Intended Use

The RF20000a Coblation System, comprised of the FLOW 50 Wand and the RF20000a Controller, is indicated for the resection, ablation, and coagulation of soft tissues and hemostasis of blood vessels in the following arthroscopic and orthopedic procedures: All Joints (Hip, Knee, Shoulder, Wrist, Ankle, Elbow), Hip, Knee, Shoulder, Wrist.

Device Description

The RF20000a Coblation System is an electrosurgical system consisting of a bipolar radiofrequency Controller with Integrated Fluid Outflow Regulator; a sterile, disposable, single-use FLOW 50 Wand; and a non-sterile, reusable Foot Control. This System utilizes bipolar technology specifically designed for the resection, ablation and coagulation of soft tissues and hemostasis of blood vessels in various arthroscopic and orthopedic procedures. The System offers five distinct Modes of operation: Hi (Ablation), Lo (Ablation), Vac (Vacuum), and COAG (Hemostasis). Each Ablation (Coblation) mode allows for precise ablation with minimal damage to surrounding healthy tissue. The COAG mode allows for consistent and precise hemostasis of blood vessels.

AI/ML Overview

Since the provided document is a 510(k) premarket notification for an electrosurgical device rather than an AI/ML medical device, it does not contain the specific information requested in the prompt regarding acceptance criteria and studies for AI/ML performance.

Therefore, I cannot provide:

  1. A table of acceptance criteria and the reported device performance.
  2. Sample size used for the test set or data provenance.
  3. Number of experts used to establish ground truth or their qualifications.
  4. Adjudication method.
  5. MRMC comparative effectiveness study results.
  6. Standalone performance details.
  7. Type of ground truth used.
  8. Sample size for the training set.
  9. How ground truth for the training set was established.

This document focuses on electrical safety, software validation, and tissue effect testing (histology, thermal margins) to demonstrate substantial equivalence to predicate devices, which is typical for electrosurgical devices. It does not involve AI or algorithms that require such performance metrics.

Dear Dr. Dawson:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug. and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you; however, that device labeling must be truthful and not misleading.

Description

RF20000a Coblation System

The RF20000a Coblation System is an electrosurgical system consisting of a bipolar radiofrequency Controller with Integrated Fluid Outflow Regulator; a sterile, disposable, single-use FLOW 50 Wand; and a non-sterile, reusable Foot Control.

{5}------------------------------------------------

This System utilizes bipolar technology specifically designed for the resection, ablation and coagulation of soft tissues and hemostasis of blood vessels in various arthroscopic and orthopedic procedures.

The System offers five distinct Modes of operation: Hi (Ablation), Lo (Ablation), Vac (Vacuum), and COAG (Hemostasis). Each Ablation (Coblation) mode allows for precise ablation with minimal damage to surrounding healthy tissue. The COAG mode allows for consistent and precise hemostasis of blood vessels.

FLOW 50 Wand

The FLOW 50 Wand consists of a handle, shaft, integrated cable, and suction tubing. The integrated cable and suction tubing are attached at the proximal end of the handle and connect to the RF20000a Controller and the Fluid Outflow Regulator, respectively. The handle has finger switches that enable Ablation Mode switching (Lo. Med, Hi) as well as activation of the Wand (Vac, Coag, or Ablate). The Foot Control provides an alternate means of controlling these same functions. The Wand is provided sterile and is single-use only.

RF20000a Controller

The RF20000a Controller is designed to deliver radiofrequency energy to the electrodes of the FLOW 50 Wand. The Controller is an enclosed unit with incorporated software that runs both the delivery of radiofrequency energy as well as a Graphical User Interface with which the user can control various modes, levels, volume, etc. Ports for connecting the FLOW 50 Wand and the Foot Control Pedal are located on the front panel.

The Controller incorporates a peristaltic integrated Fluid Outflow Regulator, which provides dynamic control of the rate of removal of conductive irrigating solution and/or fine, less dense, free-floating debris.

{6}------------------------------------------------

Intended Use/Indications for Use

There are no added procedures to the Indications for Use for the subject devices as compared to the predicate Ambient Super MultiVac Wand (K083306) and the Quantum 2 Controller (K082666). However, previously cleared procedures that utilized the Coagulation setting in order to thermally shrink tissue (e.g., Coagulation of Medial Retinaculum) were removed since the FLOW 50 Wand is not designed to be used in that manner. Removal of previously cleared procedures has no effect on the safety and effectiveness of the device when used as labeled.

The RF2000a Coblation System, comprised of the FLOW 50 Wand and the RF20000a Controller, is indicated for the resection, ablation, and coagulation of soft tissues and hemostasis of blood vessels in the following arthroscopic and orthopedic procedures:

Ablation/DebridementExcision/Resection

Substantial Equivalence

Non-clinical performance data such as design verification, software validation, tissue effect testing (histology, thermal margins), and peak temperature testing demonstrated that the subject devices are substantially equivalent to the predicate devices and are safe and effective when used as intended.

Summary

The RF20000a Coblation System is substantially equivalent to the predicate devices. The differences between the ArthroCare RF20000a Coblation System and the predicate devices do not raise any new concerns about the safety or effectiveness of the subject devices.
