Intended Use

Caiman Seal and Cut Technology consists of dedicated bipolar electrosurgical instruments intended for use in general surgery and gynecologic surgical procedures where ligation of vessels is desired. The instruments create a seal by the application of bipolar electrosurgical RF energy (coagulation) to vascular structure (vessels) interposed between the jaws of the device. A cutting blade is actuated for the division of tissue. Instruments 24 cm in length are indicated for open procedures and instruments 36 cm and 44 cm in length are indicated for laparascopic procedures. The include general surgical procedures, (including urologic, vascular, thoracic, and thoracoscopic), and gynecological procedures where ligation of vessels is performed. These procedures include: vaginal hysterectomies, Nissen fundoplication, colectomy, adhesiolysis, bowel resection, and oophorectomy etc., or any procedure where vessel ligation (seal and cut), tissue grasping, and dissection is performed. The devices can be used on vessels up to and including 7mm and bundles as large as will fit in the jaws of the instrument. Caiman Seal and Cut Technology has not been shown to be effective for tubal sterilization or tubal coagulation for sterilization procedures. Do not use the system for these procedures.

Device Story

Caiman Seal and Cut Technology comprises bipolar electrosurgical instruments used with the Lektrafuse RF Generator. Device inputs: vascular tissue placed between instrument jaws. Operation: bipolar RF energy applied to seal vessels; integrated mechanical cutting blade divides tissue. Used in open (24 cm) and laparoscopic (36 cm, 44 cm) procedures by surgeons. Output: sealed and divided tissue. Benefits: efficient vessel ligation and tissue dissection. System includes 5mm articulating instruments, shaft gaskets, and specific cable connectors. Healthcare providers use the device to perform procedures like hysterectomies, colectomies, and bowel resections.

Clinical Evidence

Bench testing only. Testing included articulation angle/torque, biocompatibility, cutter advancement, blade termination, dissection distance, jaw gap, flow rate, force to lock/release, instrument life, jaw adhesion, jaw force, tissue resistance, sealing performance (length, size, time), seal burst pressure on three tissue types, thermal spread, trocar compatibility, and visual arcing.

Technological Characteristics

Bipolar electrosurgical instrument; RF energy source via Lektrafuse generator. Materials include unspecified dissection clip and heat shrink. Complies with IEC 60601-2-2, IEC 60601-1-2, IEC 60601-1 (3rd Ed), and IEC 60601-2-18. Sterile, single-use. Features include 5mm articulating jaw, shaft gasket, and distal cable connector.

Indications for Use

Indicated for patients undergoing general, urologic, vascular, thoracic, thoracoscopic, and gynecological surgical procedures requiring vessel ligation, tissue grasping, and dissection. Compatible with vessels up to 7mm. Contraindicated for tubal sterilization or tubal coagulation procedures.

## SUBSTANTIAL EQUIVALENCE

Caiman Seal and Cut Technology is substantially equivalent to the Caiman Seal and Cut Technology system cleared via K130596.

# DEVICE DESCRIPTION

Caiman Seal and Cut Technology consists of the Lektrafuse RF Generator and the Caiman seal and cut devices which are provided as sterile, single use devices. These devices are capable of vessel sealing, blunt dissection, grasping and dividing tissue enclosed within its jaws during open and laparoscopic procedures. The devices are designed to be used with the dedicated Lektrafuse RF Generator and create vessel ligation by the application of bipolar electrical RF energy and tissue division with a cutting blade. The 5 mm instruments (not the generator) are the subject of this submission.

The devices can be used on vessels up to and including 7mm and bundles as large as will fit in the jaws of the instrument.

Caiman Seal and Cut Technology has not been shown to be effective for tubal sterilization or tubal coagulation for sterilization procedures. Do not use the system for these procedures.

# TECHNOLOGICAL CHARACTERISTICS (compared to predicates)

The modifications made to the Caiman Seal and Cut Technology system do not affect the fundamental scientific technology. The principal of operation has not changed for these devices. The following modifications made to these devices do not raise any new issues of safety and effectiveness: addition of 5mm articulating instrument, addition of a gasket in the shaft, shaft length, isolator assembly, distal cable connector, an adhesive change. Material changes were made to the dissection clip and heat shrink material.

## PERFORMANCE DATA

Bench testing was performed on the modified devices and found them to be substantially equivalent to the predicate devices. The testing included the following tests: Articulation Angle/Torque, Biocompatibility, Cutter Advancement, Cutting Blade Termination, Dissection Distance, Distal Jaw Gap, Flow Rate, Force to Lock and Release Jaw, Instrument Life, Jaw Adhesion, Jaw Force (clamping compression), Jaw Grasp, Tissue Resistance Test, Sealing (length, size & time), Seal Burst Pressure on three different tissue types, Thermal Spread Trocar Compatibility, Visual Arcing and Regrasp.

The Caiman Seal and Cut Technology is in compliance with the following safety standards: IEC 60601-2-2, IEC 60601-1-2, IEC 60601-1: 3" Edition, and IEC 60601-2-18.
