Patent number: 10335262Abstract: The invention provides an embolic protection device for removing emboli from a blood vessel in a patient's body. The device comprises an elongate host element, an embolic protection element having a collapsed configuration and an expanded configuration, and a flexible tether connected to a distal end of the host element and to a proximal portion of the embolic protection element. The tether allows the host element to move axially and laterally relative to the embolic protection element over a limited range of motion when the embolic protection element is in an expanded configuration. The embolic protection device has a landing zone of 4 cm or less.Type: GrantFiled: January 6, 2017Date of Patent: July 2, 2019Assignee: Covidien LPInventors: Richard S. Kusleika, Steven G. Zaver, Christopher G. Quinn

Patent number: 8167902Abstract: Catheter having a first elongate tubular body having a lumen, a second elongate tubular body having a lumen, and an elongate member. The elongate member joins the first and second elongate tubular bodies. The first tubular body is fixedly attached on the distal portion of the elongate member, and the second elongate tubular body is disposed on the elongate member is slidable along a portion of the elongate member. The second elongate tubular body can be in a first position so that the first and second tubular bodies are not adjacent to each other and can be in a second position so that the first and second tubular bodies are adjacent to each other. The catheter may have a locking mechanism that can lock the first and second elongate tubular bodies to each other so that the lumens of the first and second elongate tubular bodies form one continuous lumen.Type: GrantFiled: August 10, 2007Date of Patent: May 1, 2012Assignee: Tyco Healthcare Group LPInventors: Christopher G. Quinn, Sara K. Bakker, Steven G. Zaver, Kevin W. Anderson, Sengkham Sirivong
