Abstract
Apparatus, having an insertion tube that is configured to be inserted into a body cavity. The apparatus also includes a distal tip connected to the insertion tube, the distal tip having an external surface and a cavity formed in the external surface, the cavity being surrounded by a region of the external surface having a curvature. The apparatus further includes a microelectrode configured to fit into the cavity so that a surface of the microelectrode is contoured, located and oriented to conform with the curvature of the region.
Claims18
A method, comprising:
- (a) providing an insertion tube that is configured to be inserted into a body cavity;
- (b) connecting a distal tip to the insertion tube, the distal tip configured with an external surface and a first cavity and a second cavity formed in the external surface, the first cavity being surrounded by a cylindrical region of the external surface configured with a first curvature, the second cavity being surrounded by a curved annular region of the external surface configured with a second curvature, the first cavity being defined by a first cavity side surface and a first base receiving surface, the second cavity being defined by a second cavity side surface and a second base receiving surface;
- and
- (c) fitting a first microelectrode into the first cavity and a second microelectrode into the second cavity so that:
- (i) a first base surface of the first microelectrode mates with the first base receiving surface in the cylindrical region of the distal tip and a first side surface of the first microelectrode simultaneously mates with the first cavity side surface of the distal tip, the first side surface configured with a generally uniform length,
- (ii) a first external surface of the first microelectrode is contoured, located and oriented to conform with the first curvature of the cylindrical region,
- (iii) a second base surface of the second microelectrode mates with the second base receiving surface in the annular region of the distal tip and a second side surface of the second microelectrode simultaneously mates with the second cavity side surface of the distal tip, the second side surface configured with a tapered length,
- (iv) a second external surface of the second microelectrode is contoured, located and oriented to conform with the second curvature of the annular region, and
- (v) wherein the first side surface of the first microelectrode includes a first grooved surface with a first configuration, and the second side surface of the second microelectrode includes a second grooved surface with a second configuration different from the first configuration.
