Patent number: 10080607Abstract: An ablation catheter comprises an elongated catheter body; at least one ablation element disposed in a distal portion which is adjacent the distal end of the catheter body; an illumination optical element disposed in the distal portion, the illumination optical element being light-transmissive to emit light from the illumination optical element to the targeted tissue region; and a collection optical element disposed in the distal portion, the collection optical element being light-transmissive to collect one or more of returned, backscattered or newly excited light from the targeted tissue region. The illumination or excitation optical element and the collection optical element are axially spaced from one another and axially optically isolated from one another within the distal portion to substantially prevent light from traveling between the illumination optical element and the collection optical element along a path within the distal portion.Type: GrantFiled: March 6, 2015Date of Patent: September 25, 2018Assignee: St. Jude Medical, LLCInventors: John W.

Patent number: 10058422Abstract: A stent for use in a prosthetic heart valve has a plurality of expandable and collapsible closed cells, a portion of which form an annulus section adapted for placement within the annulus of the native heart valve. Anchor features of the stent residing within at least some closed cells are adapted to engage tissue of the heart, including native valve leaflets, the sinotubular junction, or another implanted device when the prosthetic valve is implanted in the heart. The anchor features may help to retain the prosthetic valve in position, without interfering with the opening and closing of the valve leaflets. Furthermore, the anchor features may be configured to allow the stent to be resheathed into a delivery device after the portion of the stent with the anchor feature has expanded out of the delivery device.Type: GrantFiled: February 3, 2017Date of Patent: August 28, 2018Assignee: St. Jude Medical, LLCInventor: Peter N. Braido

Patent number: 10028830Abstract: A delivery device for a collapsible prosthetic heart valve includes a support shaft around which a compartment for the valve is defined, a distal sheath adapted to selectively cover and uncover the compartment and the valve, and a marker cage having a collapsed condition when the distal sheath covers the compartment and an expanded condition when the compartment is uncovered. The marker cage includes at least one rib having a radiopaque marker for determining the positioning of the valve as it is deployed. The valve may be assembled around the marker cage so that the marker cage does not interfere with the radial expansion of the valve during deployment.Type: GrantFiled: May 18, 2016Date of Patent: July 24, 2018Assignee: St. Jude Medical, LLCInventor: Huisun Wang

Publication number: 20180200053Abstract: A prosthetic aortic valve includes an annular, annulus inflow portion that is designed to reside in or near the patient's native aortic valve annulus, and an annular, aortic outflow portion that is designed to reside in the patient's aorta downstream from at least a portion of the valsalva sinus. The annulus inflow portion and the aortic outflow portion are connected to one another by a plurality of connecting struts that are confined to regions near the commissures of the patient's native aortic valve. The connecting struts are designed to bulge out into the valsalva sinus to help anchor the prosthetic valve in place. The valve is circumferentially collapsible to a relatively small diameter for less-invasive delivery into the patient. The valve circumferentially expands to a larger operational diameter when deployed at the implant site.Type: ApplicationFiled: March 16, 2018Publication date: July 19, 2018Applicant: St. Jude Medical, LLCInventor: Yousef F.

Patent number: 9820851Abstract: A prosthetic heart valve is designed to be circumferentially collapsible for less invasive delivery into the patient. At the implant site the valve re-expands to a larger circumferential size, i.e., the size that it has for operation as a replacement for one of the patient's native heart valves. The valve includes structures that, at the implant site, extend radially outwardly to engage tissue structures above and below the native heart valve annulus. These radially outwardly extending structures clamp the native tissue between them and thereby help to anchor the prosthetic valve at the desired location in the patient.Type: GrantFiled: April 16, 2015Date of Patent: November 21, 2017Assignee: St. Jude Medical, LLCInventor: Peter N.
