Catheter shaft technology with HDPE liner introduced by Teleflex

A continuously wound, variable-pitch, coil-reinforced shaft technology with a high-density polyethylene (HDPE) liner has been introduced by Teleflex Medical OEM (Limerick, PA), a supplier of custom-engineered diagnostic and interventional catheters. The technology gives original equipment manufacturers new options for achieving precise performance characteristics along the catheter shaft while lowering assembly costs and improving kink resistance, says the company.

As endovascular devices become longer and thinner, there is a need for catheters with a rigid proximal end for pushability and torque without kinking or buckling, and a flexible distal end for successful navigation through tortuous pathways. Teleflex Medical OEM's variable-pitch, reinforcement technology allows customization of shaft performance without the assembly costs and weak bonded joints associated with traditional methods of catheter manufacturing.
