    摘要： A seal assembly for a fluid pressure control device includes a guide element having a scaling surface and a first guide surface. A throttling element assembly includes a throttling element positionable within a fluid flow path, the assembly defines a mating surface adapted to seal with the sealing surface, and a second guide surface sized to slidingly engage the first guide surface. A relief void is formed in at least one of the guide element and the throttling element assembly adjacent the first and second guide surfaces to receive loose solid material, to thereby prevent disruption of the seal formed between the sealing surface and the mating surface.

    摘要： Catheters, assemblies, and methods for delivering and recovering embolic protection devices. Catheters are provided that can be advanced over single length guide wires and which can be retracted over single length wire shafts of distal embolic protection devices. One catheter is a two-port catheter having two sidewall ports, a distal end port, and a proximal end port. The two-port catheter can be advanced over a guide wire threaded between the distal end port and the distal sidewall port. An embolic protection device wire shaft can be back loaded into the distal end port and out the proximal sidewall port. A three-port catheter includes a distal end port, and distal, intermediate, and proximal sidewall ports. The distal sidewall port can be dimensioned to accept passage of a filter body through the port. The distal end port can be dimensioned to accept only a guide wire to provide a smooth transition from the guide wire to the small profile distal end. The guide wire can extend between the distal end port and the intermediate port while the filter body shaft can extend through the proximal port, to be distally urged through the distal sidewall port. Another catheter embodiment is a slotted catheter, including a biased, normally open slot over most of its length. The slot can be sufficiently small to resist unwanted transverse movement of a wire through the slot. The slotted catheter can be retracted over a wire by forcing the wire through the resilient slot.

    摘要： Systems and methods for controllably traversing a tissue wall. In one embodiment, a distal end of a catheter is positioned and/or repositioned utilizing direct visualization out the distal end of the catheter, as facilitated by an imaging element disposed within the distal tip of the catheter. An inflatable balloon may comprise a portion of the distal tip of the catheter for structural and/or visualization media purposes. A tissue traversing element may be forwarded through a working lumen defined by the catheter and controllably pushed through a tissue wall as observed with the imaging element. The tissue traversing element may comprise sensors and the like to facilitate monitoring of changes in pressure, color, oxygen saturation, flow rate, and echo timing, to determine the position of the tissue traversing member relative to the tissue wall.

    摘要： An instrument for engaging a bone anchor may include a first implant engaging member having a proximal end and a distal end and a second implant engaging member having a proximal end and a distal end. The second implant engaging member may be integrally connected to the first implant engaging member by a pair of opposed integral spring members located proximal to the distal ends of the first and second implant engaging members. Manipulation of the proximal ends of the first and second implant engaging member can cause each of the distal ends to rotate about the pair of opposed spring members to engage at least a portion of a bone anchor. A rod adjusting tool may be connectable to the bone anchor engaging tool and may be axially adjustable relative to the bone anchor tool to adjust a spinal rod relative to the bone anchor.
