| 20080221609 | Vein filter - A vessel filter comprising a first region and a second region wherein the filter is movable between a collapsed position for delivery to the vessel and an expanded position for placement within the vessel. A first region has a filter portion having a converging region to direct particles toward the center of the filter and the second region is flared in the expanded position to have a transverse dimension increasing toward a second end portion opposite the first end portion. The second region includes a vessel engaging portion at the second end portion. The first region includes a plurality of spaced apart elongated struts with adjacent struts being joined and a spacer extending radially with respect to a longitudinal axis of the filter. | 09-11-2008 |
| 20080302368 | Fallopian tube occlusion device - A device for occluding the fallopian tube comprising a retention member and a mesh material supported by the retention member. The retention member has a first lower profile configuration for delivery and a second expanded configuration for placement within the fallopian tube. The mesh material is configured to block passage of an egg through the tube. The member has a plurality of tube engagement members to secure the retention member to the fallopian tube. | 12-11-2008 |
| 20090099596 | Closure device for left atrial appendage - A device for closing the left atrial appendage of a patient comprising a retention member composed of a shape memory material and a mesh material supported by the retention member. The retention member has a first elongated configuration for delivery and a second expanded configuration for placement within the left atrial appendage. The mesh is configured to block blot clot migration from the appendage. In the second configuration the retention member moves toward a shape memory position. The retention member has a plurality of appendage wall engagement members to secure the retention member to the appendage. | 04-16-2009 |
| 20090143813 | Method of inserting a vein filter - A method of implanting a vessel filter by a femoral approach comprising the steps of providing a delivery sheath with a substantially straight distal tip and inserting a curved device into the sheath to move the sheath to a second configuration. In the second position, the distal tip of the sheath is curved at an angle to a longitudinal axis of the sheath. The method further comprises the step of rotating the sheath and pusher so a distal opening of the sheath has a more centered position within the vessel. | 06-04-2009 |
| 20100063535 | METHOD OF REMOVING A VEIN FILTER - A method of removing an implanted vessel filter by a femoral approach comprising the steps of providing a catheter with a curved tip, inserting a straightening device into the catheter to move the catheter tip from a curved position to a more straightened position, advancing the catheter tip through the femoral vein and past a cranial end of the filter, withdrawing the straightening device to enable the catheter tip to return to the curved condition, and inserting a filter grasping device though the catheter and a curved catheter tip to exit a distal portion to grasp the filter. | 03-11-2010 |
| 20110040314 | Rotational Thrombectomy Wire With Blocking Device - A thrombectomy apparatus for breaking up thrombus or other obstructive material in a lumen of a vascular graft or vessel. The apparatus includes a wire having a first configuration and a second deployed configuration, the wire having a straighter configuration in the first configuration. The wire is operatively connected to a motor for rotation of the wire to contact and break up the thrombus or other obstructive material. A blocking device at a distal portion of the apparatus is movable between a collapsed configuration and an expanded configuration, and is configured in the expanded configuration to block thrombus dislodged by rotation of the wire. | 02-17-2011 |
| 20110208233 | DEVICE FOR PREVENTING CLOT MIGRATION FROM LEFT ATRIAL APPENDAGE - A device for placement within the left atrial appendage of a patient comprising a retention member and a material positioned within the retention member and unattached thereto. The retention member has a first elongated configuration for delivery and a second expanded configuration for placement within the left atrial appendage. The material is configured to float within the retention member. The retention member can have at least one appendage wall engagement member to secure the retention member to the appendage. | 08-25-2011 |
| 20110259341 | Fallopian Tube Occlusion Device - A device for occluding the fallopian tube including a retention member and a mesh material supported by the retention member. The retention member has a first lower profile configuration for delivery and a second expanded configuration for placement within the fallopian tube. The mesh material is configured to block passage of an egg through the tube. The member has a plurality of tube engagement members to secure the retention member to the fallopian tube. | 10-27-2011 |
