Intended Use
Encision's Suction Irrigation Electrodes and Adapters are intended for evacuation of body fluids and to cut and coagulate tissue through a trocar cannula for various general surgical laparoscopic procedures.
Device Description
The Suction Irrigation Electrodes and Adapters combine AEM shielding technology with suction and irrigation of fluids during laparoscopic electrosurgery to cut and coagulate tissue. The electrodes connect to a compatible electrosurgical generator via an adapter on the ENCISION AEM Monitor. The AEM Monitoring System, with compatible electrosurgical instruments, is designed to minimize the likelihood of stray energy injuries caused by active insulation failure or capacitive coupling. The monitor does this by shutting down the ESU when excessive current is returned via the shield circuit which extends to near the tip of the electrode. The electrode has a stainless electrode tip welded onto the distal ID of the active tube. The active tube acts as the suction and irrigation path. The tube assembly has primary and secondary insulation layers which separate the inner active tube from the outer shield tube. The device has a molded body that interfaces with the 30 party trumpet valves or luer valves via the appropriate adapter. The Adapters (sold separately) are attached to the body of the electrode to make a compatible connection with selected suppliers of trumpet valve/tube sets. There is an electrical connector on the body capable of accepting Encision AEM cords, which carry the active and AEM shield conductors. The electrode has various fixed tips at the distal end for surgical manipulation and delivery of electrosurgical energy to the patient. All tip styles are insulated from the end of the active tube to the working portion of the tip. There is a sliding sheath outside of the tube assembly. The sheath in the extended position minimizes risk of injury to tissue from tips when the electrode is inserted into a trocar cannula or reoriented. Holes in the distal end of the tube facilitate suction when the sheath is extended. When the sheath is retracted the electrode tip is exposed for delivery of electrosurgical energy. The sheath can be locked into place in the extended position, and has tactile stops in both the extended and retracted positions. The sheath is required for full protection from stray energy.
More Information

Not Found

No
The description focuses on the device's mechanical and electrical components, specifically AEM shielding technology and electrosurgical energy delivery, with no mention of AI or ML.

Yes
The device is described as cutting and coagulating tissue, which directly treats a condition (e.g., stopping bleeding or removing tissue). The AEM monitoring system also minimizes the likelihood of stray energy injuries.

No

The device is an electrosurgical instrument designed for cutting, coagulating, suction, and irrigation of tissue during laparoscopic procedures. While it includes a monitoring system to minimize stray energy injuries, its primary function is surgical intervention, not diagnosis. The performance studies focus on electrical and fluid flow characteristics, not diagnostic accuracy.

No

The device description clearly details physical components like electrodes, tubes, insulation layers, a molded body, adapters, and a sliding sheath. It also describes bench testing related to electrical continuity, capacitance, energy transmission, and fluid flow, all indicative of a hardware device. While it interacts with a monitor system, the core device itself is a physical instrument.

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

Here's why:

  • Intended Use: The intended use clearly states the device is for "evacuation of body fluids and to cut and coagulate tissue through a trocar cannula for various general surgical laparoscopic procedures." This describes a surgical instrument used in vivo (within the body) during a procedure.
  • Device Description: The description details a surgical electrode with features for electrosurgery, suction, and irrigation, designed to be used with an electrosurgical generator and inserted through a trocar. This is consistent with a surgical device, not a device used to test samples in vitro (outside the body).
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.) in vitro to provide diagnostic information. The device's function is entirely focused on performing a surgical action on tissue within the patient.

Therefore, the Encision Suction Irrigation Electrodes and Adapters are surgical devices, not IVDs.

Reason for_510(k) Submission:

Accumulated changes in design and materials of the Suction Electrodes and Adapters raised new issues of safety and efficacy that required testing to confirm the devices were substantially equivalent to the original Encision device and/or predicate devices in commercial distribution. The original 510(k) submission did not have an explicit indications for use statement. Wording based on the original submission and predicate devices is provided.

Description of Device:

The Suction Irrigation Electrodes and Adapters combine AEM shielding technology with suction and irrigation of fluids during laparoscopic electrosurgery to cut and coagulate tissue. The electrodes connect to a compatible electrosurgical generator via an adapter on the ENCISION AEM Monitor.

1

The AEM Monitoring System, with compatible electrosurgical instruments, is designed to minimize the likelihood of stray energy injuries caused by active insulation failure or capacitive coupling. The monitor does this by shutting down the ESU when excessive current is returned via the shield circuit which extends to near the tip of the electrode.

The electrode has a stainless electrode tip welded onto the distal ID of the active tube. The active tube acts as the suction and irrigation path. The tube assembly has primary and secondary insulation layers which separate the inner active tube from the outer shield tube.

The device has a molded body that interfaces with the 30 party trumpet valves or luer valves via the appropriate adapter. The Adapters (sold separately) are attached to the body of the electrode to make a compatible connection with selected suppliers of trumpet valve/tube sets. There is an electrical connector on the body capable of accepting Encision AEM cords, which carry the active and AEM shield conductors.

The electrode has various fixed tips at the distal end for surgical manipulation and delivery of electrosurgical energy to the patient. All tip styles are insulated from the end of the active tube to the working portion of the tip.

There is a sliding sheath outside of the tube assembly. The sheath in the extended position minimizes risk of injury to tissue from tips when the electrode is inserted into a trocar cannula or reoriented. Holes in the distal end of the tube facilitate suction when the sheath is extended. When the sheath is retracted the electrode tip is exposed for delivery of electrosurgical energy. The sheath can be locked into place in the extended position, and has tactile stops in both the extended and retracted positions. The sheath is required for full protection from stray energy.

Indications for Use:

Encision's Suction Irrigation Electrodes and Adapters are intended for evacuation of body fluids and to cut and coagulate tissue through a trocar cannula for various general surgical laparoscopic procedures.

Contraindications:

These instruments are not intended for use when laparoscopic electrosurgical techniques are contraindicated.

These instruments have not been shown to be effective for tubal sterilization procedures, and should not be used for these procedures.

Technological Characteristics:

The Encision Suction Irrigation Electrodes and Adapters incorporate the same technological characteristics as the predicate devices for delivery of the ESU high frequency current, consisting of insulated conductors and shafts with appropriately shaped tips for electrosurgery.

Like the Encision predicate device, the electrodes include an additional AEM shielding function which diverts stray energy from the shaft of the instrument and is monitored by the Encision AEM Monitor.

Non-clinical Performance Testing:

Performance of the devices' AEM technology, delivery of electrosurgical energy, and suction/irrigation flow has been verified by bench testing.
