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: 20080255655Abstract: An implant delivery catheter enables permanent modification of the implant length in the vicinity of the treatment site prior to radial expansion thereof. The implant is releasable carried between inner and outer tubular members of the delivery catheter which, upon repositioning relative to one another using an actuator mechanism, impart any of tensile, compressile or torquing forces to the implant causing permanent modification of the implant length. In one embodiment, the circumference of the implant is substantially similar both before and after modification of the implant length. In another embodiment, the implant includes a plurality of strut sections interconnected by bridges which are capable of the deformation along the longitudinal axis of the implant.Type: ApplicationFiled: April 8, 2008Publication date: October 16, 2008Applicant: EV3 Peripheral, Inc.Inventors: Rich Kusleika, Doug Duchon, Joe Tatalovich

Patent number: 7323189Abstract: A method for forming liquid coatings for medical devices such as stents and angioplasty balloons is provided. The liquid coatings can be made from biodegradable materials in liquid, low melting solid, or wax forms, which preferably degrade in the body without producing potentially harmful fragments. The liquid coatings may also contain biologically active components, which are released from the coatings through diffusion from the coatings and the degradation of the coatings.Type: GrantFiled: December 21, 2001Date of Patent: January 29, 2008Assignee: eV3 Peripheral, Inc.Inventor: Chandrashekhar Pathak

Patent number: 7125414Abstract: An emboli filter for deployment in a body lumen to capture emboli entrained in a fluid flowing through the lumen includes a flexible elongated member sized to be passed through the lumen. A filter media is carried on and substantially surrounding the elongated member. The filter media has a first end secured to the elongated member adjacent the distal end. A second end of the filter media has a periphery movable toward and away from the elongated member. Opposing internal surfaces of the filter media define a volume into which emboli may flow through the second end when the periphery is moved away from the elongated member. The emboli are trapped within the volume when the periphery is moved toward the elongated member. An actuator moves the periphery toward and way from the elongated member. The actuator includes a plurality of elastic loops. The loops are biased to an open loop configuration with the loops urging the periphery away from the elongated member.Type: GrantFiled: January 2, 2003Date of Patent: October 24, 2006Assignee: ev3 Peripheral, Inc.Inventors: Victor R. Blackledge, Charles H. Whatley, Jr., Benjamin E. Morris, Todd A. Hall, William A. Reuss, Jr.
