A system for restoring articular cartilage has a cover, an anchor, and a tether that cooperate to retain graft tissue with respect to a graft site. The apparatus includes storage module that stores the information collected by the information collection module. The nozzle includes a nozzle body having a melt passage therethrough, a nozzle tip having a tip melt passage therethrough, wherein the tip melt passage is in fluid communication with the melt passage of the nozzle body, and a tip surrounding piece that is removably coupled to the nozzle body. A distal leg of the balloon is directly or indirectly affixed to the inner body, and a proximal leg of the balloon is affixed to the distal end of the outer body. The at least one support member forms a crumple zone between the suspension assembly and the engine cradle. This polypropylene resin composition exhibits excellent scratch resistance, rigidity, heat resistance, and impact strength and thus, it can be suitable for automobile interior materials such as glove box, console, center crash pad and the like.
