Intended Use
The pORTAL Steerable Hydrophilic Guidewire and pORTAL EXT Extension Wire is intended for use in the neuro vasculature. The wire can be steered to facilitate the selective placement of diagnostic or therapeutic catheters. This device is not intended for use in peripheral or coronary arteries.
Device Description
The pORTAL Steerable Hydrophilic Guidewire is a disposable medical device designed for single use only. It is designed to selectively introduce and position catheters and other interventional devices within target vessels. In order to achieve this purpose, the guidewire must be capable of being steered through blood vessels. This necessitates pushing and torqueing capability within the product. The design of the distal section of the guides steerability, while maintaining the flexibility necessary to negotiate the tortuous path of the blood vessel network. Coatings are placed on the device to improve the lubricity and ease in its advancement through the guide catheter and the blood vessels. Two accessories are provided within the package. These are a Torquer device and an introducer Needle. Both can be used to aid in the use of the device. The pORTAL EXT Extension Wire is intended to interface with pORTAL Steerable Hydrophilic Guidewire. It is provided sterile and is sold separately in its own packaging configuration. The 115cm extension wire provides a facility to extend the overall length of the pORTAL quidewire to 315cm (see table 1 for dimensional specifications). This enable length to be extended during use to aid with over-the wire exchange. This facilitates introduction and positioning of catheters and other interventional devices within the target anatomy, while the guidewire retains its working position at the location of intervention. The stiffness of the extension wire is comparable to the proximal, unground section of the pORTAL Guidewire.

No
The description focuses on the mechanical properties and intended use of a guidewire and extension wire, with no mention of AI or ML capabilities.

No
The device is described as a guidewire intended to facilitate the placement of diagnostic or therapeutic catheters, not to provide therapy itself.

No

The device description states its purpose is to "selectively introduce and position catheters and other interventional devices within target vessels," and that it "can be steered to facilitate the selective placement of diagnostic or therapeutic catheters." This indicates it's a tool for delivering other devices, not a diagnostic device itself.

No

The device description clearly details physical components like a guidewire, extension wire, torquer, and introducer needle, and the performance studies focus on bench testing of these physical attributes.

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

Here's why:

  • Intended Use: The intended use clearly states that the device is for facilitating the selective placement of diagnostic or therapeutic catheters within the neuro vasculature. This is an interventional procedure performed directly on the patient's body.
  • Device Description: The description details a physical guidewire designed for navigation and positioning within blood vessels. It describes mechanical properties like steerability, flexibility, and lubricity, all related to its function within the body.
  • Lack of In Vitro Activity: There is no mention of the device being used to examine specimens (like blood, tissue, or urine) outside of the body to provide diagnostic information. IVDs are used to perform tests on these types of samples.

The device is a medical device used in vivo (within the living body) for interventional procedures, not an in vitro diagnostic device.

IV. DEVICE DESCRIPTION

The pORTAL Steerable Hydrophilic Guidewire is a disposable medical device designed for single use only. It is designed to selectively introduce and position catheters and other interventional devices within target vessels. In order to achieve this purpose, the guidewire must be capable of being steered through blood vessels. This necessitates pushing and torqueing capability within the product. The design of the distal section of the guides steerability, while maintaining the flexibility necessary to negotiate the tortuous path of the blood vessel network. Coatings are placed on the device to improve the lubricity and ease in its advancement through the guide catheter and the blood vessels. Two accessories are provided within the package. These are a Torquer device and an introducer Needle. Both can be used to aid in the use of the device.

The pORTAL EXT Extension Wire is intended to interface with pORTAL Steerable Hydrophilic Guidewire. It is provided sterile and is sold separately in its own packaging configuration. The 115cm extension wire provides a facility to extend the overall length of the pORTAL quidewire to 315cm (see table 1 for dimensional specifications). This enable length to be extended during use to aid with over-the wire exchange. This facilitates introduction and positioning of catheters and other interventional devices within the target anatomy, while the guidewire retains its working position at the location of intervention. The stiffness of the extension wire is comparable to the proximal, unground section of the pORTAL Guidewire.

VIII. CONCLUSIONS

The pORTAL Steerable Hydrophilic Guidewire and pORTAL EXT Extension Wire has an intended use and technological characteristics equivalent to the predicate devices. The subject device demonstrates product performance through successful bench testing. The pORTAL Guidewire device demonstrates it is safe for use for 2 years 3 months and the pORTAL Extension Wire is safe for 5 years. All packaging tests support the claimed shelf life. Device use is identical to the predicate devices and performance of the new device is comparable.

Taking this information into account, it is concluded that the pORTAL Steerable Hydrophilic Guidewire and pORTAL EXT Extension Wire is substantially equivalent to the predicate devices, the Traxcess 14EX Guidewire and Traxcess Docking Wire (K093397) and Transend EX Guidewire (K934122).
