The "over the core wire" technique for detachable coil retrieval
1Department of Radiology, Kurume University School of Medicine; Asahimachi Kurume, Japan.
Summary:
We report four cases of malpositioned detachable coil retrieval. In all cases, the malpositioned coils were retrieved without additional neurological deficits. The stretched core wire was grasped with a fixed-loop snare (Gooseneck microsnare), and the detachable coil was retrieved using an over the core wire technique with a hydrophilic microcatheter.

Charging Conductors By Induction
Generally, conductors like metals do not allow any excess charge to be present on them. Any excess charge added to metals easily flows away, for example, when a metal is placed on the Earth. This process is called earthing.
However, conductors can be charged by a process called induction. For example, consider charging a...

Magnetic Force On Current-Carrying Wires: Example
Overcurrent Relays
Instantaneous overcurrent relays activate immediately when the input current exceeds a predetermined value, known as the pickup current, instantly energizing the circuit breaker trip coil. This rapid response is vital for addressing severe faults quickly.
Time-delay overcurrent relays, on the other...
