  • Publication number: 20250281183
    Abstract: A left atrial appendage (“LAA”) occluder may include a proximal disk configured to cover an ostium of the LAA, a distal lobe configured to be received within a cavity of the LAA, and a connecting member connecting the proximal disk to the distal lobe. The occluder may include first and second groups of stabilizing members having first and second engagement features, respectively, configured to engage tissue surrounding the LAA when the occluder is implanted. In an unbiased condition of the occluder, the distal lobe may have an axial length extending between a proximal face and a distal face of the distal lobe. The second engagement features may be positioned at least 33% of the axial length beyond the proximal face of the distal lobe, and the first engagement features may be positioned distal to the second engagement features.

  • Patent number: 11759229
    Abstract: Rotational atherectomy devices and systems can remove or reduce stenotic lesions in blood vessels by rotating an abrasive element within the vessel. The abrasive element can be attached to a distal portion of an elongate flexible drive shaft that extends from a handle assembly. In particular embodiments, the handle assembly includes a compressed gas driven turbine member that drives rotation of the drive shaft. The turbine member can be rotatably attached to a carriage that is longitudinally translatable in relation to a housing of the handle assembly. The handle assembly can include a latch mechanism that when actuated allows the carriage to translate to a proximal-most position. While the carriage is in the proximal-most position, an open pathway is created so that a guidewire can be slidably passed through the handle assembly and a lumen of the drive shaft.

  • Patent number: 11471571
    Abstract: Embodiments of a canister for a negative pressure wound therapy systems and methods for operating the systems are disclosed. In some embodiments, the canister includes a receptacle for receiving wound exudate. A filter stack is interposed between the receptacle and the pump assembly and provides a fluid flow path therebetween. The flow path is more easily navigable by gas than by liquid, thereby allowing the pump assembly to apply a negative pressure to the canister without aspirating wound exudate into filters housed within the filter stack.

  • Patent number: 10820995
    Abstract: A delivery device usable to deliver an inverting implant is provided that includes a positioning mechanism that automatically initiates the inversion process once a predetermined length of the implant has exited a delivery catheter. The positioning mechanism allows the implant to be safely and accurately deployed with reduced operator experience and in a greater variety of target locations.
