20120238957 | SURGICAL SEALING ELEMENT HOLDER FOR HOLDING A SURGICAL SEALING ELEMENT AND SURGICAL SEALING SYSTEM - In order to improve a surgical sealing element holder for holding a surgical sealing element of a surgical sealing system comprising a trocar with a trocar sleeve, the sealing element having an insertion opening which can be widened, such that a sealing element of the sealing system can be replaced in a simple and reliable manner and it is ensured that sealing in relation to a channel of the trocar sleeve is perfect at all times it is suggested that a holder sealing element be provided for sealing the sealing element holder with respect to an inner wall surface of the trocar sleeve. In addition, an improved surgical sealing system is provided. | 09-20-2012 |
20120253285 | Cannula Seal - Trocar seal assemblies are disclosed which consist of a helically-shaped seal positioned within a trocar's cannula; wherein, as an instrument is inserted through the central bore of the helically-shaped seal, the helically-shaped seal expands, thereby increasing the diameter of the central bore. In other embodiments, a protective member is positioned within a retaining member; wherein the protective member is configured as a helix and, as an instrument is inserted through the central bore of the helix, the helix expands, thereby increasing the diameter of the central bore. | 10-04-2012 |
20130006185 | ACCESS ASSEMBLY WITH FLEXIBLE HOUSING - An access assembly includes a housing defining a longitudinal axis and having a longitudinal opening therethrough, a cannula extending distally from the housing and in fluid communication with the longitudinal opening and a seal member mounted within the longitudinal opening of the housing. The seal member is configured to receive an instrument therethrough in substantial sealed relation therewith. The housing is adapted to move in at least a radial direction with respect to the longitudinal axis whereby the seal member maintains the substantial sealed relation relative to the instrument as the instrument in manipulated. The housing may be flexible and capable of deflection relative to the longitudinal axis. The housing may comprise an elastomeric material in whole or in part.
