Intended Use

The Langston dual lumen catheter is indicated for delivery of contrast medium in angiographic studies and for simultaneous pressure measurement from two sites. This type of pressure measurement is useful in determining transvalvular, intravascular, and intraventricular pressure gradients.

Device Story

The Langston dual lumen catheter is a diagnostic intravascular device used by clinicians in angiographic procedures. It features a coaxial design with an inner braided shaft and an outer lumen, allowing for the simultaneous delivery of contrast media and pressure monitoring from two distinct anatomical sites. The device is operated by a physician to assess pressure gradients across valves or within vessels/ventricles. The output consists of real-time pressure data and angiographic images, which assist the clinician in diagnosing cardiovascular conditions. The device is intended for single use and is supplied sterile.

Clinical Evidence

No clinical data was performed. Substantial equivalence is supported by bench testing and biocompatibility testing conducted in accordance with ISO 10993-1. Bench tests included package integrity, simulated anatomy tortuosity, pressure monitoring, flow rate, tensile force, torque strength, air/liquid leakage, dimensional analysis, and hub luer taper. Biocompatibility testing included cytotoxicity, sensitization, irritation, acute systemic toxicity, pyrogenicity, and hemocompatibility. All tests met acceptance criteria.

Technological Characteristics

Dual lumen diagnostic intravascular catheter. Materials include braided shaft and Nylon 12 Grilamid (manifold). Sterilized via ethylene oxide. Single-use. Features pigtail or multipurpose tip configurations. Dimensions vary by model (6F-7F outer diameter, 4F-5F inner diameter, 100-125 cm length). Pressure rated up to 1200 psi.

Indications for Use

Indicated for patients requiring angiographic contrast delivery and simultaneous dual-site pressure measurement to determine transvalvular, intravascular, or intraventricular pressure gradients.

Regulatory Classification

Identification

Dear Jake Schultz:

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. 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 requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

{1}------------------------------------------------

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

#### Device Description

The Langston dual lumen catheter consists of a coaxial tube (outer lumen) mounted over a braided catheter shaft (inner lumen) and an extension line with a 3-way stopcock. The extension line with stopcock connects to the outer lumen. The outer lumen, and extension line are joined by an over molded manifold. The manifold also includes a luer that connects to the inner lumen. The manifold is printed with the Langston catheter length, French size, maximum guidewire diameter, and product logo ("Langston"). The Langston dual lumen catheter tip terminates in either a pigtail or multipurpose tip configuration.

## Intended Use

The Langston dual lumen catheter is indicated for delivery of contrast medium in angiographic studies and for simultaneous pressure measurement from two sites. This type of pressure measurement is useful in determining transvalvular, intravascular, and intraventricular pressure gradients.

## Technological Characteristics Comparison

The Langston dual lumen catheter has identical indications for use and principle of operation as the predicate devices and they are all diagnostic intravascular catheters. The subject and predicate devices are intended for delivery of contrast medium in angiographic studies and for simultaneous pressure measurement from two sites. The Langston dual lumen catheter is equivalent in design and technological characteristics to the predicate devices. The subject and predicate devices are dual lumen catheters sterilized via ethylene oxide and intended for single use. The proximal manifold of the Langston dual lumen catheter will be modified to remove the adhesive bonds and replace it with an over molded proximal manifold component. The manifold component introduces Nylon 12 Grilamid as a new material to the Langston dual lumen catheter. The extension line tubing material of the Langston dual lumen catheter will also be modified to increase stiffness and to remove the adhesive bond by including an additional strain relief.

#### Substantial Equivalence and Summary of Studies

The technological differences between the subject and predicate devices have been evaluated through biocompatibility and bench tests to provide evidence of Langston dual lumen catheter substantial equivalence. Clinical testing was not performed to validate the performance of the subject device. The Langston dual lumen catheter is substantially equivalent to the specified predicate devices based on comparisons of the device functionality, technological characteristics, and indications for use. The device design has been verified through the following tests:

- . Package Integrity
- . Tortuosity in Simulated Anatomy
- Pressure Monitoring
- Flow Rate vs. Injection Pressure ●
- . Tensile Force
- Torque to Failure
- Air Leakage During Aspiration ●
- . Liquid Leakage Under Pressure
- . Torque Strength
- Dimensional Analysis ●
- . Hub Luer Taper

{5}------------------------------------------------

Device samples passed the following biocompatibility tests performed in accordance with ISO 10993-1:

- . Cytotoxicity
- Sensitization .
- Irritation ●
- Acute Systemic Toxicity ●
- . Pyrogenicity
- Hemocompatibility

The results of the verification tests met the specified acceptance criteria and did not raise new safety or performance issues. Therefore, the Langston dual lumen catheter is substantially equivalent to the predicate devices.
