Appl. No.:

09/261931

Inventors:

Dean M. Ponzi - Glendora CA
Craig S. Beshore - Glendora CA

Assignee:

Codris Webster, Inc. - Dismond Bar CA

International Classification:

B21B 146

US Classification:

295271, 295272, 29447, 604525, 604527

Abstract:

A deflectable catheter comprises a catheter body, a tip section, and a control handle for affecting deflection of the tip section. The tip section comprises a flexible tubing having proximal and distal ends and at least two lumens extending therethrough. The proximal end of the tip section is fixedly attached to the distal end of the catheter body. The flexible tubing comprises a plastic core, a metal braid over the core, a plastic skin over the braid, and at least two pieces of plastic tubing in longitudinal arrangement extruded over the plastic skin, wherein the at least two pieces of plastic tubing have different stiffnesses and are arranged with the stiffer plastic being proximal the less stiff plastic. The tip section is made by extruding a plastic core over at least one mandrel and braiding a metal over the plastic core. Thereafter, at least two pieces of plastic tubing having different degrees of stiffness are assembled along the length of the plastic core so that the piece of plastic tubing having the greatest stiffness is at the proximal end of the tip section and the piece of plastic having the lowest stiffness is near the distal end of the tip section.

Inventors:

Craig S. Beshore - Glendora CA, US

International Classification:

F02B075/02

US Classification:

123 65R, 123 66, 123 71 V, 417261, 417460

Abstract:

An apparatus useful in a two-stroke cycle engine or in a pump as a piston disposed within a piston cylinder. The piston cylinder has an intermediate piston cylinder head disposed transversely across the interior of the piston cylinder. The piston has a lower portion and at least one upright extension member extending upwardly from the lower portion. The upright extension member extends upwardly into the upper portion of the piston cylinder through a gap between the intermediate piston cylinder head and the piston cylinder wall. A piston top wall is disposed transversely to the piston cylinder side wall and is attached to the upper portion of the upright extension member of the piston. An upper piston cylinder chamber is defined above the piston top wall. An intermediate piston cylinder chamber is defined immediately below the piston top wall and a piston cylinder lower chamber is defined below the intermediate piston cylinder head.
