International Classification:

A61N 5/00

US Classification:

600 1

Abstract:

A handheld radiation delivery system is disclosed that includes a two-part delivery module comprising a reusable portion that contains a radioactive source wire and a disposable portion that includes a drive assembly for moving the radioactive source wire between storage and treatment positions. A disposable applicator tip is provided that includes a cannula for receiving the radioactive source wire when in the treatment position and a mechanism for limiting the number of uses of the device. A handheld cable actuator is operatively connected to the disposable portion of the handpiece to impart motion to the source wire.

A61B 18/02

US Classification:

606 21, 606 22, 606 27

Abstract:

Methods and apparatus for the treatment of a body cavity or lumen are described where a heated fluid and/or gas may be introduced through a catheter and into treatment area within the body contained between one or more inflatable/expandable members. The catheter may also have optional pressure and temperature sensing elements which may allow for control of the pressure and temperature within the treatment zone and also prevent the pressure from exceeding a pressure of the inflatable/expandable members to thereby contain the treatment area between these inflatable/expandable members. Optionally, a chilled, room temperature, or warmed fluid such as water may then be used to rapidly terminate the treatment session.
