Title: Delivery catheter and graft for aneurysm repair
Inventor: ORTH GEOFFREY A
IPC: A61F2/958
Filed: 1995-11-08
Granted: 2009-05-19
Abstract: This invention provides a graft delivery system and methods for its use comprising a prosthetic graft (12) secured to an expandable anchoring member, such as a stent (13), by a butt-joint attachment means (21) to minimize the system's profile. The delivery system employs a catheter (11) with a relatively small diameter shaft (14) for flexibility and a relatively large diameter (14) delivery base (17) for supporting expansion of the anchoring member. The butt-joint attachment means comprises any means suitable to secure the graft to the anchoring member when deployed within the patient's vasculature and allows the anchoring member and graft to expand during deployment. In a preferred embodiment, the delivery system is configured so that the expansion of the anchoring member pulls the distal end of the graft over the proximal end of the anchoring member and the final expansion of the anchoring member seals the distal end of the graft (12) between the proximal end of the anchoring member and the vessel (20). One preferred method of use is to deploy a second anchoring member (31) coaxially within the already deployed first anchoring member and graft assembly, overlapping at least the distal end of the graft in order to further secure the graft and minimize flow by.

Abstract: In an exemplary embodiment, a server system stores a plurality of textual scripts in a database server in association with a plurality of contractor actions. Each of the textual scripts comprises an alert notifying the contractor of an obligation to perform the associated contractor action. The server system generates a plurality of deadlines by which the contractor is required to perform the contractor actions, and provides a user interface that allows a user to submit a plurality of notices of completion for the contractor actions. If a particular notice of completion is not submitted by the deadline for the contractor action, the server system selects the textual script associated with the contractor action, converts the textual script to a voice message, and initiates transmission of the voice message to the contractor via a telephone network.

Abstract: A vertically directed dryer unit (10) for compressed air, comprising a dryer cartridge (22) which, together with a housing (16, 18, 20), defines an inlet head area (92) and an outlet head area (72). A plurality of hollow membrane fibers (30) extend inside the cartridge between the two head areas, the wall material thereof being more permeable with respect to water vapor than air. An outlet valve (90) is provided between the outlet head area (72) and an outlet (74) of the drier unit. Said valve only opens when the pressure in the outlet head area (72) produces sufficient pressure for the provision of purging air.  The purging air is fed to the outer surface of the membrane fibers (30) via a throttle element (70).
