Atrial Septal Occluder Device and Method
First Claim
1. A steerable atrial septal occluder device for repairing an atrial septal defect in a human heart, said device comprising:
- an elongated catheter having a distal end adapted to be inserted into and moved along a blood vessel and into a heart of a patient;
a proximal end adapted to remain outside of a patient'"'"'s body and said catheter including a head portion, a tail portion and a neck portion between said head portion and said tail portion and said neck portion including a plurality of series connected segments disposed between said head portion and said main or tail portion;
an atrial septal occluder removeably fixed to said head portion and means for positioning said atrial septal occluder with respect to an atrial septal defect activatable from said proximal end to bend said neck portion;
means including a control mechanism for closing an atrial septal occluder over an atrial septal defect from said proximal end; and
means for separating said atrial septal occluder from said head portion of said catheter from said proximal end of said catheter.

Abstract
An atrial septal occluder device for repairing an atrial septal defect in a human heart includes an elongated catheter for insertion into and moved along a blood vessel and into the heart of a patient. The catheter includes a head portion, a tail portion and a neck portion between the head and tail portions. The neck portion is about 1 cm in length and 2 to 4 mm in diameter. The device also includes an Amplatzer ASO removably fixed to the head of the device and a moveable neck portion for positioning the ASO with respect to the ASD and an activator for closing the ASO over the ASD from outside of the patient'"'"'s body.

15. A steerable atrial septal occluder device for repairing an atrial septal defect in a human heart consisting of in combination:
-
an elongated catheter having a distal end adapted to be inserted into and moved along a blood vessel and into a heart of a patient; a proximal end adapted to remain outside of a patient'"'"'s body and said catheter including a head portion, a tail portion and a neck portion between said head portion and said tail portion and said neck portion of said catheter including a plurality of axially aligned stainless steel discs having a diameter of about 2 mm and a central opening forming three overlapping passageways through said plurality of discs and defining three overlapping circular cross sections and a plurality of stainless steel coil springs between said disc and a universal joint consisting of two cross bars with one of said bars in an upwardly extending member on each side of said spring; an atrial septal occluder removably fixed to said head portion and means including a control member and two activators operatively connected to said head portion for positioning said atrial septal occluder with respect to an atrial septral defect actuated from said proximal end of said catheter to thereby bend said neck portion, and said means for positioning said atrial septal occluder with respect to an atrial septal defect further including central springs and two central cables for bending said neck portion of said catheter and wherein said springs and said cable extend from said head portion to said proximal end of said catheter through said central opening in said disc; means including said control member for closing said atrial septal occluder over an atrial septal defect from said proximal end of said catheter; and means including said control member for separating said atrial septal occluder from said head portion of said catheter. - View Dependent Claims (16)
