No
The description focuses on the mechanical and electrical components of the device (needles, generator, deployment mechanism) and does not mention any computational or algorithmic features indicative of AI/ML. The "Mentions AI, DNN, or ML" section explicitly states "Not Found".
Yes
The device is intended for the treatment of symptoms due to urinary outflow obstruction secondary to benign prostatic hyperplasia (BPH), indicating a therapeutic purpose to alleviate a medical condition.
No
The device is described as a treatment device for BPH, specifically for delivering energy to ablate prostatic tissue. Its stated purpose is "treatment of symptoms" and "ablation," not diagnosis or detection of a condition.
No
The device description clearly details physical components like a hand piece, needle electrodes, a disposable cartridge, and a reusable handle, indicating it is a hardware device.
No, 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 Cobra Hand Piece is a surgical instrument used to deliver radiofrequency energy directly to prostatic tissue within the body. It is a therapeutic device, not a diagnostic test performed on a sample outside the body.
- Intended Use: The intended use clearly states it's for the "treatment of symptoms due to urinary outflow obstruction secondary to benign prostatic hyperplasia (BPH)". This is a therapeutic application, not a diagnostic one.
Therefore, based on the provided information, the Cobra Hand Piece is a medical device used for treatment, not an in vitro diagnostic device.
