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.
Claims22
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 radio signal that powers the sensor, said sensor being configured for wirelessly sending a data-containing radio signal to the local power-delivery/data-reception unit.
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 an electromagnetic signal that powers the sensor, said sensor being configured for wirelessly sending an electromagnetic data signal to the local power-delivery/data-reception unit,
- further comprising, for said returning by the sensor, a magnetic loop antenna having an inner coil and an outer coil, each coil having two loops in respective parallel planes, the inner loop being nested within the outer loop.
A method for assembling a catheter, comprising:
- providing a catheter body with a handle, and an insertion end for inserting into a patient;
- configuring a local power-delivery/data-reception unit to be incorporated within said end for wirelessly emitting a radio signal that powers a sensor to be adjoined to said end;
- configuring the sensor for wirelessly sending, to the local power-delivery/data reception unit, a data-containing radio signal;
- disposing the local power-delivery/data reception unit within said end;
- sealing the sensor and the catheter body so that they are sealed from each other;
- and
- adjoining the sealed sensor to said end.
A method for assembling a catheter, comprising:
- providing a catheter body with a handle, and an insertion end for inserting into a patient;
- configuring a local power-delivery/data-reception unit to be incorporated within said end for wirelessly emitting an electromagnetic signal that powers a sensor to be adjoined to said end;
- configuring the sensor for wirelessly sending, to the local power-delivery/data reception unit, an electromagnetic data signal;
- disposing the local power-delivery/data reception unit within said end;
- sealing the sensor and the catheter body so that they are sealed from each other;
- and
- adjoining the sealed sensor to said end,
- wherein said configuring of the sensor comprises providing a magnetic loop antenna having an inner coil and an outer coil, each coil having two loops in respective parallel planes, the inner loop being nested within the outer loop, wherein said providing of the magnetic loop antenna comprises configuring the inner and outer coils to be electrically isolated from each other and disposed to communicate energy with one another by mutual inductance.
