Abstract: A propeller guard including an elongated and flexible foam block that can be folded near its center so as to engage and cover the leading edge, tip, and trailing edge of a propeller blade. A tie is secured to the foam block for selectively holding the foam block in a folded condition upon the propeller blade such that the leading edge, tip, and trailing edge of the propeller blade is retained within a channel in the block. The tie includes a belt with opposed, first and second ends. A ring is secured to the first end of the belt. A first fastening portion is secured to the top of the belt between the first end and the second end. A second fastening portion, adapted to mate with, and releasably adhere to, the first fastening portion, is secured to the top of the belt between the first fastening portion and the second end.

Abstract: An improved implant for replacing volume and transmitting motility from the remaining eye muscles to artificial eyes after eye removal. As compared to earlier implants, the mass has been redistributed which makes the implant safer and the tissues around the implant and prosthetic eye more natural appearing. The mounds of the implant are lower and more rounded, and the main body of the implant is less spherical so as to more accurately and completely fill the void left in the equatorial region around the implant by an enucleated eye. The implant remains short in the anterior-posterior dimension thereby leaving adequate space for a cosmetic prosthetic eye. Also, the implant is provided with suture holes to provide for improved surgical techniques for permanently retaining the implant in place.
