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: A surgical atherectomy apparatus for removing particles such as plaque from an interior of a vessel having a motor housing slidable axially between a proximal position and a distal position. An axially fixed sheath extends from the outer housing and a catheter is connected to the motor housing and is positioned within the sheath. A rotatable shaft is positioned within the lumen of the catheter and is operatively connected to the motor for rotational movement, the rotatable shaft and catheter movable by movement of the motor housing between the proximal and distal positions. The rotatable shaft has an atherectomy bit extending therefrom for dislodgement of particles when rotated by the motor and dislodged particles are aspirated in the lumen of the catheter.

Abstract: A helmet including a body, an outer shell having an inner surface and an outer surface and a plurality of shock absorbers, the shock absorbers being positioned internal of the outer shell. A first set of shock absorbers has a first shock absorption characteristic and a second set of shock absorbers has a second shock absorption characteristic, the second shock absorption characteristic being different than the first shock absorber.

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 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 having a dimension to prevent egress of fluid through the aperture and having a first opening. A first retainer is positionable external of the vessel. A flexible connecting member operatively connects the covering member and the first retainer, wherein the first opening of the covering member is configured to restrict movement of the connecting member.

The intermediate looped portion is adjustable to loops of different diameters dependent on an inner diameter of the vessel wall.

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.
