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.

摘要： A suture system for closing a wound defined by tissue portions includes an elongate suture having a pair of ends adapted for threading relative to the tissue portions leaving the suture ends free. A securing mechanism has a first position for capturing the suture ends and a second position for permanently holding the suture ends in a fixed relationship, with the suture tensioned to maintain the tissue portions in close proximity. In a third position, the securing mechanism frictionally engages the suture ends in a sliding relationship. In an associated method, continuous tension is placed on the suture ends during operation of the securing mechanism.

摘要： An electrosurgical system can include an electrosurgical generator, a feedback circuit or controller, and an electrosurgical tool. The feedback circuit can provide an electrosurgery endpoint by determining the phase end point of a tissue to be treated. The electrosurgical system can include more than one electrosurgical tool for different electrosurgical operations and can include a variety of user interface features and audio/visual performance indicators. The electrosurgical system can also power conventional bipolar electrosurgical tools and direct current surgical appliances.

摘要： A surgical access device, such as a trocar, includes a pendent valve having an elongate structure extending from a proximal end to a septum valve disposed at a distal end. In operation, the elongate structure follows the angle of the instrument to pre-position the septum valve into the path of the instrument where it is not significantly challenged during instrument insertion or manipulation. The pendant valve can be made to float at both the proximal end and the distal end of the elongate structure, to further reduce the vulnerability of the septum valve. Since the valve is less vulnerable to instrument insertion, it can be formed to minimize friction and maximize the functional range of the access device.
摘要翻译：手术进入装置，例如套管针，包括具有从近端延伸到设置在远端的隔膜阀的细长结构的侧悬阀。在操作中，细长结构遵循仪器的角度，以将隔膜阀预先定位到仪器的路径中，在仪器插入或操纵期间，隔膜阀不会受到严重的挑战。悬挂阀可以制成在细长结构的近端和远端两侧浮动，以进一步降低隔膜阀的脆弱性。由于阀门不易受仪器插入的影响，因此可以形成最小化摩擦力并最大化进入设备的功能范围。

摘要： A multi-seal trocar system includes a plurality of co-axial sealing elements adapted for forming a seal with either a large or small instrument. Small and large sealing elements are disposed in an in-line arrangement such that a-single port is provided for instrument insertion. A zero seal is disposed distally of the sealing elements to seal a working channel of the system and to prevent backflow when no instruments are inserted. The small sealing element is configured such that insertion of a large instrument automatically moves the small sealing element out of its path, thereby avoiding contact with the large instrument.

摘要： A steerable kink resistant access device is provided having an elongated body and a steerable portion; methods for manufacturing the kink resistant device are also provided. The access sheath has an outside diameter sufficiently small so that it may be inserted into a body cavity or conduit. The access sheath typically has two internal lumen, a first lumen sized and configured as an access to a surgical site and a second lumen sized and configured to contain a tensioning device that, when acted upon, will deflect the steerable portion. The tensioning device may be directly or remotely attached to an actuation device that operates to control the tensioning and loosening of the tensioning device.
