The Flexible Small Parts coil is comprised of a flexible coil winding, tune box, and clamp. The flexible coil winding is fabricated from a single strip of copper and encased in soft closed cell foam. The winding conforms to the irregular surface of anatomy and keeps the shape it is formed to while the foam provides consistent spacing between the windings and anatomy.

Decoupling is dual active and achieved with PIN diodes. The impedance of the coil is 50 ohms nominal and it is a solenoid type coil.

The Flexible Small Parts coil is constructed with the same materials that are currently in use for the released coil set for OPART™.

This request cannot be fulfilled. The document does not contain information about acceptance criteria and device performance for the K991740 submission. It describes a medical device accessory (Flexible Small Parts coil for OPART™ MRI system) and states its intended use, but it does not include performance metrics or a study. The document is primarily a 510(k) summary and the FDA's clearance letter, which focus on substantial equivalence to a predicate device rather than detailed performance studies against specific acceptance criteria.
