  • Patent number: 11000300
    Abstract: A vascular snare system and method for extracting elongated objects such as pacemaker pacing leads or defibrillator leads from the vasculature of a patient are provided. The system utilizes a sheath having a lumen through which two wire elements are deployed to snare and extract a lead. Each wire element has a magnet disposed at its distal end.

  • Patent number: 11000368
    Abstract: This intraocular lens (IOL) injector cartridge has a proximal opening in a main body for receiving an IOL. The main body has a lumen that extends longitudinally to a distal end having an opening smaller than the IOL. Passage through the lumen compresses or rolls the IOL so that when the distal end is inserted through a small incision in the eye the IOL can be expelled into the capsular bag. The distal end of the cartridge is beveled with a leading tip in front of a trailing heel. The characteristics of the beveled end are such that damage to the IOL is reduced. The bevel may be straight or curved and includes a distal face defined by the thickness of the distal end between the lumen and an exterior surface. The distal face may be flush with the bevel or chamfered. An inner corner angle between the distal face and the lumen is ?60° to reduce the chance of scratching the IOL as it passes out of the distal opening.

  • Patent number: 10993726
    Abstract: A blood flow restriction (BFR) exercise strap. The strap is configured with a coupling at a first end of an elastic band. A second free end of the band is releasably retained in the coupling by a lever arm that is biased in a closed configuration against a plurality of teeth carried on an interior surface of the base. The band has graduated indicia carried thereon for determining a constriction level applied by the band to a limb of the user. The graduated indicia allow the user to set a desired level of constriction on each of a left limb and a right limb to provide the user to develop bilateral symmetry of targeted muscle groups of the limbs.

  • Patent number: 10973640
    Abstract: A venous valve prosthesis includes a frame and a prosthetic valve coupled to the frame. With the venous valve prosthesis implanted in a vein, the prosthetic valve includes a closed configuration wherein an outer surface of the prosthetic valve is in contact with a wall of the vein around a circumference of the prosthetic valve to prevent blood from flowing past the prosthetic valve between the wall of the vein and the outer surface of the prosthetic valve. The prosthetic valve is configured to move to an open configuration such that at least a portion of an outer wall of the prosthetic valve partially collapses away from the wall of the vein in response to antegrade blood flow through the vein to enable blood flow between the outer surface of the prosthetic valve and the wall of the vein.

  • Patent number: 10966708
    Abstract: A stitching assembly includes upper and lower cradles, upper and lower needles, and first and second sutures supported by the upper and lower needles, respectively. The cradles move along a curved path in relation to the carriages between advanced and retracted positions. When each cradle is moved from the retracted position towards the advanced position, a stitch loop is formed when the respective needle is retracted. This process is repeated alternating between the first and second cradles with the upper and lower needles passing through the previous stitch loop formed by the other needle before passing through the tissue.

  • Patent number: 10966711
    Abstract: Disclosed herein are suture clip delivery devices that can be loaded with several flat, disk-shaped suture clips and can deploy the suture clips one after another onto respective sutures without reloading the device with additional suture clips. An exemplary device includes a handle portion with an actuation mechanism that is coupled to a shaft portion that holds and deploys the suture clips. The shaft portion includes a mandrel on which the suture clips are mounted and a retainer that restricts the suture clips from moving proximally when the actuation mechanism pulls the mandrel proximally, which causes a distal-most suture clip to slide off the mandrel and be deployed onto one or more suture. The mandrel and remaining suture clips can them move distally to prepare to deploy the next suture clip.

  • Patent number: 10966850
    Abstract: An implantable medical device deployment system is disclosed that employs both a sheath element and a constraint member to protect implantable medical devices during delivery in a body while providing simple, accurate, and reliable device deployment. The delivery system is configured so that loading and deployment forces are not directly related to device diameter, length, or design, thus allowing a more universal delivery system across various delivered device configurations and product lines. The deployment system can provide numerous benefits, include better protection for drug-coated implantable devices.
