A therapeutic device is one that treats a disease or condition. This device removes polyps, which is a treatment, but it is not called a 'therapeutic device', it is an instrument used in a therapeutic procedure.
No
This device is used for the removal and/or cauterization of polyps and tissue from within the gastrointestinal tract, which is a therapeutic rather than a diagnostic function.
No
The device description clearly outlines physical components such as a cutting loop, sheath, handle, and electrode connector, indicating it is a hardware device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is the removal and/or cauterization of polyps and tissue from within the gastrointestinal tract. This is a therapeutic and surgical procedure performed directly on the patient's body.
- Device Description: The device is a physical tool (a snare) used to physically interact with and remove tissue. It delivers electrical current for cutting and cauterization.
- Lack of Diagnostic Function: There is no mention of the device being used to analyze samples (like blood, urine, or tissue) in vitro (outside the body) to provide diagnostic information about a patient's health status.
IVD devices are specifically designed to perform tests on samples taken from the body to diagnose diseases or conditions. This device is a surgical instrument used for treatment.
N/A
Intended Use / Indications for Use
The Disposable Polypectomy Snare is used endoscopically in the removal and/or and cauterization of diminutive polyps, sessile polyps, pedunculated polyps and tissue from within the gastrointestinal tract.

Device Description
The Disposable Polypectomy Snare consists of an insertion part and a handle part. The insertion part includes cutting loop(a flexible wire cable), traction wire, and sheath; the handle part includes sheath sleeve, locking sleeve, rotating sleeve, electrode connector, slider and a handle. The cutting loop can be extended and retracted from the Snare's flexible outer sheath using a three ring handle. The cutting loop can also be rotated 360° using the rotating actuator on the handle. The inner diameter of the sheath is PTFE to provide minimal friction during extension, rotation, and retraction of the loop from the sheath. When passed through an endoscope and activated, the Snare delivers a monopolar electrical current to cut and cauterize tissue with the loop.
The Disposable Polypectomy Snare is sterile for single use with no delayed hypersensitivity and no intracutaneous reactivity, have no animal or human origin substance.
The cutting loop of disposable polypectomy snare has four shapes to be used in clinical practice:
Ellipse type (E type), Hexagonal type (H type), Crescent type (C type), Round type (R type), and the loop can extend, retract from the snare's flexible outer sheath.
The materials used for construction of Disposable Polypectomy Snare are typical for this type of medical device. Materials of Cutting Loop is stainless steel 06Cr19Ni10, the Sheath is made of PTEF, the Electrode Connector is made of stainless steel SUS304. The Handle, Slider, Rotating Sleeve and Locking Sleeve are made of ABS, the Sheath Sleeve is made of HDPE.

Table 2- Comparison of Technology Characteristics
7
8
The technological characteristics of the subject device are identical to those of predicate device. The subject device has the same basic design as the predicate device. The comparison between the subject and predicate devices is based on the following:
- Same intended use
- · Same indications for use
- · Similar material types that meet ISO 10993 biocompatibility requirements
- · Same sterilization methods
- Same fundamental technology/principal of operation/user interface
The type of the cutting loop of the subject device is same with those of predicate device, just the expression is in different words, ellipse or oval, the description of same shape.
The compatible electrical surgical generators of the predicate device are not publicly available. The function of the Cutting Loop of the proposed device and the predicate device remains the same in that it is attached to the generator to allow the flow of electrical energy to the cutting loop for the purpose of resecting tissue. The use of the different electrosurgical generator does not change the intended use or fundamental technology of the subject device.
Performance comparison testing was conducted to the predicate device and current device to compare their physical performance.
It can be found the subject device incorporates substantially equivalent device materials, design, configuration, fundamental technology, sterilization process and intended use as those featured in the predicate device.
10.0 Conclusion
The conclusions drawn from the comparison and analysis above demonstrate that the proposed device is as safe, as effective, and performs as well as the legally marketed predicated device in K172758 and raises no new questions of safety or effectiveness. The differences between both devices are insignificant in terms of safety and effectiveness.
