  • Patent number: 10137019
    Abstract: The medical instrument includes: a first rod; a second rod which extends along the first rod; a longitudinal center line defined by the rods; and a manipulator. The manipulator includes a plurality of fingers, each with a first finger end and a second finger end. The second finger ends are free ends. The first finger ends are supported on the second rod in such a way that the fingers are operable, by moving the second rod in relation to the first rod, in order to be displaced from a first position to a second position. The distance from the free ends of the fingers to the longitudinal center line in the first position is different compared with the second position. A stent, a ring prosthesis and a prosthesis device are also described.

  • Patent number: 10130821
    Abstract: An assembly for tethering a medical device to a delivery catheter includes a tether, a collet, and a spring-biased holding element that is coupled to a distal end of the tether and that extends around the collet, being moveable between first and second positions. At the first position, corresponding to the spring bias thereof, the holding element prevents fingers of the collet, which are configured to grip a proximal end of the device, from opening; at the second position, the collet fingers are allowed and/or caused to open. The assembly is coupled to a tubular member of the catheter, and, when the tethering assembly abuts a distal end of the catheter tubular member, a pull force applied to a proximal end the tether, which extends out from a proximal opening of the catheter, moves the holding element from the first position to the second position.

  • Patent number: 10123871
    Abstract: An implant capsule (10) and an implant delivery system are disclosed. The implant capsule (10) includes, sequentially from a proximal end to a distal end, a flexural section (102, 102a-102e), a reinforcement section (101, 101a-101e) and a radiopaque reinforcement ring (104a-104e). The reinforcement section (101, 101a-101e) has higher strength than the flexural section (102, 102a-102e). The implant delivery system includes the implant capsule (10). The implant capsule (10) can ensure the implant to be deployed in a coaxial condition and prevent over-expansion due to large expansion forces exerted by a stent of the implant.

  • Patent number: 10098644
    Abstract: Methods and systems for regulating aortic regurgitation during aortic valve replacement or repair procedures utilize a temporary aortic valve (TAV) catheter and a controller. The temporary aortic valve catheter has an expandable occlusion device which can partially occlude the aortic lumen during ventricular diastole with a lesser occlusion during ventricular systole. Exemplary balloon structures include multiple, independently inflatable balloons which are inflated in synchrony with the cardiac cycle by the controller. By controlling aortic regurgitation, the repair or replacement protocols can be conducted with less interference from blood flow.

  • Patent number: 10098770
    Abstract: Devices, systems, and methods for implanting prostheses in the body lumens rely on tacking or anchoring the prostheses with separately introduced fasteners. After initial placement, a fastener applier system is introduced within the expanded prostheses to deploy a plurality of fasteners to at least one prosthesis end. The fasteners are usually helical fasteners which are releasably restrained on the fastener driver, and are delivered by rotation of the fastener driver. The fasteners may be applied singly, typically in circumferentially spaced-apart patterns about the interior of at least one end of the prosthesis. A lumen extension or lumens may be coupled to the prosthesis to extend the reach of the prosthesis within the implantation site. Fasteners may also be applied to the lumen extensions.
