System comprises a main unit with internal heater, touchscreen monitor, and single-use IPH Procedure Kit (heat exchanger, fluid reservoir, tubing, temperature probes, suction guards, pressure sensor). Unit warms distilled/sterile water, which transfers heat to the perfusion solution via the heat exchanger. Warmed solution is pumped to the patient and returned to the reservoir. Used in clinical settings by healthcare providers to maintain target peritoneal temperature. Redesigned from HT-1000 for smaller footprint, improved component availability, and updated touchscreen interface. Output allows clinicians to monitor and control hyperthermia therapy, potentially benefiting patients by facilitating localized thermal treatment. ## Clinical Evidence Bench testing only. No clinical data. Verification testing included pump settings (pressure, flow rate), water bath heat time/temperature, operating conditions, fluid ingress/overfill/spill tests, software validation, and usability testing. ## Technological Characteristics System includes internal heating unit, touchscreen monitor, and disposable IPH kit. Uses QNX operating system. Connectivity via touchscreen interface. Essential mode of operation: closed-loop fluid heating and circulation. Components redesigned for commercial availability. Sterilization method not specified for unit; IPH kit components are previously cleared. ## Regulatory Identification (1) A peritoneal dialysis system and accessories is a device that is used as an artificial kidney system for the treatment of patients with renal failure or toxemic conditions, and that consists of a peritoneal access device, an administration set for peritoneal dialysis, a source of dialysate, and, in some cases, a water purification mechanism. After the dialysate is instilled into the patient's peritoneal cavity, it is allowed to dwell there so that undesirable substances from the patient's blood pass through the lining membrane of the peritoneal cavity into this dialysate. These substances are then removed when the dialysate is drained from the patient. The peritoneal dialysis system may regulate and monitor the dialysate temperature, volume, and delivery rate together with the time course of each cycle of filling, dwell time, and draining of the peritoneal cavity or manual controls may be used. This generic device includes the semiautomatic and the automatic peritoneal delivery system.(2) The peritoneal access device is a flexible tube that is implanted through the abdominal wall into the peritoneal cavity and that may have attached cuffs to provide anchoring and a skin seal. The device is either a single use peritioneal catheter, intended to remain in the peritoneal cavity for less than 30 days, or a long term peritoneal catheter. Accessories include stylets and trocars to aid in the insertion of the catheter and an obturator to maintain the patency of the surgical fistula in the abdominal wall between treatments. (3) The disposable administration set for peritoneal dialysis consists of tubing, an optional reservoir bag, and appropriate connectors. It may include a peritoneal dialysate filter to trap and remove contaminating particles. (4) The source of dialysate may be sterile prepackaged dialysate (for semiautomatic peritoneal dialysate delivery systems or “cycler systems”) or dialysate prepared from dialysate concentrate and sterile purified water (for automatic peritoneal dialysate delivery systems or “reverse osmosis” systems). Prepackaged dialysate intended for use with either of the peritoneal dialysate delivery systems is regulated by FDA as a drug. ## Special Controls *Classification.* Class II (special controls). The following accessories are exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9: A catheter finger grip that is non-patient contacting and intended for single use with a peritoneal catheter; a continuous ambulatory peritoneal dialysis (CAPD) belt; and a catheter stand that does not include weigh scales. ## Predicate Devices - ThermoChem HT-1000 System ([K993330](/device/K993330.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

This water is circulated around a single-use heat exchanger (included in the IPH Procedure Kit) where it warms Lactated Ringer's (or another physiologically compatible sterile solution) for infusion into the patient's peritoneal cavity. The IPH Procedure Kit contains two temperature probes, two suction guards, and a pressure sensor as well as a Perfusion Kit consisting of a heat exchanger, a fluid reservoir, and tubing set. The warmed Lactated Ringer's (or other physiologically compatible sterile solution) is pumped through the tubing to the patient and then returns to the fluid reservoir. The IPH Procedure Kit is a convenience kit of previously 510(k)-cleared devices that are repackaged / relabeled by ThermaSolutions, Inc. The ThermoChem HT-2000 unit has been redesigned to physically reduce the size of the unit and to allow use of components that are more commercially available. The software and touchscreen monitor user interface have been redesigned to make the device easier to use. The redesigned ThermoChem unit will continue to use the currently-marketed IPH Procedure Kit for use with the ThermoChem HT-1000 System. - The intended use of the ThermoChem™ HT-2000 System is to raise Intended Use: the core temperature of the peritoneum to a desired target temperature by continuously lavaging the peritoneum with circulating and warmed Lactated Ringer's Solution, U.S.P., or another physiologically compatible sterile solution.
