Assignee:

Tyco Healthcare Group LP - Mansfield MA

International Classification:

B29C 47/00
A61M 31/00
A61M 37/00

US Classification:

156245, 604 9301, 604540

Abstract:

A urology catheter is provided that includes an elongated body extending from a proximal end to a distal end. The body defines at least one lumen. A tip has a proximal end that is disposed in abutting relation with the distal end of the body such that the body is fixed with the tip. The tip defines a lateral opening that is defined by a wall including an external radius disposed in transition with an outer surface of the tip and an internal radius disposed in transition with an inner surface of the tip. The external radius has a non-perpendicular profile with the outer surface of the tip. An expandable member has a proximal portion disposed about the body and a distal portion disposed about the tip. A method of manufacturing the urology catheter is provided.

US Classification:

Abstract:

A chassis and circuit modules for controlling electromagnetic interference in high-speed digital transceiver circuits. The impedance between a reference ground point and the transceiver circuits and a chassis wall through which the transceiver circuit signals pass is kept very low by intimate physical contact between a conductive bulkhead section of the module and the ground plane used by the transceiver. In particular, there is disclosed an arrangement whereby a plurality of modules are placed adjacent one another in a cabinet. Each of the modules contains a conductive bulkhead section or handle, which engages other adjacent bulkhead sections, and which may have an input/output connector mounted thereon. Each module also has a printed circuit board mounted to the bulkhead section so that a forward-circuit reference path reserved for use by transceiver circuits is positioned adjacent the connector and electrically connected to both the connector and the front section via a low impedance path. No partitions between the bulkhead sections are necessary since conductive springs formed on the lateral edges of the bulkheads provide electrical continuity between them.
