Indications for Use
The Heparin Dose Response (HDR) Cartridge is intended for use with the Hepcon HMS system to measure the heparin dose response of a patient's blood. It is intended for use in a clinical setting by trained healthcare professionals.
Device Story
The Heparin Dose Response (HDR) Cartridge is an in vitro diagnostic consumable used with the HMS Plus instrument. It processes whole blood samples to measure individual patient responses to heparin. The device modification involves a 13.6% increase in porcine-derived USP heparin concentration within the cartridge channels. The cartridge functions as part of an automated heparin analyzer system, typically used in clinical settings to guide anticoagulation management. Healthcare providers use the resulting data to assess heparin sensitivity, which informs clinical decisions regarding heparin dosing during procedures requiring anticoagulation. The device provides quantitative output to assist in patient-specific heparin therapy.
Clinical Evidence
Bench testing only. Verification testing was conducted to confirm performance of the modified cartridges containing revised USP heparin concentrations. Data from this testing was used to update applicable tables in the Instructions for Use.
Technological Characteristics
Single-use cartridge for Hepcon HMS system. Contains heparinized channels (1-4) with revised USP heparin concentrations (2.84 units/mL and 1.7 units/mL). Fundamental sensing technology unchanged from predicate.
Indications for Use
Indicated for patients requiring heparin anticoagulation monitoring during procedures where heparin is administered. No specific age or gender contraindications provided.
Regulatory Classification
Identification
An automated heparin analyzer is a device used to determine the heparin level in a blood sample by mixing the sample with protamine (a heparin-neutralizing substance) and determining photometrically the onset of air-activated clotting. The analyzer also determines the amount of protamine necessary to neutralize the heparin in the patient's circulation.
Special Controls
*Classification.* Class II (special controls).

SPECIAL 510(k): Device Modification
Review Memorandum
To: THE FILE
RE: DOCUMENT NUMBER k102953
This 510(k) submission contains information/data on modifications made to the SUBMITTER'S own Class II, Class III or Class I devices requiring 510(k). The following items are present and acceptable (delete/add items as necessary):
1. Heparin Dose Response (HDR) Cartridge, k042070 previously cleared device.
2. Submitter's statement that the INDICATION/INTENDED USE of the modified device as described in its labeling HAS NOT CHANGED along with the proposed labeling which includes instructions for use, package labeling, and, if available, advertisements or promotional materials (labeling changes are permitted as long as they do not affect the intended use).
3. A description of the device MODIFICATION(S), including clearly labeled diagrams, engineering drawings, photographs, user's and/or service manuals in sufficient detail to demonstrate that the FUNDAMENTAL SCIENTIFIC TECHNOLOGY of the modified device has not changed.
This change was for the HDR cartridge, replacing the old United States Pharmacopoeia (USP) heparin with revised USP heparin due to the heparin monograph change. The heparin concentrations have been increased by 13.6% for heparinized channels (ch 1 & 2 and ch 3 & 4).
4. Comparison Information (similarities and differences) to applicant's legally marketed predicate device including, labeling, intended use, physical characteristics, and sample requirements. The difference is a change in heparin concentration in channels 1 & 2 from 2.5 to 2.84 units/mL and channels 3 & 4 from 1.5 to 1.7 units/mL.
5. A Design Control Activities Summary which includes:
a) Identification of Risk Analysis method(s) used to assess the impact of the modification on the device and its components, and the results of the analysis. (see page 20)
b) Based on the Risk Analysis, an identification of the verification and/or validation activities required, including methods or tests used and acceptance criteria to be applied. (see page 21)
c) A declaration of conformity with design controls. The declaration of conformity should include:
i) A statement signed by the individual responsible, that, as required by the risk analysis, all verification and validation activities were performed by the designated individual(s) and the results demonstrated that the predetermined acceptance criteria were met, (see page 22) and
ii) A statement signed by the individual responsible, that the manufacturing facility is in conformance with design control procedure requirements as specified in 21 CFR 820.30 and the records are available for review. (see page 22)
6. A Truthful and Accurate Statement, a 510(k) Summary and the Indications for Use Enclosure. (see page 27)
The labeling for this modified subject device has been reviewed to verify that the indication/intended use for the device is unaffected by the modification. In addition, the submitter's description of the particular modification(s) and the comparative information between the modified and unmodified devices demonstrate that the fundamental scientific technology has not changed. The submitter has provided the design control information as specified in The New 510(k) Paradigm and on this basis, I recommend the device be determined substantially equivalent to the previously cleared (or their preamendment) device.
