Intended Use
The WATCHDOG™ Hemostasis Valve is intended to maintain hemostic interventional procedures. The WATCHDOG™ Hemostasis Valve is indicated for maintaining a seal around diagnostic/ interventional devices with combined outer diameters of up to 8F [0.105 in (2.67 mm)] during diagnostic/ interventional procedures. The Insertion Tool is used to facilitate the introduction of a guidewire during general intravascular procedures. The Torque Device is used for guidewire manipulation during general intravascular procedures.
Device Description
The WATCHDOG™ Hemostasis Valve kit includes the WATCHDOG™ Hemostasis Valve, an Insertion Tool and a Torque Device. The WATCHDOG™ Hemostasis Valve is designed to reduce blood loss and to facilitate pressure injections during interventional procedures. This device is intended to maintain hemostasis during the use of diagnostic or interventional devices by maintaining a seal around these devices. The WATCHDOG ™ Hemostasis Valve has two seals; the low-pressure (Proximal) seal and the high-pressure (Distal) seal. The body of the device has two luer fittings, one on the main body and one on the side port. The side port has a female luer fitting and is used for connecting pressure monitoring and manual infusion equipment. The main body has a rotating male luer for connecting to guide or diagnostic catheters. The insertion tool is intended for use at the proximal end of the WATCHDOG™ Hemostasis Valve, which is attached to a guiding catheter hub. The insertion tool is used to facilitate the introduction of a guidewire through the WATCHDOG™ device, into the lumen of a guiding catheter, without damaging the guidewire distal tip. It may also be used to introduce a guidewire into an over-the-wire type balloon dilatation catheter. The Torque Device is a non-patient contacting accessory device used to apply torsional and/or axial force to the guidewire to manipulate its distal end in the vasculature. It is designed to accommodate guidewire with diameters from 0.010 to 0.018 inches.
More Information

No
The device description and performance studies focus on mechanical and material properties, with no mention of AI, ML, or data processing.

No.
The device components are described as maintaining hemostasis, facilitating guidewire introduction, and manipulating guidewires, which are functions that support diagnostic or interventional procedures rather than directly treating a disease or condition.

No

The device, a hemostasis valve, is intended to maintain a seal around diagnostic/interventional devices, not to perform diagnosis itself.

No

The device description clearly outlines physical components (Hemostasis Valve, Insertion Tool, Torque Device) and their mechanical functions. There is no mention of software as part of the device's operation or intended use.

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states the device is for "maintaining hemostatic interventional procedures" and "maintaining a seal around diagnostic/ interventional devices." This describes a device used during a medical procedure on a patient, not a device used to test samples outside the body to diagnose a condition.
  • Device Description: The description details a valve, insertion tool, and torque device used to manage blood loss and facilitate the introduction of devices into the body during procedures. This aligns with the intended use and does not describe a device for analyzing biological samples.
  • Lack of IVD Indicators: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), performing tests in vitro (in a lab setting), or providing diagnostic information based on sample analysis.

Therefore, the WATCHDOG™ Hemostasis Valve Kit is a medical device used in interventional procedures, not an In Vitro Diagnostic device.
