Tilted crisscross spiral grooves reflect ultrasound waves back to the transducer, making needle placement easier to visualize.

Periodic in vivo balloon inflation and deflation preserves tissue spacing during radiotherapy while relieving continuous compression of healthy tissue.

Controlled cooling of retrolingual and retropalatal fat reduces airway obstruction in sleep apnea while limiting bleeding and damage to nearby tissue.

Continuous local anaesthetic delivery near anal nerves extends pain relief after hemorrhoidectomy and helps reduce opioid use.

A foot-controlled syringe pump lets one clinician inject or aspirate while limiting pressure to reduce nerve damage risk.

Indirect analgesia signals and PK-PD models guide closed-loop hypnotic and analgesic dosing to maintain anesthesia and avoid awareness or overdosing.

Porous absorbable tubes deliver medicines directly to wounds or body cavities, enabling localized treatment without repeated invasive administration.
