Abstract: A steerable catheter sheath for use in directing a catheter into a desired position is provided. The sheath includes an elongated member configured to receive the catheter therein. The distal end of the elongated member is steerable in two directions, each direction having a different bent configuration, e.g., a sharp curve in one direction and an open arching curve in the other direction. A resilient structure having different bending properties in each of its lateral sides is carried in the distal portion of the elongated member and causes the asymmetric bending. In one embodiment, the resilient structure includes a hypotube with a plurality of notches and slits in the sides. In another embodiment, the resilient structure is covered in an outer coating having different durometer portions. The sheath is particularly useful for accessing left and right pulmonary veins when a transeptal entry approach is used into the left atrium.

Abstract: Systems, apparatus and methods for dispersing a coolant along different portions of a supply tube of a cryo-ablation device which may be in the form of a linear ablation device or catheter probe or a balloon catheter. A supply tube includes multiple tubes that are in fluid communication with an inner space of a transmissive region or an inner space of an inflatable balloon. The tubes are coaxially arranged and extend to different lengths or to different locations such that the coolant is dispersed from different tubes at different axial locations. Annular apertures are defined by pairs of tubes and have different sizes. The tubes and arrangement thereof are structured to provide uniform or substantially uniform coolant distribution to provide uniform or substantially uniform cryo-ablation of surrounding tissue.

Abstract: A method of performing a cryotherapy procedure can include introducing a cryotherapy balloon catheter at a treatment site inside a patient's body; regulating, during a first phase of a cryotherapy procedure, flow of cryogenic fluid to and exhaust from a distal balloon portion of the cryotherapy balloon catheter to cause an initial pressure to be maintained inside the distal balloon portion that is sufficiently high to cause an outer wall of the distal balloon portion to be pressed against body tissue at the treatment site; and regulating, during a second phase of the cryotherapy procedure, flow of cryogenic fluid to and exhaust from the distal balloon portion to cause a) a temperature inside the distal balloon portion to reach a value sufficient to deliver therapeutic levels of cryotherapy to the body tissue, and b) a second-phase pressure to be maintained that is within a threshold value of the initial pressure.

Abstract: A balloon elongation apparatus includes an elongated hypotube with a distal end having a reduced inner diameter portion that is configured to radially expand when a mandrel is advanced through a lumen of the hypotube towards the reduced inner diameter portion. A medical kit includes a catheter having a distally-located balloon and the elongation apparatus disposed within a guide wire tube of the catheter. In use, the balloon is elongated following a procedure in order to facilitate retracting the balloon into a sheath. The balloon is elongated by first advancing the mandrel relative to the hypotube so that the hypotube radially expands and firmly engages an inner surface of the guide wire tube and then advancing the mandrel, hypotube, and distal end of the guide wire tube relative to the catheter body.
