    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: 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 securement assembly for releasably securing an expandable stent or stent-graft relative to a delivery tube. The securement assembly comprises a belt base configured for securement relative to the delivery tube. The belt base defines a release member passage and a receiving portion. A first end of a belt is fixed relative to the belt base. The opposite end of the belt includes a retainment portion configured to releasably engage the receiving portion of the belt base. A release member is removably positioned through the release member passage and aligned with the belt retainment portion such that the retainment portion is maintained engaged with the receiving portion until the release member is moved to a non-aligned position. A method of releasably securing a portion of an expandable stent or stent-graft relative to a delivery tube is also provided.

    Abstract: A delivery system and method for delivering a bifurcated intracorporeal device. The delivery system comprises a shaft having a distal section supporting a primary support member positioned to be disposed within at least a primary portion of the bifurcated intracorporeal device and a secondary support member extending within a secondary portion of the bifurcated intracorporeal device. At least one belt is configured to be circumferentially disposed about a portion of the secondary support member so to at least partially constrain the secondary portion of the bifurcated intracorporeal device. A tube defining a lumen is secured relative to the secondary support member. A release member is configured to engage and releasably secure the belt in a constraining configuration. The release member extends through at least a portion of the tube lumen such that the release member is accessible adjacent a proximal end of the tube.

    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.
