An improved composite prosthesis for laparoscopic repair of inguinal or femoral hernias, and also for the laparoscopic repair of large incisional ventral hernias incorporates two different layers, namely an upper layer made of polypropylene mesh to promote tissue ingrowth, and a lower layer formed with an adhesion barrier material to prevent adhesions to the intestines. Both layers are secured together with a highly visible dark seam at the perimeter of the prosthesis to assist the surgeon in visualizing the peripheral edge. The lower layer is slightly larger than the polypropylene mesh so there is an adhesion barrier edge around the prosthesis to conceal the edges of the polypropylene mesh. The upper layer includes a guiding cone to facilitate placement of the prosthesis at the exact center of the hernial defect. The base of this cone is attached to the central part of the prosthesis, and the apex of the cone will be attached later to a guiding thread that is inserted to from the outside of the abdomen using a long straight needle through the skin and hernial sac. Furthermore the laparoscopic hernia prosthesis lower layer is provided with a bounding rim to guide the tip of the spiral tacker to the very edges of the prosthesis in order to stretch the prosthesis in place, and also to conceal the staples or tacks.

A transabdominal needle introducer for the repair of large ventral incisional hernias comprises a handle connected to a long tubular shaft and a disposable needle cartridge at its distal end. The handle has a round knob or head, and a needle pusher to extrude the needles out. The long tubular shaft contains two metal rods disposed inside thereof, one to change the angle of the cartridge, and the other one to extrude the needles. At the proximal end of the tubular shaft there is a rotatable cylindrical control provided with a spiral groove that moves a metal rod destined to pivot the needle cartridge. The second metal rod inside the shaft is assigned to extrude the needles and is connected to a flexible resilient wire that protrudes at the distal end of the tubular shaft and is provided at its distal end with an oval tip that engages a piston-type pusher inside the needle cartridge. There are two straight needles inside the cartridge that are attached to a single strand of suture at each end, and they can be extruded by action of the needle pusher.

A surgical multipurpose knot pusher that allows an extracorporeal knot to be slid down around a limb of suture without deforming or collapsing the knot. This knot pusher includes a handle portion and an elongated shaft extending from the handle portion to the distal part of the instrument. This distal part is provided with two jaws and one of them, the lower one, has a shallow oblique groove. With the jaws open the suture thread is placed in the shallow oblique groove and then retained captive when the jaws are closed. The jaws of the instrument can incorporate a suture cutter in the form of small scissors.

An implantable hernial prosthesis having top and bottom layers and a central sleeve to facilitate manual expansion and placement of the prosthesis within an incision in a patient. The top layer and a bottom layer are secured together with at least one seam at the perimeter of the prosthesis. The top layer is made of a synthetic mesh, preferably polypropylene mesh, to promote incorporation into the abdominal wall, and the bottom layer is made of the same material or in some cases of a mechanical barrier to prevent adhesions to the intestine. The top layer is provided with a central sleeve to introduce one or two fingers to expand the prosthesis in place, and also to introduce an articulated hernial stapler to secure the mesh into the abdominal wall.

An apparatus for magnetic therapy of eye conditions such as cataracts, eye floaters, chronic glaucoma, age-related maculopathy, diabetic retinopathy, dry eyes, watery eyes and myopia is disclosed. The apparatus comprises a combination of two bi-polar magnets enclosed in a supportive cover that saddles the upper rim of regular eyeglasses. The magnets are placed in a proper position in front of the affected eye and their polarity can be changed at any time without any difficulty. The magnets are preferably solid discs of Neodymium-Iron-Boron (NdFeB) with a surface strength of 1300 to 1800 gauss.

This is a seat belt system for a motor vehicle which has a belt retractor behind the inboard rear corner of the seat, a belt guide next to the inboard side of the head rest, a slip ring on a slide in an upwardly and forwardly inclined guideway in the vehicle door next to that seat, and an anchor next to the inboard side of the seat in front of the belt retractor. The seat belt extends up from the retractor behind the back rest of the seat, slidable through the belt guide at the inboard side of the head rest, downward and laterally outward diagonally across the front of the back rest from the guide to the slide on the door, and slidably through the slip ring on that slide back across the seat to the anchor.

An alphanumeric data input system for entering text into portable electronic devices by making linear traces or taps with a thumb or finger on a touch sensitive lineographic keypad. This keypad is conveniently located on the upper and left part of the electronic device in order to facilitate the natural motion of the thumb thus avoiding fatigue and strain of the same. The system allows the user to enter operational commands on the keypad, as well as entering of letters of different alphabets such as the Latin Alphabet, Mathematical Greek and Russian Alphabets and possibly of alphabets of other foreign languages including Japanese, Chinese and Korean. This system can be used for entering a combination of letters to speed up the writing process, and enables the entering of punctuation marks, typographical symbols and a wide range of mathematical symbols.

This is a door lock arrangement which is operated by a slide on a vehicle door, which slide is the actuator of a seat belt system for a seat next to the door. As the door is closed, the slide moves along the door to operate this door lock as well as to put the seat belt system in its operating position restraining a person who is sitting on this seat. The door lock includes a socketed keeper mounted on a door post behind the door, a holder mounted on the door, a lock bolt slidable in this holder and engageable in the socket of the keeper, and a spring biasing the lock bolt out of engagement with the keeper and into the path of movement of the slide as the door is closing.
