Abstract: A seal assembly includes a first seal and a second seal and positioned in the first end element. The second seal can include at least one longitudinal groove therein and have members connected thereto. A stopper member is coaxially positionable within the second seal and the first seal and a lubricant can be positioned between the stopper member and the second seal. The seal assembly can also be integrated with a capsule for removable insertion within a tubular member.

Abstract: A surgical device including a cutting blade; a guard portion movable with respect to the blade from a first position covering the blade to a second position exposing the blade; an actuator shaft; a biasing element; an integrally formed locking element; and a handle having a cavity configured to receive the locking element.

Abstract: A seal assembly includes a first seal, a second seal, and a positioning element. The first seal includes at least one longitudinal slot therein. The second seal includes at least one longitudinal slot therein and is positioned coaxially with the first seal. The positioning element is positioned coaxially with the first seal. The at least one longitudinal slot of the first seal is offset from the at least one longitudinal slot of the second seal in a radial direction from a longitudinal axis of the seal assembly. The seal assembly can be integrated with a closing valve. The seal assembly can also be integrated with a capsule.

Abstract: A modular seal and valve assembly which includes a seal and passageway, the seal having a cross-sectional diameter which converges in a direction of passage of an instrument through the passageway. The seal includes at least one seal engaging member which is engageable with the seal for biasing the passageway of the seal so as to be normally closed while still permitting passage of an instrument therethrough upon overcoming the biasing course of the at least one seal engaging member. The method of sealing the passageway including the step of providing the seal and engaging the seal with the at least one sealing member.

Abstract: A surgical device including a penetrator configured to pierce a membrane of a patient and a guard positionable to permit and to prohibit the penetrator from piercing the membrane. The guard includes a shield member movable along a longitudinal axis between a first position covering the penetrator and a second position uncovering the penetrator, the shield member including a stop member; a locking member configured to contact the stop member to prohibit the shield member from moving from the first position to the second position; and an unlocking member surrounding a portion of the shield member and configured to move along the longitudinal axis to move the locking member out of contact with the stop member to permit the shield member to move from the first position to the second position.

Abstract: A surgical device includes a sealing member forming a gas tight seal with an instrument disposed in an opening of the sealing member. The sealing member includes a seal ring connected to the interior of the handle, and a conical section having the instrument disposed therein. In an embodiment, the conical section is connected to the seal ring and has a height at least as large as a diameter of a base of the conical section before disposing the instrument therein. In another embodiment, first and second elastic protrusions have the instrument disposed therein, the elastic protrusions contacting one another to form the gas tight seal. In another embodiment, a first section is connected to the seal ring, and a second section is connected to the first section and has the instrument disposed therein. The sealing members, as well as methods of sealing with the sealing members are also disclosed.

Abstract: A surgical device and method for endoscopic surgical procedures capable of preventing injuries to internal organs during insertion. The surgical device can include one or more of the following: a multiple system of sharp blade edges or a single blade, a mechanical tissue protection device that includes a series of thin plastic guards sliding along the sides of the planar knives and having an angle between their edges smaller than that of the cutting knife edges, one or more fixed conical deflectors to expand the cut tissue passage leaving the guards to contact tissue contact only at their tips, an insufflation passage configured to transport fluid into the body cavity during penetration, a locking system for the guards that prevents accidental reuse of the cutting features, and/or an ergonomic design which facilitates handling.
