Abstract: An intravascular catheter for nerve activity ablation and/or sensing includes one or more needles advanced through supported guide tubes (needle guiding elements) which expand to contact the interior surface of the wall of the renal artery or other vessel of a human body allowing the needles to be advanced though the vessel wall into the extra-luminal tissue including the media, adventitia and periadvential space. The catheter also includes structures which provide radial and lateral support to the guide tubes so that the guide tubes open uniformly and maintain their position against the interior surface of the vessel wall as the sharpened needles are advanced to penetrate into the vessel wall. Electrodes near the distal ends of the needles allow sensing of nerve activity before and after attempted renal denervation. In a combination embodiment ablative energy or fluid is delivered from the needles in or near the adventitia to ablate nerves outside of the media while sparing nerves within the media.

Abstract: A wearable garment and an arrangement of electrodes configured to measure bioelectrical signals from a patient. The dry electrodes are free from adhesives to hold the electrodes in place on the patient's skin. The arrangement of the electrodes may be configured to limit noise and facilitate accurate signal sensing from the patient even with some amount of relative movement between the electrodes and the patient's skin. The wearable garment may be controllable to change the amount of compression based on the sensed signals from the electrodes, and from other sensors. The garment may maintain a comfortable level of compression until processing circuitry detects a signal of interest, such as a cardiac arrhythmia, irregular respiration, or some other signal. The processing circuitry may cause the wearable garment to increase compression to improve the contact between the electrodes and the patient's skin and improve reception of the measured signals.

Abstract: A catheter for use in a patient's heart, especially for mapping a tubular region of the heart, has a catheter body, a deflectable intermediate section and a distal a mapping assembly that has a generally circular portion adapted to sit on or in a tubular region of the heart. A control handle of the catheter allows for single-handed manipulation of various control mechanisms that can deflect the intermediate section and contract the mapping assembly by means of a deflection control assembly and a linear control assembly. The deflection control assembly has a deflection arm and a rocker member. The linear control assembly has a linear control member, an inner rotational member and a cam. A pair of puller members are responsive to the deflection control assembly to bi-directionally deflect the intermediate section. A third puller member is responsive to the linear control assembly to contract the generally circular portion of the mapping assembly.
