System And Method For Locating Medical Devices In Vivo Using Ultrasound Doppler Mode
US Patent:
2010030, Dec 2, 2010
Filed:
May 27, 2010
Appl. No.:
12/789156
Inventors:
Francis G. Duhay - Irvine CA, US
David Zollinger - Irvine CA, US
David Zollinger - Irvine CA, US
Assignee:
EDWARDS LIFESCIENCES CORPORATION - Irvine CA
International Classification:
A61B 8/00
US Classification:
600424
Abstract:
A system for locating a medical device in vivo includes an ultrasound scanner having a scan head and being capable of operating in a 3D Doppler mode, a medical device having a distal end configured to be inserted in vivo, and a vibratory element coupled to the medical device to induce vibrations in the first distal end. When the scan head is positioned over the distal end inserted in vivo to obtain scan data of the tissue volume, the ultrasound scanner is configured to generate 3D Doppler data in the form of a plurality of slices from the scan data and to identify a location of the distal end within the slices based upon localized data within one of the slices meeting predetermined criteria.
Intracardiac Sheath Stabilizer
US Patent:
2011002, Feb 3, 2011
Filed:
Jul 28, 2010
Appl. No.:
12/845584
Inventors:
Kristopher Yee - San Francisco CA, US
Francis G. Duhay - Irvine CA, US
Francis G. Duhay - Irvine CA, US
Assignee:
EDWARDS LIFESCIENCES CORPORATION - Irvine CA
International Classification:
A61B 1/32
US Classification:
600231
Abstract:
A surgical stabilizer for use with a surgical site retractor has a base, a bendable arm, and a distal cuff adapted to resiliently hold a tube of an elongated port-access device. The cuff may have a body defining a partial enclosure within which is held a highly flexible gasket having a slit for resiliently receiving the tube. The surgical site retractor may have a collapsible ring and a flexible outer portion attached thereto, the ring being sized to pass through an intercostal incision and expand therein under adjacent ribs to prevent removal, and the flexible outer portion extending out of the incision and drawing over the stabilizer base to mutually secure the retractor and base. The port-access tube may be for a heart valve delivery system using an elongated port-access device for transapically delivering a prosthetic heart valve to the aortic valve annulus. A method involves partly installing the surgical site retractor, anchoring the base of the stabilizer with the flexible outer portion, deploying the port-access tube from outside the body through the incision and through a puncture in the heart wall, and resiliently capturing a tube of the port-access within the partial enclosure of the stabilizer cuff. A second bendable arm on the base having a clip may be used to hold still a proximal end of the port-access device.
Devices, Systems And Methods For Accurate Positioning Of A Prosthetic Valve
US Patent:
2012027, Oct 25, 2012
Filed:
Mar 28, 2012
Appl. No.:
13/432901
Inventors:
Francis G. Duhay - Irvine CA, US
David L. Zollinger - Irvine CA, US
David L. Zollinger - Irvine CA, US
Assignee:
EDWARDS LIFESCIENCES CORPORATION - Irvine CA
International Classification:
A61F 2/24
US Classification:
623 211
Abstract:
The invention is a system and method for accurately positioning a prosthetic valve such as a prosthetic heart valve at a desired position for deployment. The invention includes extendable positioning elements which provide tactile feedback to a user to confirm proper positioning of the catheter with respect to the native valve annulus. During delivery, the extendable positioning elements lie against the catheter, over the prosthetic valve and expandable balloon, providing a low profile for advancing the catheter to the desired treatment location via small passages such as body lumens. Prior to valve deployment, the positioning elements are extended and brought into contact with tissue of the native annulus to confirm the proper positioning of the delivery system and prosthetic valve.
Approaches To Venous Occlusion For Embolus Management
US Patent:
8449565, May 28, 2013
Filed:
Jul 21, 2011
Appl. No.:
13/188408
Inventors:
Francis Duhay - Irvine CA, US
International Classification:
A61B 17/08
US Classification:
606158, 606194, 606200, 128898, 600504
Abstract:
The invention provides a method and system for transiently occluding a vein that is downstream of an organ such as the brain, where the occlusion increases blood pressure within the vein, and where the increased pressure stimulates a reflex that reduces entry of emboli into that organ.
