Publication number: 20180272116Abstract: 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: ApplicationFiled: May 29, 2018Publication date: September 27, 2018Inventors: Thomas Walther, Mark M. Dehdashtian, Teodoro S. Jimenez, Norma A. Garcia

Publication number: 20180042722Abstract: 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: October 26, 2017Publication date: February 15, 2018Inventors: Teodoro S.

Publication number: 20170319341Abstract: 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: July 27, 2017Publication date: November 9, 2017Applicant: Edwards Lifesciences CorporationInventors: Teodoro S. Jimenez, Walter Lee, Mark M. Dehdashtian, Kristopher J. Yee

Publication number: 20170196717Abstract: 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 27, 2017Publication date: July 13, 2017Inventors: John Fulkerson, Isa Rizk, Jihad Ali Mustapha, Teodoro S. Jimenez, JR.
