    Abstract: The invention is directed to open-channel extrusions of plastic materials. In one aspect, an open-channel tubing is formed by extruding a first plastic material forming an elongate tube having the open channel; and extruding a second plastic material filling the open channel such that the second plastic material forms a weak bond with the first plastic material, and the weak bond is then selectively broken or dissolved to yield the open channel in the first plastic material. The first and second plastic materials are different from one another and each comprises at least one of polyester, polyethylene, nylon, polyurethane, HDPE, plastic elastomers (TPE) and Kraton. The first and second plastic materials are preferably extruded at about the same time. In another aspect, at least one of the first and second plastic materials may be doped with an additive to form the weak bond. The process of the invention may further comprise the step of mechanically stripping or removing the second plastic material from the first plastic material, chemically dissolving the second plastic material using a chemical solvent, or separating the second plastic material in a thermal melting process. Mechanically stripping the second plastic material may further comprise pressuring or evacuating the extruded elongate tube. To chemically dissolve the second plastic material, the first plastic material may include an aramid plastic, the second plastic material may include a styrene plastic, and the chemical solvent may be acetone or MEK.

    Abstract: 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 bladed. 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 to 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 port 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 port. The distal tip may be formed from a clear material to allow viewing through an endoscope during placement of the surgical access port.

    Abstract: The invention is directed to a suture clinch that may be placed upon suture extensions of a placed suture to securely lock the extensions in a desired location. The clinch operates to replace a tied knot and retain the suture in a fixed relationship with little or no damage to the suture itself. The clinch comprises a mating pair of interlocking members that restrict movements of the suture. The interlocking members may be placed upon the suture extensions from alongside the suture extensions and compressed to a first condition where the interlocking members may be advanced, retracted or adjusted, and subsequently further compressed to a second condition where the interlocking members are fully engaged to fully restrict the movement of the suture. In another aspect, the clinch may be provided in a flat form comprising a first component and a second component. The first and second components fit together in a mating relationship that entraps at least a portion of the suture between tractive faces of the first and second components, respectively. Each end of the first and second components may have a recessed central portion that leaves two extensions along the sides of each end of the components. The extensions of the second component are subsequently folded over the first component to provide secure entrapment of the suture between the tractive faces of the first and second components. The tractive faces operate to engage the suture and hold it securely in place without damaging or challenging the suture. The clinch may comprise of plastic, metallic materials such as stainless steel or titanium, or a combination of both where the plastic is chosen for its value as an atraumatic interface and the metal for its radiopacity or durability.
