Intended Use

The Medtronic M2 Adjustment Tool is a magnetic tool that is used to non-invasively adjust the Strata-type Valve when a stronger magnet is warranted by the surgeon. The Medtronic M2 Adjustment Tool is used in conjunction with Strata® handtools.

Device Story

The Medtronic M2 Adjustment Tool is a handheld magnetic device used by surgeons to non-invasively adjust the operating pressure of implanted Strata-type valves. By placing the tool in close proximity to the valve, the magnetic field moves the internal rotor, allowing for performance level changes without invasive revision surgery. The device is used in conjunction with Strata handtools in a clinical setting. It provides a benefit to patients by enabling necessary valve adjustments while avoiding the risks associated with surgical intervention.

Clinical Evidence

No clinical data provided; substantial equivalence is based on technological characteristics and intended use compared to predicate devices.

Technological Characteristics

Magnetic adjustment tool; handheld form factor; operates via magnetic field interaction with internal valve rotor; used in conjunction with Strata handtools. No software or electronic components.

Indications for Use

Indicated for non-invasive adjustment of Strata-type valves in patients requiring pressure/flow characteristic changes, when a stronger magnet is warranted by the surgeon.

Regulatory Classification

Identification

A central nervous system fluid shunt is a device or combination of devices used to divert fluid from the brain or other part of the central nervous system to an internal delivery site or an external receptacle for the purpose of relieving elevated intracranial pressure or fluid volume (e.g., due to hydrocephalus). Components of a central nervous system shunt include catheters, valved catheters, valves, connectors, and other accessory components intended to facilitate use of the shunt or evaluation of a patient with a shunt.

Predicate Devices

• Adjustment tools for Medtronic PS Medical® Strata® Valve and Shunt Assemblies (K012052, K033850, and K042465)

Description: The Medtronic M2 Adjustment Tool is a magnetic tool that is used to non-invasively adjust the Strata-type Valve when a stronger magnet is warranted by the surgeon. External adjustment of the valve prevents the need for an invasive revision procedure. To adjust the operating pressure of the valve, the adjustment tool is used in close proximity to the valve to move the rotor within the valve.

Intended Use: The Medtronic M2 Adjustment Tool is a magnetic tool that is used to non-invasively adjust the Strata-type Valve when a stronger magnet is warranted by the surgeon. The Medtronic M2 Adjustment Tool is used in conjunction with Strata® handtools.

Intended Use of predicate device(s): The adjustment tools for the PS Medical Strata Valve and shunt component are used to non-invasively change the performance level (pressure/flow characteristics) of the Strata type valve.
