Abstract
A probe that may be used to create circumferential lesions in body tissue and, in some implementations, may also be used to perform mapping functions. The probe includes a collapsible/expandable structure that supports electrodes or other operative elements against the body tissue.
Claims22
A mapping and coagulation apparatus, comprising:
- a tissue coagulation probe including
- a tissue coagulation probe support body defining at least one interior lumen,
- a hoop structure supported on the tissue coagulation probe support body, and
- at least one operative element supported on the hoop structure;
- and
- a mapping probe passable through the tissue coagulation probe support body lumen including
- a mapping probe support body, and
- an expandable/collapsible mapping basket supported on the mapping probe support body.

A mapping and coagulation apparatus, comprising:
- a tissue coagulation probe including
- a tissue coagulation probe support body defining at least one interior lumen,
- a hoop structure, including a hoop spline and at least first and second support splines, supported on the tissue coagulation probe support body, and
- at least one operative element supported on the hoop structure;
- and
- a mapping probe passable through the tissue coagulation probe support body lumen including
- a mapping probe support body, and
- a mapping structure supported on the mapping probe support body.
5 more elements
A probe, comprising:
- a support body defining a longitudinal axis;
- an expandable/collapsible hoop structure, including a hoop spline and at least first and second support splines, defining an open interior region and supported on the support body such that the longitudinal axis of the support body passes through the open interior region;
- and
- at least one operative element supported on the expandable/collapsible hoop structure.
1 more element
A probe, comprising:
- a support body defining a longitudinal axis and including a first support body member defining an inner lumen and a second support body member movable within the inner lumen;
- an expandable/collapsible hoop structure defining an open interior region and supported on the support body such that the longitudinal axis of the support body passes through the open interior region, the hoop structure including a first support spline operably connected to the first support body member and a second support spline operably connected to the second support body member and configured to collapse in response to movement of the first and second support splines in opposite directions;
- and
- at least one operative element supported on the expandable/collapsible hoop structure.
1 more element
A probe, comprising:
- a support body defining a longitudinal axis;
- an expandable/collapsible hoop structure defining an open interior region and supported on the support body such that the longitudinal axis of the support body passes through the open interior region and including a hoop spline and at least first and second distally extending support splines that respectively define acute angles with the longitudinal axis of the support body;
- and
- at least one operative element supported on the expandable/collapsible hoop structure.
