Patent number: 8870747Abstract: The present invention generally provides methods and devices for removing fluid from a surgical instrument. Surgical access devices and seal systems are generally provided having one or more valves or seal assemblies to create a closed system between the outside environment and the environment in which the surgical access device is being inserted. In one embodiment, a seal assembly is provided and can include a seal having an opening configured to receive a surgical instrument therethrough and a fluid remover in the form of an absorbent element, a scraper element, a wicking element, or any combination thereof can be associated with the seal and configured to remove fluid from the opening and/or a surgical instrument.Type: GrantFiled: April 28, 2008Date of Patent: October 28, 2014Assignee: Ethicon Endo-Surgery, Inc.Inventors: Cesar E.

Patent number: 7967748Abstract: A laparoscopic disk assembly for a Hand Assisted Laparoscopic Surgery (HALS) procedure includes an exteriorly visible laparoscopic disk (seal cap) attached to a retractor skirt. The laparoscopic disk provides an adjustable exterior opening. A downward annular surface is supported by an attached flexible or resilient (“soft) support member that in turn forms an annular contact upon a patient's abdomen wall surrounding an incision to form a sealing connection, to facilitate improved manipulation or degrees of freedom through the laparoscopic disk without loss of insufflation pressure, to minimize, if not eliminate, bruising, to prevent rotation movement of a retractor skirt in the incision, and to reduce fatigue. Versions include a resilient pad, a resilient skirt that adheres to the patient's skin, a skirt with horizontal pleats, and a toroidal bladder that comfortably depresses into the skin.Type: GrantFiled: December 15, 2006Date of Patent: June 28, 2011Assignee: Ethicon Endo-Surgery, Inc.Inventors: Paul H.
