An injection apparatus for sequentially injecting a patient with at least two medicaments may include a hand-held unit comprising a grip for being held by an operator, a single needle, a base unit coupled to the hand-held unit via at least one connecting tube, at least two containers for holding medicaments removably coupled to the base unit, and at least one pump. The at least one connecting tube can be flexible enough to enable easy maneuvering of the hand-held unit and rigid enough to prevent widening of the tube due to inner pressure when medicaments pass from the containers to the hand-held unit. The injection apparatus can be used to administer the at least two medicaments sequentially at different injection points.

Systems and methods are provided for utilizing a laser to break a kidney stones into smaller fragments and/or dust, and removing particles, stone fragments and/or stone dust from a patient. The medical device may include a delivery device including a tube, and an elongate member having a distal end, a proximal end, and a lumen extending between the proximal end and the distal end, wherein the elongate member is configured to move axially relative to the tube and apply suction through the distal end.

A device for performing a tracheotomy on a patient without the assistance of a medical professional. The device may include one or more mechanical arms that cause a blade to create an incision, cause a dilating tool to dilate the incision, and cause a tracheotomy tube to be inserted into the incision. The device may further include a scanner and/or a hollow needle connected to an air pressure sensor that may be used to detect whether the device is aligned with the patient's airway.

A microwave applicator device comprising a probe (11) for ablating the body of a human or animal, a cooling passage sage (20, 21) extending through the probe (11) and arranged to carry a cooling fluid, a pump (71) for pumping the fluid through the probe (11), and an elongate flexible duct (104) extending between the pump (71) and one end of the cooling passage (20, 21), the pump comprising a pump body (73) including a motor (120) and a pump head (72) detachably mounted to the pump body (73), the pump head (72) comprising a first port (86) connected to a proximal end of the elongate flow duct (104), a second port (85) and fluid propulsion means (84, 92) for creating a flow of fluid between the ports (85, 86) and along the elongate flow duct 104 upon energization of the motor (120), the pump head (72) being arranged to sealingly contain the fluid. The pump head (72), the elongate flexible duct (104) and the probe (11) form a replaceable assembly that can be detached from the pump body (73) and discarded following use.

A linear drive for pigmentation devices, comprising a stator, an air gap which is provided in the stator and is formed so as to be offset in a defined manner, an electric coil within the stator, said coil being designed to produce a concentration of the magnetic flux in the air gap as a result of the coil being energized, an armature which is designed to carry out sliding axial movements in the stator, and a permanent magnet which is captively connected to the armature.

A pressure sensing device includes a case provided on a liquid flow path through a liquid, a diaphragm that is provided so as to divide a space in the case into a first space with the liquid flowing therethrough and a second space filled with a gas, a pressure sensor to measure pressure of the gas, and a diaphragm initial position adjustment mechanism capable of adjusting an initial position of the diaphragm to a desired position. The diaphragm initial position adjustment mechanism includes a reciprocating pump that includes a cylinder in communication with the second space, a plunger provided so as to be able to advance and retract within the cylinder, and a plunger driving part to advance and retract the plunger, and adjusts a filling amount of the gas filling the second space by advancing and retreating the plunger in the cylinder by the plunger driving part.

A manifold assembly for a surgical gas delivery system is disclosed, which includes a manifold body including an inlet port for receiving gas from an outlet side of a compressor and an outlet port for recirculating gas to an inlet side of the compressor, a bypass valve communicating with the inlet port and the outlet port of the manifold body, an air ventilation valve for dynamically controlling the ingress of air from atmosphere, a smoke evacuation valve for dynamically controlling the egress of gas from the manifold assembly when the gas delivery system is operating in a smoke evacuation mode, and a gas fill for dynamically controlling the receipt of gas from a source of surgical gas.

A transdermal patch comprising: a microneedle in a protruding position, protruding from the transdermal patch; and immobilised functional molecules; wherein a fluid path is provided between the distal tip of the microneedle and the immobilised functional molecules; and the functional molecules are selected to interact with selected target molecules so as to convert or trap said target molecules. The device intends to dynamically curb the postprandial insulin spike offering an unprecedented therapeutic effect for diabetes and obesity with significant benefits in morbidity and without strict diet. The device offers unprecedented phenylketonuria management that removes the burden of strict diet. The device offers easy removal of autoantibodies, low density lipoprotein and other pathogenic molecules.
