Stedi Guidewire is intended for use to introduce and position catheters during interventional procedures within the chambers of the heart, including transcatheter aortic valve replacement (TAVR).

The Medtronic Stedi™ Extra Support Guidewire (herein after referred as Stedi Guidewire) is design for use to introduce and position catheters during interventional procedures within the chambers of the heart, including transcatheter aortic valve replacement (TAVR) procedures. The Stedi Guidewire has a 0.035" diameter and is 275cm in length and composed of two primary components: a core, and a coil. Both components are made of stainless steel. The core wire component is a piece of stainless-steel wire which is ground on the distal end to fit into the coil and provide flexibility. The coil and the ground core are joined in two locations: a proximal bond and a distal weld. The distal end of the Stedi Guidewire is comprised of a preformed 540° curved tip is available in 2 sizes (3cm and 4cm). The Stedi Guidewire has a polytetrafluoroethylene (PTFE) coating applied to the entire length of the device in order to aid in lubricity. The Stedi Guidewire is sterilized using ethylene oxide, nonpyrogenic, disposable, and for single use only.

The VitalFlow Console controls the speed of the VitalFlow Centrifugal blood pump during extracorporeal cardiopulmonary life support for adult patients with acute respiratory failure or acute cardiopulmonary failure, where other available treatment options have failed, and continued clinical deterioration is expected or the risk of death is imminent. The VitalFlow Centrifugal pump is driven by the VitalFlow Motor Drive or the VitalFlow Emergency Handcrank.

The VitalFlow Console provides control of blood pumping through an extracorporeal circuit during extracorporeal membrane oxygenation (ECMO) procedures. The console powers the VitalFlow motor drive unit which provides rotation of the VitalFlow Centrifugal pump. Pump motor speed (RPM) can be adjusted by the user and flow and bubble detection is provided by an ultrasonic flow probe and displayed on the touchscreen. The touchscreen display allows users to set alarm limits for all measured parameters. The device will alarm visually and audibly when limits are exceeded. Status indicators, power/battery life and secondary RPM indicator are provided. Data download and data streaming from the console is available for ECMO circuit data only; no patient data is stored for output.

Streamline temporary leads and wires treat an irregular heartbeat during or after cardiac surgery by providing electrical stimulation to the heart. - Models 6491, 6494, 6495, and 6500 are intended for atrial and ventricular use. - Model 6492 is intended for atrial use only. - Model 6491 and Model 6492 have smaller chest fixation coils and are appropriate for use in thin heart tissue and, in the case of Model 6491, a smaller chest cavity (for example, in a pediatric patient).

Each Streamline temporary pacing lead or wire comprises a lead body with a distal and a proximal segment. The distal segment has a separate electrode. A polypropylene monofilament (PP) fixation coil (except for model 6494) extends from the distal electrode end and is attached to a small, curved needle. The curved needle creates a channel in the myocardium for embedding the electrode. The PP fixation coil provides a means of securing the electrode in place. The proximal lead body terminates into a chest needle used to penetrate the chest wall, followed by pulling the proximal portion of the lead through the chest. The device is supplied sterile and intended for single use only.

The Cardioblate™ Gemini™ Surgical Ablation Device is intended to ablate cardiac tissue during cardiac surgery using radiofrequency energy. The system is indicated for use, under direct or endoscopic visualization, in surgical procedures, including minimally invasive surgical procedures.

The Cardioblate Gemini surgical ablation device (Model 49351), figure 1 below, is a handheld, single-use, bipolar, radio-frequency (RF) ablation device for use in cardiac surgery. It has a saline irrigation system to deliver fluid at the contact point between the tissue and electrode to cool the tissue during RF energy delivery. This device is intended for intermittent operation. Model 49260 of the Cardioblate Gemini surgical ablation device is intended for use with Cardioblate 68000 Generator (figure 2), whereas Model 49351 is intended for use with the Valleylab™ FT10 Energy(figure 3), whereas model 49260 is intended for use with Cardioblate 68000 Generator(figure 3). The devices are provided sterile and nonpyrogenic, are disposable, and are for single use only. They are sterilized using ethylene oxide. The Cardioblate Gemini-s is a bipolar electrode device that transmits radio frequency energy, generated by an external generator, between the two electrodes. The device has dual linear electrodes, 6.3 cm in length, with integral fluid delivery to the electrodes. The Gemini-s device is port accessible, intended for open or closed chest procedures to ablate tissue through resistive heating due to radiofrequency energy passing through tissue. The device is designed to reproduce the Cox-Maze lesion pattern by creating linear transmural lesions in both atria of the heart during cardiac procedures. The Gemini-s surgical ablation device has a flexible neck design that provides the physician with the ability to access various anatomies utilizing a neck curve through the full range from 0 to 180-degree configuration. Once the electrodes are correctly positioned, the parallel jaws lock by squeezing the handle. The electrodes have full contact with the tissue and the locking mechanism must be fully engaged to ensure accurate transmurality readings. Simultaneous with the actuation of the trigger and jaw closure is the opening of the (normally closed) fluid path to start the flow of saline. The device automatically shuts off the saline when the jaws are open and when the device is not in use.
