An implantable prosthesis for repairing an anatomical defect, such as a tissue or muscle wall hernia, including an umbilical hernia, and for preventing the occurrence of a hernia at a small opening or weakness in a tissue or muscle wall, such as at a puncture tract opening remaining after completion of a laparoscopic procedure. The prosthesis includes a patch and / or plug having a body portion that is larger than a portion of the opening or weakness so that placement of the body portion against the defect will cover or extend across that portion of the opening or weakness. At least one tether, such as a strap, extends from the patch or plug and may be manipulated by a surgeon to position the patch or plug relative to the repair site and / or to secure the patch or plug relative to the opening or weakness in the tissue or muscle wall. The tether may be configured to extend through the defect and outside a patient's body to allow a surgeon to position and / or manipulate the patch from a location outside the body. An indicator may be provided on the tether as an aid for a surgeon in determining when the patch or plug has been inserted a sufficient distance within the patient. A support member may be arranged in or on the patch or plug to help deploy the patch or plug at the surgical site and / or help inhibit collapse or buckling of the patch or plug. The patch or plug may be configured with a pocket or cavity to facilitate the deployment and / or positioning of the patch or plug over the opening or weakness.

Laparoscopic instruments and cannulas are provided for performing laparoscopic procedures entirely through the umbilicus. Generally S-shaped laparoscopic instruments placed through the C-shaped trocar sleeves or through the cannula and instrument holder unit provide markedly improved degrees of instruments' freedom during trans-umbilical laparoscopic procedures.

This invention provides hermetically-sealed handle assembly with a rotating trigger for use with disposable components, such as surgical clip appliers. The rotating trigger reduces the gripping force necessary to fully control the internal actuator mechanism to operate a disposable surgical clip applier to fully ligate a vessel or other tissue. The hermetic seal on the handle assembly prevents any patient fluids and other bioburden from entering the internal structures. This reduces the possibility of cross-contamination and the costs of sterilization.

Provided are surgical instruments, and more particularly, surgical instruments that may be manually operated to perform laparoscopic operations or various surgical operations.

A laparoscopic device assembly provides a tubular diaphragm twist seal that responds to a slight rotation of an actuating ring in a first direction by coupling a motor spring power assisted rotation of a bottom circumference of the twist seal achieves a pneumatic seal in an adjustable access channel defined by the state of the twist seal for maintaining an insufflated body cavity for a hand assisted laparoscopic surgical procedure. A slight rotation of the actuating ring in an opposite second direction releases compression spring energy and energy in the twisted state of the twist seal so that an upper circumference of the twist seal is allowed to open the adjustable access channel.
