Abstract
Apparatuses, methods, systems, and program products are disclosed for an ultrasound-equipped catheter stylet system. An apparatus includes a catheter and a stylet configured for insertion into the catheter. The stylet includes a shaft having a first end and a second end and an ultrasound transceiver coupled to the first end of the shaft, the ultrasound transceiver configured to transmit and receive an ultrasound signal.
Claims20
An apparatus, comprising:
- a catheter;
- and
- a stylet configured for insertion into the catheter, the stylet comprising:
- a shaft having a first end and a second end, wherein the shaft comprises at least one channel along a length of the shaft that creates at least one space between the catheter and the shaft when the stylet is inserted into the catheter;
- and
- an ultrasound transceiver coupled to the first end of the shaft, the ultrasound transceiver configured to transmit and receive an ultrasound signal.

A system, comprising:
- a catheter;
- a stylet configured for insertion into the catheter, the stylet comprising:
- a shaft having a first end and a second end, wherein the shaft comprises at least one channel along a length of the shaft that creates at least one space between the catheter and the shaft when the stylet is inserted into the catheter;
- an ultrasound transceiver coupled to the first end of the shaft, the ultrasound transceiver configured to transmit and receive an ultrasound signal;
- and
- a position sensor that detects a position of the stylet relative to a fixed point;
- a memory;
- and
- a processor coupled with the memory and the stylet, the processor configured to:
- receive a signal from the ultrasound transceiver;
- generate a multi-dimensional graphic based on the signal;
- and
- present the multi-dimensional graphic on a display device.

A method, comprising:
- inserting a stylet into a catheter, the stylet comprising:
- a shaft having a first end and a second end, wherein the shaft comprises at least one channel along a length of the shaft that creates at least one space between the catheter and the shaft when the stylet is inserted into the catheter;
- an ultrasound transceiver coupled to the first end of the shaft, the ultrasound transceiver configured to transmit and receive an ultrasound signal;
- and
- a position sensor that detects a position of the stylet relative to a fixed point;
- inserting the catheter into a body;
- causing the ultrasound transceiver to generate the ultrasound signal;
- moving the stylet in a conical manner as the catheter is inserted into the body;
- receiving position data from the position sensor and signal data from the ultrasound transceiver as the stylet is moved;
- and
- generating a multi-dimensional graphic of a portion of the body where the catheter is inserted based on the position data and the signal data.
