  • Patent number: 11547397
    Abstract: Devices, systems and/or methods for fixating soft tissue to bone are provided. In one embodiment, a repair device for fixating soft tissue to bone with a bone anchor includes a soft tissue anchor and one or more flexible members. The soft tissue anchor includes a base with multiple legs extending from the base. The one or more flexible members are coupled to the base and configured to extend from the base to the bone anchor with a fixed length. With this arrangement, the fixed length of the one or more flexible members is configured to maintain a fixed distance between the soft tissue anchor and the bone anchor such that, as the bone anchor is seated into bone, the one or more flexible members pulls the soft tissue anchor down against the soft tissue to fixate the soft tissue to the bone.

  • Patent number: 11541490
    Abstract: Treatment of aneurysms can be improved by use of a treatment system including a conduit have a distal portion, a coupler slidably coupled to the distal portion, an occlusive member coupled to the coupler, and a securing member coupled to the conduit proximal to the coupler. The securing member can include a distal end portion that is removably coupled to the coupler. In some embodiments, the securing member can have a shape and/or be treated such that the securing member self-expands to decouple itself from the coupler during deployment of the occlusive member. In some embodiments, movement of the conduit relative to the coupler causes the securing member to decouple from the coupler.

  • Patent number: 11491007
    Abstract: A flow diversion device configured in accordance with embodiments of the present technology may include, for example, a housing including openings to channels that intersect at a junction. The flow diversion device may also include, for example, a flow control component disposed at the junction and movable to selectively form pathways for fluid communication based on a position of the flow control component. For example, when the flow control component is in a first position, a first pathway may allow fluid flow causing deployment of the prosthetic heart valve device and, when the flow control component is in a second position, a second pathway may allow fluid flow causing recapture of the prosthetic heart valve device. The flow diversion device may include a handle movable to position the flow control component in the first or second positions thereby selectively controlling fluid flow of the delivery system.

  • Patent number: 11478246
    Abstract: A surgical gripping/holding instrument having two instrument branches which are coupled pivotably with respect to one another. Each branch has a distal gripping/holding portion, a proximal instrument actuating portion, and an intermediate region which connects the distal and proximal portions preferably integrally, and having an instrument lock, of which the locking elements which can be brought into latching engagement with one another are arranged or formed on the instrument branches. The actuation of the instrument for opening and closing is functionally separated from actuation of the instrument for locking and unlocking the instrument by the positioning of the instrument lock in the intermediate region of the instrument. Therefore, each actuation can be carried out individually.

  • Patent number: 11452628
    Abstract: Loading systems for prosthetic heart valve devices are disclosed. A loading funnel is provided within a watertight interior space that is at least partially filled or fillable with biocompatible fluid. Funnel may have a cylindrical end to which is connected a delivery catheter having a lumen that will receive the collapsed prosthetic heart valve device. An expanded prosthetic heart valve device may be placed within the funnel and pushed or pulled into the funnel which provides a predictable, reliable and repeatable surface for collapsing the prosthetic heart valve device. Ultimately the prosthetic heart valve device is collapsed and translated into the lumen of the delivery catheter for further translation therealong and release into the heart chamber of interest.

  • Patent number: 11426193
    Abstract: A tissue-removing catheter for removing tissue from a body lumen during a cutting operation includes an elongate catheter body configured for insertion into the body lumen and a tissue-removing element. A motor is operably connected to the tissue-removing element for rotating the tissue-removing element. A sensor is configured to detect a parameter of the catheter body during the cutting operation. A motor control circuit is in electrical communication with the sensor and the motor. During an operational control function, the motor control circuit is configured to receive a signal from the sensor based at least in part on the detected parameter, determine whether the received signal is indicative of inefficient movement of the tissue-removing element, and adjust a rotational speed of the tissue-removing element to increase efficiency of the tissue-removing element if the received signal is indicative of inefficient movement of the tissue-removing element.
