US Patent:

6576008, Jun 10, 2003

Filed:

Jul 6, 2001

Appl. No.:

09/899112

Inventors:

Marian A. Devonec - Miribel, FR
Robert F. Rioux - Ashland MA
Kimberly A. Paddock - Newton MA
John W. Lehman - Wayland MA

Assignee:

SciMed Life Systems, Inc. - Maple Grove MN

International Classification:

A61F 206

US Classification:

623 116, 623 2364

Abstract:

A stent device and methods for inserting and removing a stent to and from an anatomical tract of a living being. The stent includes a distal segment and a proximal segment joined by a flexible connection structure. The stent is inserted using components comprising a delivery assembly such that the stent proceeds through the anatomical tract and seats the flexible connection structure of the stent in a natural constricting structure of the anatomical tract. The flexible quality of the connection structure permits the natural constricting functions of the anatomical tract to occur. The natural closure of the anatomical constricting structure stops the flow of fluid, for example, from a target organ which indicates that the stent is properly placed within the anatomical tract.

US Classification:

15345, 152101, 15304

Abstract:

A system cleans a set of optical connectors. The system includes a fluid source, a vacuum source, a support member which defines a cleaning device edge, and a set of cleaning devices. Each cleaning device includes (i) a fluid intake member which connects to the fluid source, (ii) a fluid output member which connects to the vacuum source, and (iii) a cleaning head which connects to the fluid intake member and the fluid output member. Each cleaning device is disposed along the cleaning device edge of the support member. The set of cleaning devices is configured to (a) align over a set of optical interfaces of the set of optical connectors, (b) direct fluid (e. g. , gas, gaseous snow, etc. ) from the fluid source toward the set of optical interfaces, and (c) draw the directed fluid away from the set of optical interfaces and toward the vacuum source.

International Classification:

G02B 6/38
H01R 9/22

US Classification:

385 55, 385 73, 439717

Abstract:

An optical interconnection system, particularly useful in a backplane arrangement in an electronic assembly. The interconnection system includes “dual-use” protective covers for protection from damage and/or cleaning within backplane and daughter card style connectors. The protective covers are modular for easy use. Some versions contain adhesive members that can remove contaminates from various portions of the connector assembly. The protective covers can be inserted into a backplane connector of an electronic assembly using a tool or as part of a “dummy board. ”.

International Classification:

G02B 6/38

US Classification:

385 58, 385 55, 385 56, 385 60, 385 70, 385 72, 385 73, 385 75

Abstract:

An optical connector system joining waveguides in two printed circuit boards. A flexible optical conductor is connected at one end to one of the boards. The flexible conductor includes at its free end an alignment structure that provides a separable, low loss interface to an alignment structure coupled to the waveguide on the other board. The ends of the waveguides are enclosed in housings that protect the waveguides from abrasion and contaminates, but expose the waveguides when the connectors mate.

Amphenol Corporation - Wallingford CT

International Classification:

G02B 6/36

US Classification:

385 53

Abstract:

An optical connector system assembled from modular components. These components include connector modules that position ferrules for mating and providing fine alignment to fibers. The modules are assembled to support members to form connectors of various sizes. Mounting modules are attached to the support members. Various shaped mounting modules are provided, allowing connectors to be assembled for various configurations, such as a matrix configuration, a parallel board-to-board configuration or a panel mount configuration.
