    摘要: The present invention provides an occluder for a biological defect, such as an atrial septal defect (ASD) or a patent foramen ovale (PFO). The occluder is at least partially formed of a radiopaque, bioabsorbable material. In some embodiments, the occluder is formed from a tube, which is cut to produce struts in each side. Upon the application of force, the struts deform into loops. The radiopaque, bioabsorbable material is a blend of a biocompatible radiopaque material with a bioabsorbable material. In some embodiments, the radiopaque material may have a mass attenuation coefficient greater than about 1.2 cm2/gm and/or a linear attenuation coefficient greater than about 9 cm−1. In some embodiments, the radiopaque material is tungsten. In some embodiments, the bioabsorbable material may have a molecular weight greater than about 300,000. In some embodiments, the bioabsorbable material is a polymer.

    摘要: An apparatus for cutting a suture. In one embodiment the suture cutting apparatus includes a distal cutting end and a proximal control end. The apparatus also includes a first tube defining a lumen, and a second tube located and movable within the lumen of the first tube. The second tube defines a lumen and includes a lever arm pivotably attached at the distal cutting end of the apparatus. The lever arm has a cutting edge that is held away from the longitudinal axis of the second tube when the lever arm is located within the first tube, and is biased toward the longitudinal axis of second tube when the lever arm is outside of the first tube.

    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.

The devices, delivery systems and delivery techniques relate particularly to, but are not limited to, a patent foramen ovale (PFO) occluder made from a polymer tube. In certain embodiments, the occluder includes a catch system that holds the occluder in the deployed, expanded profile. The catch system includes a locking funnel cap. In some embodiments, the locking funnel cap forces the proximal ends of the occluder in a radially inward position to lock the catch member in place and prevent the occluder from moving from its deployed configuration.

    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.
