摘要： A stent is adapted for disposition in a body conduit of a patient and comprises a mesh formed in the configuration of a tube and having an axis and axial convolutions, which facilitate movement between a low-profile state and a high-profile state. The tube in the low-profile state has an elongate configuration and a wall with a first thickness and first tube strength. The tube in the high-profile state has a compressed configuration and a wall with a second thickness greater than the first thickness and a second hoop strength greater than the first hoop strength. An associated method of use includes the steps of mounting the step on a catheter between first and second enlargement members, increasing the size of the enlargement members, and moving the enlargement members to axially compress the stent to the high-profile state. An associated method of manufacture includes the steps of corrugating the mesh on a mandrel by moving the ends of the mesh toward each other. The mesh can then be heat-set in the high-profile state.

摘要： A duckbill check valve and septum combination includes a hollow elastomeric body having an open proximal end, a closed distal end and a pair of opposed flat portions that form a distal edge. The distal edge includes a slit having a periphery that is smaller than the periphery of the instrument inserted therethrough. The slit provides a zero seal in the absence of an instrument and an instrument seal in the presence of an instrument. A shield including a tubular member and a plurality of blades protruding distally from the distal end of the tubular member may be placed inside the check valve and operates to center and guide the surgical instrument through the blades before expanding the slit of the check valve. An instrument inserted into the check valve stretches the distal portion of the duckbill valve to form a septum-like seal around the inserted instrument.

摘要： The present invention relates to a surgical access device comprising an elongate tubular member having a working channel and an axis extending between a proximal end and a distal end, a septum seal integrally formed at the distal end of the tubular member, and a zero seal disposed at the distal end of the tubular member and distal to the septum seal, the zero seal being sized and configured to seal when no instrument is in place within the working channel of the tubular member, and the zero seal being coupled to the septum seal and having properties to float with the septum seal relative to the tubular member. The tubular member may be formed from an elastomeric material. The tubular member has a wall that may be rigid or semi-rigid, and the tubular member may be reinforced with a coil along a portion of the tubular member. The tubular member may include a distal, mechanically deployable shielding portion. The zero seal may be a duckbill seal constructed with one or more intersecting sealing portions. The duckbill seal may comprise of opposing lip portions separated by a slit portion. The opposing lip portions are coated with or attached to a soft or occlusive material. The occlusive material is one of Kraton, polyurethane or the like. The occlusive lip portions allow a surgical item such as a suture to extend through the slit portion without disrupting the seal. In one aspect, the tubular member and the septum seal are molded together as a single unit and the zero seal is then bonded or fused to the septum seal. In another aspect, the tubular member, the septum seal and the zero seal are all molded together or integrally formed as a single unit. The tubular member may further comprise flexibility enhancing features to allow the tubular member to flex in response to a motion of a surgical instrument within the working channel of the tubular member.

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 trocar system for providing access across a body wall includes a trocar and an anchor provided in the form of a first helix. The anchor is adapted for placement in an operative position wherein the anchor extends at least partially through the body wall. A second helix formed on the trocar is size and configured to engage the first helix of the anchor so that rotation of the trocar relative to the anchor moves the second helix along the first helix. In this manner, the trocar is drawn into the anchor as it moves into the body wall. A proximal force applied to the anchor resists tenting of the abdominal wall. The anchor also holds the layers of the body wall together thereby resisting peritoneal separation.

摘要： A laparoscopic insufflation device is provided in the configuration of a coil with a blunt tip. The device is capable of passing through the abdominal wall without cutting tissue, and exiting the abdominal wall substantially parallel to the inner surface. While rotation of the coiled device results in forward movement through the abdominal wall, a counter force can be applied to the device to create a safety space between the wall and the interior organs. With the blunt distal tip, parallel exit angle, and safety space, there is substantially no threat to the interior organs during placement of the device. Further space can be generated with the use of pressured gas to produce an abdominal cavity for the subsequent placement of trocars. By rotatably attaching the coiled insufflation device to a trocar, the advantage of a counter force can be used not only to establish the safety space but also to pull the trocar into the abdominal wall with a counterforce which resists tenting.

摘要： The invention is directed to a bladeless trocar obturator to separate or divaricate body tissue during insertion through a body wall. In one aspect, the obturator of the invention comprises a shaft extending along an axis between a proximal end and a distal end; and a bladeless tip disposed at the distal end of the shaft and having a generally tapered configuration with an outer surface, the outer surface extending distally to a blunt point with a pair of side sections having a common shape and being separated by at least one intermediate section, wherein each of the side sections extends from the blunt point radially outwardly with progressive positions proximally along the axis, and the shaft is sized and configured to receive an optical instrument having a distal end to receive an image of the body tissue. With this aspect, the tapered configuration facilitates separation of different layers of the body tissue and provides proper alignment of the tip between the layers. The side sections include a distal portion and a proximal portion, the distal portion of the side sections being twisted radially with respect to the proximal portion of the side sections. The intermediate section includes a distal portion and a proximal portion, the distal portion of the intermediate section being twisted in a first radial direction and the proximal portion of the intermediate section being twisted in a second radial direction opposite the first radial direction.

摘要： A trocar is provided with a cannula and a housing and valve assembly disposed in the housing which forms a housing seal, and instrument seal, and in some cases a zero seal. A gel material is included in the valve and provides the valve with superior flotation properties for maintaining the instrument seal even when the instrument is moved off-axis. In order to accommodate movement of the gel material, voids can be formed within the valve housing and even within the gel material
