US Patent:

7399291, Jul 15, 2008

Filed:

Dec 1, 2005

Appl. No.:

11/291758

Inventors:

Minh Vo - Sugar Hill GA, US
Cory Anderson - Alpharetta GA, US

Assignee:

Syntheon, LLC. - Miami FL

International Classification:

A61F 7/12
A61F 7/00
A61M 29/00

US Classification:

604 9601, 604113, 607104

Abstract:

A catheter for treatment of chronic total occlusions includes an occlusion breach device, a catheter body made of a temperature-dependent softening, shape-memory, thermoplastic polymer having a first flexible state and a second stiff state. The catheter body has a heat transfer conduit and a conduit for slidably receiving the breach device. A heat-transferring device selectively changes a temperature of the heat transfer conduit to, thereby, change stiffness of the catheter body between the two states. To treat a CTO with the catheter, it is warmed above the glass-transition temperature and below the melting-temperature to make the catheter flexible. The catheter has a shape when inserted at the occlusion site and is cooled to, thereby, stiffen. Breaching of the occlusion is assisted with the stiff catheter. The catheter is removed by warming the polymer.

Appl. No.:

12/806541

Inventors:

Minh Vo - Sugar Hill GA, US

International Classification:

A61J 1/22

US Classification:

604407

Abstract:

Technologies are generally described for the storage of biologics and other fluid materials while maintaining aseptic conditions. A system may include a storage body providing a reservoir for containing the materials. A cap may couple to the storage body forming a fluid-tight seal. A port may be provided for transferring the materials. A seal, or valve, may be provided within the port. The seal may be configured to close off the reservoir unless acted upon to release the materials through the port. A movable member may make up part of the storage body. The movable member may be configured to change a reservoir volume of the storage body in response to changes in a volume of the materials. The reservoir may become smaller as the materials are released. Multi-dose volumes of fluid materials may be stored for repeated access with reduced risk of contamination and reduction in shelf life.

Abstract:

Systems and methods can support generation of a full-thickness, human skin organ from tissue culture expanded cells. Human dermal and epidermal progenitor cells can be isolated from human tissues. Isolated cells may be cultured as epidermal cells while other isolated cells may be separately cultured as dermal cells. The cultured epidermal cells and dermal cells may be combined for co-culturing. The co-cultured cells may be suspended within a slurry. The co-cultured cells may be implanted onto a recipient organism for generation of a full-thickness skin organ comprising fully cycling hair follicles, adipose tissue, and other skin organ structures.
