    摘要： Devices and techniques for modifying and maintaining a configuration of an occlusion device for the closure of physical anomalies, such as an atrial septal defect, a patent foramen ovale (PFO), and other septal and vascular defects are described. The devices and techniques relate particularly to, but are not limited to, modifying and maintaining a configuration of a PFO occluder made from a polymer tube. The proximal portion of a catch member may be provided with one or more protrusions, or arms, or bump or other raised element for securing the occluder in a partial or fully deployed configuration, either temporarily or permanently.

    摘要： The invention generally relates to systems and methods for percutaneous closure of intra-cardiac openings, such as a patent foramen ovale (PFO). In one embodiment, a delivery system includes a first attachment mechanism and a second attachment mechanism attached to a closure device for implantation in an intra-cardiac opening. The delivery system can be used to deliver a closure device to the intra-cardiac opening, or to retrieve or re-position a closure device within the intra-cardiac opening.

    摘要： Devices, delivery systems and techniques for an occlusion device for the closure of physical anomalies, such as an atrial septal defect, a patent foramen ovale (PFO), and other septal and vascular defects are described. The devices, delivery systems and techniques relate to, but are not limited to, a patent foramen ovale (PFO) occluder made from a substantially cylindrical form. An occluder having a distal side and a proximal side, with a catch system for securing the deployed configuration, is introduced into the treatment site by a delivery sheath. In one aspect, the occluder has an adjustable length center joint that allows the device to fit a particular septal defect. In some embodiments, the occluder includes a catch member that holds the occluder in the deployed, expanded profile configuration. In one aspect, the catch member also has an adjustable length.

    摘要： The present invention provides systems and methods for occluding or closing a patent foramen ovale of a patient (PFO). The invention includes a catheter carrying an energy delivery element. The catheter introduces the energy delivery element into the patent foramen ovale of a patient's heart. Once appropriately positioned, the energy delivery element applies energy, such as radiofrequency energy, to the tissues surrounding the patent foramen ovale. The application of energy causes the tissues to join together, occluding the patent foramen ovale. The energy delivery element may be removable or permanently implanted in the patent foramen ovale.

    摘要： Sterilization devices and methods for deploying porous implants within the fallopian tubes are disclosed. The devices include a catheter component including an external electrode sheath containing at least two deployable implants and a positioning member. Sliding the external sheath proximally disposes the implants within the fallopian tubes, while sliding both the positioning member and external electrode sheath distally reloads a second implant into the external electrode sheath. The devices further includes a handle component, which houses a chassis, external electrode sheath carrier, reciprocating shaft, positioning member carrier and first and second engaging members. The reciprocating shaft may be operated by a motor to slide distally and proximally along a long axis. The reciprocating shaft, external electrode sheath and its carrier, upon selective actuation, move together proportionally to deploy and reload the implants to facilitate occlusion of the fallopian tubes and complete sterilization.

    摘要： A delivery catheter with a plug ejection mechanism with a fluid filled actuator incorporated in the catheter handle is disclosed. After delivery of RF energy, the plug is deployed within the region of the lesion by activating the plug ejection mechanism. A delivery catheter used for female sterilization with an atraumatic ball tip and an opening in the side wall of the catheter body is disclosed. The delivery catheter includes a hinge that will yield or bend under a certain load to prevent injury to the uterine wall or fallopian tube. The side wall opening is angled to allow proper placement of a plug into the fallopian tube for occlusion of the fallopian tube.

    摘要： Devices, delivery systems, and delivery techniques for an occlusion device for closure of physical anomalies, such as an atrial septal defect, a patent foramen ovale (PFO), and other septal and vascular defects are described. Specifically, an occluder with a catch member that holds the occluder in the deployed, expanded profile configuration is provided within a delivery sheath. The proximal end of the catch member includes a flap that when positioned proximal to the proximal end of the occluder holds the occluder in the expanded profile configuration. The flap is sized and formed of a material that allows the flap to deform by bending back and forth in axial and radial directions. In certain embodiments, the flap has segments divided by notches. In certain embodiments, deforming the flap in the proximal direction requires a different amount of force than deforming the flap in the distal direction.
