Quantitatively mapping metals in tissue by laser ablation - inductively coupled plasma - mass spectrometry (LA-ICP-MS) is a sensitive analytical technique that can provide new insight into how metals participate in normal function and disease processes. Here, we describe a protocol for quantitatively imaging metals in thin sections of mouse neurological tissue.

Pulmonary vein isolation (PVI) with an ablation catheter is a curative treatment for atrial fibrillation (AF). Robotic catheter systems aim to improve catheter steerability. Here, a procedure with a new robotic catheter system is presented. The goal of the procedure is electrical block between pulmonary vein and left atrium.
FAQs
The treatment effect depends on how plasma energy is delivered to the tissue. Controlled changes in plasma generation, exposure time, and energy level can favor tissue removal through vaporization or tissue modification through coagulation. The device and the characteristics of the selected tissue target also influence which response is produced, allowing clinicians to match the effect to the intended procedure.
Energetic particles and reactive species interact with biological tissue at the molecular level. Their activity disrupts molecular bonds, which changes the structure of the exposed tissue and can lead to removal or coagulation. Because these effects occur where the plasma is applied, controlling the treatment field helps concentrate molecular disruption at the intended site.
Energy delivery and exposure time regulate how strongly and how long tissue encounters the plasma. Precise control helps determine the extent of molecular disruption and whether the result is tissue removal, modification, or coagulation. These variables are therefore central to localized treatment, particularly when clinicians aim to limit effects on nearby biological structures.
A treatment begins with selecting the appropriate device and identifying the tissue target. The clinician then generates plasma through an electrical field and applies it to the selected site while controlling energy delivery and exposure time. The resulting tissue response, such as removal or coagulation, reflects how those conditions were matched to the intended clinical objective.
Plasma ablation can support several types of medical treatment, including surgical tissue removal, dermatologic procedures, and management of selected lesions. Its use depends on the device and the tissue being treated. This range reflects the technique’s ability to produce different localized effects, from removing tissue to modifying or coagulating a targeted area.
Localized treatment allows clinicians to direct plasma energy toward a defined tissue site rather than broadly affecting surrounding structures. By controlling plasma generation, exposure time, and energy delivery, the method can concentrate its effects where treatment is needed. This principle is relevant across surgical, dermatologic, and lesion-management settings, although the suitable application depends on the device and target tissue.
