1. A cryo therapy device, comprising:
- an elongate shaft having a proximal end and a distal end;
a cooling member disposed at the distal end, wherein the cooling member includes an outer member and an inner member;
an inflation tube disposed within the elongate shaft;
a drain tube disposed within the elongate shaft;
a pressure sensor that is disposed near the distal end of the elongate shaft to provide an indication of the pressure within the inner member; and
a manifold disposed at the proximal end of the elongate shaft, wherein the pressure sensor is coupled to the manifold by a connector.

30. A method of performing cryoplasty, comprising the steps of:
-
providing a cryo therapy device including an elongate shaft having a proximal end and a distal end, a manifold disposed at the proximal end, a cooling member disposed at the distal end, wherein the cooling member includes an outer member and an inner member, and a pressure gauge coupled to the inner member and coupled to the manifold by a connector such that pressure within the inner member may be quantified by the manifold;
advancing the cryo therapy device to an area of interest;
inflating the inner member of the cooling member with a coolant to a pressure;
quantifying the pressure with the pressure gauge; and
cooling the area of interest with the cooling member. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37)
