Patent number: 10271870Abstract: The invention generally relates to intraluminal procedures, and, more particularly, to a contra-rotating cutting assembly for use with an atherectomy device to remove occlusive material from an occluded lumen, such as a blood vessel or other body lumen. The contra-rotating cutting assembly includes a rotatable housing having a distal end, an opposing proximal end and a lumen extending between the distal and proximal ends. The housing is configured to rotate about a longitudinal axis in a first direction. The cutting assembly further includes a rotatable cutter head positioned within at least a portion of the lumen of the housing and in coaxial alignment with the housing. The cutter head is configured to rotate about the longitudinal axis in a second direction opposite the first direction.Type: GrantFiled: June 30, 2016Date of Patent: April 30, 2019Assignee: VOLCANO CORPORATIONInventors: Torrey P Smith, Douglas E Rowe, Paul Quentin Escudero, August Christopher Pombo

Patent number: 10258343Abstract: A left atrial appendage occluder comprises an elastic closure disc, and a supporting structure connecting with the closure disc and being located on one side of the closure disc, with the supporting structure comprising a central end connecting with the closure disc and a plurality of interconnected and bent struts, wherein at least one anchoring thorn is set near the end of at least one strut with the anchoring thorn toward the closure disc. The left atrial appendage occluder has a stable structure, a good positioning and sealing effect on the cavity wall in the left atrial appendage, and it is easy to position repeatedly; it can also be recycled before separating from a conveyor. When in surgical operation, the left atrial appendage occluder can select the position area based on the actual shape and size of the patient's left atrial appendage, so the surgical risk is lowered.Type: GrantFiled: October 27, 2015Date of Patent: April 16, 2019Assignee: Lifetech Scientific (Shenzhen) Co.
