20090275976 | EMBOLIC FILTERING METHOD AND APPARATUS - The present invention relates generally to a device and method for preventing the undesired passage of emboli from a venous blood pool to an arterial blood pool. The invention relates especially to a device and method for treating certain cardiac defects, especially patent foramen ovales and other septal defects, through the use of an embolic filtering device capable of instantaneously deterring the passage of emboli from the moment of implantation. The device consists of a frame, and a braided mesh of sufficient dimensions to prevent passage of emboli through the mesh. The device is preferably composed of shape memory allow, such as nitinol, which conforms to the shape and dimension of the defect to be treated. | 11-05-2009 |
20100076545 | MEDICAL DEVICE ANCHOR AND DELIVERY SYSTEM - A method and apparatus for anchoring a medical implant device after the device has been brought to rest at a desired position within a blood vessel or other body passageway. An anchor delivery system is provided which houses one or more uniquely configured expandable anchors which are connected to the medical implant device. The anchors remain housed in a non expanded configuration until after the medical implant device has come to rest in a desired position within the body, and then the anchors are positively propelled through a body wall from a first side to a second side where each anchor expands outwardly from an anchor shaft. In one configuration, the anchors are each formed in the shape of a compressible closed loop which extends outwardly from an anchor shaft and loops back to cross over and extend beyond the anchor shaft. To positively propel the anchors, a drive shaft for the anchor shafts extends back to a triggering unit which, when activated, causes the drive shaft to drive the anchor shafts in a direction which results in propulsion of the anchors through the body wall. | 03-25-2010 |

20110106237 | ALTERNATING CIRCUMFERENTIAL BRIDGE STENT DESIGN AND METHODS FOR USE THEREOF - A stent includes a first section and a second section. The first section and the second section each include a plurality of expandable modules and a plurality of bridging modules. Each expandable module includes a plurality of strut elements that join together at a plurality of apices, and each bridging module includes bridging elements that connect an apex of a first module with an apex of a second module. In some aspects, the first section is more flexible along the longitudinal axis of the stent than the second section and is configured to be placed in a specific region of a vessel that requires flexibility to accommodate surrounding anatomy. In some aspects, the first section is more radially stiff than the second section and is configured to be placed in a specific region of the vessel that requires radial stiffness to counteract crushing force caused by surrounding anatomy. | 05-05-2011 |
20110230957 | ALTERNATING CIRCUMFERENTIAL BRIDGE STENT DESIGN AND METHODS FOR USE THEREOF - A stent includes a first section and a second section. The second section is aligned with the first section along a longitudinal axis of the stent. Each section includes a plurality of expandable modules and a plurality of bridging modules. Each expandable module includes a plurality of strut elements that join together at a plurality of apices. Each bridging module includes bridging elements that connect an apex of a first module with an apex of a second module. The plurality of expandable modules or the plurality of bridging modules in the first section are more radially stiff than the plurality of expandable modules or the plurality of bridging modules in the second section such that at least a portion of the first section is configured to be placed in a region of a vein subjected to physiologic compression. | 09-22-2011 |
20130103026 | TISSUE TREATMENT DEVICE AND RELATED METHODS - A hypotube based deliver system is used to position one or more elements in position for treatment within the body. The elements may include electrodes, sensors or injection ports or even anchors. The hypotubes may have pre-set shapes or are plastically deformed prior to positioning as they exit a positioning device. There are methods of providing therapy using the hypotubes including mixed mode therapies are also described. | 04-25-2013 |
20130218195 | MEDICAL DEVICE ANCHOR AND DELIVERY SYSTEM - A method and an apparatus for anchoring a medical implant device within a blood vessel or other body passageway are described herein. An anchor delivery system houses one or more expandable anchors connected to the medical implant device. The anchors remain housed in a non-expanded configuration until the medical implant device has been placed in a desired position within the body, and then the anchors are propelled through a body wall where each anchor expands outwardly from an anchor shaft. In one configuration, each anchor is formed as a compressible closed loop which extends outwardly from an anchor shaft and loops back to cross over and extend beyond the anchor shaft. To propel the anchors, a drive shaft is connected to a triggering unit which, when activated, causes the drive shaft to drive the anchor shafts in a direction such that the anchors are propelled through the body wall. | 08-22-2013 |

20120184985 | Removeable Embolus Blood Clot Filter and Filter Delivery Unit - A blood clot filter is collapsible toward a longitudinal axis into a collapsed configuration for insertion into a blood vessel, and is radially expandable outwardly from the longitudinal axis to an expanded configuration for contact with the inner wall of the blood vessel at two longitudinal spaced locations. A first plurality of spaced, elongate arms, in the expanded configuration, curve outwardly away from the longitudinal axis toward the leading end of the filter to form a first filter basket and to center a hub at the trailing end of the filter within the vessel. A second plurality of spaced elongate legs angle outwardly away from the longitudinal axis toward the leading edge of the filter in the expanded configuration to form a second filter basket opening toward the leading end. The ends of these legs include hooks to bend and straighten in response to withdrawal force. | 07-19-2012 |
20140081316 | Removable Embolus Blood Clot Filter and Filter Delivery Unit - A blood filter includes a hub, a plurality of legs, and a plurality of arms. Each of the legs includes a hook at a distal end thereof, a first linear segment extending substantially parallel to a hub longitudinal axis, a second linear segment extending obliquely with respect to the longitudinal axis at a first angle, and an intermediate linear segment coupled to the first and second segments, the intermediate segment extending obliquely with respect to the longitudinal axis at a second angle less than the first angle. Each of the arms has a free end closer to the longitudinal axis than the hook of each of the legs. The free ends of the arms are spaced radially transverse to the longitudinal axis at substantially the same radial distance. | 03-20-2014 |
