Abstract: Devices, systems and methods for abdominal surgery is disclosed. The system can have a scope coupled to an introducer. The system can have one or more end effectors that can be attached to the introducer and inserted into the abdomen through a small puncture through the patient's umbilicus. The end effector can have a surgical tool, such as a grasper. The system can have a manipulatable control arm that can be inserted into the abdomen through a small puncture through the patient's body wall. The end effector can be attached to the control arm and simultaneously or concurrently detached from the introducer or tray. The control arm can then manipulate the end effector to perform the surgery.

Abstract: The various embodiments herein relate to surgical systems having a surgical tool, a detachable tool head, and an introducer tool. The various systems can be used for minimally invasive laparoscopic surgical procedures.

Abstract: The various embodiments disclosed herein relate to bone fixation or fusion devices, including intramedullary fixation or fusion devices that are implanted around the target bone. Certain device embodiments relates to devices that can be bent or otherwise deformed to replicate the natural or desired curve of the bone or joint being treated. In addition, other embodiments relate to implantation devices that can be used to implant or position the bone fixation or fusion devices.

Abstract: Methods and apparatuses for phototherapy to treat skin disorders. In particular, described herein are phototherapy dressings for use with phototherapy UV light applicators (sources) to treat skin disorders such as psoriasis. The dressings described herein may include a support body onto which a medicament formed of a hydrogel and coal tar and/or coal tar extract is held. The dressing may be configured so that at least half (50%) of the UV light within a therapeutic range of wavelengths is through the dressing including the medicament to the patient's skin. The dressings may be adapted for use in conjunction with a phototherapy UV light sources.

Abstract: An aircraft ground movement monitoring system is provided similar to that described in co-pending U.S. patent application Ser. No. 608,214, now U.S. Pat. No. 4,109,248, that makes use of an aircraft's existing SSR transponder in a hyperbolic selective interrogation technique to monitor an aircraft's position on an airfield in which, in order to overcome the problems particularly involving spurious mode C (height) interrogations that arise in long base-line systems, it is arranged that transponders that would be spuriously interrogated are interrogated first and that the required transponder is interrogated before the already interrogated transponders have finished replying.

Abstract: A secondary radar system for establishing the position and identity of aircraft etc. on airfields, particularly for controlling their ground movements during bad visibility, comprises a pair of spaced aerials each arranged to successively transmit a particular one of two interrogate pulses, the time relationship between the two pulses being varied such that a predetermined time relationship between the two interrogate pulses obtains at varying distances from said spaced aerials to afford selective interrogation of a transponder receiving the two interrogate pulses, and a third aerial spaced from the pair of spaced aerials for transmitting a further pulse in a second predetermined time relationship with one of the interrogate pulses whereby a selected transponder or transponders receiving said two interrogation pulses in said predetermined time relationship is caused to be suppressed.
