In a marking pen, the body of the marking pen containing the cartridge is made air tight except for the opening on the distal end to receive the marker nib and a vent hole. The walls of the pen body are made flexible and the vent hole is provided through the flexible walls near the distal end so that the cavity containing the cartridge can be pressurized by squeezing the body between the thumb and index finger, with the index finger covering the vent hole. The pressuring of the cartridge cavity applies hydraulic pressure to the nib to flush the nib with ink or unclog it.

Marker pen

A implant for cranioplasty made of porous high density polyethylene is provided. The implant has a smooth upper surface and a lower surface characterized by a plurality of conical extensions. The implant is flexible so that it can conform to the contour of the cranium and can be cut with a scalpel or surgical scissors or bone cutters. The shape of the implant allows a surgeon to easily adapt the implant to fit into cranial defects such as those caused by harvesting bone grafts.
