Abstract: An embolus trap device is provided. The embolus trap device consists of an outer catheter, an inner catheter, a plurality of filter baskets, and a plurality of basket collapse wires. The filter baskets are of different radius and are positioned along the inner catheter in order of increasing radius from the proximal to the distal end. The filter baskets increase in radius so that any embolic fragment that flows past each basket has a chance to be caught and secured by a filter basket distal to it. The filter baskets are separately collapsible by the plurality of collapse wires and are collapsed in proximal-to-distal fashion with the largest basket being closed last in order to capture embolic fragments that may emerge from the smaller baskets because of disruptions as they are closed.

Abstract: A catheter assembly includes a catheter having an elongate tubular body defining a lumen extending from an open proximal end to an open distal end. A cuff deployment device is concentrically supported on the elongate tubular body and is movable along a longitudinal axis of the elongate tubular body. The cuff deployment device includes a deployment mechanism having an actuated position and a non-actuated position. A cuff has a hollow cylindrical body defining an internal catheter engagement surface. The catheter assembly has a first configuration in which the deployment mechanism is in the non-actuated position and the cuff is supported by and movable with the cuff deployment device, and a second configuration in which the deployment mechanism is in the actuated position and the cuff is concentrically mounted at a fixed axial location of the elongate tubular body and is free of contact with the cuff deployment device.
