Patent number: 7371249Abstract: The present invention is a temporary intraluminal filter guidewire for use during interventional procedures, such as angioplasty or stent deployment. A braided filter is mounted near the distal end of a steerable guidewire, which guides a therapeutic catheter. An actuator rod slides over the guidewire and is removably connected to the filter. The rod controls relative displacement of the filter ends, causing transformation of the filter between a deployed configuration and a collapsed configuration. Wire having enhanced radiopacity is included in the filter to provide visualization under fluoroscopy.Type: GrantFiled: February 8, 2005Date of Patent: May 13, 2008Assignee: Medtronic Vascular, Inc.Inventors: Nareak Douk, Nasser Rafiee, David S.

The rod controls relative displacement of the filter ends, causing transformation of the filter between a deployed configuration and a collapsed configuration. In several embodiments, the guidewire distal to the filter has a fixed tip length. Other embodiments of the invention include a mechanism for damping longitudinal movement between the distal and proximal ends of the filter.Type: GrantFiled: March 10, 2004Date of Patent: June 27, 2006Assignee: Medtronic Vascular, IncInventors: Nareak Douk, Nasser Rafiee, David S.

Patent number: 6989027Abstract: The percutaneously delivered temporary valve assembly of the present invention, and method of using the same, provides an elongate element and a temporary valve disposed on the elongate element. The temporary valve can comprise struts and a membrane attached to the struts. The elongate element can include at least one lumen. The percutaneously delivered temporary valve assembly can be used to replace an aortic valve by locating a temporary valve in a patient's ascending aorta; deploying the temporary valve; removing the native aortic valve past the temporary valve; implanting the prosthetic aortic valve past the temporary valve; collapsing the temporary valve; and removing the temporary valve from the patient. The temporary valve can be sized to the patient and can be left in place while the prosthetic aortic valve heals in.Type: GrantFiled: April 29, 2004Date of Patent: January 24, 2006Assignee: Medtronic Vascular Inc.Inventors: Jeffrey W.

Publication number: 20040267357Abstract: The cardiac valve modification device of the present invention provides a catheter; an injection assembly disposed on the catheter, the injection assembly having lobes, and a neck disposed between the lobes; and at least one injector operably disposed at the neck. The injector can be an injection barb, made of a biodegradable material including a therapeutic agent, and deposited in the valve annulus, or an injection needle, which delivers a therapeutic agent to the valve annulus. The therapeutic agent can be a pro-fibrotic growth factor or a bulking agent. The cardiac valve modificaton method comprises inserting an injection catheter to the valve annulus; and injecting a therapeutic agent into the valve annulus with the injection catheter. The procedure can be repeated to modify the cardiac valve in a series of steps.Type: ApplicationFiled: April 28, 2004Publication date: December 30, 2004Inventors: Jeffrey W. Allen, David S.
