Filed:

May 10, 2011

Appl. No.:

13/104648

Inventors:

Hengchu Cao - Irvine CA, US
Brian Conklin - Orange CA, US
Paul Schmidt - Irvine CA, US
Grace Myong Kim - Garden Grove CA, US
James A. Davidson - San Juan Capistrano CA, US

International Classification:

A61F 2/24

US Classification:

623 211, 623 218, 623 241

Abstract:

Disclosed prosthetic valves can comprise a sewing ring configured to secure the valve to an implantation site. Some disclosed valves comprise a resiliently collapsible frame having a neutral configuration and a collapsed deployment configuration. Some disclosed frames can self-expand to the neutral configuration when released from the collapsed deployment configuration. Collapsing a disclosed valve can provide convenient access to the sewing ring, such as for securing the valve to the implantation site, as well as for the insertion of the valve through relatively small surgical incisions.

15/077739

Inventors:

- Gardena CA, US
Hoa Tran - Fountain Valley CA, US

International Classification:

H01M 2/20
H01M 2/26

Abstract:

Disclosed herein are battery systems for electric vehicles. A battery may include a plurality of electrochemical cells and an flexible circuit disposed above the electrochemical cells. The flexible circuit may be generally defined by a longitudinal and lateral axis. The flexible circuit may include a positive conductive path, a negative conductive path, at least one opening extending through the flexible circuit, at least one expandable positive interconnect capable of electrically connecting the positive path to a positive terminal of an electrochemical cell, and at least one expandable negative interconnect capable of electrically connecting the negative conductive path to a negative terminal of an electrochemical cell. The positive and negative interconnects may be expandable in at least the transverse direction and may extend from an edge of the at least one opening and terminate at a connection pad.

Disclosed prosthetic valves can comprise a sewing ring configured to secure the valve to an implantation site. Some disclosed valves comprise a resiliently collapsible frame having a neutral configuration and a collapsed deployment configuration. Some disclosed frames can self-expand to the neutral configuration when released from the collapsed deployment configuration. Collapsing a disclosed valve can provide convenient access to the sewing ring, such as for securing the valve to the implantation site, as well as for the insertion of the valve through relatively small surgical incisions. Examples of delivery systems and methods for deploying the valves exhibit reduced patient trauma.
