Abstract

A multi-mode therapeutic balloon dilator capable of stent placement, argon plasma coagulation (APC) and monopolar electrosurgery. The device comprises a housing or base having a mechanism for moving a wire within an elongated flexible tube, a balloon port, an injection portion, a monopolar connector, and an argon gas connector.

Claims (27)

1 . A surgical device comprising:

an elongate catheter having a proximal end and a distal end and having a first and second channels therein, said first and second channels each having a proximal end and a distal end, and said first channel having a port in a distal end region of said elongate catheter, said elongate catheter having a diameter less than 3.8 mm;

a wire within said first channel, said wire having a proximal end and a distal end;

a housing connected near said proximal end of said tube, said housing comprising means for connecting said proximal end of said wire to a source of RF energy and means for connecting said proximal end of said first channel to a source of an inert ionizable gas; and

an inflatable member connected to said elongate catheter; said inflatable member being inflatable through said second channel in said elongate catheter.

2 . A surgical device according to claim 1 wherein said elongate catheter has a third channel therein.

3 . A surgical device according to claim 1 wherein said catheter is flexible.

4 . A surgical device according to claim 1 wherein said catheter is rigid.

5 . A surgical device according to claim 1 wherein said catheter is semi-rigid.

6 . A surgical device according to claim 1 wherein said inert ionizable gas comprises argon.

7 . A surgical device according to claim 1 wherein said wire is moveable within said first channel.

8 . A surgical device according to claim 1 further comprising:

means for moving said wire to a first position in which said distal end of said wire extends out of said port of said first channel and to a second position in which said distal end of said wire is within said first channel.

9 . A surgical device comprising:

a body member having a proximal end and a distal end and having first and second channels therein, said first and second channels each having a proximal end and a distal end, and said first channel having a port in a distal end region of said body member, said body member having a diameter less than 3.8 mm;

a flexible tube within said first channel and a wire within said flexible tube, said wire having a proximal end and a distal end;

a housing connected near said proximal end of said flexible tube, said housing comprising means for connecting said proximal end of said wire to a source of RF energy and means for connecting said proximal end of said flexible tube to a source of an inert ionizable gas; and

an inflatable member connected to said body member; said inflatable member being inflatable through said second channel in said body member.

10 . A surgical device according to claim 9 wherein said body member is flexible.

11 . A surgical device according to claim 9 wherein said body member is rigid.

12 . A surgical device according to claim 9 wherein said body member is semi-rigid.

13 . A surgical device comprising:

an elongate body member having a proximal end and a distal end and having a first and second channels therein, said first and second channels each having a proximal end and a distal end, and said first channel having a port in a distal end region of said body member, said body member having a diameter less than 3.8 mm;

a wire within said first channel, said wire having a proximal end and a distal end;

a housing connected near said proximal end of said body member, said housing comprising a first connector for connecting said proximal end of said wire to a source of RF energy and a second connector for connecting said proximal end of said first channel to a source of an inert ionizable gas; and

an inflatable member connected to said body member; said inflatable member being inflatable through said second channel in said body member.

14 . A surgical device according to claim 13 wherein said housing further comprises an adapter.
