摘要： The invention relates to a hand access laparoscopy device having a gelcap, a retainer, a sleeve and a retention ring. The gelcap includes gel that is bonded to a cap. The cap includes an inner cylindrical wall to which the gel in bonded, thereby providing a sealing area between the device and the wound in a body wall. By securing the gel to the inner cylindrical wall, the thickness of the gel and corresponding cap is minimized along with the overall footprint of the device. With the gel thickness reduced and able to be substantially flush, the “doming” phenomenon produced by insufflation of a patient's abdomen is reduced.

摘要： The invention is directed to a trocar adapted to form a seal around a surgical instrument, the trocar comprising a cannula having an axis extending between a proximal end and a distal end; a housing having a proximal wall and forming with the cannula a working channel sized and configured to receive the instrument; a septum seal disposed in the housing and extending transverse to the axis of the cannula across the working channel, the septum seal having a normal state when the instrument is absent from the working channel and a stretched state when the instrument is being withdrawn from the working channel; portions of the proximal wall of the housing defining an orifice sized and configured to receive the instrument into the working channel; and an elastomeric ring-shaped projection extending axially distally between the proximal wall and the septum seal, the ring-shaped projection having an axial length adapted to deform to prevent inversion and binding of the septum seal and the orifice upon withdrawal of the surgical instrument. In particular, the septum seal is prevented from reaching the orifice in the proximal wall of the housing when the instrument is withdrawn. The projection may be bonded, insert-molded, or compressively fitted to the proximal wall of the housing. The projection may be formed of an elastomeric material such as natural or synthetic rubber. The projection may further comprise a plurality of portions or fingers extending axially distally from the proximal wall, each of the extending portions or fingers may further include a living hinge. In another aspect, the ring-shaped projection may be formed on the surface of the septum seal instead of the proximal wall of the housing. That is, the ring-shaped projection may be formed to extend axially proximally from the surface of the septum seal toward the proximal wall of the housing.

摘要： An insufflating surgical instrument adapted for movement across an abdominal wall to insufflate an abdominal region of a patient is disclosed comprising a shaft having an insufflation channel extending along an axis between a proximal end and a distal end, the insufflation channel being adapted for connection to a source of fluid under pressure at the proximal end, a tip at the distal end of the shaft, and at least one vent hole formed at the tip or the shaft being in connection with the insufflation channel and being adapted to expel the fluid under pressure to insufflate the abdominal region. At least one of the tip and the shaft is formed of a translucent or transparent material such as polycarbonate to facilitate visualization of the abdominal wall and the abdominal region. The shaft includes a lumen extending along the axis between the proximal end and the distal end to enable insertion of a laparoscope. The lumen and insufflation channel may be formed as separate channels or as one shared channel. The tip may be blunt, the shaft and the tip may be integrally formed, and the vent hole may be of any geometric shape including round, oval, square and rectangular. The blunt tip may further comprise a marker to indicate penetration of the abdominal wall. In another aspect, the tip may be sharp, pointed or bladed to facilitate penetration of body tissue.

摘要： The invention primarily is directed to a medical tubing adapted for insertion into a body tissue or cavity and method of manufacturing different variations of the tubing along a length of the tubing. The tubing comprises a plurality of individual, discrete, generally ring-shaped elements arranged in series and fused or bonded together forming a continuous tubular structure. The ring-shaped elements may be formed of a thermoplastic or a thermoset material. The ring-shaped elements may include plastic rings, metallic rings, un-reinforced plastic rings and/or metal reinforced plastic rings assembled along the length of the tubular structure to provide variable flexibility and kink-resistance. The tubular structure may have a cross-section of any geometric shape and it may be bent, twisted or curved without kinking. The ring-shaped elements may have different flexural modulus. The ring-shaped elements may include a combination of flexible and rigid ring-shaped elements assembled along different portions or sections of the tubular structure. The ring-shaped elements may be metallic and may be bonded with a resilient, flexible elastomeric adhesive, wherein the ring-shaped elements may have different lengths and may be fused closer or further apart to one another depending on the characteristics of a portion or section of the tubing. In another aspect of the invention, the medical tubing may further comprise a secondary lumen and a pull wire to control the tubular structure. The ring-shaped elements may be truncated to provide a bending bias. In another aspect of the invention, the ring-shaped elements may vary in diameter and/or composition in different portions or sections of the tubular structure. In yet another aspect of the invention, some of the ring-shaped elements may be radiopaque, or the ring-shaped elements may comprise of different colors to operate as indicators along the tubular structure.

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.

摘要： A surgical access valve is adapted to introduce an instrument into a body cavity or conduit. The valve includes a valve housing and a seal material disposed in the housing. Portions of the seal material define an instrument channel that is normally closed to inhibit fluid communication through the seal material. A dilator is moveable distally to open at least a portion of the instrument channel thereby facilitating passage of the instrument through the seal material, and is also moveable proximally to facilitate formation of a seal around the instrument. The dilator can be biased to a distal position and detented in a proximal position to facilitate one single-handed operation of the valve.
