavity (28) to secure the telemetric device (44) in the body cavity.

Abstract: The present invention relates to an apparatus (300) for delivering an endovascular prosthesis within a blood vessel. The apparatus (300) includes a sheath (302) having a first end (310), a second end (308), an inner lumen (316) for receiving an endovascular prosthesis, and an outer lumen (322) for receiving a guide wire. The inner lumen (316) extends along a central axis (313) between the first end (310) and the second end (308). The outer lumen (322) is radially spaced from the inner lumen (316) and extends along an outer axis (323) between the ends (308 and 310).

Abstract: A valvulotome for rendering venous valve leaflets incompetent includes a rigid support comprising a fluid supply tube and, molded thereon, a dilator, and first and second valve disrupting heads. Each of the disrupting heads has a plane of symmetry, wherein the planes of symmetry of the two disrupting heads are relatively rotated by about 90.degree.. A fluid emitting end of the fluid supply tube communicates with an irrigation port in a disrupting head so that fluid emitted through the irrigation port, during use, applies pressure to the valve leaflets to be disrupted. The other end of the fluid supply tube is swaged onto a catheter which in turn is coupled to a fluid supply source for the purpose of supplying fluid to the irrigation port.
