A method, system and device for securing conductive material on catheter elements for tissue sensing and cryogenic ablation. This may be used to deposit or embed conductive material onto or within polymeric materials. The method of manufacturing a balloon with conductive material may include extruding a polymeric material where the polymeric material includes embedded electrically conductive material. At least a portion of the polymeric material may be removed to expose at least a portion of the embedded electrically conductive material. The benefits may include allowing local bipolar recordings, contact assessment and ice thickness, and compatibility with 3-dimensional electroanatomical mapping systems.

In various embodiments, a device is provided comprising a balloon configured to expand to an expanded state in response to introduction of a fluid at a first pressure, wherein the fluid perfuses through the balloon above a second pressure, the second pressure being the same or greater than the first pressure. In various embodiments, a method comprising fabricating a balloon configured to expand to an expanded state in response to introduction of a fluid at a first pressure, wherein the fluid perfuses through the balloon above a second pressure, the second pressure being at or greater than the first pressure, disposing the balloon on an elongate member having a lumen, placing the lumen in fluid communication with an interior volume of the balloon.

A medical device may include a catheter, an expandable member, a cover, and an actuator. The catheter may include a longitudinal axis, proximal and distal ends, and a cover lumen extending from the proximal to the distal end. The expandable member may include proximal and distal ends and may be disposed on a distal section of the catheter. The cover may include a first region that may be disposed along the expandable member, and a second region that may extend along a length of the catheter beyond the proximal end of the expandable member towards the proximal end of the catheter. A first end of the cover may invert into the cover lumen. The actuator may be coupled to the first end of the cover and configured to move the first end of the cover towards the proximal end of the catheter along the longitudinal axis of the catheter.
