Introduction

Lex P Jansen is a notable inventor based in Londonberry, NH, who has made significant contributions to the field of medical devices. With a total of three patents to his name, Jansen's work focuses on enhancing the performance and functionality of medical guidewires.

Latest Patents

One of Jansen's latest patents is for high-performance wires designed for use in medical devices. This invention features an elongate flexible wire-like medical device, such as a guidewire for use with a catheter. The design reduces the difference between the tensile yield stress and compressive yield stress of the shaft, resulting in superior kink resistance without compromising other desirable characteristics. This innovation allows for the creation of guidewires in smaller diameters without loss of performance. The guidewire shaft can be made from various alloys, including nickel, cobalt, molybdenum, and chromium, as well as stainless steel.

Another significant patent by Jansen involves a catheter guidewire equipped with radiopaque markers. This guidewire features varying radiopacity and includes at least one radiopaque marker at its distal end. The design incorporates a shaft that supports both distal and proximal radiopaque coils, providing several radiographically visible reference lengths. The use of a polymer sleeve encasing the marker bands ensures a uniform outer diameter in the distal region of the guidewire.
