Intended Use
The MultiStage Balloon Dilatation Catheters are indicated for use in adult and adolescent populations to endoscopically dilate strictures of the alimentary tract. Also indicated in adults for endoscopic dilatation of the Sphincter of Oddi with or without prior sphincterotomy.
Device Description
The MultiStage Balloon Dilatation Catheters are indicated for use to endoscopically dilate strictures of the alimentary tract and the Sphincter of Oddi with or without prior sphincterotomy. It consists of an inflatable balloon on a catheter shaft with multiple lumens for inflation and passage of a guidewire. The MultiStage balloon is designed with three-in-one technology and provides successive, gradual dilation of strictures. The balloon is made of Pebax material. The MultiStage Balloon Dilatation is designed to pass over a 0.035in (0.89mm) guidewire through its guidewire lumen or through an minimum working channel of a 2.8mm alimentary tract, or a 3.7mm biliary tract. The hub is made of polycarbonate (PC). Two radiopaque tantalum marker bands are positioned within the balloon shoulders to provide visual reference points fluoroscopically for balloon positioning within the stricture. Accordingly, product models, are divided into those with a wireguided (MSW) and non-wireguided (MSO) component. The MSW model allows the guidewire and catheter to be introduced into the endoscope together. The MSO model as a traditional operation method, the guidewire is first inserted into the endoscope for positioning and then the catheter is inserted through the guidewire for good passability. The physician can choose the model as needed.

No
The device description focuses on mechanical components and functionality for dilation, with no mention of AI or ML. The "Mentions AI, DNN, or ML" section explicitly states "Not Found".

Yes
The device is used to dilate strictures in the alimentary tract and Sphincter of Oddi, which directly treats a medical condition.

No

The device is indicated for dilating strictures, which is a therapeutic intervention, not a diagnostic one.

No

The device is a physical medical device consisting of a catheter with an inflatable balloon, guidewire lumen, and radiopaque markers. It is not solely software.

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

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used to provide information for diagnosis, monitoring, or screening.
  • Device Function: The MultiStage Balloon Dilatation Catheter is a medical device used within the body (in vivo) to physically dilate strictures in the alimentary tract and Sphincter of Oddi. It is a therapeutic device, not a diagnostic test performed on a sample.
  • Intended Use: The intended use clearly states "to endoscopically dilate strictures," which is a physical intervention, not a diagnostic process.
  • Device Description: The description details the physical components and mechanism of action (inflatable balloon, catheter, guidewire, radiopaque markers) which are consistent with an interventional medical device.

Therefore, the MultiStage Balloon Dilatation Catheter is a therapeutic medical device used for in-vivo procedures, not an in-vitro diagnostic device.
