Baird MWA needle

Designed for microwave energy delivery

Explore the Baird microwave ablation (MWA) needle, including its design, ultrasound visualization, ex vivo ablation-zone data, and available configurations.

Ablation zone

Limited forward extension

Bench testing showed the ablation zone developing predominantly toward the shaft, with limited extension beyond the needle tip at tested settings.

Ex vivo porcine-liver bench testing, T-1408 needle; data on file. Volumes are shown in cm³ (1 cm³ = 1 mL).

Ablation dimensions vary with needle model, power, treatment time, and tissue conditions. Ex vivo results may differ from performance in perfused human tissue, and bench data are not predictive of clinical outcomes. Zone illustrations are representative geometry, not to scale.

Indications & Safety

Rx only. The Disposable Microwave Ablation Needle is indicated for coagulation (ablation) of soft tissue. Not intended for cardiac use. Sterile, single use only. Used with the Microwave Ablation System (BD-GT). Contraindicated in patients with massive bleeding tendency; not recommended for pregnant women; use caution in patients with severe coagulation dysfunction. Potential risks and complications include pain, bleeding or hematoma, swelling, thyroid-function changes, voice changes, and injury to nearby structures. Refer to the Safety Information and the Instructions for Use.
