OCCLUDER WITH ACCESS PASSAGE AND CLOSURE THEREOF
The present disclosure is directed to embodiments of an occlusive medical device including a frame and at least one closure coupled to the frame. The frame includes a distal annular flange having a radially outer surface and a radially inner surface, a proximal annular flange having a radially outer surface and a radially inner surface, and a waist portion extending between and connecting the distal annular flange to the proximal annular flange. The radially inner surface of the distal annular flange, the waist member, and the radially inner surface of the proximal annular flange define an unobstructed passageway through the frame. The at least one closure is configured to close the passageway to: (i) provide an occlusive effect, and (ii) enable subsequent access through the passageway.
Sealing device and delivery system
The invention relates to a sealing device for repair of cardiac and vascular defects or tissue opening such as a patent foramen ovale (PFO) or shunt in the heart, the vascular system, etc. and particularly provides an occluder device and trans-catheter occluder delivery system. The sealing device would have improved conformity to heart anatomy and be easily deployed, repositioned, and retrieved at the opening site.
Projecting member with barb for cardiovascular devices
A medical implant including an expandable framework configured to shift between a collapsed configuration and an expanded configuration, the expandable framework comprising a plurality of interconnected struts defining a plurality of cells; and an occlusive element connected to the expandable framework and having an inner surface and an outer surface. The expandable framework may include a plurality of securement members projecting from the plurality of interconnected struts. One of the inner surface or the outer surface of the occlusive element may be in contact with the plurality of interconnected struts, and the other of the inner surface and the outer surface not in contact with the plurality of interconnected struts may lie against an opposing surface of each of the plurality of securement members. A tip portion of the plurality of securement members may not extend radially outward of the plurality of interconnected struts.
Insertable catheter device for patch application
An insertable catheter device includes a shaft including a proximal end and a distal end, an expandable balloon, and an actuator configured to expand and retract the expandable balloon. The actuator includes a fluid conduit that extends through the shaft and is coupled with the expandable balloon to enable inflation and retraction of the expandable balloon via injection or withdrawal of a fluid to or from the expandable balloon via the fluid conduit. The expandable balloon is displaceably retractable into the shaft and extendable from the shaft. A fluid pump is coupled with the fluid conduit to pump the fluid through the fluid conduit. A patch is positioned to be displaced by the expandable balloon when the expandable balloon is inflated, and the expandable balloon is displaceably retractable into the shaft and displaceably extendable from the shaft.

System and method for laparoscopic repair of abdominal wall hernia using umbrella mesh
The system and method for laparoscopic repair of abdominal wall hernia using umbrella mesh includes an umbrella mesh having a substantially circular mesh attached to an umbrella-like frame having a plurality of radially spaced spokes resiliently mounted at a hub, the spokes being hollow and housing helical tacks. The umbrella mesh is folded and mounted on an umbrella load cartridge. The cartridge may be loaded on the distal end of a pistol-grip laparoscopic instrument having a rotary control for orienting the mesh over the weakened area, a mesh release handle for gradually opening and releasing the mesh, and a firing handle for firing helical tacks from the spokes for fastening the mesh to the supporting abdominal wall.
Occluder and Occlusion System
The present application provides an occluder, for use in occluding a defect in a vascular system. The occluder comprises a first occlusion disc, a second occlusion disc, and a tightening wire; the first occlusion disc and the second occlusion disc are used for covering different openings of a defect, respectively; a connector is provided on the first occlusion disc; the connector is provided with a wire passing hole; the tightening wire passes through the wire passing hole of the connector; two ends of the tightening wire pass through the second occlusion disc, and form an adjustment wire knot on the side of the second occlusion disc facing away from the first occlusion disc; the distance between the first occlusion disc and the second occlusion disc can be adjusted by the ends of the tightening wire. The present application also provides an occlusion system having the occluder.
DOUBLE SIDED OCCLUSIVE DEVICE
This application discloses an occlusive device that includes a frame movable between a deliver condition and a blocking condition, the frame including a center region, a plurality of distal arms, a plurality of proximal arms, where both the distal and proximal arms curve away from the center region, with flexible sheet material couple to both the distal and proximal arms that block a lumen when the frame is in the blocking condition. Also disclosed is a method of manufacturing the occlusive device and a medical device incorporating the occlusive device.
Self-closing devices and methods for making and using them
A self-closing device for implantation within a patient's body includes base material including an inner surface area for securing the base material to a tissue structure, and a plurality of support elements surrounding or embedded in the base material. The support elements are separable laterally within a plane of the base material to accommodate creating an opening through the base material for receiving one or more instruments through the base material, and biased to return laterally towards a relaxed state for self-closing the opening after removing the one or more instruments. The device may be provided as a patch or integrally attached to a tubular graft or in various shapes.
