Abstract: The present disclosure provides a plasma catheter including a tubular member; a conductive cylindrical member; a first electrode; and a second electrode. The tubular member defines a longitudinal lumen therethrough and has a proximal portion and a distal portion. The conductive cylindrical member is disposed at the distal portion of the tubular member. The first electrode is embedded in a first side of the tubular member and coupled to the conductive cylindrical member. The second electrode is embedded in a second side of the tubular member diametrically opposed to the first side.

Abstract: The invention generally provides a fluid delivery system comprising: a reservoir (7); a pumping chamber (8) having a volume, an inlet valve (48), an outlet valve (49) and a membrane (47); an actuator (20); and a drive member (21). The inlet valve and the outlet valve each comprise a passive normally closed one-way check valve. The inlet valve provides selective fluid communication between the pumping chamber volume and the reservoir. Fluid in the reservoir is at substantially ambient pressure. The drive member is operatively coupled to the pumping chamber membrane. Energising the actuator moves the drive member in reciprocating motion and thereby displaces the membrane to change the pumping chamber volume between a minimum volume and a maximum volume. The pumping chamber volume is held at a pressure above the ambient pressure in the reservoir when the actuator is at rest.

Abstract: A neutral pressure split-septum luer access device is described for receiving a luer lock connector. The septum has a plurality of elastomeric columns projecting laterally within a chamber. Each elastomeric column is under sufficient compression so that the columns are bowed and the column strength is reduced by bowing, but the slit sealing force is high. This configuration places the lower portion of the slit in a tightly sealed configuration which is never-the-less receptive to penetration by the male luer which causes the columns to bow further and collapse precipitously with the elastomeric force of the collapsing mass of the columns being carried distally to displace and pop open the central slit distal the tip of the male luer. The septum further provides a transverse separation between the columns and a distal sealing portion so the force of the displacement force to the sealing portion is reduced.

Abstract: This disclosure concerns polymer catheter designs incorporating joints that break under tension. The joints are generally formed from two tubular elements comprising two different polymers with dissimilar thermal and/or mechanical characteristics, which are overlapped and exposed to heat and pressure.

Abstract: A needleless syringe for injecting an injection objective substance into an injection target area of a living body is provided. The syringe includes an enclosing unit enclosing the injection objective substance, and an ignition device including an ignition charge and flowing an ignition current so that the ignition charge is combusted. The syringe also includes a pressurizing unit pressurizing the injection objective substance, and a flow passage unit defining a flow passage so that the pressurized injection objective substance is allowed to inject to the injection target area. The pressurizing unit raises a pressure applied to the injection objective substance to a peak pressure for the injection objective substance to penetrate through a surface of the injection target area and then lowers the pressure applied to the injection objective substance to a waiting pressure within 2 msec after the ignition current was allowed to flow to the ignition device.

Abstract: A method and system for delivering a molecule to a specific area of a tissue by controlling temperature and impedance is presented. The method is generally comprised of applying heat to a biological structure, such as cells or tissues, to heat the biological structure to a preset temperature after which at least one electroporation pulse is administered to the biological structure. Impedance is measured as a feedback control mechanism after each pulse and pulse parameters are adjusted accordingly until desired impedance is reached. The system generally comprises an electroporation system capable of generating at least one pulse, measuring impedance and measuring temperature.

Abstract: An IV catheter system may have a catheter component and a needle component. The catheter component may have a catheter hub, a cannula extending distally from the catheter hub, and a push feature extending outward from the catheter hub. The push feature may have an outer surface that receives contact from a digit to move the IV catheter system from an insertion configuration, in which the needle is within the cannula, to a fluid delivery configuration, in which the needle is outside the catheter hub. The needle component may have a needle hub and a needle extending distally from the needle hub along an axis. The push feature may be formed of a flexible material that causes the push feature, in response to pressure exerted on the outer surface by a dressing securing the catheter component to a patient, to deflect the outer surface toward the cannula axis.

Abstract: Tissue is resected and extracted from an interior location in a patient's body using a probe or tool which both effects resection and causes vaporization of a liquid or other fluid to propel the resected tissue through an extraction lumen of the resecting device. Resection is achieved using an electrosurgical electrode assembly including a first electrode on a resecting member and a second electrode within a resection probe or tool. Over a first resecting portion, radio frequency current helps resect the tissue and over a second or over transition region, the RF current initiates vaporization of the fluid or other liquid to propel the tissue from the resection device. In one embodiment, an extending element extends from a housing and into a channel in a resecting member as the resecting member moves toward a distal position.
