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： 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 surgical access device is adapted to facilitate access through an incision in a body wall having an inner surface and an outer surface, and into a body cavity of a patient. The device includes first and second retention members adapted to be disposed in proximity to the outer surface and the inner surface of the body wall, respectively. A membrane extending between the two retention members forms a throat which is adapted to extend through the incision and form a first funnel extending from the first retention member into the throat, and a second funnel extending from the second retention member into the throat. The throat of the membrane has characteristics for forming an instrument seal in the presence of an instrument and a zero seal in the absence of an instrument. The first retention member may include a ring with either a fixed or variable diameter. The ring can be formed in first and second sections, each having two ends. Couplings can be disposed between the ends to accommodate variations in the size of the first retention member. The first retention member can also be formed as an inflatable toroid, a self-expanding foam, or a circumferential spring. A plurality of inflatable chambers can also provide the surgical access device with a working channel adapted for disposition across the body wall. A first retention member with a plurality of retention stations functions with a plurality of tethers connected to the membrane to change the shape of the membrane and the working channel. A stabilizing platform can be used to support the access device generally independent of any movement of the body wall.

摘要： A positionable internal retraction device is provided comprising a malleable ring member and a web-like structure. The retraction device operates to temporarily reposition tissues and organs from an operative site to provide a clear access and visual path for the surgeon. The ring member may be elongated, twisted, folded, bent or deformed to provide an appropriate insertion profile and subsequent functional shape. The retraction device may be shaped for both open and minimally invasive surgeries. The retraction device is atraumatic and may be used for retraction of delicate tissues and organs. The ring member may have different bending biases. The web-like structure may be constructed of any elastic material that can stretch and recover from the shaping and reshaping of the ring member. In another aspect of the invention, the ring member further comprises an internal lumen defining a wall, which may be of any geometric shape providing a desired bending bias. The ring member may further include a reinforcement member placed within the lumen and made of a “shape memory” material that allows the reinforcement member to return to its desired shape or condition after being bent. The reinforcement member may be placed in some sections of the ring member to keep these sections substantially straight. Each of the ring member, the reinforcement member and the internal wall may have a cross-section or profile of any geometric shape to provide a desired bending bias in a preferred plane. In yet another aspect of the invention, the ring member further comprises a second lumen and a second reinforcement member placed within the second lumen to provide a desired bending bias.

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： The invention is directed to nanostructure surface treatments, coatings or modifications formed from nanoscale building blocks. The nanostructure surface treatments, modifications or coatings have hydrophobic, hydrophilic and surface adherence properties. The nanoscale building blocks have orientation, geometry, packing density and composition that may be adjusted to control the unique surface characteristics of the desired treatment, coating or modification. Applications of this nanostructure technology include surgical clips, staples, retractors, sutures and manipulators where an improvement in traction, retention or occlusion is desired without excessive material or tissue deformation or where high compressive forces would be undesirable, dangerous or ineffective. In one aspect, a nanostructure surface treatment for a medical device having an external surface is disclosed, wherein the treatment is applied on the external surface to provide a hydrophobic or a hydrophilic surface. With this aspect, the treatment comprises titanium dioxide and provides nanoscopic structures having nearly vertical sidewalls. The treated surface of the device has contact angles greater than or equal to 150 degrees. The vertical sidewalls provide a negative capillary effect and have a width of about 200 nm. The vertical sidewalls attach to a wet surface by the negative capillary effect. The van der Waals forces of the vertical sidewalls enable the treated surface to attach to a dry surface. The treatment may be vapor deposited and cured on the device, or the treatment may be laser blasted on the device.
