Device Description
Khelix Diagnostic Electrophysiology Catheters are a range of electrophysiology diagnostic cardiac catheters designed to facilitate electrophysiological mapping of the heart. The devices are intended for the electrical recording and/or stimulation of endocardial structures. The device consists of a catheter handle and catheter shaft containing an array of platinum-iridium electrodes for stimulation and recording. The subject device comes in a variety of models based on the distal catheter configuration including Steerable and Loop models. The device interfaces with standard electrophysiological recording equipment, such as ECG monitoring equipment, impedance based navigational equipment and cardiac stimulation equipment, via the Khelix Diagnostic Extension Cable (supplied separately). The device is available in different device models with several variants according to electrode configurations, curve types and loop diameters, as applicable. The subject catheters use 4 to 20 electrodes with variable spacing to provide for variation in physician preference. The catheter is intended to be used with the Khelix Diagnostic Extension Cable. The extension cable connects distally to the catheter (sterile field) and proximally to standard electrophysiology (EP) laboratory equipment such as heart signal monitors/records and stimulators (non-sterile field) via shielded tip pins. The Khelix Diagnostic Electrophysiology Catheter range is supplied sterile. The devices are sterilized using an ethylene oxide (EtO) sterilization process.
More Information

Not Found

No
The summary describes a standard electrophysiology catheter for recording electrical signals. There is no mention of AI or ML in the device description, intended use, or performance studies. The device interfaces with standard EP equipment, suggesting it is a data acquisition tool, not an analytical one using AI/ML.

No
The device is indicated for electrical recording and stimulation, which are diagnostic and mapping functions, not therapeutic interventions.

Yes

The device's intended use and device description explicitly state that it is for "electrical recording" of endocardial structures and "electrophysiological mapping of the heart," which are processes to identify and understand heart rhythms or other conditions. The name itself, "Khelix Diagnostic Electrophysiology Catheters," also indicates a diagnostic purpose.

No

The device description clearly states it consists of a catheter handle and shaft with electrodes, which are physical hardware components. It is not solely software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is for the "electrical recording of endocardial structures" and "obtaining and recording electrograms from the atrial region of the heart." This describes a procedure performed on the patient's body to measure electrical signals directly from the heart tissue.
  • Device Description: The device is a catheter designed for "electrophysiological mapping of the heart" and "electrical recording and/or stimulation of endocardial structures." It interfaces with standard electrophysiological recording equipment. This is consistent with a device used for an in-vivo procedure.
  • Lack of In Vitro Activity: There is no mention of the device being used to test samples (like blood, urine, tissue) outside of the body. IVD devices are specifically designed to examine specimens taken from the human body.

In summary, the Khelix Diagnostic Electrophysiology Catheters are used for a diagnostic procedure performed directly on the patient's heart, not for testing samples in a laboratory setting. This aligns with the definition of an in-vivo diagnostic device, not an in-vitro diagnostic device.

Device Description

Khelix Diagnostic Electrophysiology Catheters are a range of electrophysiology diagnostic cardiac catheters designed to facilitate electrophysiological mapping of the heart. The devices are intended for the electrical recording and/or stimulation of endocardial structures.

The Khelix Diagnostic Electrophysiology Catheter range is used by cardiologists in electrophysiology (EP) studies to determine the cause of an abnormal heart rhythm, to locate the site of origin of an abnormal heart rhythm, to decide the best treatment for an abnormal heart rhythm, and/or to check the effectiveness of ablation therapy. An EP study is sometimes conducted before placement of an implantable cardioverter/defibrillator (ICD) to determine the best type of device, and to monitor treatment effectiveness.

The device consists of a catheter handle and catheter shaft containing an array of platinum-iridium electrodes for stimulation and recording. The subject device comes in a variety of models based on the distal catheter configuration including Steerable and Loop models. The device interfaces with standard electrophysiological recording equipment, such as ECG monitoring equipment, impedance based navigational equipment and cardiac stimulation equipment, via the Khelix Diagnostic Extension Cable (supplied separately). The device is available in different device models with several variants according to electrode configurations, curve types and loop diameters, as applicable. A full list of model variants is detailed at the end of this summary.

The subject catheters use 4 to 20 electrodes with variable spacing to provide for variation in physician preference.

The catheter is intended to be used with the Khelix Diagnostic Extension Cable. The extension cable connects distally to the catheter (sterile field) and proximally to standard electrophysiology (EP) laboratory equipment such as heart signal monitors/records and stimulators (non-sterile field) via shielded tip pins.

The Khelix Diagnostic Electrophysiology Catheter range is supplied sterile. The devices are sterilized using an ethylene oxide (EtO) sterilization process.

An EP study is sometimes conducted before placement of an implantable cardioverter/defibrillator (ICD) to determine the best type of device, and to monitor treatment effectiveness.

The device consists of a catheter handle and catheter shaft containing an array of platinum-iridium electrodes for stimulation and recording. The subject device comes in a variety of models based on the distal catheter configuration including Steerable and Loop models.
