Abstract
A medical device includes an insertion tube, having a longitudinal axis and having a distal end adapted for insertion through a body passage into a cavity within a body of a patient. An electrode is located on the distal end of the insertion tube and is configured to contact tissue in the cavity. A resilient member is contained within the distal end of the insertion tube and is configured, when unconstrained, to cause the distal end to bend away from the longitudinal axis in a curved shape and to straighten toward the longitudinal axis when subjected to a force.
Claims7
Medical apparatus, comprising:
- a sheath, which has a longitudinal axis and a distal opening and is adapted for insertion through a body passage into a cavity within a body of a patient;
- and
- a catheter, which is configured for insertion through the sheath into the cavity and which has a resilient distal end that is formed so that, when unconstrained, the distal end bends away from the longitudinal axis in a curved shape, and when subjected to a force, the distal end straightens toward the longitudinal axis.
