Abstract

A method for delivering a graft or synthetic mesh for anatomical repair to the repair site, with the graft or synthetic mesh in position for attachment to repair the defect. A plurality of spaced apart, flexible fingers is connected to the graft or synthetic mesh. The flexible fingers are initially in a position that is generally parallel to a direction of travel of the actuator. The actuator moves the plurality of flexible fingers from the initial to form a radial array, which opens or extends the graft or synthetic mesh. The graft or synthetic mesh may then be attached. A novel trocar is disclosed that is useful with the device. A measuring device including a measuring scale that is useful for determining the required size of the graft is also disclosed.

Claims19

Dependent claims

A method of delivering a graft for attachment to tissue, comprising:

attaching a graft to a plurality of spaced apart, flexible fingers;
delivering the graft to a site of an anatomical defect by extension of the flexible fingers from side by side positioning of the plurality of spaced apart, flexible fingers to a radial array of the plurality of spaced apart, flexible fingers and forming the graft to cover the anatomical defect;
wherein extension of the spaced apart, flexible fingers is controlled by a plurality of control wires, wherein each of the control wires is connected to one of the flexible fingers at a distal end of the control wires and proximal ends of the control wires are in a fixed position relative to the flexible fingers as the flexible fingers extend from the side by side position to the radial array, causing the control wires to exert a force on the flexible fingers and pull the flexible fingers into a radial array.

Dependencies are inferred from the claim text.
