Intended Use
The NuCath™ Wedge Pressure Catheter is indicated for measuring pressure in the right heart (including central venous pressure, right ventricle pressure, pulmonary artery pressure, and pulmonary artery wedge pressure).
Device Description
The NuCath Wedge Pressure Catheter is an intravascular catheter with a balloon at the distal tip intended to measure pressure in the right heart.
More Information

No
The summary describes a physical catheter for pressure measurement and does not mention any software, algorithms, or data processing that would suggest AI/ML.

No.
The device is used to measure physiological parameters (pressure), not to treat or diagnose a disease.

Yes
The device is indicated for "measuring pressure in the right heart," which provides information that can be used to diagnose various cardiac conditions.

No

The device description clearly states it is an "intravascular catheter with a balloon at the distal tip," indicating it is a physical hardware device, not software only.

Based on the provided information, the NuCath™ Wedge Pressure Catheter is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Function: The NuCath™ Wedge Pressure Catheter is an intravascular catheter used to directly measure pressure within the right heart. This is an in vivo measurement, meaning it's performed inside the living body.
  • Lack of Sample Analysis: The description does not mention the device analyzing any samples taken from the patient. It's a direct measurement tool.

Therefore, the NuCath™ Wedge Pressure Catheter falls under the category of a medical device used for direct physiological measurement, not an in vitro diagnostic.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

A risk analysis per ISO 14971: Medical devices – Application of risk management of medical devices was conducted to assess the risk profile of the subject device. Control mechanisms, including design verification testing, were defined to mitigate the identified risks, to demonstrate that the subject device performs as intended and to evaluate substantial equivalence. Below is a list of non-clinical testing that is included in the submission:

  • Visual Inspection
  • Balloon Preparation
  • Diameter and Profile
  • Radio-detectability
  • Catheter Body Maximum Pressure
  • Hubs/Luers
  • Bond Strength (Peak Tensile Force)
  • Tip Pulling and Torquing
  • Minimum Burst Strength
  • Repeated Balloon Inflation (Balloon Fatigue)
  • Balloon Inflation and Deflation
  • Balloon Deflatability
  • Balloon Distensibility (Compliance)

The following standards were referenced in the testing listed above:

  • ISO 10555-1:2013, Intravascular catheters – Sterile and single-use catheters – Part 1: General requirements [including Amendment 1 (2017)]
  • ISO 10555-4: 2013, Intravascular Catheters - Sterile and single-use catheters - Part 4: Balloon dilation catheters
  • ASTM F640-12, Standard Test Methods for Determining Radiopacity for Medical Use
  • ISO 80369-1: 2018, Small-bore connectors for liquids and gases in healthcare applications - Part 1: General requirements

Dear Jessica Jho:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's
