Devices for transurethral thermal therapy
First Claim
1. An intraurethral catheter comprising:
- an elongate shaft having a first end, a second end, a first outer surface, and a second outer surface, the shaft further comprising;
a plurality of lumens which extend between the first end and the second end of the shaft including;
an antenna lumen having a generally circular transverse cross section and being positioned nearer the first outer surface than the second outer surface;
a first pair and a second pair of cooling lumens having a generally arc shaped transverse cross section and being configured and arranged to substantially surround the antenna lumen and to maximize exposure between the cooling lumens and the antenna lumen; and
an urine drainage lumen positioned between the second pair of cooling lumens adjacent the antenna lumen, the urine drainage lumen having a generally circular transverse cross-section and being arranged relative to the antenna lumen to minimize exposure between the urine drainage lumen and the antenna lumen.

Abstract
An intraurethral catheter shaft comprises a plurality of lumens extending between a first end and a second end of the shaft. An antenna lumen has a generally circular cross-sectional surface area and is positioned nearer a first outer surface than a second outer surface of the catheter shaft. A first and second pair of cooling lumens substantially surround the antenna lumen and have a generally arc shaped cross-sectional surface area. The cooling lumens are configured to be circumjacent to the antenna lumen about a substantial majority of the antenna lumen. A urinary drainage lumen is positioned between the second pair of cooling lumens adjacent the antenna lumen and has a generally circular cross-sectional surface area. The lumens of the catheter shaft are defined by a unitary wall having a substantially uniform thickness throughout the catheter.

16. An intraurethral catheter comprising:
an elongate shaft having a first end, a second end, a first outer surface, a second outer surface, and a plurality of lumens which extend between the first end and the second end of the shaft, the lumens being defined by an unitary wall having a substantially uniform wall thickness and including; an antenna lumen having a generally circular transverse cross section, wherein the antenna lumen is oriented nearer the first outer surface than the second outer surface; and a first and second pair of cooling lumens and an urine drainage lumen arranged to substantially surround the antenna lumen wherein an inner wall of the cooling lumens and the urine drainage lumen are common with a wall defining the antenna lumen so that each of the cooling lumens and the urine drainage lumen are spaced from the antenna lumen by no more than the substantially uniform wall thickness.
