A surgical shunt (1) has a tubular body (2) with internal bore (3). A port (9) is provided intermediate the ends (4, 5) of the body (2) for delivery of a medical device such as a collapsible embolic protection filter (16) carried by a guidewire (17). The filter (16) is deployed downstream of the shunt (1) to entrap embolic material released during a surgical procedure. The length of the external proximal portion of a mounting system is greater than the sum of the length of the entry port (9) and a distal section of the shunt bore (3). The shunt can be completely removed while maintaining the filter (16) in place to protect against embolic material released during shunt removal. |
