FLATTENED MESH ABLATION DEVICE

摘要

A flattened mesh ablation device for ablating tissue in a body lumen is disclosed. The flattened mesh ablation device includes a flattened mesh with at least one conductor on an edge of the flattened mesh. When the flattened mesh is compressed axially it expands radially to contact the inner surface of the body lumen in a helical pattern. Energy is applied to the conductor ablating tissue proximate the conductor.

主权项

1. A medical device comprising:
a first longitudinal member having a distal end and a proximal end; a flattened mesh having a distal mesh end and a proximal mesh end, the flattened mesh being twisted to form a helix, the proximal mesh end being secured to the distal end of the first longitudinal member; a conductor on an edge of the helix; and a compression mechanism adapted to move the distal mesh end between a first position in which the flattened mesh is unexpanded and a second position in which the distal mesh end and the proximal mesh end are near one another thereby expanding the flattened mesh into an expanded state.
