Cauterizing needles are disclosed that include a needle having a hollow, electrically conductive needle shaft, and an insulating sheath disposed on the conductive needle shaft. Also disclosed are methods for using the cauterizing needle, one method including passing a cauterizing needle through a vascular tissue, insulating the tissue from the cauterizing shaft of the needle, cauterizing the tissue solely via the tip of the needle shaft, and either withdrawing a substance via a syringe attached to the needle or dispensing a substrate via a syringe attached to the needle. With the apparatus and/or method, specific tissues and/or vessels can be selectively cauterized while using a syringe attached to the cauterizing needle. |
