Methods, systems and devices for cardiac valve repair
First Claim
1. A method for treating regurgitation through a valve in a heart, the heart having an atrium fluidically coupled to a ventricle by the valve, the valve including at least two leaflets which coapt along a line of coaptation, the method comprising:
- introducing percutaneously a medical device system into a patient'"'"'s heart to a vicinity of a gap within the line of coaptation of the valve, the medical device system comprising;
a steerable guide catheter configured for delivery through the patient'"'"'s vasculature to the vicinity of the gap;
a retractable sheath moveably disposed over a device comprising a frame sized to fit within a heart chamber and a pair of arms moveably coupled to the frame, the arms are structurally configured to move from a fluid flow-blocking position during a systole to a fluid flow-allowing position during a diastole in response to pressure changes occurring between the systole and the dystole, the device being compressed to a reduced size by the retractable sheath when the retractable sheath is disposed over the device;
using the guide catheter to position the device within the gap along the line of coaptation;
retracting the sheath to release the blocker from compressive forces maintaining the device in the delivery configuration, the device expanding to a size larger than the reduce size in response to the sheath being retracted; and
retracting the catheter and the sheath from the heart.

Abstract
Disclosed are devices and methods for treating regurgitation through a valve in the heart. The devices can include an expandable, fluid-tight bladder configured to be deployed between valve leaflets of the heart valve. The bladder can include an upper portion that extends into the atrium of the heart; a lower portion that extends into the ventricle of the heart; and a middle portion positionable within the line of valve leaflet coaptation that provides a sealing surface for one or more of the leaflets.
