The device description clearly states it is a "Bipolar Loop Electrode," which is a physical hardware component used in electrosurgical procedures.
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.
- Device Description and Intended Use: The description clearly states that the Valley Forge bipolar loop electrodes are designed for electrosurgical excisions in gynecological procedures. This involves using electrical energy to cut or remove tissue directly from the patient's body during a surgical procedure.
- Lack of In Vitro Testing: There is no mention of the device being used to test samples outside of the body.
Therefore, this device falls under the category of a surgical instrument used for direct intervention on the patient, not for in vitro diagnostic testing.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The document references previous use and studies of bipolar electrosurgery and bipolar loops in neurosurgery and gynecological procedures. Dr. Leonard I. Malis used bipolar loops to core brain and spinal cord neoplasms, noting bloodless removal and no damage to contiguous tissues or specimens. Dr. Martin Weisberg's Thomas Jefferson University Hospital Study concludes that "Bipolar loop excision allows for adequate specimens to be obtained with minimal blood loss and short operating time." He also stated a primary benefit as safety due to no grounding pad or insulated speculum needed.

(a)
Identification. A gynecologic electrocautery is a device designed to destroy tissue with high temperatures by tissue contact with an electrically heated probe. It is used to excise cervical lesions, perform biopsies, or treat chronic cervicitis under direct visual observation. This generic type of device may include the following accessories: an electrical generator, a probe, and electrical cables.(b)
Classification. Class II (performance standards).

SUMMARY OF SAFETY AND EFFECTIVE INFORMATION
Valley Forge Scientific Corp, the manufacturer of several Malis bipolar coagulation/cutting systems, now plans to introduce Bipolar Loop Electrodes for gynecological procedures. As the world's foremost authority on binolar electrosurgery Dr. Leonard I. Malis has used bipolar loops to core all types of brain and spinal cord neoplasms such as meningiomas, and gliomas bloodlessly, while the contiguous tissues remain functioning normally, and the removed specimens show no damage whatsoever. Dr. Malis further states that "Bipolar cutting loops restrict cutting current to the very small space between the paired loops. There is no current flow outside of the loops to any other tissues and no current to any ground. Accordingly, there is no heat spread."
Bipolar electrosurgery has been used successfully to cut tissue or coagulate blood vessels for over 30 years. Dr. Malis says that "Bipolar cutting loops have been used in neurosurgery since 1981, and have made possible the safe and complete removal of tumors previously considered unresectable ... The use of these bipolar loops has produced excellent pathology specimens in a wide variety of benign and malignant tumor types, without the confusing thermal damage produced by monopolar loops."
In his Thomas Jefferson University Hospital Study, Dr. Martin Weisberg concludes that "Bipolar loop excision allows for adequate specimens to be obtained with minimal blood loss and short operating time. Because of the characteristics of bipolar loop excision may represent a safer treatment for CIN because no grounding pad or insulated speculum is required for bipolar procedures." In a recent Philadelphia Business Journal (August 8-14, 1997) article, Dr. Weisberg said "The main thing about bipolar technology is the safety issue... the bipolar technology is much safer."

Some of the effective safety features of Bipolar Electrosurgery are:
-
- Bipolar Technology eliminates the need for grounding pads and the possibility of patient burns.
-
- Bipolar Coagulation minimizes damage to adjacent tissue since the patient is no longer the return path for the electrical current.
-
- Bipolar Technology works at voltages approximately 1/4th the voltage required for monopolar technique.
-
- Localized Bipolar Coagulation gives the surgeon precise control of the electric current at the tissue site.
-
- The system's patented waveform and exceedingly low output impedance provide superior coagulation and the absence of charring and sticking even in a dry field.
-
- Because of the high output impedance of monopolar and other bipolar systems, instruments short-out in an irrigated or bloody field.
-
- Unlike monopolar systems, bipolar electrosurgery provides smooth, progressive coagulation with the option of precise, flow-controlled irrigation.
-
- Bipolar technology permits the physician to coagulate in an irrigated field thereby minimizing heat build-up or thermal damage to adjacent tissues.
-
- The waveform parameters of the Valley Forge Bipolar Electrosurgery Systems are programmed for the smoothest, most gentle, precise and efficient cutting and coagulation of tissue during any surgical procedure.
