title: A newly designed directionally controlled guidewire.
abstract: A directionally controlled, 1:1 torque ratio flexible .035" guidewire has been developed for angioplasty procedures being done in the peripheral, renal, subclavian, and visceral circulation. A torque-controlling device is incorporated with the wire in order to negotiate the stenotic or ulcerative atherosclerotic site without damage to the intimal plaque. The increased selectivity of the wire has also found application in subselective examinations within the peripheral, visceral, and extracranial circulation. Four designed configurations are described.
