1. An device for use with a medical implant for delivering an agent to a designated site of action in a body of a patient, the agent-delivery device comprising:
-
a body member adapted to be secured to the medical implant; and an agent-delivery component associated with the body member, the agent-delivery component including a therapeutic agent for treating the body of the patient, wherein the agent-delivery component is configured to release the therapeutic agent after implantation in the body of the patient. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 13, 14, 15)
legs extending from the longitudinal edges of the base portion and terminating in longitudinal edges, the legs extending from the base portion at an acute angle such that the base portion and the legs define an open longitudinal channel narrower at the edges of the legs than at the base portion, wherein the longitudinal channel is adapted to slidably receive the medical implant.
-
-
3. An agent-delivery device as recited in claim 1, wherein the body member comprises
a base portion terminating in longitudinal edges; -
legs extending from the longitudinal edges of the base portion and terminating in longitudinal edges, the base portion and the legs defining an open longitudinal channel; and a flange integral with the longitudinal edges of each leg, the flanges extending inwardly such that the base portion, legs, and flanges define opposed longitudinal slots, wherein the longitudinal channel and slots are adapted to receive the medical implant.

-
4. An agent-delivery device as recited in claim 1, wherein the body member comprises a bio-absorbable polymer.
-
5. An agent-delivery device as recited in claim 1, wherein the body member comprises a non-bio-absorbable polymer.
-
6. An agent-delivery device as recited in claim 1, wherein the agent-delivery comprises a carrier for the therapeutic agent.
-
7. An agent-delivery device as recited in claim 6, wherein the carrier comprises a sponge.
-
8. An agent-delivery device as recited in claim 1, wherein the agent-delivery component comprises at least a portion of the surface of the body member having the therapeutic agent impregnated thereon or adsorbed thereon or otherwise contained therein, and wherein the agent desorbs, elutes, or is otherwise delivered from the body member to a site of action.
-
9. An agent-delivery device as recited in claim 1, further comprising an insert having an axis defined in a direction of insertion, the insert comprising:
-
a plurality of legs depending from the inner surface of the body member and along the insert axis, the outer dimensions of the legs having a profile adapted to be received in a hole in the medical implant, the length of the legs adapted to be longer than the thickness of the area of the medical implant defining the hole; and outwardly extending flanges at a distal end of the legs, the outer dimensions of the flanges having a wider profile than the legs relative to the insertion axis, wherein the insert is adapted to be received in the hole in the medical implant, the flanges adapted for contacting the implant adjacent the hole during insertion for flexing the legs resiliently inwardly for reducing the outer dimensions of the flanges such that the flanges pass through the hole and the flanges contact the opposite side of the medical implant adjacent the hole for a snap-fit securing the agent-delivery device relative to the medical implant.
-
-
10. An agent-delivery device as recited in claim 1, further comprising:
-
opposed arcuate walls depending from a surface of the body member, the walls defining a partial tube and a longitudinal slot extending between the length of the terminal edges of the walls, wherein the walls are adapted to receive a cylindrical medical implant, the walls flexing resiliently outwardly when pressed against the medical implant for enlarging the slot and receiving the medical implant between the walls such that the agent-delivery device is secured relative to the medical implant.
-
-
11. An agent-delivery device as recited in claim 1, wherein the body member comprises
a first base portion and a second base portion, each base portion terminating in longitudinal edges defining a transverse slot in one edge, and including at least one leg extending from the edge of each base portion opposite the slot and terminating in a longitudinal edge, a flange integral with the longitudinal edge of the at least one leg, the flange extending inwardly such that each base portion, the at least one leg, and the flange define a longitudinal slot for receiving a medical implant, a tongue integral with each base portion, and means operatively associated with each slot for securing the tongue at a plurality of relative positions of the base portions, wherein the tongues are configured to be received in a respective slot for securing together the first base portion and the second base portion such that the first and second base portions and the legs define an open longitudinal channel adaptable to the width of the medical implant. -
13. An agent-delivery device as recited in claim 1, further comprising an agent-delivery system including at least one reservoir and having a valve in fluid communication with an orifice opening into the reservoir.
-
14. An agent-delivery device as recited in claim 13, further comprising a magnetic element associated with the valve, wherein when the device has been placed within the body of a patient, the location of the valve can be located from outside the body of the patient using a triangulation technique for introducing the agent to the reservoir via the valve by a tubular member.
-
15. An agent-delivery device as recited in claim 13, wherein the tubular member is selected from a cannula, a rod, a shaft, and a needle.
-
16. A system for use as a medical implant, the medical implant system comprising:
-
a medical implant; a device for delivering an agent to a designated site of action in a body of a patient, the agent-delivery device comprising; a body member configured to be secured to the medical implant, and an agent-delivery component associated with the body member, the agent-delivery component including a therapeutic agent for treating the body of the patient, wherein the agent-delivery component is configured to release the therapeutic agent after implantation in the body of the patient. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
-
-
35. A method of delivering a therapeutic agent to a site within the body of a patient adjacent to a medical implant, the method comprising the steps of:
-
providing a medical implant; providing a therapeutic agent to be delivered to a site of action within the body of a patient; providing an agent-delivery device; operatively associating the therapeutic agent with the agent-delivery device such that the therapeutic agent is arranged to delivery a therapeutically effective amount of the agent to the site; securing the agent-delivery device to the medical implant; and surgically implanting the medical implant. - View Dependent Claims (36, 37, 38, 39, 40, 41, 42)
