Abstract
A cryogenic catheter includes an outer flexible member having a cryogenic fluid path defined by an injection tube disposed in the outer flexible member. The injection tube is slidably disposed within the outer flexible member. A guide member may be provided to support the injection tube within the outer flexible member. A wire is attached to the injection tube at one end and further attached to a spool to provide for take-up of the wire.
Claims8
A cryogenic catheter comprising:
- an elongate outer member, and
- an injection tube member having:
- a proximal end portion coupled to a supply of cryogenic fluid, and
- a distal end portion, the distal end portion further comprising at least one injection orifice formed thereon to selectively release cryogenic fluid,
- the injection tube member with the at least one injection orifice being movably coupled to the elongate outer member, the injection tube member and the at least one injection orifice being controllably and slidably disposed within the elongate outer member, the injection tube member defining a cryogenic fluid path through the elongate outer member.

A method of forming a moveable iceball comprising the steps of:
- providing a cryogenic catheter comprising a flexible member having an elongate injection tube disposed therein, the elongate injection tube having a distal end further comprising an injection orifice, and,
- providing a cryogenic fluid path through the injection tube, distal end, and injection orifice;
- introducing a cryogenic fluid into the injection tube wherein the injection tube and injection orifice are each respectively set at a first position within the flexible member;
- and
- repositioning the each of the injection tube and injection orifice to a second position within the flexible member.
