Abstract: A polymeric surgical ligating clip is provided having curved leg members joined by a resilient hinge. A leg member includes a flexible rib protruding from a vessel clamping inner surface and extends longitudinally between the proximal and distal end portions of the leg member. The flexible rib defines a channel extending transversely through the rib along a majority of said length. The flexible rib can collapse and provides better retention of the clip on a vessel. The clip can contain a flexible rib on both legs in an interlocking fashion. Or a plurality of teeth can protrude from a second vessel clamping inner surface of a second leg member. The plurality of teeth can include first and second rows of teeth extending longitudinally on the second leg member, transversely separated from each other on opposite sides of a centerline of the clip.

Abstract: A clip applier may be configured to apply a surgical clip to tissue. The clip applier may include a first jaw member configured to engage a distal portion of a first leg member of the surgical clip, and a second jaw member configured to engage a distal portion of a second leg member of the surgical clip. The clip applier may further include a stabilizing member on the first jaw member. The stabilizing member may have a cavity configured to receive a proximal portion of the surgical clip and to reduce lateral movement of the surgical clip. The clip applier may not proximally abut the surgical clip when the first and second jaw members are in an open configuration. The second jaw member may also have a longitudinal channel configured to receive the stabilizing member when the first and second jaw members are in a closed configuration.

Abstract: A clip applier may be configured to apply a surgical clip and have a pair of jaw members. Each of the jaw members may have an inner surface and a stabilizing member extending from the inner surface. Each of the jaw members may be configured to engage a distal portion of a leg member of the surgical clip. The stabilizing members may be configured to be positioned on opposite lateral sides of a proximal portion of the surgical clip to reduce lateral movement of the surgical clip. An inner portion of each of the stabilizing members may be spaced apart from the opposing jaw member in an open configuration, and each of the jaw members may have a channel on the inner surface to receive the opposing stabilizing member in a closed configuration.

Abstract: A cartridge may include a pair of side walls separated by a compartment, the compartment being configured to receive a surgical clip, and a base member supporting the pair of side walls. The pair of side walls may extend at an acute angle relative to a vertical axis of the base member to hold the surgical clip at the acute angle. The acute angle may be greater than 10° and/or about 20-30°. The cartridge may also include a pedestal extending between the pair of side walls and configured to support the surgical clip, where the pedestal is disposed at the acute angle. The cartridge may further include a retainer configured to retain the surgical clip in the compartment, the retainer including a pair of fingers configured to contact the surgical clip, where the pair of fingers are oriented at the acute angle.

Abstract: A surgical clip may include first and second leg members, each having inner surfaces. The inner surface of the first leg member may be concave and the inner surface of the second leg member may be convex. The surgical clip may include a first locking member positioned on a distal end portion of the first leg member, and a second locking member positioned on a distal end portion of the second leg member. The surgical clip may also include a third locking member position between a proximal end portion and the distal end portion of the first leg member, and a fourth locking member positioned between a proximal end portion and the distal end portion of the second leg member. The first and second locking members, and the third and fourth locking members may be configured to interact to secure the surgical clip in a closed configuration.

Abstract: In a method of integrating an active pharmaceutical ingredient (API) with a thermoplastic polymer, the thermoplastic polymer and API are into a first feed port of a multi-screw extruder or the thermoplastic polymer is fed into the first feed port of a multi-screw extruder, the thermoplastic polymer is conveyed along the heated multi-screw extruder while heating the thermoplastic polymer to a melt temperature of 160° C.-280° C. prior to the thermoplastic polymer being conveyed past a second feed port and the API is fed into the second feeding port in the heated screw extruder to mix with the melted thermoplastic polymer to generate a compounded mixture containing 85-100% of the starting API content. The compounded mixture is extruded from an outlet of the heated screw extruder and cooled via a cooling device such that the compounded mixture contains 85-100% of the starting API content.

Abstract: Apparatus and methods are provided for treating a tissue opening, for example a trocar opening used in a minimally invasive surgical procedure. In a tissue closure device, a finger guard or shield can be used, handle or holding area or areas can be used, and positioning indicators can be used. A resiliently flexible target material can also be used for reliably holding a suture during the procedure. Introducers can be used having a suture holder, an alignment indicator and insertion limits.
