Intended Use

The Hemocor HPH® Hemoconcentrator is intended for use as an ultrafiltration system to remove excess fluid during and/or following cardiopulmonary bypass procedures where acute hemodilution has been employed.

Device Story

Hemocor HPH 700 is a hemoconcentrator used during or after cardiopulmonary bypass to remove excess fluid from blood. Device consists of glycerin-free, microporous, hollow fiber, polysulfone membrane housed in polycarbonate chamber with polyurethane potting. Includes PVC tubing and polycarbonate adapters for extracorporeal circuit integration. Operates as ultrafiltration system; blood flows through hollow fibers, allowing fluid removal across membrane. Used in clinical settings by medical professionals. Benefits patient by managing fluid balance following hemodilution.

Clinical Evidence

Bench testing only. Performance evaluations included ultrafiltration rate vs. transmembrane pressure, pressure drop vs. blood flow rate, protein rejection, minimum blood flow rate, and blood path integrity.

Technological Characteristics

Materials: Polysulfone membrane, polycarbonate housing, polyurethane potting. Design: Hollow fiber, glycerin-free. Surface area: 0.7 m². Max transmembrane pressure: 500 mmHg. Blood flow rate: 50-500 ml/min. Priming volume: 58 ml. Molecular weight cut-off: 65,000 daltons. Mechanical device; no software or energy source.

Indications for Use

Indicated for patients undergoing cardiopulmonary bypass procedures where acute hemodilution has been employed, requiring removal of excess fluid via ultrafiltration.

Regulatory Classification

Identification

A high permeability hemodialysis system is a device intended for use as an artificial kidney system for the treatment of patients with renal failure, fluid overload, or toxemic conditions by performing such therapies as hemodialysis, hemofiltration, hemoconcentration, and hemodiafiltration. Using a hemodialyzer with a semipermeable membrane that is more permeable to water than the semipermeable membrane of the conventional hemodialysis system (§ 876.5820), the high permeability hemodialysis system removes toxins or excess fluid from the patient's blood using the principles of convection (via a high ultrafiltration rate) and/or diffusion (via a concentration gradient in dialysate). During treatment, blood is circulated from the patient through the hemodialyzer's blood compartment, while the dialysate solution flows countercurrent through the dialysate compartment. In this process, toxins and/or fluid are transferred across the membrane from the blood to the dialysate compartment. The hemodialysis delivery machine controls and monitors the parameters related to this processing, including the rate at which blood and dialysate are pumped through the system, and the rate at which fluid is removed from the patient. The high permeability hemodialysis system consists of the following devices:(1) The hemodialyzer consists of a semipermeable membrane with an in vitro ultrafiltration coefficient (K uf ) greater than 8 milliliters per hour per conventional millimeter of mercury, as measured with bovine or expired human blood, and is used with either an automated ultrafiltration controller or anther method of ultrafiltration control to prevent fluid imbalance.(2) The hemodialysis delivery machine is similar to the extracorporeal blood system and dialysate delivery system of the hemodialysis system and accessories (§ 876.5820), with the addition of an ultrafiltration controller and mechanisms that monitor and/or control such parameters as fluid balance, dialysate composition, and patient treatment parameters (e.g., blood pressure, hematocrit, urea, etc.). (3) The high permeability hemodialysis system accessories include, but are not limited to, tubing lines and various treatment related monitors (e.g., dialysate pH, blood pressure, hematocrit, and blood recirculation monitors).

Special Controls

*Classification.* Class II. The special controls for this device are FDA's:(1) “Use of International Standard ISO 10993 ‘Biological Evaluation of Medical Device—Part I: Evaluation and Testing,’ ” (2) “Guidance for the Content of 510(k)s for Conventional and High Permeability Hemodialyzers,” (3) “Guidance for Industry and CDRH Reviewers on the Content of Premarket Notifications for Hemodialysis Delivery Systems,” (4) “Guidance for the Content of Premarket Notifications for Water Purification Components and Systems for Hemodialysis,” and (5) “Guidance for Hemodialyzer Reuse Labeling.”
