    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normal state when the instrument is absent from the working channel and a stretched state when the instrument is being withdrawn from the working channel; portions of the proximal wall of the housing defining an orifice sized and configured to receive the instrument into the working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the septum seal is prevented from reaching the orifice in the proximal wall of the housing when the instrument is withdrawn.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： 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： An incrementally adjustable wound retractor, which provides access to a body cavity, includes an inner ring having a diameter greater than the desired diameter of the wound incision, an outer ring having an annular axis and a diameter greater than the desired diameter of the wound incision, and a flexible sleeve disposed in a generally cylindrical form between the inner and outer rings. The outer ring includes first and second circular tubes spaced apart axially with each including a lumen having a rigid, noncompliant split hoop placed therein. The outer ring may be rolled over itself and around the annular axis to retract the sleeve with sufficient force to stretch the incision to the desired diameter. A gel cap seal may be coupled to the outer ring outside of the biological body to seal the opening produced by the wound retractor between the body cavity and outside the body cavity.

    摘要： A trocar fixation device includes a cannula and an elongate tube mounted onto and coupled to the exterior surface of the cannula with the distal end of the cannula extending distally beyond the distal end of the elongate tube. The elongate tube includes a plurality of slits cut at an angle to a longitudinal axis of the elongate tube. The trocar fixation device is activated by rotating the proximal-end region of the elongate tube in a first direction and is deactivated by rotating the proximal-end region of the elongate tube in a second direction, opposite to the first direction. Activation of the trocar fixation device compresses the material positioned between adjacent slits and forces the material radially outwardly, away from the exterior surface of the cannula, thereby forming ridges. Deactivation of the trocar fixation device returns the exterior surface of the elongate tube to a substantially smooth condition.
