摘要： A suturing apparatus adapted to close an incision and an anterior tissue wall includes an elongate support structure having an axis extending between a proximal end and distal end. A receiver disposed at the distal end is insertable through the incision in a low-profile state and expanded to a high-profile state on the far side of the tissue wall. Needles carried by the support structure are operable to extend through the support wall on either side of the incision and into the expanded receiver. Sutures advanced through the needles are captured by the receiver after the needles are removed and the receiver is returned to its low-profile state. Removal of the suturing apparatus from the incision draws the captured suture ends outwardly through the incision. A novel suture knot can be tied in the four suture ends and moved into proximity with the tissue wall to close the incision.

摘要： A drainage catheter is adapted to drain fluid from the body cavity through a body conduit and includes an elongate tube having a distal end and a retention member disposed at the distal end and adapted for movement between the low-profile state facilitating insertion of the catheter and a high-profile state facilitating the tension of the catheter in its operative position. A woven mesh forms at least a portion of one of the tube and the retention member, and can be made permeable or impermeable in various regions of the catheter. The woven mesh can be formed of filaments heat-settable so that the catheter automatically moves to the high-profile state. Insertion of the catheter can be facilitated using an obturator and a guidewire in an associated method, an obturator facilitating insertion of the catheter can be removed to permit the catheter to automatically return to a normal, high-profile state.

摘要： A catheter includes an introducer and a flow isolator adapted for disposition in a primary conduit to facilitate flow in the primary conduit while inhibiting flow and intersecting secondary conduits. The flow isolator may include a tubular mesh and surrounding balloon structure. Alternatively, a sleeve can be provided with a primary opening and a secondary opening which are sized to inflate the sleeve with the body fluid. Structures for deploying the sleeve between a low-profile state and high-profile state may include expandable fingers, or pneumatic chambers inflatable from an external source. In operation the sleeve can be forced by the body fluid against the intersection with the secondary conduits to achieve isolation. Alternatively, the pneumatic chambers can be inflated to form seals with the primary conduit. A blood filter or snare is contemplated to filter any blood clots which may develop around the flow isolator.

摘要： A catheter adapted to increase the patency of a body conduit includes an elongate tube having an axis extending between a proximal end and a distal end, and a balloon disposed at the distal end of the tube and having properties for being expanded to a high-profile state and for being contracted to a low-profile state. A sleeve disposed over the balloon has a pair of ends disposed on opposing sides of a central section, the ends having a floating relationship relative to the tube with the central section disposed circumferentially of the balloon. An electrode disposed outwardly of the sleeve has properties for being electrosurgically energized to incise materials defining the body conduit when the balloon is in the high-profile state. The electrode can be formed of a plurality of elements stranded to increase the surface area of the electrode. The catheter can be inserted relative to a guide member having a conductor which carries the electrosurgical energy from the proximal end of the tube to the electrode at the distal end of the tube. An associated method includes the step of introducing electrosurgical energy into the conductor of the guide member to energize the electrode of the catheter.
