Abstract: A surgical apparatus for removing deposits from an interior of a vessel including an outer member and a rotatable shaft having a lumen to receive a guidewire. The lumen has a cross-sectional dimension to enable fluid injection between an inner diameter of the shaft and an outer diameter of the guidewire. A tip is mounted to the shaft for rotation about its longitudinal axis and mounted such that the distal opening of the shaft is axially spaced from a distal internal surface of the tip such that fluid injected through the lumen of the shaft contacts the distal internal surface of the tip and is redirected proximally to direct in a proximal direction deposits removed by the rotational movement of the shaft. The tip includes including a guidewire lumen for receiving a guidewire to enable over the wire insertion of the apparatus.

Abstract: A surgical apparatus for delivering fluid to treat renal hypertension including an elongated member having a distal tip and a plurality of openings formed in a sidewall proximal of the distal tip. A plurality of fluid delivery members are movably positioned in the elongated member, each of the fluid delivery members having a lumen and at least one opening communicating with the lumen for delivering fluid extravascularly. An actuator is operatively associated with the fluid delivery members, the actuator actuable to a first position to move the fluid delivery members from a retracted position within the elongated member to a deployed position extending radially with respect to the elongated member. A balloon is expandable radially from the elongated member to seal the renal artery during application of fluid through the fluid delivery members.

Abstract: A helmet for tracking impact including at least one sensor, a processor in communication with the sensor and a storage file in communication with the processor, the at least one sensor measures a force applied to the helmet and sends a signal to the processor indicative of the measured force. The processor receives the signal indicative of the measured force and compares the measured force to a predetermined value, wherein if the measured force exceeds the predetermined value data is sent to the storage file to record the measured force. The helmet can include an alarm system and/or an injury tracking system.

Abstract: An orthopedic brace for preventing injury to a wearer including a body having a series of liquid filled regions, the body having a first more flexible state wherein the liquid filled regions contain a liquid material and a second more rigid state wherein the liquid within the regions is hardened to a second harder state, the body transformable from the first state to the second state upon receiving a force which exceeds a predetermined value. A chemical reaction or an isothermal process can cause the phase change.

Abstract: A thrombectomy apparatus for breaking up thrombus or other obstructive material in a lumen of a vascular graft or vessel. The apparatus includes a wire having a first configuration and a second deployed configuration, the wire having a straighter configuration in the first configuration. The wire is operatively connected to a motor for rotation of the wire to contact and break up the thrombus or other obstructive material. A blocking device at a distal portion of the apparatus is movable between a collapsed configuration and an expanded configuration, and is configured in the expanded configuration to block thrombus dislodged by rotation of the wire.

Abstract: A spinal implant having a smaller transverse cross-sectional dimension in the radially compressed configuration than in a first expanded configuration and a more linear configuration in the second delivery configuration than in the first curved configuration. The implant assumes the radially compressed configuration and second delivery configuration during delivery to the disc space and assumes the first curved configuration and first expanded configuration upon placement within the disc space. The implant further moves towards the radially compressed configuration once implanted in response to a load placed on the implant by the vertebral bodies.

Abstract: A device for closing an aperture in a vessel wall comprising a covering member having a longitudinal axis and positionable inside the vessel against the internal opening of the aperture and a first spherical retainer positionable external of the vessel. The covering member has a dimension to prevent egress of fluid through the aperture.

Abstract: A vessel filter having a first region having a first set of struts forming a mounting portion and a filter portion having a converging region at a first portion to direct particles toward the center of the filter. The mounting portion is flared in the expanded position to have a transverse dimension increasing toward a second portion opposite the first portion. A second set of struts forms a second mounting portion flared in the expanded position. A plurality of spaced apart struts extend between the first and second regions.

Abstract: A device for closing an aperture in a vessel wall, the aperture having an external opening in an external region of the vessel wall and an internal opening in an internal region of the vessel wall. The device includes a covering member positionable inside the vessel against the internal opening of the aperture and having a dimension to prevent egress of fluid through the aperture. A securing member is positionable external of the vessel and has a plurality of pores extending therethrough. A flexible connecting member operatively connects the covering member and securing member and moves the securing member toward the covering member.

Abstract: A spinal implant having a series of sections or units hinged together and a balloon connected to at least some of the sections, the balloon having a curved configuration. The implant has a first delivery configuration and a second curved placement configuration, wherein it has a more linear configuration in the first delivery configuration than in the second curved configuration. The implant assumes the first delivery configuration during delivery to the disc space and maintains the curved configuration after placement within the disc space. The curved configuration can result from filling or expanding the balloon.
