Intended Use
The XO Constrain Percutaneous Transluminal Angioplasty Constraining Catheter is intended to be used in conjunction with a PTA balloon to facilitate dilation and apposition of the scoring/constraining surface to the stenal in the iliac, femoral, ilio-popliteal, infra-popliteal, and renal arteries, and for treatment of obstructive or synthetic arteriovenous dialysis fistulae. Not for use in the coronary or neuro-vasculature.
Device Description
The XO Constrain Percutaneous Transluminal Angioplasty Constraining Catheter is a balloon dilation scoring/constraining catheter. It consists of a metal alloy wire shaft connected to the metal alloy expandable constraining structure (CS) at the distal atraumatic tapered tip. It works with offthe-shelf compliant and semi-compliant balloons to expand the constraining structure and is designed to facilitate uniform, atraumatic balloon expansion, vessel scoring, and rewrap within small or distal vessels and arteries. The XO Constrain catheter is designed to be used with balloons between the sizes of 6 - 20mm in length and 1.5 - 4.0mm in diameter and may work with PTA and peripheral use PTCA balloon catheters with a standard over-the-wire (OTW) or rapid exchange (RX) procedural approaches. The expansion of the CS is determined by the balloon inflation diameter. Upon deflation the CS returns to its original shape and is removed from the vessel along with the balloon catheter. The XO Constrain should not be used in the coronary or neuro-vasculature.
More Information

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

Yes

The device is intended to facilitate dilation and apposition of a scoring/constraining surface to a stenosis in various arteries and for treatment of obstructive or synthetic arteriovenous dialysis fistulae, which are therapeutic medical interventions.

No

Explanation: The device is described as a "Percutaneous Transluminal Angioplasty Constraining Catheter" used to facilitate dilation and apposition, and vessel scoring. Its function is interventional/therapeutic, not diagnostic.

No

The device description clearly outlines a physical catheter with a metal alloy wire shaft and expandable constraining structure, indicating it is a hardware device, not software-only.

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

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information about a person's health. This testing is done outside of the body.
  • Device Function: The description clearly states that the XO Constrain Percutaneous Transluminal Angioplasty Constraining Catheter is used within the body to facilitate dilation and apposition of a scoring/constraining surface to a stenosis in arteries and fistulae. It's a therapeutic device used during a medical procedure.
  • Intended Use: The intended use describes a procedure performed directly on the patient's vascular system, not the analysis of samples.

Therefore, the function and intended use of this device fall outside the scope of an In Vitro Diagnostic device.

Device Description

The XO Constrain Percutaneous Transluminal Angioplasty Constraining Catheter is a balloon dilation scoring/constraining catheter. It consists of a metal alloy wire shaft connected to the metal alloy expandable constraining structure (CS) at the distal atraumatic tapered tip. It works with off-the-shelf compliant and semi-compliant balloons to expand the constraining structure and is designed to facilitate uniform, atraumatic balloon expansion, vessel scoring, and rewrap within small or distal vessels and arteries. The XO Constrain catheter is designed to be used with balloons between the sizes of 6 - 20mm in length and 1.5 - 4.0mm in diameter and may work with PTA and peripheral use PTCA balloon catheters with a standard over-the-wire (OTW) or rapid exchange (RX) procedural approaches.

Dear Spencer Walker:

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 (the 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.
