Abstract
Embodiments for a device, system and method for occluding an opening in a septum. Embodiments of the device can include a first control component, a first elongate member that extends from the first control component, a second elongate member, a connecting member that positions the first elongate member adjacent the second elongate member and a retraction member releasably coupled to the first control component. The retraction member can be used to change a relative position of the first elongate member and the second elongate member of the device.
Claims23
A clip, comprising:
- a first elongate member having a first elbow and a second elbow each with a lever arm that extends in an opposite direction to a pull member that both return to meet at a first control component;
- a retraction member that contacts and encircles the first control component to create a first releasable coupling, where a first retraction force applied to the first control component via the retraction member causes the lever arm to pivot at the first elbow and the second elbow as the pull member draws each lever arm toward the first control component and the retraction member separates from the first control component to release the clip;
- a second elongate member having a first pivot portion and a second pivot portion each with a lobe portion that extends in an opposite direction to meet at a second control component, where the retraction member contacts and encircles the second control component to create a second releasable coupling and a second retraction force applied to the second control component via the retraction member causes the pivot portions to swing past the lobe portion as the second control component moves towards the pivot portions and the retraction member separates from the second control component to release the clip;
- a first connection member that extends between the first elbow and the first pivot portion;
- and
- a second connection member that extends between the second elbow to the second pivot portion, where the first and second connection members position the first elongate member adjacent the second elongate member.
A system, comprising:
- an elongate catheter with a lumen extending between a proximal end and a distal end;
- a clip releasably housed in the lumen of the elongate catheter, where the clip includes:
- a first elongate member having a first elbow and a second elbow each with a lever arm that extends to a pull member that both meet at a first control component;
- a second elongate member having first pivot portion and a second pivot portion each with a lobe portion that meet at a second control component;
- a first connection member that extends between the first elbow and the first pivot portion;
- a second connection member that extends between the second elbow to the second pivot portion;
- a first filament that contacts and encircles the first control component to create a first releasable coupling, where the first filament can transmit a first retraction force to draw the first elongate member of the clip into the lumen of the elongate catheter and the first filament separates from the first control component to release the clip;
- and
- a second filament that contacts and encircles the second control component to create a second releasable coupling, where the second filament can transmit a second retraction force to draw the second elongate member of the clip into the lumen of the elongate catheter and the second filament separates from the second control component to release the clip.
