Abstract: Cross stream thrombectomy catheter and system for fragmentation and removal of thrombus or other material from blood vessels or other body cavities. High velocity saline jets emitted from a toroidal loop jet emanator or other jet emanator in a catheter distal end entrain fluid through inflow orifices, and with flow resistances create a back-pressure which drives cross stream streams through outflow orifices in a radial direction and thence radially and circumferentially to apply normal and drag forces on thrombotic deposits or lesions in the blood vessel or other body cavity, thereby breaking apart and transporting thrombus particles to be entrained through the inflow orifices, whereupon the high velocity jets macerate the thrombus particles which then transit an exhaust lumen or recirculate again via the outflow orifices.

Abstract: A railroad gate release mechanism which attaches between the mount arms of a railroad gate actuator and a crossing arm to prevent breakage of the crossing arm due to impingement by a vehicle. The railroad gate release mechanism includes a pivotable arm assembly which allows released movement in two directions of the crossing arm in reaction to impingement and returns the crossing arm to the original and detented position subsequent to impingement to maintain grade crossing protection. An alternative embodiment includes a pair of swing plates and an elongated arm to which is attached a crossing arm, the elongated arm with the attached crossing arm is pivoted to the pair of swing plates in such manner that the elongated arm and attached crossing arm can be pivoted aside without moving the swing plates for crossing arm maintenance without impeding vehicular traffic flow across the grade crossing.

Abstract: A system for generating, delivering and distributing electrical power to network elements over a data communication network infrastructure within a building, campus or enterprise. Consolidating power distribution and data communications over a single network simplifies and reduces the cost of network element installation and provides a means of supplying uninterrupted or backup power to critical network devices in the event of a power failure. The invention includes power/data combiners that combine a data communication signal with a low frequency power signal. The combined signal is transported over the LAN infrastructure where a power/data splitter extracts the data signal and the power signal and generates two separate outputs. The power over LAN system of the present invention operates with high bandwidth data communication networks, i.e., 10 Mbps, 100 Mbps, 1000 Mbps.

Abstract: The present invention provides for a device, a method, and a treatment system for chronic disease conditions. The present invention was designed using the theoretical concepts of Quantum Biology. The principles of operation are based on the device's ability to stimulate a Bose-Einstein condensate and excitation of Frolich resonance in living tissue The wavenumbers necessary for this excitation are derived from the solution to the equations for optical phonon scattering in living tissue generated by optical photon excitation. The establishment of this degeneracy condition induces a super conducting state in the tissue. This super conducting state facilitates DNA replication, transcription and translation, thereby allowing the proper formation or regeneration of healthy tissue. This superconducting state provides the conditions necessary for establishing the violation of time reversal invariance in living tissue.

Abstract: A method of and apparatus for removing a thrombus deposit from the cardiovascular system of a patient without the need to surgically access the location of the thrombus deposit via a cut-down or other surgical procedure. A catheter is inserted percutaneously into the patient at a convenient location either directly or over a previously positioned guide wire. The distal end of the catheter is advanced under fluoroscopy to the site of the thrombus deposit. A balloon is inflated to stabilize the position of the distal end of the catheter within the center of the vessel lumen. A flexible metal tube conveys an extremely high pressure stream of sterile saline solution to at least one jet at the distal end of the catheter. At least one jet positions the thrombus deposit for emulsification by at least one other jet. By directing the jets toward the orifice of the large evacuation lumen of the catheter, a stagnation pressure is induced which propels the emulsion proximally for disposal.

Abstract: A device for removing a thrombus or other tissue deposit from the cardiovascular system, natural or synthetic tubule or cavity found in the human body of a patient without the need to surgically access the location of the thrombus or other tissue deposit via a cut-down or other surgical procedure. A flexible metal or high pressure plastic tube conveys an extremely high pressure stream of sterile saline or other physiologic solution to at least one jet at the distal end of the catheter. At least one jet is directed at the opening of a large exhaust lumen or other target. The jet(s) is responsible for providing a localized negative pressure which entrains tissue into the jet from break-up of the debris. This jet(s) can also provide stagnation pressure in the exhaust lumen which drives the tissue or thrombotic debris out of the exhaust lumen. Operation of the device with tip pressure greater than 500 psi provides this device with the entrainment and exhaust characteristics which contribute to its effectiveness.

Abstract: A bat weight and protector which is a removable soft-sided weight and protector for the attachment to a baseball or softball bat for the purpose of warming up a batter in the on-deck circle, prior to entering the batter's box and facing the pitcher. The bat weight and protector is comprised of a soft weighted cylindrical portion made of rubber or other suitable material, a retainer ring and webbing straps, which at one end are equally spaced around a retainer ring and stitched thereto, and at the opposite end are looped around the cylindrical portion and stitched thereto. A knob end of a bat is passed through the cylindrical portion of the bat weight and protector and further through the retainer ring until the tapered portion of the bat prevents further travel. In this position, the cylindrical portion of the bat weight and protector is over and about a barrel of the bat. This position maximizes the batter's swing resistance during warm-ups and protects the striking surface of the bat.
