Abstract
Abstract An occlusion device (10,40) for percutaneous transluminal correction of intracardiac and vascular septal defects as disclosed. The device comprises a pair of opposed occluders (12,14,42,44) that are connected to one another using an interconnection (16,110) that allows the occluders to move relative to one another. Additionally, a means (150,156) for fluoroscopically visualizing and distinguishing the individual occluders of the device is also disclosed.

Claim 23
Independent Claim
237 words
A method for percutaneous transluminal repair of septal defects in a patient comprising the steps of: a) providing an occlusion device comprising a first occluder having an initial cross sectional configuration smaller than that of the defect to be repaired and a second expanded configuration larger than that of the defect, a second occluder having an initial cross sectional configuration and a second expanded configuration larger than that of the defect, and a connector for fastening the first occluder to the second occluder in a manner such that the first occluder may assume aligned and non-aligned attitudes with the second occluder; b) inserting the occlusion device with the first and second occluders in their initial configurations into a distal portion of a catheter sheath; c) transluminally guiding the distal portion of the catheter sheath to a first position on a first side of the defect; d) advancing the occlusion device relative to the sheath to release the first occluder and allow it to expand to its second configuration on said first side of the defect; e) moving said distal portion of the catheter sheath to a second position on a second side of the defect; f) retracting the catheter sheath to thereby release the second occluder and allow it to expand to its second configuration on said second side of the defect; and g) withdrawing the sheath while leaving the occlusion device in position across the defect.
