Abstract
A needle assembly for use with an ultrasound imaging system includes a needle having a proximal end and a distal end. The distal end is adapted to be inserted into a patient. The needle assembly also includes a transducer mounted to an exterior surface of the needle at the distal end. Further, the needle assembly includes a flexible printed circuit board mounted on the exterior surface of the needle from the proximal end to the distal end. As such, the flexible printed circuit board electrically connects the transducer to a power source.
Claims21
An active needle assembly for use with an ultrasound imaging system, the needle assembly comprising:
- a needle comprising a proximal end and a distal end, the distal end adapted to be inserted into a patient;
- a needle transducer mounted to an exterior surface of the needle;
- and
- a flexible printed circuit board mounted on the exterior surface of the needle, the flexible printed circuit board electrically connecting the needle transducer to a power source.
A needle assembly for use with an ultrasound imaging system, the needle assembly comprising:
- a needle comprising a proximal end and a distal end, the distal end adapted to be inserted into a patient;
- a needle transducer mounted to an exterior surface of the needle at the distal end;
- a conduit assembly secured to an exterior surface of the needle from the proximal end to the distal end, the conduit assembly defining at least one lumen therethrough;
- and
- at least one electrically-conductive cable extending through the conduit assembly and electrically connecting the transducer to a power source
The needle assembly of claim 14, wherein the conduit assembly is arranged linearly from the proximal end to the distal end of the needle.
The needle assembly of claim 14, wherein the conduit assembly is arranged in a helical pattern from the proximal end to the distal end of the needle.
A needle assembly for use with an ultrasound imaging system, the needle assembly comprising:
- a needle comprising a proximal end and a distal end, the distal end adapted to be inserted into a patient;
- a transducer mounted to an exterior surface of the needle at the distal end;
- and
- at least one electrical trace printed on the exterior surface of the needle from the proximal end to the distal end via an additive manufacturing process, the at least one electrical trace electrically connecting the transducer to a power source.
