Catheter type sensor
First Claim
1. A catheter comprising:
- a detecting portion including a base, at least one sensor element supported on said base for detecting biological data, and a biocompatible resin material in which said base and said sensor element are embedded; and
an elongated body portion supporting said detecting portion and including means for transmitting data between said sensor element and an external measuring device, and a biocompatible resin material in which said data transmitting means are embedded;
said detecting portion being defined at one of a distal end and an intermediate portion of said elongated body portion, said resin materials of said detecting portion and of said elongated body portion being integral so as to define the exterior surface of a catheter.

Abstract
A catheter type sensor, which is inserted into a living body in order to directly measure within the living body biological data such as blood pressure, has at least one base in its distal end or intermediate portion, at least one sensor element supported on the base to detect biological data, and lead wires for electrically connecting together the sensor element and an external measuring device. The base, the sensor element and the lead wires are buried in a resin material which has excellent compatibility with living bodies and which is shaped in the form of a catheter. Accordingly, the whole of the cross-sectional area of the sensor can be utilized as a space for mounting the assembly constituted by the base, the sensor element and the lead wires.
