Abstract
A tubing assembly includes a signal generating apparatus for a catheter placement system. The tubing assembly includes a catheter and a signal generating apparatus. The catheter includes an elongate shaft having a wall surrounding a lumen. The signal generating apparatus includes at least one electromagnetic coil and at least one electrically conductive polymer that is configured to electrically connect the at least one electromagnetic coil to a monitor unit.
Claims20
A tubing assembly comprising:
- an enteral catheter having an elongate shaft having an outer wall surrounding a lumen, the elongate shaft having a length extending from a proximal end to a distal end and extending in a longitudinal direction, wherein the lumen extends from the proximal end to the distal end, the enteral catheter further comprising a tip at the distal end having a body comprising a collar, an end member, and an opening positioned between the collar and the end member, further wherein the enteral catheter has a size in a range from 5 gauge to 20 gauge;
- and
- a signal generating apparatus including a signal generator at or near the distal end of the elongated shaft and at least one electrically conductive polymer extending along the entire length of the elongate shaft from the proximal end to the distal end, further comprising a connector comprising at least one electrical contact configured to connect to a wire assembly, wherein the at least one electrically conductive polymer is configured to electrically connect the at least one signal generator to a monitor unit via the wire assembly;
- wherein the outer wall comprises the at least one electrically conductive polymer;
- and
- wherein the electrically conductive polymer surrounds the at least one signal generator.

A signal generating apparatus comprising:
- a signal generator;
- at least one electrically conductive polymer;
- and
- a connector comprising at least one electrical contact configured to connect to a wire assembly, wherein the at least one electrically conductive polymer is configured to electrically connect the at least one signal generator to a monitor unit via the wire assembly;
- wherein the signal generator and the at least one electrically conductive polymer are configured to be integrated within a catheter comprising a lumen, wherein the at least one electrically conductive polymer is spaced further from the lumen of the catheter in a radial direction than the signal generator, further wherein the at least one electrically conductive polymer is configured to extend continuously from a proximal end of the catheter to a distal end of the catheter and the signal generator is configured to be disposed at or near the distal end of the catheter.
