Intended Use

The Estech Cobra Surgical System is intended for the coagulation of cardiac tissue using radiofrequency (RF) energy during cardiac surgery. The System can be used during general surgery to coagulate soft tissues. The System may also be used to coagulate blood and soft tissue to produce hemostasis.

Device Story

Estech Cobra Surgical System comprises RF ablation probes (malleable or flexible shafts) and accessories (bipolar recording electrode); used with Cobra Electrosurgical Unit (ESU). Device inputs RF energy to coagulate cardiac/soft tissue; produces hemostasis. Used in open surgical fields by surgeons. XL version features up to 17 electrodes and stabilizers for placement; standard probe version lacks cooling water interface. Bipolar recording electrode facilitates sensing/pacing in open surgical fields. System benefits patients by enabling precise tissue coagulation during cardiac and general surgical procedures.

Clinical Evidence

Bench testing only. Preclinical performance data provided for the XL version to demonstrate it meets pertinent specifications. No performance data required for the Cobra Surgical Probe as it is identical to the predicate. Bipolar recording electrode performance verified via preclinical testing. Compliance with AAMI/ANSI HF-18 standard for electrosurgical devices certified.

Technological Characteristics

RF ablation probes with malleable or flexible shafts; bipolar recording electrode. Energy source: RF energy via Cobra ESU. Materials identical to predicate probes. Compliance with AAMI/ANSI HF-18. Non-implantable. Manual operation.

Indications for Use

Indicated for patients undergoing cardiac surgery requiring coagulation of cardiac tissue, and patients undergoing general surgery requiring coagulation of soft tissue or hemostasis.

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.

Predicate Devices

• Electrosurgical Probe (K981981)
• Cobra Adhere Surgical System (K041599)
