摘要:
A tissue sample needle actuator system and apparatus includes an actuation mechanism for, among other things, automatically thrusting a tissue sample needle forward and/or automatically rotating an inner tube of the tissue sample needle relative to an outer tube of the tissue sample needle to operate an integral snare. The actuation mechanism may perform other functions such as, for example, rotating the entire needle (e.g., during thrusting, during operation of the snare, or during a separate phase), which may, in some situations, facilitate insertion of the needle and/or obtaining a tissue sample. The actuator may also support a stylet for facilitating insertion of the needle and/or ejection of the tissue sample.

A binding system is provided that is effective for use on recreational device, such as a snowboard, and that is adapted to mate to, or that includes, a boot or other footwear worn by the user. In general, the binding system includes a base plate for support a rider's foot, and a connecting element for mating the base plate to an elongate board, e.g., a snowboard. The connecting element is effective to mate the base plate to a snowboard about a fixed central axis and to allow pivotal movement of the base plate about the central axis with respect to the snowboard. The binding system can also include at least one compression member mated to the base plate and/or to a snowboard. The compression member(s) are effective to compress between the base plate and the snowboard in response to a force applied to at least one of the base plate and the snowboard. The binding system is particularly advantageous in that the compression members provide enhanced biomechanical operation, absorbing chatter and shock, and increasing mobility. Moreover, there is no relative motion between the base plate and the boot, so the rider's ability to control the snowboard is not adversely affected.

Devices and methods are provided for extracting and macerating tissue, and optionally for depositing the tissue onto a tissue scaffold. The device generally includes an outer tube having a substantially open distal end that is adapted to be placed on and preferably to form a seal with a tissue surface, and a shaft rotatably disposed within the outer tube and movable between a first, proximal position in which the shaft is fully disposed within the outer tube, and a second, distal position in which a portion of a distal end of the shaft extends through the opening in the distal end of the outer tube. The device also includes a tissue harvesting tip formed on the distal end of the shaft that is effective to excise a tissue sample when the shaft is moved to the distal position, and a cutting member that is coupled to the shaft at a position proximal to the tissue harvesting tip. The cutting member is effective to macerate a tissue sample excised by the tissue harvesting tip.
摘要:
A footwear sole structure for dynamically directing interacting forces between a user's foot and the footwear during a stride, including an inner sole located adjacent the user's foot, a mid-sole located between the inner sole and the footwear, and a rib ribbon force transfer structure located between the inner sole and the mid-sole wherein the rib ribbon includes a plurality of ribs spaced along and transversely to a spine axis and attached to a longitudinally extending spine. The rib ribbon resists flexing about an axis parallel to the spine axis and allows a relatively greater degree of flexing about an axis transverse to the spine axis and the rib ribbon is located along a path between the inner and mid-soles to dynamically direct the interacting forces between a user's foot and the footwear as the user's weight shifts from a heel to a toe position during a stride.
摘要:
A small diameter delivery device capable of delivering a tissue loaded scaffold arthroscopically to a tissue defect or injury site without reducing the pressure at the injury site is provided. The scaffold delivery device of the present invention comprises a plunger system that includes two main components: an insertion tube and an insertion rod. The insertion tube has a flared proximal end for holding a tissue scaffold prior to delivery. An elongate, hollow body extends from the flared proximal end to a distal end of the insertion tube, and defines a passageway that extends through the body for delivery of the tissue scaffold. The insertion rod has an elongate body that extends into a handle at a proximal end and a tip at a distal end. The insertion rod is configured to be removably disposed within the insertion tube for sliding along the passageway to effect delivery of the tissue scaffold through the insertion tube.
