  • 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.
