DEVICE FOR DELIVERING GRAFTS AT A SURGICAL SITE

摘要

A device for delivering a synthetic mesh or graft (2) for anatomical repair at a defect site comprising a plurality of flexible arms (4) and a plurality of deflectors (60), each deflector formed of shape memory material and corresponding to one of the plurality of flexible arms, a first actuator, wherein the movement of the first actuator advances and retracts the plurality of flexible arms, and a second actuator, wherein movement of the second actuator advances and retracts the plurality of deflectors, and wherein when the plurality of deflectors are advanced from a housing (16) by the second actuator, the plurality of arms contact the plurality of deflectors and the plurality of deflectors form the plurality of flexible arms into a radial array.;In a preferred embodiment, grasping jaws (24) positioned at or near the end of the flexible arms are individually controlled at or near a proximal end of the device for connection of the graft and release of the graft at the surgical site. The flexible arms, with graft attached are positioned through a surgical incision to the defect site. An actuator positions the flexible arms to assume a radial array at the surgical site, unfolding and spreading the graft for attachment. The length of each flexible arm is individually adjustable to adapt to the size and shape of the graft selected for installation at the defect site to repair the defect.
