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:

Examples of the present disclosure describe systems and methods for scene reconstruction from bursts of image data. In an example, an image capture device may gather information from multiple positions within the scene. At each position, a burst of image data may be captured, such that other images within the burst may be used to identify common image features, anchor points, and geometry, in order to generate a scene reconstruction as observed from the position. Thus, as a result of capturing bursts from multiple positions in a scene, multiple burst reconstructions may be generated. Each burst may be oriented within the scene by identifying a key frame for each burst and using common image features and anchor points among the key frames to determine a camera position for each key frame. The burst reconstructions may then be combined into a unified reconstruction, thereby generating a high-quality reconstruction of the scene.
