HEPARIN DOSE RESPONSE CONTROLS, MODEL 306-20 POR

{0} SPECIAL 510(k): Device Modification ODE Review Memorandum (Decision Making Document is Attached) To: THE FILE RE: DOCUMENT NUMBER K051040 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. HMS Coagulation System Heparin Dose Response (HDR) Controls, K043080 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 modification of the pass/fail range and increase of the control preparation rehydration time. 4. Comparison Information (similarities and differences) to applicant's legally marketed predicate device including, labeling, intended use, physical characteristics, sample requirements, methodology, and performance. | Name | HDR Controls K043080 | HDR Control | | --- | --- | --- | | Indication for use | The Heparin Dose Response (HDR) controls are used to verify the performance of HDR cartridges and the HMS Plus Instrument | Same | | Instrument | HMS and HMS Plus | Same | | Raw Material | Sheep Plasma | Same | | Diluent | Hexadimethrine Bromide Solution | Same | | Cartridge | HDR | Same | | Pass/Fail Criteria | Clot time ratio range (pass) Control 1: ≥1.10 to ≤ 3.60 Control 2: ≥1.10 to ≤ 2.60 | Clot time ratio range (pass) Control 1: ≥1.08 to ≤ 5.10 Control 2: ≥1.08 to ≤ 4.60 | | Rehydration Time | 3 minutes | 5 minutes | 5. A Design Control Activities Summary (Appendix G) 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 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 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, 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. 6. A Truthful and Accurate Statement, a 510(k) Summary or Statement and the Indications for {1} 2 # Use Enclosure (and Class III Summary for Class III devices). 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. | (Reviewer's Signature) | 5/11/05 (Date) | | --- | --- | Comments revised:8/1/03 {2} 3
