Patent number: 11759229Abstract: 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.Type: GrantFiled: April 10, 2023Date of Patent: September 19, 2023Assignee: Cardio Flow, Inc.Inventors: Cassandra Ann Piippo Svendsen, Charles Anthony Plowe, Albert Selden Benjamin, Paul Joseph Robinson, Evan Leingang

Patent number: 11471571Abstract: 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.Type: GrantFiled: April 17, 2018Date of Patent: October 18, 2022Assignee: Smith & Nephew, Inc.Inventors: Lars Runquist, Evan Leingang, Richard A. Thompson, II, Thom Tedham
