Intended Use
The Diamondback 360 Peripheral Orbital Atherectomy System is a percutaneous orbital atherectomy system indicated for use as therapy in patients with occlusive atherosclerotic disease in peripheral arteries and who are acceptable candidates for percutaneous transluminal atherectomy. The OAS supports removal of stenotic material from artificial arteriovenous dialysis fistulae (AV shunt). The OAS is a percutaneous orbital atherectomy system indicated as a therapy in patients with occluded hemodialysis grafts who are acceptable candidates for percutaneous transluminal angioplasty.
Device Description
The Diamondback 360 Peripheral Orbital Atherectomy System (OAS) is intended for use in the treatment of peripheral arteries and A-V graft (shunt) stenosis. The OAS provides a method of removing stenotic material from peripheral arteries and A-V grafts. The Diamondback 360 uses an eccentrically rotating sarface (crown) to remove stenotic material on the vessel wall. The stenotic particles that are removed are small enough to be absorbed by the body. The Diamondback 360 Peripheral Orbital Atherectomy System consists of the following components: - 1) Orbital Atherectomy Device (OAD) - 2) Atherectomy Guide Wire (e.g., ViperWire Advance) - 3) Saline Infusion Pump (SIP) - 4) Atherectomy Lubricant (e.g., ViperSlide)
More Information

No
The device description and performance studies focus on mechanical and material properties, with no mention of AI/ML or related concepts like image processing, training data, or performance metrics typically associated with AI/ML algorithms.

Yes
The "Intended Use / Indications for Use" section explicitly states that the device is "indicated for use as therapy" in patients with occlusive atherosclerotic disease and for removing stenotic material from occluded hemodialysis grafts.

No
The device is described as a percutaneous orbital atherectomy system indicated for use as a therapy in patients with occlusive atherosclerotic disease and occluded hemodialysis grafts. Its function is to remove stenotic material, which is a therapeutic action, not a diagnostic one.

No

The device description explicitly lists multiple hardware components, including an Orbital Atherectomy Device, Guide Wire, Saline Infusion Pump, and Atherectomy Lubricant.

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

Here's why:

  • Intended Use: The intended use clearly describes a percutaneous orbital atherectomy system used within the body to treat occlusive atherosclerotic disease in peripheral arteries and artificial arteriovenous dialysis fistulae. This is an interventional procedure performed directly on the patient.
  • Device Description: The device components (Orbital Atherectomy Device, Guide Wire, Saline Infusion Pump, Lubricant) are all designed for use in a surgical or interventional setting, not for testing samples in vitro (outside the body).
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), reagents, or any other elements typically associated with in vitro diagnostic testing.

IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device is a therapeutic device used to physically remove blockages within blood vessels.

Description of Device

The Diamondback 360 Peripheral Orbital Atherectomy System (OAS) is intended for use in the treatment of peripheral arteries and A-V graft (shunt) stenosis.

The OAS provides a method of removing stenotic material from peripheral arteries and A-V grafts. The Diamondback 360 uses an eccentrically rotating sarface (crown) to remove stenotic material on the vessel wall. The stenotic particles that are removed are small enough to be absorbed by the body.

The Diamondback 360 Peripheral Orbital Atherectomy System consists of the following components:

    1. Orbital Atherectomy Device (OAD)
    1. Atherectomy Guide Wire (e.g., ViperWire Advance)
    1. Saline Infusion Pump (SIP)
    1. Atherectomy Lubricant (e.g., ViperSlide)

Description of Change

The 1.50 Solid Peripheral Orbital Atherectomy Device was modified to reduce the diameter of the shaft (drive shaft, drive shaft tip bushing, and saline sheath) including modification of the crown for compatibility with the smaller diameter drive shaft. In addition, the saline sheath material and design for the 1.50 Solid, 2.00 Solid, 1.50 Classic and 2.00 Classic OAD configurations were changed and an updated glue plug component was added to accomodate the new saline sheath design.

Intended Use

The Diamondback 360 Peripheral Orbital Atherectomy System is a percutaneous orbital atherectomy system indicated for use as therapy in patients with occlusive atherosclerotic disease in peripheral arteries and who are acceptable candidates for percutaneous transluminal atherectomy.

The OAS supports removal of stenotic material from artificial arteriovenous dialysis fistulae (AV shunt). The OAS is a percutaneous orbital atherectomy system indicated as a therapy in patients with occluded hemodialysis grafts who are acceptable candidates for percutaneous transluminal angioplasty.

Technology

The Diamondback 360 Peripheral Orbital Atherectomy System provides a method of removing or reducing occlusive atherosclerotic or stenotic material. The OAS applies a diamond coated, eccentrically rotating surface to remove stenotic material on the vessel wall. The stenotic particles that are removed are small enough to be absorbed by the body. This is the same technology that was cleared to market for use in the peripheral arteries for Stealth 360
