Patent number: 8298160Abstract: Apparatus for use in deploying medical devices. The apparatus includes a wire having a diameter such that the wire can appropriately be used with either a corresponding over-the-wire configured catheter or a rapid-exchange configured catheter. The wire has a location at which it can be easily fractured, when desired, in order to convert the length of the wire from a length for use in an over-the-wire configuration to a rapid-exchange configuration.Type: GrantFiled: March 14, 2002Date of Patent: October 30, 2012Assignee: EV3 Inc.Inventors: John C.

Publication number: 20110288633Abstract: A intraluminal stent comprises a reticulated tube having an un-deployed diameter and expandable to an enlarged diameter. The tube includes a structural beam extending between first and second ends. The structural beam changes from a first geometry to a second geometry when the tube changes from the un-deployed diameter to the enlarged diameter. The structural beam includes first and second longitudinal elements each extending at least partially between the first and second ends and with a spacing between the first and second elements. Each of said first and second elements changes from the first geometry to the second geometry when the tube changes from the un-deployed diameter to the enlarged diameter for the spacing to remain substantially unchanged as the tube changes from the un-deployed diameter to the enlarged diameter.Type: ApplicationFiled: August 5, 2011Publication date: November 24, 2011Applicant: EV3 PERIPHERAL, INC.Inventor: Paul J.

Publication number: 20110130785Abstract: A collapsible medical device for use, e.g., as a vascular filter. The device includes a mandrel having a distal end and a stop spaced proximally of the distal end. A proximal length of the mandrel extends proximally of the stop and a distal length of the mandrel extends distally of the stop. A functional element (e.g., a vascular filter) has a radially expandable body and includes a proximal slider and a distal slider. The proximal and distal sliders are slidable along the mandrel independently of one another such that the distance between the proximal slider and distal slider can be varied to effect different configurations of the functional element. In one method of using such a device, the functional element is urged distally to a treatment site by urging the mandrel distally.Type: ApplicationFiled: February 9, 2011Publication date: June 2, 2011Applicant: EV3 INC.Inventor: Richard S.

Patent number: 7927784Abstract: A debulking catheter comprising a tissue debulking assembly for removing a continuous strand of material from a body lumen. Catheters of the present invention generally include a catheter body having proximal and distal portions and a tissue debulking assembly disposed at least partially within the distal portion. The tissue debulking assembly is radially movable to expose at least a portion of the assembly through a window on the catheter body. The catheter is advanced transluminally through the body lumen to contact material in the body lumen and remove a plane of continuous material that has a length that is typically longer than a length of the window on the catheter. The continuous material may be directed into a collection chamber. Thereafter, the material may be removed from the collection chamber and preserved or tested.Type: GrantFiled: January 10, 2006Date of Patent: April 19, 2011Assignee: EV3Inventor: John B. Simpson

Patent number: 7887562Abstract: A tissue opening occluder comprising first and second occluder portions, each occluder portion including a frame structure and an attachment structure to attach one portion to the other portion. The frames may be utilized to constrain the tissue between the two portions enough to restrict the significant passage of blood therethrough. The frame portions may be covered by a fabric suspended from a perimeter thereof. The occluder portions are conjoined at least one point on each portion.Type: GrantFiled: October 29, 2007Date of Patent: February 15, 2011Assignee: EV3 Endovascular, Inc.Inventors: Michelle M.
