SYSTEMS AND METHODS OF POSITION AND MOVEMENT DETECTION FOR UROLOGICAL DIAGNOSIS AND TREATMENT
First Claim
1. A system for urological diagnostics and treatment, the system comprising:
- a flexible tube or catheter;
a plurality of MEMS sensors in the flexible tube or catheter to provide tracking of the flexible tube or catheter, wherein the MEMS sensors of the plurality of MEMS sensors are spaced apart from each other along the length of the flexible tube or catheter by a pitch providing sufficient data points while maintaining flexibility of the flexible tube or catheter; and
a wiring connected to the plurality of MEMS sensors for providing power to and signals from the plurality of MEMS sensors.

Abstract
Systems and methods of detecting position and movement of the bladder and urethra are provided. In one embodiment, a system is provided including a flexible tube, or catheter, with one or more MEMS sensors and an RF antenna embedded thereon; and an RF receiver located external to the flexible tube. The sensors in the flexible tube can be connected to external electronics, which are in turn connected to a computing device. The MEMS sensors provide motion detection and the RF sensors provide position/distance detection. The MEMS sensors can include, but are not limited to, one or more accelerometers, gyroscopes, stress sensors, tilt sensors, and/or pressure sensors. In operation, the flexible tube is inserted into the bladder through the urethra to detect the location of the bladder neck and track the motion and/or shape of the urethra. The results of the tracking can be provided on a display.

15. A system for urological diagnostics and treatment, the system comprising:
-
a flexible tube or catheter; a transmitting (TX) antenna in the flexible tube or catheter, wherein the TX antenna transmits a TX signal; a receiving (RX) antenna external to the flexible tube or catheter for being positioned at a location on a patient, wherein the RX antenna receives the TX signal and outputs an RX signal; a phase shifter and amplifier providing a quadrature shifted reference local oscillator (LO) signal by phase shifting and amplifying the TX signal; and a mixer mixing the RX signal and the LO signal to output an output signal including a DC voltage proportional to a phase shift between the LO signal and the RX signal, the output signal providing positioning information of the flexible tube or catheter. - View Dependent Claims (16, 17, 18, 19, 20)
