Intended Use

The Stellartech Radiofrequency Generator is indicated for use in general surgical procedures to coagulate soft tissues. The Stellartech Radiofrequency Generator may also be used to coagulate blood and soft tissues to produce hemostasis.

Device Story

The Stellartech Radiofrequency Generator (Models 1025A-115/230) is an electrosurgical unit supplying up to 25 watts of unipolar radiofrequency energy to electrodes in contact with tissue. The device continuously monitors and displays delivered power, tissue impedance, and duration of power application. User controls allow setting of power levels and maximum duration. Safety mechanisms include automatic shutdowns for overvoltage, overcurrent, and overpower conditions. Used in general surgical settings by clinicians to coagulate soft tissue and blood for hemostasis, as well as to cut soft tissue. The device provides controlled energy delivery to facilitate surgical procedures.

Clinical Evidence

Bench testing only. No clinical data provided. Compliance with electrical safety and electromagnetic compatibility standards (EN 60601 series) was used to demonstrate substantial equivalence.

Technological Characteristics

Electrosurgical generator; unipolar output up to 25W; monitors power, impedance, and time. Complies with EN 60601-1 (General Safety), EN 60601-1-1 (Systems), EN 60601-1-2 (EMC), EN 60601-1-4 (Programmable Electrical Medical Devices), and EN 60601-2-2 (High Frequency Surgical Equipment).

Indications for Use

Indicated for use in general surgical procedures to cut and coagulate soft tissue in patients requiring such surgical intervention.

Regulatory Classification

Identification

An electrosurgical cutting and coagulation device and accessories is a device intended to remove tissue and control bleeding by use of high-frequency electrical current.
