  • Patent number: 11642498
    Abstract: Aspects of this disclosure relate to catheter assemblies, that include an inner tube component, an outer tube component that fits over the inner tube component, and a disposable layer of film that isolates the otherwise fluid-exposed portions of the catheter from the fluid it drains. This disposable film can be removed at regular intervals and obviates the need for catheter exchanges as the isolating disposable film, rather than the catheter itself, is removed. The principal characteristic of the disposable film is that it is relatively impermeable to fluid, for example, bodily fluids.

  • Patent number: 11266400
    Abstract: A knotless self-cinching suture construct device includes a shuttling suture, a continuous loop and a self-cinching suture member. The shuttling suture is configured for insertion into a passage hole in injured soft tissue, such as a torn or damaged meniscus in the knee. The shuttling suture and continuous loop are passed entirely through the passage hole in the tissue, and the self-cinching suture member is inserted through the continuous loop to form a hitch using the continuous loop around the tissue. The self-cinching suture member is then pulled tight, allowing a first strand to slide through both the hitched continuous loop and a self-cinching sleeve on the suture member. When tension is applied, the sleeve tightens around the strand much like a finger trap, preventing inadvertent release of the applied suture tension. The suture construct is configured for use through a transosseous tunnel with a suture button in some embodiments.

  • Patent number: 11246705
    Abstract: A method for delivering an implant including, a catheter having a shaft defined by a proximal end and a distal end and a bore extending therethrough; a first joint in the shaft, and a second joint in the shaft located distal of the first joint. The first joint and the second joint are separated by a first digit sized to receive the implant and located between the first joint and the second joint. The second joint and the distal end are separated by a second digit being sized to receive the implant. The implant is advanced through the first digit and into the second digit without bending the implant or the first and second digits by rotating the digits at the first joint and the second joint.

  • Patent number: 11197660
    Abstract: An asymmetric occlusion device for occluding an opening in a body tissue where part of the opening is defined by a partial inadequate rim. The asymmetric occlusion device includes a waist portion having a distal end extending to a proximal end. The waist portion is of non-woven material extending around a longitudinal axis opening. The occlusion device further includes a pair of asymmetric occluder disks attached to the waist. The asymmetric distal and proximal occluder disks are formed of shape memory material. The asymmetric occluder disks include a short arm extending from the waist and an extended arm extending from the waist. The extended arm exceeds the length of the first short arm. The density of the first short arm exceeds the density of the second extended arm.

  • Patent number: 11185318
    Abstract: A system to facilitate sealing a puncture of a vessel includes an implant having first and second expandable sections, and a delivery device that includes an inner tube and a circumscribing outer tube. The outer tube defines a first lumen configured to retain the implant, and a second lumen configured to channel fluid from the vessel through a distal opening proximal to the implant. A pusher circumscribed at least partially by the outer tube is configured to compress the implant to selectively expand the first and second expandable sections. The outer tube is selectively retractable relative to the inner tube such that the first expandable section remains substantially within the first lumen and the second expandable section is positioned outside of the first lumen. The outer tube is further selectively retractable relative to the inner tube such that the first expandable section is positioned outside of the first lumen.
