Abstract
The present invention relates to a needle-like probe (1) for use in electrical potential sensing and RF ablation of tissue, a method of making such probes (1), and a probe array comprising a number of such probes (1). The probe (1) has an elongated body (2, 22) with one end (9,29) adapted for penetration of tissue. The body (2, 22) has sufficient rigidity to be inserted into the tissue. The elongated body (2, 22) also comprises two or more electrodes (7, 27) separated and spaced apart from each other along the elongated body (2, 22) by insulative material (8, 28). Each electrode (7, 27) has at least one electrical conductor (10, 11) coupled to the electrode (7, 27). The electrode (7, 27) is capable of delivering RF energy to the tissue surrounding the electrode (7, 27) and sensing the electrical potential of the tissue. Preferably, the two or more electrodes (7, 27) each comprises a metal band incorporated in the elongated body (2, 22) and optionally include a thermal sensing means for measuring the temperature at the interface between the electrode (7, 27) and the tissue. Still further, the elongated body (2, 22) can internally incorporate an elongated rigid member (14) for provid…
