Methods and apparatus for mitral valve repair are disclosed herein where the posterior mitral leaflet is supported or buttressed in a frozen or immobile position to facilitate the proper coaptation of the leaflets. An implantable apparatus may be advanced and positioned intravascularly beneath the posterior leaflet of the mitral valve. The apparatus may include one or more individual balloon members, each of which may be optionally configured with supporting integrated structures. A magnet chain catheter may be positioned within the coronary sinus and adjacent to the mitral valve to magnetically secure the apparatus in position beneath the posterior mitral leaflet. Alternatively, a split-ring device may be placed about the chordae tendineae supporting the mitral valve such that the ring slides along the chordae tendineae alternately against the mitral leaflet and towards the papillary muscles during systole and diastole.

An endoscopic system and method that is adaptable for therapeutic applications as well as sensor operation and is capable of producing 3-dimensional human vision simulated imaging with real dynamic convergence, not virtual convergence. Applications may include use in any space, including but not limited to, intra-abdominal cavities, intra-thoracic cavities, and intra-cranial cavities. Further, two or more diagnostic/sensor probes may be used, with at least two being the same kind to create the 3-dimensional effect, such as but not limited to, camera, ultrasound, and magnetic-resonance imaging. Diagnostic/sensor probes are each mounted to the end of a different arm, with the other ends of the two arms both being attached to the same hinge that allows them to turn freely on the same axis from side-to-side within a 180 degree angle range of movement on the distal end of a main tubular shaft system. Medical, as well as other applications, are contemplated.

A reversible wrist brace includes a sheet of flexible material that overlies and supports a wearer's wrist, wherein the sheet of material includes opposing surfaces each having one or more portions of loop material. The flexible sheet has at least one opening in the vicinity of a lateral edge to accommodate at least one fastening strap, such that the strap may slide within the opening. The fastening strap is a continuous loop of sheet material having an outer surface with a hook-bearing portion. The fastener is designed so as to enable a wearer to switch the wrist brace between right and left hands by orienting the hook-bearing portion so that it is coincident with the loop-bearing portion when the wrist brace is worn on either hand. The wrist brace may include a splint that may be inserted within a pocket located on the flexible material to further immobilize the wrist.

This keyboard spill-proofing mechanism reduces and prevents damage to the electronic circuitry in keyboard that would normally occur due to inadvertent spillages of liquids, such as water, coffee or soda, onto the keyboard. This keyboard spill-proofing mechanism features a membrane sheet positioned below the top case. The membrane sheet includes multiple layers that have electrical circuits. The electrical circuits detect the off/on state of the key caps when they are pressed. The keyboard design features a waterproof base sheet made of an adhesive material that is positioned between the top case and the membrane sheet. The waterproof base sheet is designed such that a plurality of rubber springs connected thereon transmit the off/on state of the key caps to the electrical circuits in the membrane sheet. The waterproof base sheet is also designed so that it has multiple blocking portions which project upward from the waterproof base sheet so as to prevent spilled liquid from flowing downward onto the membrane sheet thereby preventing or reducing possible damage to the electrical circuits in the membrane sheet of the keyboard.

A slide hammer includes three major components, namely, a guide sleeve, a plunger and an impact head. The plunger is inserted within the guide sleeve. The impact head is secured within the distal end of the guide sleeve, and has a portion which protrudes from the guide sleeve distal end. The impact head is able to freely slide within a segmented portion of the guide sleeve distal end, or the impact head movement may be controlled by a spring. The plunger is slid within the guide sleeve at a selected velocity in order to contact the portion of the impact head slidably secured within the guide sleeve. The force of the plunger striking the impact head is transmitted through the impact head to a targeted object in contact with the protruding portion of the impact head. The impact head may be fitted with various types of tips. Each of the tips has particular advantages in applying force to a targeted object.
