Filed:

Oct 14, 2011

Appl. No.:

13/273918

Inventors:

Rafi Avitsian - Solon OH, US
Andrew M. Zura - Broadview Heights OH, US
Robert B. Guthrie - Ventura CA, US

International Classification:

A61B 1/00

US Classification:

600121

Abstract:

A sheath assembly for an endoscope includes an elongate tubular body and a plug. The endoscope has a handle portion and a scope portion extending therefrom to a tip. The body includes first and second wall sections and extends along a longitudinal axis between first and second distal openings located at distal and proximal ends thereof, respectively. The first wall section extends radially about the longitudinal axis to define a scope lumen. The scope portion is receivable in the scope lumen with the distal and proximal ends. The second wall section extends radially about a portion of the first wall section and longitudinally between second distal and proximal end openings. The first and second wall sections define an integral suction lumen in fluid communication with a first source of negative pressure. The plug is mated with the distal end opening and includes a lens surface through which energy is transmissible.

A61M 25/092

US Classification:

604 9504, 604525

Abstract:

A catheter assembly comprises a first catheter including a wall with an inner surface at least partially defining a lumen. A second catheter is connected to the wall of the first catheter and is disposed outward of the inner surface of the wall. The second catheter is at least partially covered by a sheath portion of the first catheter. A first portion of the wall of the first catheter is made of a relatively low durometer elastomeric material and is relatively extensible. A second portion of the wall is formed of a relatively high durometer elastomeric material and is relatively inextensible.

Abstract:

A sheath assembly for an endoscope includes an elongate tubular body and a plug. The endoscope has a handle portion and a scope portion extending therefrom to a tip. The body includes first () and second () wall sections and extends along a longitudinal axis between first and second distal openings located at distal and proximal ends thereof, respectively. The first wall section () extends radially about the longitudinal axis to define a scope lumen (). The scope portion is receivable in the scope lumen with the distal and proximal ends. The second wall section () extends radially about a portion of the first wall section () and longitudinally between second distal and proximal end openings. The first and second wall sections define an integral suction lumen () in fluid communication with a first source of negative pressure. The plug is mated with the distal end opening and includes a lens surface through which energy is transmissible.
