Abstract:
1. A surgically implantable device comprising: (a) a medical implant for performing a therapeutic function, the medical implant having a needle penetrable septum and a fluid reservoir; (b) an attachment mechanism comprising at least two fasteners integral to said implant for attaching said implant to a body tissue, said at least two fasteners having a deployed position and an undeployed position; and (c) an actuator operable to move the at least two fasteners from said undeployed position to said deployed position and back to said undeployed position, wherein said actuator comprises one or more cam surfaces integral to said medical implant, wherein the one or more cam surfaces are initially separate from the at least two fasteners when the at least two fasteners are in the undeployed position, wherein the one or more cam surfaces are rotatably movable along a first plane into contact with the at least two fasteners, wherein when the one or more cam surfaces are rotated in a first rotational direction upon rotation of the actuator in the first rotational direction, the one or more cam surfaces are configured to engage and push against the at least two fasteners to move the at least two fasteners to the deployed position, wherein the at least two fasteners move along one or more planes to reach the deployed position, wherein the one or more planes are not coplanar with the first plane, wherein when the actuator is rotated in a second rotational direction opposite to the first rotational direction, the actuator is operable to pull the at least two fasteners from the deployed position to the undeployed position.
