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： 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： 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 insufflation gas within the passage.

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 surgical wound retractor is adapted to dilate a wound stretchable to a desired diameter, the retractor includes a first ring having a diameter greater than that desired for the wound and being adapted for disposition interiorly of the wound. A second ring has a diameter greater than that desired for the wound and is adapted for disposition exteriorly of the wound. A plurality of retraction elements are disposed in a generally cylindrical relationship to each other, between the first ring and the second ring. These elements extend through the wound to exert a radial retraction force on the wound which is dependent on the distance separating the first ring and the second ring. Retraction elements, both distensible and non-distensible are contemplated with appropriate attachment means at the rings to provide for variations in the retraction force. With a suitable retraction sleeve, a third ring can be provided to form a circumferential retainer to vary the retraction force. Rings can also be made inflatable or self-expanding to vary the retraction force. An associated method includes the step of rolling the second ring circumferentially of the third ring to form the circumferential retainer.

摘要： A tamponade trocar includes an elongate balloon having a closed distal end and is adapted to expand from a small diameter to a large diameter. A cannula is positioned at a proximal portion within the balloon lumen. A rigid stylet is removably positioned within the balloon and cannula lumens. A distal end of the stylet supported balloon is inserted into a perforation in a body wall and advanced into a body cavity while the balloon is unexpanded. The balloon is expanded and the cannula is advanced to a distal portion of the balloon lumen and across the body wall. At this stage, the perforation is dilated and in compressive tamponade. The proximal portion of the balloon may be removed and a seal housing may be coupled to the proximal end of the cannula. The distal end of the balloon may be punctured and opened, making the trocar ready for use.

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 100 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： A steerable kink resistant access device is provided having an elongated body and a steerable portion. 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.
