The summary describes a device that measures blood pressure using a fiber optic pressure transducer and displays the data. There is no mention of AI, ML, or any algorithms that would process the data beyond simple display or calculation of standard blood pressure metrics. The performance studies focus on physical and biological compatibility, not algorithmic performance.
No.
Explanation: The device is intended to facilitate the introduction of diagnostic and interventional devices and to continuously measure blood pressure, which are diagnostic and procedural assistance functions, not therapeutic.
No
The device is intended to facilitate the introduction of diagnostic and interventional devices and to continuously measure blood pressure. While it measures a physiological parameter (blood pressure), its primary use is for monitoring during procedures and assisting in the access for other devices, rather than diagnosing a condition itself. The "Intended Use / Indications for Use" section states it facilitates the introduction of diagnostic devices, implying it is not a diagnostic device itself.
No
The device description clearly states that the system includes a physical sheath with an integrated fiber optic pressure transducer, a vessel dilator, and a guidewire, in addition to the Blood Pressure Monitor. These are all hardware components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "facilitate the introduction of diagnostic and interventional devices into the vasculature and to continuously measure blood pressure during the procedure". This describes a device used in vivo (within the body) for access and physiological monitoring.
- Device Description: The description details an introducer sheath with an integrated pressure sensor, a dilator, and a guidewire. These are all components used for accessing and working within the vascular system of a living patient.
- Function: The primary function described is to provide vascular access and measure blood pressure in vivo.
In Vitro Diagnostics (IVDs) are devices intended for use in the examination of specimens derived from the human body (such as blood, urine, or tissue) to provide information for diagnostic, monitoring, or compatibility purposes. This device does not perform any analysis on specimens outside of the body.

Device Description
The Endophys Pressure Sensing Sheath Kit is comprised of the Endophys Pressure Sensing Sheath, vessel dilator and guidewire. The Endophys Pressure Sensing Sheath and accessories are provided sterile (EO).
The Pressure Sensing Sheath ("PSS") is an introducer sheath with an integrated fiber optic pressure transducer. The PSS is provided with a dilator and a guidewire, which together make up the Endophys Pressure Sensing Sheath Kit ("PSS Kit"). The PSS Kit is intended to be used only with the Endophys Blood Pressure Monitor ("BPM"), which connects to the PSS and displays the blood pressure measurements. Together with the BPM, the PSS is used to continuously monitor patient blood pressure during procedures requiring vascular access.
The PSS introducer sheath is used to assist vascular access in the same manner as do standard catheter introducers. The PSS introducer sheath has an integrated pressure sensor that provides high resolution, continuous and instantaneous pulse wave hemodynamics to monitor blood pressure. Together, the Pressure Sensing Sheath and the Blood Pressure Monitor comprise the Endophys Pressure Sensing Access System (PSASTM).
The vessel dilator is used to facilitate insertion of the PSS, and is packaged with the Endophys PSS Kit. Once the PSS has been properly positioned in the vessel, the dilator is removed.
The guidewire is J tipped, 50cm (length), 0.89mm (diameter), and is used to assist in the placement of the dilator/PSS Introducer Sheath through the skin and into the vasculature. Once the dilator and introducer are positioned over the guidewire, the guidewire is removed through the dilator.

VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE
Introducer catheters, by nature, are tubular structures intended to provide a pathway for therapeutic and/or diagnostic devices into the human vasculature. Specialized introducer catheters have been developed which incorporate sensors into these devices to allow active monitoring of blood pressure during interventional procedures. Blood pressure monitoring using a fiber optic transducer is the technological principle for both the subject and predicate devices. The technology requires use of a compatible blood pressure monitor to provide this data to the clinician.
At a high level, the subject and predicate device are based on the following same technological elements:
| • Product Code | • UV Adhesive | |
|---|---|---|
| • Device Classification Name | • Pressure Sensor Type | |
| • 21 CFR Regulation Number | • Sensor Location | |
| • Indications for Use | • Pressure Range | |
