How should metal implants and active medical devices be handled before HIFU?

A pacemaker, defibrillator, cochlear implant, surgical plate or screw, dental implant, wire, mesh or other metal cannot be managed with one universal HIFU rule. Exact type, location, manufacturer warning and proximity to the ultrasound path need verification before planning.

This translation has no recorded clinical or medical-language review.

Direct answer

Asking only whether metal is present is insufficient without its name, material and anatomical location.
Active electronic devices and passive metal components present different questions.
Current device labeling should be checked even when an implant seems remote from the proposed area.

Create an implant inventory

Use an implant card, operative note or imaging record to verify manufacturer, model, material, placement date and exact anatomical location. Electrical-safety questions for an active pacemaker or defibrillator differ from the position of a plate, screw, wire or dental implant in the energy path. Do not assume equivalence from a patient's recollection that an implant may be titanium.

Match the HIFU documentation

Read contraindications and warnings for the exact HIFU model, software and transducer. FDA guidance flags active and metal implants in the treatment area, while local labeling may be narrower or different. Do not copy a distance rule from another device. When information is unclear, written confirmation from the implanting clinician or manufacturer technical support may be appropriate.

No procedure is also a plan

Deferral is appropriate if the implant cannot be kept outside the energy path, its location is uncertain or the manufacturer gives no clear information. Simply shifting a template can create a different anatomical target. Compare the goal, expected limited change, alternatives and no treatment, and preserve the verified documents and chosen boundary in the patient record.
