Medtronic Lead Anchor Accessory Model 3550-01
Not Found
No
The device description and performance studies focus on the mechanical properties and function of a physical anchor for spinal cord stimulation leads, with no mention of AI or ML.
No.
The Medtronic Twist Lock Anchor is described as an accessory or anchor for use with Spinal Cord Stimulation (SCS) systems, which are therapeutic devices, but the anchor itself does not directly provide a therapeutic effect. It facilitates the function of the SCS system.
No
Explanation: The device is an anchor accessory for spinal cord stimulation systems used in the treatment of chronic pain. It is an implantable device used to secure leads, not to diagnose a condition.
No
The device description explicitly states it is an "implantable device" made of physical materials (polysulfone and stainless steel) and is used to anchor a lead, indicating it is a hardware component.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Description and Intended Use: The Medtronic Twist Lock Anchor is an implantable device used as an accessory for Spinal Cord Stimulation (SCS) systems. It is physically implanted in the body to secure a lead for pain management.
- Lack of Biological Sample Testing: The description does not mention the device being used to test any biological samples from the patient. Its function is purely mechanical, providing an anchor point for the SCS lead.
Therefore, the Medtronic Twist Lock Anchor falls under the category of an implantable medical device, not an in vitro diagnostic device.

Device Description
The Medtronic Twist Lock Anchor is an implantable device. It is used with Spinal Cord Stimulation (SCS) systems for the treatment of chronic intractable pain of the trunk or limbs.
The anchor is assembled from three parts: the driver and the shell which are made of polysulfone, and a stainless steel pin which is press fitted into the shell. The compression created by the fit of the driver within the shell grips the lead body outer jacket.
The Medtronic Twist Lock Anchor can be used only with coiled conductor Medtronic Neurological Spinal Cord Stimulation leads that require anchor sleeve and that have an outside diameter of 1.27 mm.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Medtronic, Inc. has provided descriptive data on the test plan and test results for the Twist Lock Anchor. These data support that the function and characteristics of the device are suitable for its intended use.
Flex testing was performed which demonstrated that the lead body, while gripped by the anchor, has equivalent flex characteristics as the lead body gripped by the current silicone anchor.
Pull testing was performed that demonstrated the breakaway load of the Twist Lock Anchor is equivalent to the current silicone rubber anchor.

§ 882.5880 Implanted spinal cord stimulator for pain relief.
(a)
Identification. An implanted spinal cord stimulator for pain relief is a device that is used to stimulate electrically a patient's spinal cord to relieve severe intractable pain. The stimulator consists of an implanted receiver with electrodes that are placed on the patient's spinal cord and an external transmitter for transmitting the stimulating pulses across the patient's skin to the implanted receiver.(b)
