Publication number: 20210370021Abstract: The present invention includes an embolic protection device comprising a catheter having a self-expanding embolic filter that is disposed around the catheter proximal to a distal portion, wherein the embolic filter comprises a frame, and the frame defines an opening of the embolic filter that faces the distal end of the catheter; a deployment mechanism that is disposed around at least a portion of the catheter, wherein the deployment mechanism is longitudinally movable with respect to the catheter, the deployment mechanism is configured to contain the embolic filter in a collapsed configuration, and the embolic filter is configured to self-expand upon the longitudinal retraction of the deployment mechanism; and a wire coupled to the frame for expanding the size or diameter of the embolic filter opening.Type: ApplicationFiled: June 17, 2021Publication date: December 2, 2021Inventors: William M. Merhi, Andy Black, Mark Carlson, Josh Greene, Kelly Jensen, Andy Leopold, Ben Rockwell

Patent number: 8948848Abstract: Embolic protection devices and methods for capturing embolic debris. An embolic protection device includes a pigtail catheter having a lumen for housing a guidewire. The distal portion of the catheter has one or more apertures in fluid communication with the lumen and one or more radiopaque markers on the distal-most section. The device includes a self-expanding filter coupled to a side of the catheter and a movable outer sheath surrounding the catheter. The outer sheath holds the filter in a collapsed configuration when surrounding the filter. The outer sheath is proximally retracted to deploy the filter. A method of capturing embolic debris includes inserting a guidewire into a body lumen, tracking the device over the guidewire, retracting the guidewire, positioning the device using the radiopaque marker, retracting the outer sheath and deploying the filter, performing a procedure, and advancing the outer sheath to recapture the filter.Type: GrantFiled: December 5, 2011Date of Patent: February 3, 2015Assignee: Innovative Cardiovascular Solutions, LLCInventor: William M Merhi
