There is disclosed a porous emboli deflector for preventing cerebral emboli while maintaining cerebral blood flow during an endovascular or open surgical procedure. The device prevents the entrance of emboli of a size able to cause stroke (such as greater than 100 microns) from entering either the right or left common carotid arteries, and/or the right or left vertebral arteries by deflecting emboli downstream of these vessels. The device can be placed prior to any manipulation of the heart or aorta allowing maximal protection of the brain during the index procedure. The deflector has a low profile within the aorta which allows sheaths, catheters, or wires used in the index procedure to pass. Also disclosed are methods for insertion and removal of the deflector.

A surgical portal assembly includes a portal member adapted for positioning within a tissue tract and defining a longitudinal axis with leading and trailing ends. The portal member includes at least one longitudinal port for passage of an object. The portal member comprises a compressible material adapted to transition between a first expanded condition to facilitate securing of the portal within the tissue tract and in substantial sealed relation with tissue surfaces defining the tissue tract, and a second compressed condition to facilitate at least partial insertion of the portal within the tissue tract. The portal assembly also includes an elongated member extending through the at least one longitudinal port and mechanically couplable to the portal member adjacent the leading end thereof. The elongated member is adapted to move through the at least one longitudinal port in a trailing direction to exert a compressive force at least adjacent the leading end to cause the portal member to transition toward the compressed condition.

The deflector shaft could have a first portion and a second portion, the second portion being more flexible than the first portion. The deflector frame can include one, two, or more movable structures, such as hinges. Also disclosed are methods for insertion and removal of the deflector.
