Patent number: 10751522Abstract: A bi-directional cannula for perfusing blood in two directions. The cannula has a distal opening in fluid communication with a cannula first lumen. The cannula has a secondary opening proximal of the distal opening, and may include a movable tubular extension selectively extendable from the cannula via the secondary opening. The tubular extension may be in fluid connection with the cannula first lumen and/or a cannula second lumen. The tubular extension may have distal and/or side openings, with the openings providing antegrade fluid perfusion. The cannula second lumen may be separate from the first lumen, so that perfusion can be selectively provided to just the cannula distal opening, just the secondary opening/tubular extension, or simultaneously to both the distal opening and secondary opening/tubular extension.Type: GrantFiled: May 29, 2018Date of Patent: August 25, 2020Assignee: Edwards Lifesciences CorporationInventors: Thomas Walther, Mark M. Dehdashtian, Teodoro S. Jimenez, Norma A. Garcia

Patent number: 10667821Abstract: Embodiments of aortic occlusion devices are described herein that include radially expandable and collapsible proximal and distal end portions, such as annular self-expanding stents or frames, that are configured to radially expand within an aorta to secure the device within the aorta. The devices can also include a catheter extending axially between the distal end portion and the proximal end portion and a porous covering, or filter, positioned around the catheter and between the proximal end portion and the distal end portion and configured to filter emboli from blood flowing into upper-body arteries. The device can further include a one-way valve positioned at or adjacent to the distal end portion of the device and configured to restrict retrograde blood flow through the device toward the heart.Type: GrantFiled: November 16, 2018Date of Patent: June 2, 2020Assignee: Edwards Lifesciences CorporationInventors: Mark M. Dehdashtian, Teodoro S. Jimenez, Nathan Satter, Fabian Daniel Schroeder, Raffaele Mazzei, Jeff Kosmoski, Shahram Zamani, Adam J. Yestrepsky

Publication number: 20200129289Abstract: A collapsible device, such as an annuloplasty ring or prosthetic heart valve, is configured to be collapsed prior to being introduced into a patient via minimally-invasive access points such as port holes or intercostal incisions. A holder is configured to hold the collapsible device, and to selectively collapse the device for introduction into the patient and then re-enlarge the device at the desired deployment site. Collapsible devices include devices that can hingedly fold about hinge lines, and devices that can elongate to form substantially spiral forms with reduced diameters.Type: ApplicationFiled: December 23, 2019Publication date: April 30, 2020Inventors: Teodoro S.

Publication number: 20200107947Abstract: Delivery systems for expandable elements, such as stents or scaffolds having spikes, flails, or other protruding features for penetrating target tissue and/or delivering drugs within a human patient are described along with associated methods for using such systems. The delivery systems can be provided with a stent that is positioned over an inflatable balloon for expansion and delivery of the stent to a target delivery location. By positioning the stent over and about the inflatable balloon, the stent is ready to be expanded by the balloon immediately upon unsheathing with respect to the outer shaft. Additionally or alternatively, a stent can be positioned in an axially offset arrangement with respect to a balloon to reduce the need for space required by overlapping components.Type: ApplicationFiled: October 4, 2019Publication date: April 9, 2020Inventors: Teodoro S. Jimenez, JR., Patrick Lo, John Fulkerson, Isa Rizk, Francisco Aguayo, Jihad Ali Mustapha, Gary Ansel

Publication number: 20200100896Abstract: A delivery system and method for delivering a prosthetic heart valve to the aortic valve. The system includes a delivery catheter having a steering mechanism thereon for delivering a balloon-expandable prosthetic heart valve to the aortic valve through an introducer passing into the left ventricle through its apex. The introducer may have a more floppy distal section than a proximal section to reduce trauma to the heart wall while preserving good operating field stability. The delivery catheter includes a deflecting segment just proximal to a distal balloon to facilitate positioning of the prosthetic heart valve in the proper orientation. A trigger in a catheter handle may be coupled to a deflection wire that actuates the deflecting segment, while a slider in the handle controls retraction of a valve pusher. The prosthetic heart valve may be installed over the existing calcified leaflets, and a pre-dilation valvuloplasty procedure may also be utilized.Type: ApplicationFiled: December 4, 2019Publication date: April 2, 2020Inventors: Teodoro S. Jimenez, Walter Lee, Mark M. Dehdashtian, Kristopher J. Yee

Publication number: 20190201219Abstract: Expandable elements having drug-delivery features and associated systems and methods are disclosed herein. In one embodiment, a drug-eluting stent includes a radially expandable cylindrical frame having a plurality of struts. The frame is transformable between a low-profile delivery state and an expanded deployed state. A plurality of drug-delivery features are carried by one of the struts and configured to deliver a drug to a treatment site within the patient or piercing through the tissue wall to break the constricting of the vessel wall inwardly. When the frame is in the expanded state within a body lumen of the patient, the drug-delivery features extend radially outwardly away from the strut and are configured to engage and, in some arrangements, pass through a wall of the body lumen.Type: ApplicationFiled: March 6, 2019Publication date: July 4, 2019Inventors: John Fulkerson, Isa Rizk, Jihad Ali Mustapha, Teodoro S.
