Patent ID: 7200445

Claim:
A catheter for use with a power supply, the catheter comprising: an elongate sheath having a near end, a far end adapted for insertion into the body, and having a flexibility to accommodate navigation through tortuous anatomy, the sheath having a passageway extending therethrough, a flexible elongate shaft slidably located within the passageway and having an outer shaft surface; an energy transfer basket coupled to the shaft, the energy transfer basket comprising a plurality of legs adapted to apply energy to a body lumen, each leg having a distal end and a proximal end, each leg having a flexure length that is less than a full length of the leg; a near alignment component having a plurality of near seats extending along an axis of the alignment component, the near alignment component secured to the elongate shaft; a far alignment component having a plurality of far seats extending along an axis of the alignment component, where the plurality of near seats are in alignment with the plurality of far seats; a connector for coupling the energy transfer basket to a power supply; and where each distal end of each leg is nested within a far seat of the far alignment component and each proximal end of each leg is nested within a near seat of the near alignment component such that an angle between adjacent legs is determined by an angle between adjacent near seats and the flexure length of each length is determined by the distance between near and far alignment components.
