摘要： A fluid controlled device (10) is adapted for disposition in a body conduit where it controls the flow of body fluids within the conduit. A sleeve (60) is provided with a wall of separation having a first surface which defines a flow passage facilitating the flow of body fluids, and a second surface which defines an exclusion chamber sealed from the flow passage. Various dilators (46, 48) have properties for moving the seal between a low profile state facilitating insertion of the device, any high profile state defining the flow passage and exclusion chamber (67). The dilators (46, 48) may be skeletal, inflatable or porous. An associated method includes the step of dilating a dilation assembly to move a wall from a low profile, insertible state to a high profile wherein the wall defines a flow passage and an exclusion cavity.

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 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 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 Nave 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 Nave 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 tissue welding apparatus is adapted to fuse a first piece of tissue to a second piece of tissue which are disposed in a surface proximate relationship. An elongate shaft carries a first jaw, and a second opposing jaw moveable relative to the first jaw. At least one penetrating member is carried by the first jaw and moveable relative to the second jaw to create a channel through the first piece of material and the second piece of material. A source of heat is coupled to the penetrating member for denaturing the tissue defining the channel. This denatured tissue forms a column binding the first piece of tissue to the second piece of tissue. A chemical agent can be carried to the tissue with the penetrating member.

摘要： The present invention relates to a surgical access port for insertion into a body cavity having an elongate tubular body extending along an axis between a proximal end and a distal end, and a tip disposed at the distal end of the tubular body for penetrating through a body wall and into the body cavity. The distal tip operates to move from a first, penetrating position to a second, retaining position when the body wall has been traversed. The surgical access port may further comprise a seal housing operably connected to the proximal end of the tubular body, the seal housing having an access port providing an opening into the tubular body to allow passage of surgical instruments. The distal tip may be sharp, pointed or faded. The distal tip may also be substantially blunt or have a conical surface. The access port may further comprise a retention member for connecting the tubular body and the distal tip. The retention member may be biased t~ hold the distal tip in an off-axis position when there is no axial load, or it may be lightly held in axial alignment and subsequently deflected in the presence of an instrument within the tubular body. The distal tip, which may comprise one or more parts or petals, may reposition to the side of the tubular body in a substantially right-angled condition in the second, retaining position. The repositioned tip remains in an off-axis condition until removal of the access port, at which time the distal tip automatically realigns with the axis of the tubular body as the access @>rt is withdrawn from the body wall. The tubular body may be a thin walled tube. The distal tip may comprise a conical, tapered or rounded shape to separate tissue layers. The distal tip may be solid or hollow, which may act as a specimen bag by closing on a specimen and pulled inside the tip during removal of the access @>rt. The distal tip may be formed from a clear material to allow viewing through an endoscope during placement of the surgical access @>rt.
