Perivascular leak repair system

摘要

The perivascular leak repair system, and method of using the same, of the present invention provides a sealant reservoir 102 with a repair catheter 104 operably attached; a flow control device 106 disposed between the sealant reservoir 102 and the repair catheter 104, and the flow control device 106 responsive to a flow control signal 108; a heart phase detector 114 generating a diastole phase signal 112; an injection switch 122 generating a injection signal 120; and a flow controller 110 responsive to the diastole phase signal 112 and the injection signal 120, and generating the flow control signal 108. A method of sealing a perivascular leak comprises identifying the perivascular leak 140; inserting a repair catheter to the perivascular leak 142; injecting sealant at the perivascular leak 144; and removing the repair catheter 146. The sealant can be injected when the heart is in diastole to sweep the sealant into the perivascular leak.
