摘要:
A multilumen catheter shaft body includes a proximal end segment with a first durometer and a first longitudinal length dimension. A proximal intermediate segment is fixedly joined to a distal end of the proximal end segment and includes a second durometer and a second longitudinal length dimension. A distal intermediate segment is fixedly joined to a distal end of the proximal intermediate segment and includes a third durometer and a third longitudinal length dimension. A distal terminal end segment is fixedly joined to a distal end of the distal intermediate segment and includes a fourth durometer and a fourth longitudinal length dimension. The first durometer is greater than at least the second and third durometers. The fourth durometer is greater than at least the second and third durometers. A plurality of parallel longitudinal lumens extends through the body, providing a structure useful in a cholangioscope or other endoscopic applications.
