US Patent 11771411 PFO device

A medical device for treating a PFO is presented as well as a mechanism for its delivery, repositioning and/or removal. The device includes a wire or cable framework of six shape-memory cables formed into a right side having six loops that support a right side sail and a left side having six loops that support a left side sail. The right side loops and left side loops are connected together via waist members that extend between the right side and left side loops. Each cable is threaded through a through hole of a central post and pass through one of each of four types of connecting collars that establish the basic shape of the PFO device and retain the cables together to form a flexible and resilient PFO device.
