Abstract

An improved peripherally inserted catheter with its soft ferule including a “ball-like” structure between the soft exterior tube and the soft ferule. A clamp is also provided which is characterized by a clamping force sufficient to clamp the exterior soft tube but insufficient to crimp the inner tube of the ferule for the situation where the clamp were to creep onto the ferule. A sterile screw assembly is coupled to the end of the ferule in another arrangement.

Claims

1. A peripherally inserted catheter assembly including an exterior tube and a soft ferule secured to an end thereof at an attachment point,

said soft ferule providing a flow path from an injection site to said exterior soft tube,

an enlarged radial section provided on said exterior soft tube adjacent said attachment point of said soft ferule with said exterior soft tube, whereby a clamp disposed about said exterior soft tube is prevented from creeping onto said soft ferule by said enlarged radial section on said exterior surface.
