  • Applicator with conformable tip
    Patent number: 9877761
    Abstract: Described herein are applicators for delivery of a viscous material to a bone surface and methods of use. The applicator includes an elongate handle portion and a tip coupled to a distal location of the handle portion and formed of an elastomeric material configured to conform to the bone surface. The tip includes a bend a distance away from the distal location, a contact surface distal to the bend and including one or more surface features configured to adhere to the viscous material, and a front end having a conic curvature. The bend is between about 20 degrees to about 40 degrees from a longitudinal axis of the tip.
