Abstract
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.
