Abstract
Official abstract text for this publication.
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.
