Abstract
An orthopedic implant device includes an implant body with a reservoir configured store a therapeutic agent. A wall of the implant body has opposite side surfaces, including a side surface facing into the reservoir. Elution channels reach from the reservoir through the body wall. The elution channels include an elongated channel traversing a thickness of the body wall between the opposite side surfaces. The elongated channel may have a length greater than twice the thickness.
Claims51
An orthopedic implant device comprising:
- an implant body including:
- a reservoir configured to store a therapeutic agent;
- and
- a body wall having opposite side surfaces including a side surface facing into the reservoir, and further having an elution channel reaching from the reservoir through the body wall;
- wherein the elution channel reaches fully through a thickness of the body wall between the opposite side surfaces, and the elution channel has a length that is greater than twice the thickness.
An orthopedic implant device comprising:
- an implant body including:
- a reservoir configured to store a therapeutic agent;
- and
- a body wall having opposite side surfaces including a side surface facing into the reservoir, and further having elution channels reaching through the body wall between the opposite side surfaces;
- wherein the elution channels include multiple channels having a common inlet portion at the side surface facing into the reservoir, and the multiple channels reach from the common inlet portion to different respective outlet portions at an opposite side surface.
An orthopedic implant device comprising:
- an implant body including:
- a reservoir configured to store a therapeutic agent;
- a body wall facing into the reservoir and having an elution channel reaching from the reservoir through the body wall;
- and
- a reinforcement structure projecting from the body wall into the reservoir.
An orthopedic implant device comprising:
- an implant body including:
- a reservoir configured to store a therapeutic agent;
- a body wall having an inner side surface facing into the reservoir and an opposite side surface with an elution pore;
- and
- an elution pipe that projects from the inner side surface of the body wall into the reservoir, wherein the elution pipe and the body wall together define an elution channel communicating the reservoir with the elution pore.
An orthopedic implant device comprising:
- an implant body including:
- a reservoir configured to store a therapeutic agent;
- and
- a body wall facing into the reservoir and having an elution channel reaching from the reservoir through the body wall;
- wherein the body wall includes an adapter defining a passage through the body wall for injection of a therapeutic agent into the reservoir, and the adapter is configured for engagement with a luer lock fitting.
