Abstract: An adapter for putting two incompatible medical systems in fluid communication with each other. The adapter may have a continuous outer diameter and may include two segments: a first segment composed of a rigid material and including a first portion and a second portion, the first portion having a continuous outer diameter and the second portion defining one or more flanges, the first segment defining a first passage therethrough; and a second segment composed of a flexible material and coupled to the first segment, including a first portion and a second portion. The first portion of the second segment may have an inner surface configured to surround the flanges of the second portion of the first segment, and the second portion of the second segment having a tapered inner surface, the second segment defining a second passage therethrough that is continuous with the first passage.

Abstract: The present invention may include a medical device having a handle, a catheter coupled to the handle, and an expandable element coupled to the catheter. The medical device may also include first and second elongate bodies that traverse a length of the handle and the catheter. A housing may be disposed within the handle, with the housing defining a first opening able to receive a portion of the first elongate body, a second opening able to receive a portion of the second elongate body, and a third opening opposite the first and second openings able to receive a portion of both the first and second elongate bodies. A separation element may be disposed within the housing, with the separation element defining a path able to receive a portion of the second elongate body, and whereby a portion of the first elongate body forms a loop around the separation element.

Abstract: A method for purging a cryotreatment system, in particular, for clearing moisture and thus preventing ice blockages within a fluid flow path that may be formed when moisture pockets within the fluid flow path of the system are encountered by a first injection of refrigerant at the beginning of a cryotreatment procedure. The method may include injecting refrigerant from a refrigerant source into a fluid delivery conduit at a preselected pressure for a first period of time, the refrigerant flowing from the fluid delivery conduit through a fluid injection element and into a fluid recovery conduit, and evacuating refrigerant from the fluid recovery conduit by vacuum pressure generated by the vacuum pump for a second period of time. This method may be repeated for a plurality of cycles.
