An operative cannula includes an elongate shaft that includes a wall structure and a channel extending along the wall structure. The wall structure defines an interior pocket sized to receive a tubular member and is configured to grasp the tubular member when the tubular member is disposed within the interior pocket. The channel is configured to allow passage of an instrument from a proximal end region of the elongate shaft through a distal end region of the elongate shaft.

The invention relates to methods of increasing the genetic progress of a line, breed or herd of swine through the use of sex-selected sperm cells in artificial insemination techniques. The invention also encompasses methods of artificially inseminating a swine via deep intrauterine catheter or via a laparoscopic procedure, which allow the use of reduced doses of sex-selected sperm cells.

A device which illuminates internal tissue and organs of a patient. The illumination member includes an array of light-emitting diodes (“LEDs”). The arrangement of the array depends on the configuration of the device and the procedure for which the device is being used. In all cases, the illumination member is used to illuminate relevant organs or structures in the body in order to increase visibility during surgical procedures. The LED array reduces the potential for inadvertent injury to internal structures for procedures located throughout the body. These procedures include those involving the reproductive organs of males and females, gastric and bariatrics, and other structures in the abdomen.

A probe for resecting and coagulating tissue comprises an outer sleeve having a tissue cutting window and an inner sleeve having a tissue cutting distal end. And RF cutting region is formed at the distal end of the inner member and an RF coagulation region is formed on an exterior surface of the inner member immediately proximal to the cutting surface. A single power supply providing a single RF energy mode can be connected to both RF applicator regions to simultaneously cut and coagulate tissue.

An anti-slip speculum grip for use in vaginal medical procedures, including a speculum including a speculum blade having an anterior and a posterior side and a speculum handle, and an anti-slip speculum grip operatively attached to a portion of the posterior side of the speculum blade, wherein the anti-slip speculum grip is further comprised of; an anti-slip speculum grip base having a first side and a second side, an adhesive layer located adjacent to the first side of the anti-slip speculum grip base and adjacent to the portion of the posterior side of the speculum blade in order to operatively attach the anti-slip speculum grip to the posterior side of the speculum blade, an x-ray detector device located between the anti-slip speculum grip base and the adhesive layer, a speculum grip textured side located on the second side of the anti-slip speculum grip base, wherein the speculum grip textured side is further comprised of; a plurality of raised areas arranged on the speculum grip textured side in a predetermined pattern, wherein the raised areas interact with vaginal tissues to provide absorptive friction between the vaginal tissues and the speculum thereby preventing the speculum from slipping out/falling out of a vaginal canal during a vaginal medical procedure.

A speculum is provided, comprising two or more blades moveable between an open and a closed position. A polyisoprene or silicone tubular sheath is attached to at least one of the blades, the sheath being arranged to retain the lateral walls of the body cavity when the blades are in the open position. Sheath attachment means provided on one of the speculum blades facilitate attachment of the sheath to the blade, the attachment means comprising at least one patch or strip of adhesive material extending in a longitudinal direction of the blade.

A cavity illumination system according to the present disclosure may include one or more illumination elements composed of a transparent or semi-transparent, biocompatible sterilizable polymer and one or more illumination sources. The sterilizable polymer operates as a waveguide. An illumination element may incorporate micro structured optical components such as for example gratings, prisms and or diffusers to operate as precision optics for customized delivery of the light energy. The micro structured optical components may also be used to polarize and/or filter the light energy entering or exiting the illumination element.
