ATRIAL SEPTAL CLOSURE DEVICE FOR RE-ACCESS

摘要

In particular embodiments, a septal orifice closure device for closing a septal defect can include a frame structure comprising a coil having a first loop turn, a second loop turn and a third loop turn. A biodegradable member can be attached to the second loop turn, for example. The second loop turn can be sandwiched between the first and second loop turns. The biodegradable member can be replaced by the body with scar tissue formation and endothelial cells such that only the frame member remains in the body after a period of time. The lumen can be configured to allow a medical device to be inserted through the device at the location of the previous orifice at a later time as other therapeutic interventions are warranted.

1. A septal orifice closure device comprising:
a helical frame comprising at least two turns and defining a central lumen; and at least one biodegradable member attached to the frame and configured to block the flow of blood through the lumen and between the left and right atriums when the frame is deployed within a septal orifice in a septum of a heart of a patient.
