ABSTRACT:
A catheter apparatus for use in determining the location of a tip of a catheter inside biological tissue is disclosed. The apparatus includes a catheter, a detector positioned within the catheter, and a polyimide sheath containing the detector and forming a detector assembly. The sheath is comprised of a first member, a polyimide layer, and a second member having an undulating outer surface sandwiched therebetween. The detector assembly may be removed from the catheter without damage thereto once the tip of the catheter is in its desired location inside biological tissue.
