  • Patent number: 10925729
    Abstract: Delivery devices for delivering a stented prosthesis to a target site are disclosed. Certain disclosed delivery devices include a handle assembly including an actuator, a shaft assembly interconnected to the handle assembly, and are configured to releasably retain the stented prosthesis to the delivery device with at least one elongate tension member. The delivery devices further include a torque shaft that is configured to apply and adjust the amount of tension in the each tension member. For example, the torque shaft can be configured to wind and unwind each elongate tension member around the torque shaft to correspondingly compress and expand the stented prosthesis. The torque shaft can be controlled with an actuator provided in the handle assembly, for example. In some embodiments, the actuator is further configured to axially move the torque shaft.

  • Patent number: 10918511
    Abstract: An intragastric balloon device including a deformable material is in an ingestible form for delivery to a stomach of a patient, expands in response to stimuli in the stomach, and degrades within a limited duration (such as 16 hours or some other value between 2 hours and 72 hours) to diminish to passable form in which remains of the intragastric balloon device are passable from the stomach. In an illustrative example, the deformable material is composed of silicone coated with parylene and encloses perfluoropentane fluid that transitions from liquid to gas due to stomach temperature to inflate the balloon in the stomach and occupy space in the stomach until a fuse of methacrylate erodes to unblock a vent conduit to permit escape of the perfluoropentane for deflating the balloon to diminish to passable form.

  • Patent number: 10912553
    Abstract: Apparatus and methods for Achilles tendon repair are described where an elongate tendon repair assembly may be introduced into a single incision to access the damaged tissue. The assembly may define a channel for receiving a portion of the tendon and which may provide support to the tissue during repair. One or more retractable needles each carrying a length of suture may be deployed within the channel for piercing through the tendon and a cinching member may secure each of the suture lengths for tensioning the suture against the damaged tendon. Once the suture lengths have been deployed, the needles may be retracted and the device removed from the incision.

  • Patent number: 10881494
    Abstract: The embolic protection device (10) has an expandable tubular structure supporting a filter mesh material (12). The embolic protection device is compressed to a small diameter for insertion into a patient's aorta, then expanded within the aorta with the filter mesh material positioned to allow blood to enter sidebranch vessels connected to the aorta and to prevent embolic material from entering the sidebranch vessels. The filter mesh material may be configured with waves or undulations (26) for increased surface area and/or with two layers of mesh material to provide additional protection against embolization and to prevent inadvertent occlusion of the sidebranch vessels.

  • Patent number: 10842525
    Abstract: The present embodiments provide apparatus and methods for treating tissue by applying a force to the tissue. In one embodiment, the apparatus comprises a deployable segment having proximal and distal regions, a main body extending therebetween, and a loop member formed at the distal region of the deployable segment. A cannula having a bore is dimensioned to circumferentially surround at least a portion of the main body at a location proximal to the loop member, and a spring member is disposed between the cannula and the loop member. The proximal end of the spring member is affixed to the cannula, and the distal end of the spring member is movable to apply a compressive force to adjust the size of the opening of the loop member and compress tissue disposed within the opening of the loop member. In an alternative embodiment, the cannula is omitted, and a diameter of the loop member is configured to be reduced and increased any number of times before final deployment of the deployable segment.

  • Patent number: 10842515
    Abstract: Embodiments are directed to electro-hydraulically actuated lithotripters and methods for fragmenting stones using such lithotripters. In an embodiment, a lithotripter apparatus for fragmenting at least one stone in a body is disclosed. The lithotripter apparatus includes a chamber configured to contain an electro-conductive fluid, which includes a proximal end wall and a distal end wall spaced from the proximal end wall. A chisel is coupled to the chamber and located at least proximate to the distal end wall. A proximal electrode is located at least partially in the chamber. A distal electrode is located at least partially in the chamber and spaced from the proximal electrode. Responsive to an effective voltage applied between the proximal and distal electrodes, the proximal and distal electrodes are configured to electrically discharge into the electro-conductive fluid to generate shock waves in the chamber that accelerate the chisel toward the at least one stone.

  • Patent number: 10813642
    Abstract: The invention is an implantable magnetic anastomosis device having an exoskeleton that directs self-assembly. The design allows the device to be delivered in a linear configuration using a minimally-invasive technique, such as endoscopy or laparoscopy, whereupon the device self-assembles into, e.g., a polygon. A coupled set of polygons define a circumscribed tissue that can be perforated, or the tissue can be allowed to naturally necrose and perforate. The device can be used to create anastomoses in a variety of tissues, such as tissues found in the gastrointestinal, renal/urinary, and reproductive tracts. New procedures for using anastomoses, e.g., surgical bypass are also disclosed.

  • Patent number: 10813646
    Abstract: A left atrial appendage occluder includes a sealing plate, a fixing plate, and a connection member connecting the sealing plate and the fixing plate. The connection member is a silk woven structure. A radial deformability of the sealing plate is greater than a radial deformability of the fixing plate, and/or an axial deformability of the sealing plate is greater than an axial deformability of the fixing plate. In the left atrial appendage occluder, the fixing plate and the sealing plate are connected via the connection member of the silk woven structure, such that a distance between the fixing plate and the sealing plate and an angle formed thereby are both adjustable to adapt to a left atrial appendage having a large bending angle or requiring the fixing plate to remain at an increased distance to the sealing plate, thereby reducing the risk of failed occlusion.
