Abstract
An electrophysiology catheter with a distal microelectrode assembly having covered spine carrying a plurality of microelectrodes. The microelectrode assembly includes a first spine radiating away from the longitudinal axis, the first spine having a plurality of first microelectrodes disposed on the first spine and a second spine adjacent the first spine and radiating away from the longitudinal axis. The second spine has a plurality of second microelectrodes disposed on the second spine such that a first virtual circle intersecting one of the plurality of first microelectrodes do not intersect any of the second microelectrodes.
Claims24
A medical probe comprising:
- an elongated member extending along a longitudinal axis;
- a distal electrode assembly coupled to the elongated member, the electrode assembly comprising:
- a proximal stem extending along the longitudinal axis;
- a first spine radiating away from the longitudinal axis, the first spine having a plurality of first microelectrodes disposed on the first spine;
- a second spine adjacent the first spine and radiating away from the longitudinal axis, the second spine having a plurality of second microelectrodes disposed on the second spine such that a first virtual circle intersecting one of the plurality of first microelectrodes do not intersect any of the second microelectrodes.
An electrophysiology medical probe comprising:
- a distal electrode assembly comprising:
- a proximal stem defining a longitudinal axis;
- a plurality of spines extending along the longitudinal axis;
- a plurality of first microelectrodes disposed on a first spine;
- a plurality of second microelectrodes disposed on a second spine adjacent the first spine;
- in which the plurality of first microelectrodes is spaced along the first spine so that the first microelectrodes are offset with respect to the second microelectrodes by a stagger distance as measured along the longitudinal axis.
An electrophysiology medical probe comprising:
- a distal electrode assembly comprising:
- a plurality of spines, each spine defining a longitudinal axis;
- a plurality of first microelectrodes disposed on a first spine, each of the first microelectrodes having its centerline disposed at an eccentric distance relative to the longitudinal axis of the first spine in a first direction generally transverse to the longitudinal axis;
- and
- a plurality of second microelectrodes disposed on a second spine adjacent the first spine, each of the second microelectrodes having its centerline disposed at an eccentric distance relative to the longitudinal axis in a second direction away from the first direction.
