Claims22
1-20. (canceled)
A device comprising:
- a first tube having a proximal end for manipulation during a surgical procedure, a distal end for insertion into a surgical site, a hollow core, and an exit from the hollow core at the distal end;
- one or more flaps coupled to the distal end of the first tube;
- a second tube slidably disposed within and concentric to the first tube;
- and
- a controller operably configured to move the one or more flaps relative to the first tube between an undeployed state where the one or more flaps are contained within a cross section normal to a longitudinal axis of the first tube and a deployed state where the one or more flaps are at least in part disposed outside of the cross section to provide a mechanical separation between the distal end of the first tube and tissue surrounding a surgical site.
