A system for implanting a prosthetic device with an opening into a bone includes a plug that is removably received within the opening of the prosthetic device. In particular, the invention relates generally to a medical device for delivering a biologically active material to a surface of a body lumen. These slits are arranged on mutually overlapped positions. The walls of the device are transparent and vented to allow the dynamic characteristics of the water to be seen from outside the device and to allow the sonic characteristics to be heard from outside the device. If a text suggestion is selected, the accessory can send the selected text to the portable computing device for populating the text field. Using the inventive filter network, it is possible to manufacture low cost and small size dudt-filters generating low voltage overshoot and low losses.
