The present embodiments relate generally to systems and methods for measuring an analyte in a host. More particularly, the present embodiments provide sensor applicators and methods of use with activation that implant the sensor, withdraw the insertion needle, engage the transmitter with the housing, and disengage the applicator from the housing. Systems and methods according to present principles allow for such steps to occur without significant loss of spring force, and without deleterious effects such as seal slingshotting.

Transcutaneous analyte sensors, applicators therefor, and associated methods

A configuration for a cryo-catheter which optimizes both the catheter's outer diameter and the size of the catheter's internal refrigerant flow path is described. Specifically, the inner dimensions of the cryo-catheter are configured to accommodate a pre-selected flow of refrigerant into the catheter's distal tip, and a return flow of refrigerant from the distal tip. The return flow is established in the void spaces between a refrigerant supply line and the inner wall of the catheter body. The available void space varies along the catheter length and depends on the presence/absence of various catheter accessories (i.e. pull wires, pressure tubes, etc.) which typically only extend through a portion of the catheter length. The disclosed configuration ensures that the cryo-catheter does not operate in a refrigerant limited condition, maintains the refrigerant as a liquid in the supply tube, and maintains the return line pressure at about 1 atmosphere.

An applicator for cryoablating tissue to form linear (i.e. straight line and curvilinear) lesions in targeted tissue includes a fluid refrigerant delivery system having a source of a fluid refrigerant and a tubular cryoablation segment. Structurally, the segment has an open proximal end and a distal end, and is formed with a lumen. Also, the segment is formed with at least one distal port and at least one proximal port, with each port connected in fluid communication with the segment's lumen. The proximal end of the tubular segment is operably connected in fluid communication with the source of fluid refrigerant. For the system, the ports can be selectively sized to outflow liquid refrigerant through the distal and proximal ports at a substantially same mass flow rate.
