Intended Use

The AtriCure Isolator Synergy EnCompass Clamp and Guide system is intended to ablate cardiac tissue during surgery.

Device Story

The Isolator Synergy EnCompass Clamp and Guide system is a single-use electrosurgical instrument used by surgeons in cardiothoracic procedures to ablate cardiac tissue. The system consists of a vascular clamp (available in standard OSH or long OLH jaw configurations) and a malleable magnetic guide (GPM100). The clamp features an in-line handle with syringe-type actuation and button release. The guide facilitates instrument positioning through tissue via magnetic attachment to the clamp's metal jaw tips. The device operates by delivering bipolar radiofrequency (RF) energy from an AtriCure Ablation and Sensing Unit (ASU2) to linear electrodes on the clamp jaws. The surgeon controls energy delivery via a footswitch. By creating controlled lesions in cardiac tissue, the device assists in surgical ablation procedures, potentially benefiting patients by treating cardiac arrhythmias.

Clinical Evidence

No human clinical data provided. Substantial equivalence supported by non-clinical bench testing, including mechanical, ex vivo ablation comparison, reliability, external surface temperature, electrical safety, shelf life, and biocompatibility testing, alongside a GLP animal study.

Technological Characteristics

Bipolar RF electrosurgical clamp; single-use; PETG blister/Tyvek packaging; Ethylene Oxide sterilized (SAL 10^-6). Materials are biocompatible per ISO 10993. Features in-line handle, syringe-type actuation, and magnetic guide attachment. Operates with ASU2 generator.

Indications for Use

Indicated for ablation of cardiac tissue during surgery. No specific patient population, age, or gender restrictions are provided.

Regulatory Classification

Identification
