  • Patent number: 10967152
    Abstract: An expandable medical sheath can include a sheath body having a lumen that extends between proximal and distal ends of the sheath. The sheath can have first and second members where the first member has a different elastic modulus than the second member such that one provides elasticity to the sheath and the other provides column strength. The first and second members can be coupled together in alternating sections to form the tubular sheath or the stiffer members can be embedded in the elastic member along all or a portion of the longitudinal length of the sheath. The sheath can automatically move to an expanded state to allow a larger diameter medical device to pass through the lumen, and once through the sheath can automatically return to its initial diameter.

The seal assembly can be positioned at any location along the length of the at least one longitudinal port. The seal assembly comprises a seal housing which is dimensioned to receive a surgical instrument inserted into the at least one longitudinal port and form a substantially fluid-tight seal therewith. The seal housing may comprise a pivotable member to pivot the surgical instrument inserted therein. The at least one longitudinal port may define two gradually enlarging openings to facilitate the maneuverability of the surgical instrument inserted therein. The at least one longitudinal port may comprise a protective sleeve to protect it from accidental penetration by the surgical instrument.

  • Patent number: 9113949
    Abstract: Devices, systems, and methods for immobilizing an implanted catheter tip while the catheter is anchored relative to surrounding tissue. In one embodiment, a cannula system is included that incorporates a cinch tube for guiding the catheter to a target site within a body. The cinch tube may define a cinch window to receive therein a cinch member operable to immobilize and occlude the catheter. The cinch tube may also include an elongate opening proximate the cinch window. The elongate opening allows extraction of a portion of the catheter and subsequent severing of the catheter above the cinch window/occlusion site.

  • Patent number: 9022985
    Abstract: 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. The seal member may be integrally formed with the housing. The housing may include at least one flexible ring portion and possibly a plurality of ring portions.

  • Patent number: 8951229
    Abstract: A catheter includes a pressure actuated seal within a manifold. A catheter body is coupled with the manifold, and a manifold lumen and a catheter lumen are configured to receive pressurized fluids. The pressure actuated seal includes a pressure actuated seal element having a seal element lumen. The seal element lumen is in communication with the manifold and catheter lumens. The pressure actuated seal element is deformable between an open configuration and a sealed configuration. In the sealed configuration, the pressurized fluids in the manifold press on the pressure actuated seal element along a first seal face. The pressure actuated seal element compresses inwardly around the seal element lumen according to a pressure of the pressurized fluids. In the open configuration, the pressure actuated seal element relaxes in an absence of the pressurized fluids, and the seal element lumen is open and configured to allow passage of an instrument.
