Intended Use
The Sphincterotome is intended to be used in the selective cannulation of the biliary ducts and the transendoscopic sphincterotomy of the Papilla of Vater and/or the Sphincter of Oddi. The device can also be used to inject contrast medium.
Device Description
The proposed device has two types: Sphincterotome / short-wire compatible and Sterile Sphincterotome. Sterile commonly traditional Endoscopic Retrograde Sphincterotome used in Cholangiopancreatography (Hereinafter referred to ERCP) surgery need to be used with a long guidewire, while Sphincterotome / short-wire compatible with short-wire techniques to compatible with a short guidewire to achieve rapid exchange between ERCP devices. The proposed device consists of Cutting Wire, Outer Tube and Handle Assembly. It is used with the High Frequency Generator (Hereinafter referred to HF Generator) and the endoscopic procedures. The HF Generator supplies high frequency energy through the Cutting Wire of the proposed device to cut the tissue at the appropriate power and voltage. The models with injection can inject contrast medium into the biliary ducts. The main materials of the proposed device include PTFE, ABS, SUS304. The proposed device has 52 specifications, which mainly differ in cutting wire type, cutting wire length, preloaded guidewire length and with insulation tube or not. The proposed device Sphincterotome is EO sterilized to achieve the Sterility Assurance Level (SAL) of 10-6 and placed in a sterility maintenance package to ensure a shelf life of 1 year.
More Information

No
The description focuses on the mechanical and electrical components of a surgical tool and does not mention any AI/ML capabilities.

Yes.
The device is used for transendoscopic sphincterotomy, which is a therapeutic procedure involving the cutting of tissue to treat conditions related to the Papilla of Vater and/or the Sphincter of Oddi.

No

The device is primarily used for therapeutic procedures (selective cannulation and sphincterotomy) and for injecting contrast medium, which aids in visualization but is not a diagnostic function of the device itself. While contrast injection can support diagnosis, the device's main role is interventional.

No

The device description clearly outlines physical components (Cutting Wire, Outer Tube, Handle Assembly) made of materials like PTFE, ABS, and SUS304. It also describes sterilization and packaging, indicating a physical medical device, not software only.

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

Here's why:

  • Intended Use: The intended use clearly describes a device used for surgical procedures (cannulation and sphincterotomy) and injecting contrast medium within the body. IVDs are used to examine specimens from the body (like blood, urine, tissue) in vitro (outside the body) to diagnose or monitor conditions.
  • Device Description: The description details a physical device with a cutting wire, outer tube, and handle assembly, used with a high-frequency generator for cutting tissue. This is consistent with a surgical instrument, not an IVD.
  • Anatomical Site: The device is used directly on anatomical sites within the body (biliary ducts, Papilla of Vater, Sphincter of Oddi).
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples, reagents, or any of the typical components or processes associated with in vitro diagnostics.

The device described is a surgical instrument used in endoscopic procedures.
