US Patent:

20110005661, Jan 13, 2011

Filed:

Sep 8, 2010

Appl. No.:

12/877245

Inventors:

JOHN R. BRUSTAD - Dana Point CA, US
SAID S. HILAL - Coto De Caza CA, US
NABIL HILAL - Laguna Niguel CA, US
CHARLES C. HART - Summerville SC, US
GARY M. JOHNSON - Mission Viejo CA, US
SERENA HILAL - Rancho Santa Margarita CA, US

EDWARD D. PINGLETON - San Juan Capistrano CA, US
MATTHEW N. PETRIME - Los Angeles CA, US
PAYAM ADLPARVAR - Lake Forest CA, US
CARL B. HADLEY - Foothill Ranch CA, US
KENNETH K. VU - San Diego CA, US

Assignee:

Applied Medical Resources Corporation - Rancho Santa Margarita CA

International Classification:

B29D 23/20

US Classification:

156143

Abstract:

The invention primarily is directed to a medical tubing adapted for insertion into a body tissue or cavity and method of manufacturing different variations of the tubing along a length of the tubing. The tubing comprises a plurality of individual, discrete, generally ring-shaped elements arranged in series and fused or bonded together forming a continuous tubular structure. The ring-shaped elements may be formed of a thermoplastic or a thermoset material. The ring-shaped elements may include plastic rings, metallic rings, un-reinforced plastic rings and/or metal reinforced plastic rings assembled along the length of the tubular structure to provide variable flexibility and kink-resistance. The tubular structure may have a cross-section of any geometric shape and it may be bent, twisted or curved without kinking. The ring-shaped elements may have different flexural modulus. The ring-shaped elements may include a combination of flexible and rigid ring-shaped elements assembled along different portions or sections of the tubular structure. The ring-shaped elements may be metallic and may be bonded with a resilient, flexible elastomeric adhesive, wherein the ring-shaped elements may have different lengths and may be fused closer or further apart to one another depending on the characteristics of a portion or section of the tubing. In another aspect of the invention, the medical tubing may further comprise a secondary lumen and a pull wire to control the tubular structure. The ring-shaped elements may be truncated to provide a bending bias. In another aspect of the invention, the ring-shaped elements may vary in diameter and/or composition in different portions or sections of the tubular structure. In yet another aspect of the invention, some of the ring-shaped elements may be radiopaque, or the ring-shaped elements may comprise of different colors to operate as indicators along the tubular structure.
