Delivery system for patent foramen ovale closure device
First Claim
1. A medical device comprising:
- a tether shaft configured to be removably coupled to a closure device;
at least one filament configured to be connected to an atrial anchor of the closure device, said at least one filament configured to facilitate movement of the atrial anchor of the closure device; and
a filament operating shaft configured to be selectively linked to said tether shaft, wherein said at least one filament is connected to said filament operating shaft.

Abstract
A medical system for use in reducing the size of an internal tissue opening is disclosed. The medical system can include a patent foramen ovale or PFO closure device and a delivery device therefore. The PFO closure device can include left and right anchors connected by a stem. The delivery device is configured to selectively deploy at least one of the right or left anchors of PFO closure device so as to enable a practitioner to adjust PFO closure device during the positioning procedure. In one embodiment, the delivery device includes a filament operating shaft linked to the right anchor by one or more filaments. A practitioner can move the filament operating shaft to selectively deploy and retract the right anchor during positioning of the PFO closure device. Furthermore, the delivery device comprises a tether shaft for coupling delivery device to PFO closure device. In one embodiment, the tether shaft comprises a first portion and a flexible second portion, wherein the flexible second portion is at a distal end of the tether shaft.
