Abstract

A urethral profile apparatus, assembly and appurtenant methodology is provided. The apparatus includes an elongate member having proximal and distal ends, the proximal end including a probe. The probe is selectively positionable within a urethral passageway by axial translation of the elongate member via the distal end, with the probe dimensioned so as to indicate constrictures of the urethral passageway.

Claims

1. An endourethral assembly comprising a urethral profiling apparatus adapted so as to be supported by a catheter, and a probe wire having a proximal end and a distal end having a grip, said urethral profiling apparatus comprising a probe dimensioned so as to tactilely indicate constrictures of a urethral passageway, said probe supported at said proximal end of said probe wire for axial translation with respect thereto, at least a portion of said probe wire including spaced apart markings.

2. The assembly of claim 1 wherein at least a portion of said catheter includes at least a single marking.

3. The assembly of claim 2 wherein axial travel of said probe relative to said catheter is proximally limited by a portion of a proximal end of said catheter.

4. The assembly of claim 3 wherein said portion of said proximal end of said catheter comprises an anchor element.

5. The assembly of claim 4 wherein said anchor element comprises a reversibly expandable balloon.

6. The assembly of claim 3 wherein axial travel of said probe relative to said catheter is proximally limited by abutting engagement of a distal segment of said probe wire with a distal extremity of a distal portion of said catheter.

7. The assembly of claim 6 wherein said distal segment of said probe wire comprises said grip.

8. The assembly of claim 6 wherein said axial travel of said probe relative to said catheter is distally limited by abutting engagement of said probe with a stop of said catheter.

9. The assembly of claim 8 wherein said apparatus further includes a supplemental probe wire support, said supplemental probe wire support adapted to maintain said probe wire not greater than a preselected distance from said catheter.

10. The assembly of claim 9 wherein said supplemental probe wire support reversibly circumscribes said probe wire and said catheter.

11. The assembly of claim 9 wherein said supplemental probe wire support slidingly receives said probe wire for axial translation therethrough.

12. The assembly of claim 11 wherein said probe circumscribes an outer surface of said catheter.

13. The assembly of claim 12 wherein said stop defines a maximum cross section for a body of said catheter.

14. The assembly of claim 13 wherein said stop is positioned distally relative to said probe.

15. The assembly of claim 14 wherein said stop circumscribes said outer surface of said catheter.

16. The assembly of claim 15 wherein said stop is adapted to slidingly receive said probe wire.

17. The assembly of claim 13 wherein a radial projection from said body of said catheter defines said stop.

18. A urethral profile apparatus comprising an elongate member having proximal and distal ends, said proximal end comprising a tubular element and a probe integral thereto, said tubular element including a line of weakness in a wall thereof, said probe being adapted to be received upon a catheter for select positioning within a urethral passageway by axial translation of said elongate member via said distal end along a segment of the catheter, said probe being resiliently responsive and dimensioned so as to indicate constrictures of the urethral passageway.

19. A urethral profile apparatus comprising an elongate member having proximal and distal ends, said proximal end comprising a tubular element and a probe integral thereto, said tubular element including a slot in a wall thereof, said probe comprising a free end of said tubular element and adapted to be received upon a catheter for select positioning within a urethral passageway by axial translation of said elongate member via said distal end along a segment of the catheter, said probe being resiliently responsive and dimensioned so as to indicate constrictures of the urethral passageway.
