The AtriCure Isolator Synergy EnCapture Clamp is intended to ablate cardiac tissue during surgery.

The AtriCure Isolator Synergy EnCapture Clamp (referred to hereafter as CLAMP) is a single patient use electrosurgical instrument designed for use with an AtriCure RF GENERATOR. The CLAMP is used for cardiac tissue ablation. When activated, the GENERATOR delivers radiofrequency (RF) energy to the linear electrodes on the insulated jaws of the device. The Operator controls the application of this RF energy by pressing the Footswitch. The CLAMP features two pairs of opposing dual electrodes, an in-line handle with syringe-type actuation and button release mechanism. The device outer and ablative faces of the distal jaw segments have textured surfaces to increase the engagement between the jaw face and the cardiac tissue. The CLAMP is compatible with the Gidepath Tape Instrument (hereafter known as GUIDE), that is designed to attach to the fixed jaw of the CLAMP with a half turn attachment end connection. The GUIDE is a single-patient, optional component designed to facilitate the guidance of the CLAMP around target tissue during general surgical procedures.

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

The CLAMP is a single-use electrosurgical instrument offered in two configurations: standard length jaws (OSH), and long length jaws (OLH). All Isolator devices are configured as vascular clamps and feature clamping jaws of various lengths and curvatures. The AtriCure Isolator clamps feature an in-line handle with syringe-type actuation and button release mechanisms. The GUIDE is a single-use surgical accessory designed to facilitate the guidance of surgical instruments through tissue during cardiothoracic surgical procedures. The GUIDE has a flexible, malleable shaft, and magnetic attachment ends that connect to the metal tip of the CLAMP jaws inside the jaw magnet cups.

For Adult Patients AtriCure's Cryo2 cryo2 cryoablation probes are sterile, single use devices intended for use in the cryosurgical treatment of cardiac arrhythmias by freezing target tissues, creating an inflammatory response (cryonecrosis) that blocks the electrical conduction pathway. The Cryo2 cryolCE cryo-ablation probes are also intended for use to temporarily block pain by ablating peripheral nerves. For Adolescent Patients The Cryo2 cryolCE cryo-ablation probes are intended for use to temporarily block pain by ablating intercostal nerves under direct visualization1 in adolescent patients of at least 12 years of age. 1 Direct visualization, in this context, requires that the surgeon is able to see the targeted tissue for cryoablation directly or with assistance from a camera, endoscope or other similar optical technology. For Adult Patients AtriCure's cryolCE cryoSPHERE cryoablation probes are sterile, single use devices intended for use performed by freezing target tissues, creating an inflammatory response (cryonecrosis) for blocking pain by temporarily ablating peripheral nerves. For Adolescent Patients The cryolCE cryoSPHERE cryo-ablation probes are intended for use to temporarily block pain by ablating intercostal nerves under direct visualization1 in adolescent patients of at least 12 years of age. 1 Direct visualization, in this context, requires that the surgeon is able to see the targeted tissue for cryoablation directly or with assistance from a camera, endoscope or other similar optical technology.

The cryosurgical handpiece, or cryo-ablation probe, utilized in the AtriCure Cryosurgical System is a hand held, single use, cryosurgical instrument intended for the cryosurgical treatment of cardiac surgery; it is also intended for use in blocking pain by temporarily ablatinq peripheral nerves. The cryosurgical handpiece uilizes a high-pressure cryogen (nitrous oxide, N20) to freeze target tissues, creating an inflammatory response, and ultimately, cryonerosis. The cryosurgical handpiece provides below -40°C, the temperature at which intracellular ice formation occurs which is considered lethal to cells. When high pressure nitous oxide is supplied to the cryprobe via the AtriCure Cryo Module, rapid cooling is achieved via the Joule-Thompson effect. The end effector, or cryolip, of the probe is malleable to allow access to varying anatomy and anatomical sites. The cryo-ablation probes are comprised of a cryotip end effector, shaft, handle, thermocouple, inlet tube, and exhaust tube. The cryotip consists of an aluminum boiler and three infices distributed throughout the cryotip internally to provide uniform cooling. The 4-mm diameter, cryotip is malleable throughout its 10-cm length. A supplied forming tool can be cryotip into the desired form. The cryolip is attached to an insulated rigid shaft that allows the surgeon to adjust the exposed cryolip up to 10 cm in therapeutic length. A thermocouple is affixed to the proximal external surface of the temperatures on the console. The handle is attached to the shaft. Inlet and exhaust tubes and thermocouple wire pass through the handle and connect to the AtriCure Cryo Module (ACM). The cryoICE PROBE is a sterile, single-use cryosurgical instrument. The form tool facilitates bending of the malleable tip. This PROBE was designed for treatment of cardieving controlled temperatures down to -50° to -70°C; it can also be used to temporarily block pain by ablating peripheral nerves in adolescent patients of at least 12 years of aqe. The cryolCE cryoSPHERE cryoablation (CRYOS/CRYOS-L) probe is a single use cryablation of peripheral nerves by allowing a surgeon to insert the probe through an incision to reach the probe tip on the target site, and in conjunction with an AtriCure Cryo Module (ACM), temporarily freeze the tissue in by circulating a cryogenic agent, nitrous oxide, through the device. The CRYOS probe is offered in two probe length configurations: approximately 11" and 18" long. The probe is malleable and is capable of being bent by the end user. At the distal end, the CRYOS device features an 8 mm diameter ball tip shaped probe. The PROBE is a single-use device offered in two configurations: standard length probe shaft (CRYOS), and extended length probe shaft (CRYOS-L). The probe shaft is malleable and supports forming by the supplied TOOL. The PROBE features a spherical 8mm cryoablation tip.

The AtriClip LAA Exclusion System is indicated for the occlusion of the heart's left atrial appendage, performed under direct visualization and in conjunction with other cardiac surgical procedures. Direct visualization, in this context, requires that the surgeon is able to see the heart directly, with or without assistance from a camera, endoscope, etc., or other appropriate viewing technologies.

The AtriClip LAA Exclusion System consists of a single use, sterile, self-closing, implantable Clip preloaded on a Single Use Clip Applier along with a selection guide. When closed, the Clip applies uniform pressure over the length of the Clip to ensure consistent, reproducible, and secure occlusion of the left atrial appendage (LAA). The clip is then deployed and is left as a permanent implant. The Clip is available in the following lengths to accommodate different sizes of LAA: 35 mm, 40 mm, 45 mm, and 50 mm. The Clip Appliers are disposable devices with a handle, shaft, suture anchors, and deployment end-effector containing the Clip.

The Isolator linear pen is a sterile, single use electro surgery device intended to ablate cardiac tissue during cardiac surgery using radiofrequency (RF) energy when connected directly to the ASU or ASB in Ablation mode. The Isolator linear pen may be used for temporary cardiac pacing, sensing, recording, and stimulation during the evaluation of cardiac arrhythmias during surgery when connected to a temporary external cardiac pacemaker or recording device.

The Isolator™ linear pen System is comprised of the AtriCure® Ablation and Sensing Unit (ASU), Isolator™ linear pen (Pen), Footswitch, ASU Source Switch(ASB). The Pen is a single patient use electrosurgical instrument designed for use only with the ASU and ASB. The Pen is used to ablate cardiac tissues and as a surgical pacing and mapping tool. When the Pen is connected to the ASU, the ASU provides the bipolar radiofrequency (RF) energy flowing between both electrodes of the Pen. The Operator controls the application of this RF energy by pressing the Footswitch. When the Pen is connected to an auxiliary pace, sense, or stimulation device; the Pen is designed to provide temporary pacing or monitoring.
