Indications for Use

Cardia-Cath catheter is used to monitor combined pressure and electrical impedance (volume) in the cardiovascular system.

Device Story

Cardia-Cath is a disposable, sterile pressure-volume catheter transducer. It features one or two pressure transducers and a series of electrodes along its distal segment. The device is inserted into the cardiovascular system to monitor pressure and electrical impedance (volume). It terminates in a single electrical connection at the proximal end. The device is used by clinicians to obtain cardiovascular data. It is substantially equivalent to the Millar SPC-550 model, with modifications to the connector configuration, electrode material, and mounting methodology. Verification testing confirmed safety and efficacy, including biocompatibility, sterility, and transportation integrity.

Clinical Evidence

Bench testing only. Testing included biocompatibility (cytotoxicity, sensitization, irritation, systemic toxicity, haemocompatibility, thrombogenicity in dogs), sterility validation (EtO-Overkill), packaging integrity (ASTM D4169-08), and accelerated aging (ASTM F1980-07). All tests met acceptance criteria.

Technological Characteristics

Disposable, sterile pressure-volume catheter transducer. Features pressure transducers and electrodes for impedance measurement. Sterilization via EtO (ANSI/AAMI ISO 11135). Packaging uses Tyvek. Biocompatibility per ISO 10993-1. Transportation testing per ASTM D4169-08. Accelerated aging per ASTM F1980-07.

Indications for Use

Indicated for monitoring combined pressure and electrical impedance (volume) in the cardiovascular system.

Regulatory Classification

Identification

A catheter tip pressure transducer is a device incorporated into the distal end of a catheter. When placed in the bloodstream, its mechanical or electrical properties change in relation to changes in blood pressure. These changes are transmitted to accessory equipment for processing.

> requirements and complied with BP-22 standard requirements. Two deviations from the legally marketed device specifications have been identified. These deviations have no impact on safety or efficacy. These deviations are:

- Temperature Error Band at Zero Pressure relaxed o from 3.24 mmHg to 3.5 mmHG.
- Sensitivity Error Band" relaxed from 3.16% to o 3.5%.

The modified device IFU includes the new values for the end user to be able to obtain same level of data accuracy. The final report has been reviewed and approved by qualified individuals.

- Transportation testing was performed on the fully packaged finished product of the modified device, Cardia-Cath by DDL. The test was performed in accordance with ASTM D4169-08. Samples passed all tests including bubble leak test and packaging integrity. DDL report No: 1009057 Rev. A is available for review. Then the catheters were tested for functionality to ensure no impact on the device functionality (safety and effectiveness) from transportation testing. This verification test was performed in accordance with Millar reference VRP-2010-0423-01 VAL-180.
- Biocompatibility 트
- . Biocompatibility testing was performed through Nelson Labs. Testing included all requirements per ISO 10993-1 for External communication device, circulating blood, contact duration A-Limited (<24hrs), which includes Cytotoxicity, Sensitization, Irritation or Intracutaneous reactivity, Systemic toxicity (acute), and Haemocompatibility. Samples of the legally marketed device and the modified device were sent to Nelson Laboratories to perform the required tests following GLP requirements. Nelson Labs analysis determined that the Cardia-Cath (modified device) was statistically similar, and therefore substantially equivalent, to the predicate (legally marketed) device, Model SPC-550. Test reports are available for FDA review, if required. The test reports are:
- o Modified ASTM Hemolysis (Direct Contact Method) GLP Report # 538955
- Partial Thromboplastin time (PTT) test GLP Report o # 538954
