Abstract
The perivascular leak repair system, and method of using the same, of the present invention provides a sealant reservoir with a repair catheter operably attached; a flow control device disposed between the sealant reservoir and the repair catheter, and the flow control device responsive to a flow control signal; a heart phase detector generating a diastole phase signal; an injection switch generating a injection signal; and a flow controller responsive to the diastole phase signal and the injection signal, and generating the flow control signal. A method of sealing a perivascular leak comprises identifying the perivascular leak; inserting a repair catheter to the perivascular leak; injecting sealant at the perivascular leak; and removing the repair catheter. The sealant can be injected when the heart is in diastole to sweep the sealant into the perivascular leak.
