Collapsible medical device for atrial sealing and trans-septal access

Abstract

The present disclosure provides collapsible medical devices that may be introduced via a delivery device into a pre-existing patent foramen ovale or trans-septal puncture hole and left in place to provide both a sealing function on the atrial wall and a septal-access function for additional procedures. The disclosed medical devices include a penetrable and re-sealable gasket material disposed in an open lumen in the medical device. This penetrable and re-sealable material allows catheters or other medical devices to pass therethough for providing additional therapy to an individual. By allowing the access point or portal to be opened by a guidewire or another medical tool, the medical devices as disclosed herein may be particularly suitable for a variety of cardiac procedures including, for example, atrial fibrillation, mitral valve replacement or repair, left atrial appendage closures, and the like.
