The C2 CryoBalloon™ Ablation System is intended for use as a cryosurgical tool in the field of general surgery, specifically for endoscopic applications, to include ablation of Barrett's Esophagus with dysplasia.

The C2 CryoBalloon Ablation System is a cryosurgical device, which consists of four (4) components: (i) a single-use, sterile balloon Catheter that is inserted through the working channel of an endoscope with a minimum inner diameter (ID) of 3.7 mm and a maximum working length of 100 cm; (ii) a hand-held reusable Controller with a liquid crystal display (LCD) touch screen interface; (iii) a reusable Foot Pedal that is plugged into mains, provides power for the Controller, and allows the user to operate system functions such as ablation targeting, nitrous oxide flow control, and balloon deflation; and (iv) single-use Nitrous Oxide Cartridge that provides users with cryogen for each treatment. The C2 CryoBalloon Ablation System uses nitrous oxide as a cryogen to cause necrosis of targeted tissue in a controlled manner. The low operating pressure inflates the compliant balloon against the lumen ID. Nitrous oxide is directed at the targeted tissue and it evaporates on the inner surface of the balloon and freezes the tissue. The nitrous oxide is fully contained within the balloon and the resultant gas exhausts through the Catheter shaft and vents through the Controller. There are four (4) Catheter configurations that distribute nitrous oxide focally (focal diffuser), over a quarter of the lumen circumference (90° diffuser), over half of the lumen circumference (180° diffuser), or over the full circumference of the lumen (360° diffuser). The user selects the Catheter with the desired diffuser type, removes it from the sterile packaging and inserts it through the working channel of an endoscope until the balloon portion exits the distal end of the endoscope. The connector portion of the Catheter is inserted into the Controller and the radiofrequency identification (RFID) communication system in the Catheter connector and the Controller allows the Controller to perform functions specific to the Catheter. The LCD touch screen allows the user to set desired dosimetry, and communicates system status to the user. The user tightens the Controller Cap against the Controller, which pierces the nitrous oxide Cartridge. Nitrous oxide is contained in the Controller until the user steps on the Foot Pedal to allow the Controller to release it into the Catheter. The user visualizes the targeting and ablation via the inflated balloon and the images provided by the endoscope. The balloon is held in contact with the treatment area during the ablation. Upon conclusion of the procedure the balloon is deflated and withdrawn into the endoscope.

The subject device is a cryosurgical system with a nitrous oxide cooled balloon that is compatible with a commercially available endoscope with a minimum working channel inner diameter (ID) of 3.7 mm and length of 100 cm. The subject device is a system comprised of a Catheter (sterile), Controller (non-sterile), and Cartridge (nonsterile). The subject device is used to ablate unwanted tissue by application of extreme cold to a 360° circumference. 90° circumference. or 45° circumference and is identical to the respective predicates. The balloon at the distal end of the Catheter comes in contact with tissue and is inflated with nitrous oxide. Tissue is visualized through the preinflated balloon, and the treatment site is selected by adjusting the endoscope and Controller position. The nitrous oxide spray cools the balloon to ablate the unwanted tissue, and the nitrous oxide exhausts through the Controller.

The C2 CryoBalloon™ Focal Ablation System is intended to be used as a cryosurgical tool for the destruction of unwanted tissue in the field of general surgery, specifically for endoscopic applications.

The subject device is the Catheter used as part of a cryosurgical unit with a nitrous oxide cooled balloon that is compatible with commercially available endoscopes with a minimum working channel inner diameter (ID) of 3.7 mm and maximum length of 100 cm. The subject Catheter is part of a cryosurgical system comprised of three components including a Catheter (sterile, single use), Controller (non-sterile, reusable), and Cartridge (non-sterile, single use). The subject device is used to ablate unwanted tissue by application of extreme cold. The balloon at the distal end of the Catheter is comes in contact with tissue and is inflated with nitrous oxide. Tissue is visualized through the pre-inflated balloon, and the treatment site is selected is by adjusting the endoscope and Controller. The nitrous oxide spray cools the balloon to ablate the unwanted tissue, and the nitrous oxide exhausts through the Controller.

The Coldplay CryoBalloon™ Focal Ablation System, Coldplay CryoBalloon™ Full Ablation System, and Coldplay CryoBalloon™ Swipe Ablation System are intended for use as a cryosurgical tool in the field of general surgery, specifically for endoscopic applications, to include ablation of Barrett's Esophagus with high grade dysplasia.

The subject device is a cryosurgical system with a nitrous oxide cooled balloon that is compatible with commercially available endoscopes with a minimum working channel inner diameter (ID) of 3.7 mm and length of 100 cm. The subject device is a system comprised of three components including a Catheter (sterile), Handle (nonsterile), and Cartridge (non-sterile). The subject device is used to ablate unwanted tissue by application of extreme cold to a 360° circumference, 90° circumference, or 45° circumference and is identical to the respective Coldplay CryoBalloon™ Ablation System predicates. The balloon at the distal end of the Catheter comes in contact with tissue and is inflated with nitrous oxide. Tissue is visualized through the pre-inflated balloon, and the treatment site is selected by adjusting the endoscope and Handle. The nitrous oxide spray cools the balloon to ablate the unwanted tissue, and the nitrous oxide exhausts through the Handle.

The Coldplay CryoBalloon® Ablation System is intended for use as a cryosurgical tool for the destruction of unwanted tissue in the field of general surgery, specifically for endoscopic applications.

The modified device is the Catheter used as part of a cryosurgical unit with a nitrous oxide cooled balloon that is compatible with commercially available endoscopes with a minimum working channel inner diameter (ID) of 3.7 mm and maximum length of 100 cm. The modified Catheter is part of a system comprised of three components including a Catheter (sterile, single use), Handle (non-sterile, reusable), and Cartridge (non-sterile, single use). The modified device is used to ablate unwanted tissue by application of extreme cold. The balloon at the distal end of the Catheter is comes in contact with tissue and is inflated with nitrous oxide. Tissue is visualized through the pre-inflated balloon, and the treatment site is selected is by adjusting the endoscope and Handle.

The Boa Endoscopic Valve™ is intended to provide access for endoscopic device passage and exchange throughout the endoscopic procedure.

The Boa Endoscopic Valve™ is used with endoscopes and endoscopic devices with a maximum outer diameter up to 0.167 in. Endoscopic devices are inserted through the Boa Endoscopic Valve™ and through the endoscope. The Boa Endoscopic Valve™ forms a seal around endoscopic devices, supports the endoscopic device, and maintains the position relative to the endoscope biopsy channel port. It is compatible with biopsy port valves and is positioned against the biopsy valve of the endoscope. The Boa Endoscopic Valve™ is non-sterile and is designed for single patient use.

The Coldplay CryoBalloon Ablation System is intended to be used as a cryosurgical tool for the destruction of unwanted tissue in the field of general surgery, specifically for endoscopic applications.

The modified device is a cryosurgical unit with a nitrous oxide cooled balloon probe that is intended for use with commercially available endoscopes with a minimum working channel inner diameter (ID) of 3.7 mm. It is comprised of three components including a Catheter (sterile), Handle (non-sterile), and Cartridge (non-sterile). The modified device is used to destroy unwanted tissue by application of extreme cold to either a 360° circumference or a 90° circumference. The balloon probe at the end of the catheter is inflated with nitrous oxide gas and comes in contact with tissue. Tissue is visualized through the pre-inflated balloon, and the treatment site is selected is by manipulation of the endoscope and Handle. The liquid nitrous oxide spray ablates the unwanted tissue. Nitrous oxide is fully contained within the balloon probe and does not directly contact the tissue. The nitrous oxide gas exits the patient through the Catheter lumen and exhausts out the Handle.
