A cryosurgery system for application of medical-grade liquid nitrogen to a treatment area via a small, low pressure, open tipped catheter. The system includes a console, including a touch panel computer, a cryogen module, a suction module and an electronics module, and a disposable spray kit. Features include optional low cryogen flow setting to reduce the cryogen flow rate by 50%, improved cryogen flow consistency reducing pressure pulses and peaks, an integrated suction pump for improved consistency and self-checks, specified vent tube areas and corresponding maximum expected pressures during cryospray procedure; optional pressure sensing capability to monitor pressure during a treatment, and novel catheter designs of multilayer and flexible construction providing a variety of spray patterns.

Cryospray catheters

A method and system for automated and semi-automated predictable, consistent, safe, effective, and lumen-specific and patient-specific cryospray treatment of airway tissue in which treatment duration is automatically set by the system following entry of patient information and treatment location information into the system by the user, and treatment spray is automatically stopped by the system when the automatically selected treatment duration has been achieved as determined by the system.

Method and system for consistent, repeatable, and safe cryospray treatment of airway tissue

The present disclosure pertains to devices and methods for diagnosis and treatment of biological tissue in which the tissue is accessed by a catheter through a working channel of an endoscope and in which the degree of extension of a distal tip of the catheter beyond a distal tip of the endoscope is controlled.

Catheter extension control

The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to devices and methods to guide delivery devices and instruments. Exemplary instrument guides, including for endoscopes as delivery devices for cryogen delivery catheters and to guide cryogen decompression tubes as instruments, and methods for use of such instrument guides for use in body lumens at treatment sites, are disclosed.

Devices and methods for guiding instruments

The present disclosure relates generally to the field of cryotherapy. In particular, the present disclosure relates to cryotherapy systems that ensure egress of cryogen gas delivered within a patient's body during cryotherapy procedures and, more particularly, sensors for use with cryotherapy systems that include delivery catheters wherein the systems ensure that egress of cryogen gas from the patient's body is possible whenever the catheter is operating.

Systems and methods to ensure gas egress during cryotherapy

A bronchoscopic sheath adapted to be fit over the outside surface of the proximal portion of a bronchoscope to assist with measuring or spacing of treatment. The measurement or spacing sheath is preferably made of braided polymer filament and is configured to collapse under tension and open/expand when the ends of the sheath are pushed towards one-another. Markings are provided on the sheath at regular intervals to reflect distance. The markings may be woven into the braid, or printed on the exterior of the braid. The proximal end of the sheath may be flared and the distal end may be tapered. Each end may be provided with a cuff that may be part of the braid, or a separate elastomeric material, or a thermally sealed edge with atraumatic tip.
