  • Patent number: 10989771
    Abstract: The disclosure relates to a method for triggered acquisition of a measured data set by a magnetic resonance system, to a corresponding computer program, to a corresponding data memory and to the corresponding magnetic resonance system. In the method, a cyclical signal is detected, which describes a cyclical change in a target object to be imaged. Cycles are automatically identified in this cyclical signal. Furthermore, at least one property of the cyclical signal is automatically determined. It is then automatically determined whether triggering of a single measurement for acquisition of some of the measured data set is permitted in an identified cycle of the cyclical signal. This determination is made as a function of the at least one determined property of the cyclical signal and a specified reference value of an acquisition parameter.

    Abstract: Described is an apparatus for transcatheter detachment of a stent from a delivery device. A single-ended draw line with loops is inserted through a restraining hole in a glide and a release line is inserted through the loops. The single-ended draw line is thus prevented from pulling through the restraining hole while the release line is through the loops. The single-ended draw line is free to pass through the restraining hole after the release line is pulled out of the loops and thereafter pulled free of stent holes formed through a stent, thereby detaching the stent at a desired location.

  • Patent number: 10898356
    Abstract: A delivery device can provide sequential delivery of a plurality of intraluminal devices or tacks held in a compressed state on the delivery device. Delivery platforms on the delivery device can hold a tack in a compressed position and have a unique shape, such as a non-constant outer diameter, an hourglass shape, a tapered proximal half, ridges, dimples, etc. This unique shape can be positioned between annular pusher bands that may also be radiopaque markers. In some embodiments, the unique shape is provided by a sleeve of flexible material with the unique shape surrounding a harder inner shaft. Further, the annular pusher bands can be made of wire or sections of material to increase flexibility while remaining radiopacity. A tack deployment method can include alignment of radiopaque markers on the outer sheath and the tack to be deployed prior to deployment.

  • Patent number: 10893938
    Abstract: Numerous delivery devices for delivery of a stented prosthesis, such as a stented prosthetic heart valve. Various delivery devices include a capsule that is advanced proximally to retain the stented prosthesis, which is secured over an inner shaft assembly of the delivery device. The delivery device further includes a bumper or bumper assembly to provide a smooth transition of the capsule over the stented prosthesis. In some alternate disclosed embodiments, the bumper further serves to connect various elements of the inner shaft assembly. Additional embodiments include a bumper assembly arranged and configured to longitudinally expand and contract to substantially fill any open space as the capsule is retracted from the stented prosthesis, which prevents kinking in the capsule. Additional embodiments include proximal and/or distal bumpers for temporarily covering and smoothing the ends of the stented prosthesis as part of a delivery device that does not include a capsule.

  • Patent number: 10842630
    Abstract: Systems, devices, and methods for reducing regurgitation through an atrioventricular heart valve: i.e., the mitral valve and the tricuspid valve. The device includes a flexible anchor rail anchored in the tissue of the ventricle and an offset coaptation element on a catheter that rides over the anchor rail and is positionable between the valve leaflets. The proximal end of the coaptation catheter is fixed subcutaneously adjacent the subclavian vein. The coaptation element includes an inert covering over a foam interior, and is radially offset on the catheter so that the foam body projects away from the septal side of the valve to reduce or minimize deformation from contact with the septal wall of the ventricle. Markers on the coaptation element facilitate positioning in the desired rotational orientation during delivery and implant.
