DEFINITION

Classification: 427/2.24

Implantable permanent prosthesis (i.e., artificial body member) (e.g., pacemaker, lens, cornea, glaucoma shunt, heart valve, muscle, spinal disc, breast, internal organ):

(under subclass 2.1) Processes in which the product is an implantable artificial body member or a part or subcombination thereof, which is intended to physically replace a missing or defective natural body member or part by insertion into the body or attachment onto epidermal tissue in a permanent manner; parts, subcombinations, or intermediates thereof or therefor.

(1) Note. This subclass and its indents are intended to provide for all appropriate processes under subclass 2.1 wherein the product would be found in Class 623 and which is intended to be inserted into the body in a permanent manner, unless proper for a subclass appearing above this one.

(2) Note. Prosthesis herein means a replacement or assistant for a missing or defective part of a living body.

(3) Note. Artificial skin intended to remain on the body; e.g., be absorbed, is placed here.

(4) Note. In the case of generic claims and multiple disclosed utilities, multiple cross-referencing is required; for example, coating of a material disclosed for heart valve, vascular prosthesis, blood bag or IV tubing.

2.1, for similar subject matter which is not intended to be permanently implanted; e.g., splint. 2.24, for coating of a material disclosed for heart valve

2.3, blood bag or IV tubing

2.5, vascular prosthesis.

2.29, for similar subject matter relating to dentistry which is not intended to be permanently implanted.

164+, for coating processes relating to optical lenses not intended to be implanted, such as corrective or contact.

prosthesis; subclass 12 for implantable hollow or tubular part or organ prothesis; subclass 13 for implantable ligament or tendon prothesis; subclass 14 for implantable muscle prothesis such as sphincter; subclass 15 for implantable hair or skin prothesis; and cross-reference art collection 901 for documents relating to a process for making an artificial body member.
