摘要: A closure device for a patent foramen ovale (PFO) has proximal and distal occlusion members for applying compressive forces to tissue on opposite sides of septal defects to help close the defects. The devices are collapsible for delivery and deployment, and can be easily retrieved and redeployed or repositioned if needed.

摘要: A delivery/recovery system to allow an operator to deploy and recover a medical implant, such as an occluder for closing a patent foramen ovale (PFO). In one embodiment, the system includes a delivery mandrel for preventing the occluder from moving in the proximal direction, a delivery wire for securing the occluder to the delivery mandrel and preventing unwanted movement in the distal direction, and a sheath for enveloping the delivery wire, mandrel and occluder. By moving the sheath relative to the occluder in a series of steps, the occluder opens first on a distal side and then on a proximal side, in a manner that holds the occluder in place.

摘要: A septal occluder, such as one made from a polymer tube, can have portions on either side of a patent foramen ovale (PFO) or other septal defect. The portions on either side can be held in place with a catching mechanism that can take one of many forms. The tube can be made of bioresorbable materials.

摘要: An occluder that has a coil on one or both sides of a medical defect, particularly a septal defect such as a patent foramen ovale (PFO). Each coil can be formed as a tube that is hollow, with or without a closed end. The tube can be delivered over a wire. For occluding a PFO, the coils can be designed to provide a compressive force to one or both of septum primum and septum secundum.

摘要: The invention generally relates to devices, systems, and methods for percutaneous closure of cardiac openings and obliteration of the cardiac cul-de-sacs. In one embodiment, a closure device includes a patch with an adhesive and/or a removable frame. The patch may be placed across a cardiac opening, such as a patent foramen ovale, or across a cardiac cul-de-sac, such as a left atrial appendage. In another embodiment, a closure device includes a balloon together with adhesives and/or substances for stimulating tissue growth coated on, or contained within, the balloon. The balloon may be inserted into a cardiac opening, such as the patent foramen ovale, or into a cardiac cul-de-sac, such as a left atrial appendage.
