摘要： A drainage catheter is adapted to drain fluid from the body cavity through a body conduit and includes an elongate tube and a retention member disposed at the distal end of the elongate tube. The retention member is adapted for movement between a low-profile state facilitating insertion of the catheter and a high-profile state facilitating retention of the catheter in its operative position. A woven mesh forms at least a portion of one of the tube and the retention member. 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 a stylet which can be removed after insertion to permit the catheter to automatically return to its high-profile state.

摘要： The trocar system includes a cannula insertable through a body wall using an obturator having a distal tip. A traction tread disposed interiorly of the obturator inverts at the distal tip and extends proximally along the outer surface of the obturator or cannula. At the distal tip the tread can facilitate parting rather than cutting the tissue Along the outer surface, the tread can engage the tissue to pull it proximally along the advancing obturator. This produces counter forces which can result in a net proximal force facilitating distention of the abdominal wall and separation of the abdominal wall from internal organs The traction tread can be axially and/or radially continuous. An associated method of operation includes the steps of contacting the body wall with the traction tread at the distal tip, and engaging the body wall with the traction tread along wall portions facing the outer surface

摘要： The invention is directed to a trocar seal adapted to form a seal around a surgical instrument, the trocar seal comprising a housing having an axis extending between a proximal end and a distal end and forming a working channel sized and configured to receive the surgical instrument; an elastomeric septum seal having a proximal face and a distal face, the septum seal being disposed in the housing and extending transverse to the axis of the housing across the working channel; portions of the septum seal defining a hole having a diameter less than or equal to the diameter of the surgical instrument so that during insertion of the instrument along the working channel the septum seal forms a seal with the instrument; and at least one structure formed integrally with or proximate to the septum seal to prevent inversion of the septum seal upon withdrawal of the surgical instrument. The septum seal or the housing may further comprise a sidewall to include the structure extending from the sidewall to the distal face of the seal to tether the seal distally. The structure may be integrally formed with the proximal face of the septum seal to reinforce the seal, or the structure may be integrally formed with the distal face of the septum seal to tether the seal distally The structure may be an annular reinforcement or rib, and is formed so as to allow side-to-side movement or floatation of the seal. The trocar seal may further comprise a plurality of radially extending ribs formed on the proximal or distal face of the septum seal to reinforce the seal. The trocar seal may further comprise a tensile element formed on the distal face of the septum seal.

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： An insufflation gas warmer and humidifier apparatus and methods are provided. Insufflation gas is received from a bulky insufflation tubing. Insufflation gas received travels through, in one aspect, a channel or winding flow path, in a passage. The configuration of the passage ensures that the insufflation gas, which travels through the passage, receives sufficient heat and moisture. A humidifying reservoir humidifies the insufflation gas as the insufflation gas is passed to the passage. In one aspect, an oxygenator introduces slight amounts of oxygen into the insufflation gas. A warmer connected to the passage warms the gas in the passage. The warmer, in one aspect, contains a reactive agent that when exposed to air produces heat that is transferred to the passage to warm the insulation gas within the passage.

摘要： A surgical staple-clip including a clip component and a securing member is used in a wide range of surgical procedures. The staple-clip may be introduced to a surgical site in an un-assembled condition through a small port or trocar. An applier for the staple-clip comprising a pair of opposed jaw-like channels is provided to position and apply the clip component and the securing member. The clip component is positioned around a target tissue and is compressed or clamped upon the tissue using only the force required for a specific surgical procedure such as occlusion, ligation or fixation. When the clip component is properly applied, the securing member is urged forward and over the clip component to secure the staple-clip. The clip component may include traction enhancement features such as surface interruptions, bumps, valleys and ridges. With the staple-clip of the invention, the force required to constrict or occlude the tissue is separate from the force required to secure and maintain the staple-clip in position and, as a result, the body tissue is not over-compressed and nourishment to the body tissue is maintained. Other aspects of the invention include thumb actuated clip appliers for use in hand assisted laparoscopy (HAL). In one embodiment, a clip applier includes a handle and a thumb actuated mechanism that is used to slidably release clips onto a body tissue or vessel by sliding the thumb actuated mechanism forward and backward using only one hand. In another aspect of the invention, a two-stage clip is disclosed having a clip component and a staple component for securing the clip after it has been properly positioned.

摘要： An improved clip or clamp is provided having a one-piece wire-form construction that is suited for rapid and repeatable manufacture. The clamp, which may be disposable or reusable, includes a first jaw portion, a second jaw portion, a first handle portion, a second handle portion and a central coil or tensioning device, all of which are formed from a single piece of wire. The central coil or tensioning device comprises one or more turns. The handle portions may include ring-shaped distal ends that further enhance grip. The jaw portions may be shaped, curved, bent or otherwise configured to provide access to specific areas of a procedure. The clamp may be coated with a material providing improved traction and padding. In a method of the invention, a single wire is wound at least one turn forming the central coil and two extensions. A first extension of the wire is formed into the first jaw portion by bending back on itself, the first extension is then returned to the central coil where it is formed to rest upon an outer surface of the central coil. The bent first extension, which now extends rearward in a direction opposite to the direction of the first jaw portion, is then bent again forming the first handle portion. A second extension is similarly bent to form the second jaw portion and the second handle portion. The single-wire construction of the clamp may be achieved through programmed wire forming. In another aspect of the invention, a plurality of clamps may be placed upon a traction rod made from a metal or plastic material to align two or more stump portions of a severed vessel or tissue for reconnection or anastomosis.
