Abstract
A vascular plug includes a plurality of cells which extend from a front face of the plug towards a distal end of the plug. The cells form at least a periphery of the plug and are in the preferred embodiment closed at their distal ends. The cells may form a central chamber to the plug or may extend across the entirety of the front face of the plug. The cells will fill with blood from the patient's vessel, to inflate the plug and create a barrier to fluid flow. Static blood within the plug will clot over time, creating enhanced occlusion. The plug can also be configured as a vascular filter.
Claims19
A vascular plug having a proximal face and a distal end;
- the plug including a plurality of peripheral cells, each peripheral cell including a body element formed by at least one wall, wherein the wall is between adjacent cells, and each peripheral cell having a proximal end and tapering to a distal end such that each body element has a cross-sectional area which is narrower at the distal end than at the proximal end, each peripheral cell including an opening at its proximal end;
- the proximal ends of said peripheral cells being at or adjacent the proximal face of the plug such that the peripheral cells have shapes which tessellate around a periphery of the proximal face of the plug in an annular arrangement.
A vascular plug according to any preceding claim, wherein the cell openings form the proximal ends of the cells.
