The mechanism may be adapted for reciprocal longitudinal movement within the housing between a first position corresponding to a first dimension of the passageway and a second position corresponding to a second dimension of the passageway. The mechanism may include a single seal element or first and second seal elements. The seal elements may be adapted for lateral movement during longitudinal movement of the seal. The first and second seal elements may be in at least partial overlapping relation when in the first position of the seal.Type: GrantFiled: July 11, 2011Date of Patent: October 23, 2012Assignee: Tyco Healthcare Group LPInventor: Russell Heinrich

Patent number: 8292853Abstract: The present invention relates to a surgical access device comprising an elongate tubular member having a working channel and a proximal end and a distal end, a septum seal integrally formed at the distal end of the tubular member, and a zero seal disposed at the distal end of the tubular member and distal to the septum seal, the zero seal being sized and configured to seal when no instrument is in place within the working channel of the tubular member, and the zero seal being coupled to the septum seal The zero seal may be a duckbill seal having opposing lip portions separated by a slit portion. The opposing lip portions are coated with or attached to a soft or occlusive material.Type: GrantFiled: March 24, 2004Date of Patent: October 23, 2012Assignee: Applied Medical Resources CorporationInventors: Charles C. Hart, John R. Brustad

Patent number: 8273060Abstract: 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: September 25, 2012Assignee: Ethicon Endo-Surgery, Inc.Inventors: Cesar E. Moreno, Jr., Patrick J. Minnelli, Thomas A. Gilker, Daniel J. Mumaw, Rebecca J. Mollere, Randall Tanguay

Patent number: 8241251Abstract: A seal assembly for use with an access device during a surgical procedure includes a housing having a passageway therethrough dimensioned to permit passage of a surgical instrument and being adapted for mounting to a trocar device, and a seal comprising a gel material and being mounted to the housing across the passageway. The seal includes inner seal portions defining an access channel dimensioned to form a substantial sealing relation with an object therethrough and substantially close in the absence of the surgical instrument. The seal preferably comprises a second material having a hardness greater than a hardness of the gel material. The gel material may be selected from the group consisting of urethane gel, silicone gel.Type: GrantFiled: August 25, 2004Date of Patent: August 14, 2012Assignee: Tyco Healthcare Group LPInventor: Richard D. Gresham

Publication number: 20120172807Abstract: A surgical access port comprises a valve or instrument seal that separates the instrument contact function from the instrument conforming function. Embodiments of the instrument seal comprise in instrument contact element that extends through an opening in a compression element, thereby defining an instrument orifice that seals with an instrument extending therethrough. Embodiments of the instrument contact element comprise a non-distensible membrane or film, for example, as a tube or cylinder.Type: ApplicationFiled: March 14, 2012Publication date: July 5, 2012Applicant: Applied Medical Resources CorporationInventors: Jeremy J.

Patent number: 8206357Abstract: A surgical portal apparatus is provided which includes a housing and a portal member. The portal member is connected to the housing which extends therefrom. The portal member has a longitudinal axis which includes a longitudinal passageway for permitting a surgical object to pass therethrough. A seal mount is mounted to the housing and has an internal seal adapted to establish a substantial sealed relation with the surgical object, the seal mount adapted to articulate relative to the housing between a first position relative to the housing and at least one second position relative to the housing, the seal mount being normally biased toward the first position.Type: GrantFiled: February 8, 2010Date of Patent: June 26, 2012Assignee: Tyco Healthcare Group LPInventor: Michael J. Bettuchi

Patent number: 8197452Abstract: A vascular access device may include a body and a layer of the body that communicates with a pathogenic environment to discourage adhesion of a pathogen to the layer and thus repress pathogenic activity. A method of repressing pathogenic activity in a vascular access device includes providing the device with a body, and coating the body with a layer that discourages adhesion of a pathogen to the layer.Type: GrantFiled: July 26, 2007Date of Patent: June 12, 2012Assignee: Becton, Dickinson and CompanyInventors: Weston F. Harding, Austin Jason McKinnon, Mark A. Crawford, Lantao Guo, Glade H. Howell, David Ou-Yang
