## Abstract

A local power-delivery/data-reception unit is installed within an insertion end of a sealed catheter. The local power-delivery/data-reception unit wirelessly powers a separately sealed sensor that is attached to the insertion end and configured for wirelessly sending a data signal to the local power-delivery/data-reception unit. The catheter may further feature a remote power-delivery/data-reception unit disposed within the handle and configured for wirelessly communicating with the local power-delivery/data-reception unit and a controller for controlling the sensor.

## Claims

### Claim 1

A catheter, comprising:
a sealed catheter body including a handle and an insertion end for inserting into a patient, and
a sealed sensor adjoined to said insertion end, the sensor and catheter body being sealed from each other, and
a local power-delivery/data-reception unit incorporated at the insertion end and configured for wirelessly emitting a signal that powers the sensor, said sensor being configured for wirelessly sending a data signal to the local power-delivery/data-reception unit.

### Claim 2 (depends on 1)

The catheter of claim 1, further comprising a remote power-delivery/data-reception unit disposed within the handle and configured for wirelessly communicating with the local power-delivery/data-reception unit and a controller for controlling the sensor.

### Claim 3 (depends on 1)

The catheter of claim 1, further comprising an integrated circuit incorporating the sensor and incorporating an electro-static antenna, said unit also incorporating an electro-static antenna, for communicating wirelessly with the electro-static antenna in the integrated circuit.

### Claim 4 (depends on 1)

The method of claim 1, further comprising disposing a remote power-delivery/data-reception unit within the handle for wirelessly communicating with the local power-delivery/data-reception unit.

### Claim 5 (depends on 1)

The unit of claim 1, wherein said catheter comprises a handle, said unit being further configured for wirelessly relaying the data signal to a remote power-delivery/data-reception unit within the handle and for receiving, from the remote power-delivery/data-reception unit, a power signal serving as a power source for said powering.
