An active cannula which does more than merely maintain a passage is usable to create and / or enlarge a passage, to position a scope or instrument, to move or locate tissue, etc. The cannula can vary in size or shape as needed, intraoperatively. Because a cannula of the present invention is expandable, the surgeon can make a relatively small incision, stretch the tissue with the expandable cannula, contract the cannula and remove it, allowing the skin to come back to its unstretched condition. Thus, a smaller incision can be made to fit the same size instrument. The cannulas can assume such a non-circular shape, to fit into a natural skin opening and cause less trauma. The devices can be used to seal off a space, expand an existing space or a potential space for working or visualization, move tissue (for example, to stretch an incision), or protect tissue.

A surgical device for removing implanted devices includes a sleeve device with an elongated trough portion arranged to extend through a skin opening and be positioned subjacent to a particular implanted device. A removable knife assembly is inserted through a tubular portion of the sleeve device and is used to incise scar tissue from a proximal end of the implanted device. The implanted device is then manipulated through the opening in the surrounding scar tissue and deposited on the trough portion of the sleeve device whereupon it is removed through the skin opening. The surgical device may also include a removable trochar device slidably engaging the tubular portion of the sleeve device and penetrating flesh to the implanted device.

A zipper-type wound closer attachable to the skin around a skin opening and zipped closed to pull the skin opening closed. The wound closer includes two elongated connecting strips whose feet are pre-coated with adhesive and attached to the skin around the skin opening. The edges of the wound are trimmed flush with the interior sides of connecting strips, and the strips are then zipped together by moving a slider along the connecting strips to join the strips together like a familiar zipper. The wound zipper forms a continuous, toothless seam to prevent seepage of fluid through the seam. By holding the freshly trimmed edges of the skin opening together immobile in a clean, firm, closely aligned connection, the wound closer recreates the conditions under which scar-free healing of the skin can occur naturally; useful for repairing wounds and removing existing scars.

An external fixation assembly includes a plurality of hollow pins that are inserted into a patient's bone. Each pin has an interior bore and a plurality of apertures extending through the pin wall from the bore. The pin may be coupled to a source of vacuum pressure operable to create reduced pressure in the tissue surrounding the pin. A cover is placed around the pin and sealed to provide a fluid-tight enclosure that maintains reduced pressure around the pin. A method for applying external fixation using the fixator pins described above includes the steps of inserting each pin through a skin opening, positioning the pin apertures near selected tissue, covering the skin opening with a sealed enclosure, connecting the pins to a source of vacuum pressure, and activating the source of vacuum pressure to create reduced pressure in the patient's tissue at or near the bone.

The present invention relates to a component (1) for forming a seal around an opening in the skin (8). According to the invention, the component (1) comprises a carrier (2) which is enclosed between layers of soft and skin-compatible adhesive.

Hollow core door apparatus for preventing the build up of pressure in a room having a register through which air flows into the room and a center panel in the door with at least a single opening through the center panel; the door has an inside door skin and an outside door skin, both of which include openings spaced apart from the center panel, and an inside panel and an outside panel disposed in the respective openings in the inside and outside door skins. The inside and outside panels are spaced apart from the center panel within the respective door skin openings, and the spacing within the door skin openings define peripheral openings at least as great as the area of the opening in the center panel and are offset from the opening in the center panel to provide for a non-linear flow of air through the door to prevent the build up of pressure in the room. Several different embodiments are illustrated. An embodiment combining a noxious gas absorbent material with the pressure build up prevention capabilities is also illustrated.

The invention relates to a hair trimmer (1) comprising a fixed cutting element (20') having teeth on the front side thereof, and a mobile cutting element (20'') which has teeth on the front side thereof and is oscillable in relation to the fixed cutting element (20'), so that, when the hair trimmer (1) is used, hairs reaching between the teeth of the fixed cutting element and the mobile cutting element are cut off. The risk of using such a hair trimmer is that the skin can be caught between the teeth or the teeth can penetrate into skin openings such as capillary ducts, leading to painful skin injuries. In order to avoid these injuries, the hair trimmer also has a protective support (3) which has teeth (4) on its front side, is arranged on the fixed cutting element (20'), and used to place the hair trimmer (1) on the skin of the user. The teeth (4) of the protective support (3) lock with the teeth of the fixed cutting element (20') on the front side or slightly extend over the teeth, and the teeth (4) of the protective support (3) lie on the fixed cutting element (20'), essentially without gaps.

The invention relates to a method for creating a puncture wound for obtaining a sample of a body fluid from a body part in which a skin opening is created at a puncture site in the epidermis in a skin-opening step. Then, in a sample collection step a sample collection puncture is executed by using a puncture element with which the skin opening is deepened with the puncture element, thereby creating a puncture wound for obtaining the sample. The invention also relates to a handheld apparatus for implementing this method.

A catch basin insert arranged to help filter out trash and debris as water passes through the catch basin. One embodiment of a catch basin insert according to the present invention comprises a mounting frame and a skin mounted to the mounting frame, the skin having openings to allow water and other liquids to pass through. The insert further comprises a means for mounting the frame to a wall over an opening, and includes a top opening not covered by the skin. The top opening has one or more openings larger than said skin openings to allow a greater volume of water to pass.
