Appl. No.:

10/327711

Inventors:

Michael V. Chobotov - Santa Rosa CA, US
Brian A. Glynn - Santa Rosa CA, US

Assignee:

Boston Scientific Santa Rosa Corp. - Santa Rosa CA

International Classification:

A61F 2/06
A61F 2/86

US Classification:

623 114, 623 135

Abstract:

This invention is a system for the treatment of body passageways; in particular, vessels with vascular disease. The system includes an endovascular graft with a low-profile delivery configuration and a deployed configuration in which it conforms to the morphology of the vessel or body passageway to be treated as well as various connector members and stents. The graft is made from an inflatable graft body section and may be bifurcated. One or more inflatable cuffs may be disposed at either end of the graft body section. At least one inflatable channel is disposed between and in fluid communication with the inflatable cuffs.

Appl. No.:

10/769532

Inventors:

Robert G. Whirley - Santa Rosa CA, US
James M. Shapiro - San Francisco CA, US

Assignee:

TriVascular, Inc. - Santa Rosa CA

International Classification:

A61F 2/06

US Classification:

623 113, 623 121, 623 139, 623 142

Abstract:

The present invention provides inflatable porous implants, such as grafts, stent-grafts, and bladders, as well as methods and kits for drug delivery. In particular, the grafts and stent-grafts of the present invention provide for the delivery of a therapeutic agent into a flow conduit in the body. The inflatable porous implants provide for direct delivery of larger, more precise dosages of drugs over longer administration periods into the body. Moreover, these inflatable porous implants are often flexible when inserted and have a low profile delivery configuration for easy placement. The implants of the present invention further provide a mechanical or structural function in addition to drug delivery in a single integrated structure.

International Classification:

G06G 7/48

US Classification:

703 7, 703 2, 703 11

Abstract:

A system and method of developing better-designed medical devices, particularly cardiovascular stents and endovascular grafts. The system comprises a geometry generator, a mesh generator, a stress/strain/deformation analyzer, and a visualization tool. In one embodiment, the geometry generator receives three-dimensional volumetric data of an anatomical feature and generates a geometric model. The mesh generator then receives such geometric model of an anatomical feature or an in vitro model and a geometric model of a candidate medical device. In another embodiment, the mesh generator only receives a geometric model of the candidate medical device. Using the geometric model(s) received, the mesh generator creates or generates a mesh or a finite element model. The stress/strain/deformation analyzer then receives the mesh, and the material models and loads of that mesh. Using analysis, preferably non-linear analysis, the stress/strain/deformation analyzer determines the predicted stresses, strains, and deformations on the candidate medical device.
