  • Patent number: 10994073
    Abstract: A method of labeling an intravenous (IV) system is disclosed. The method may begin with obtaining a label. A label may be formed of a polymeric material and include a top, a bottom, and an aperture formed in at least one of the top and the bottom. At least one of the top and the bottom may have an exterior surface. The label may be applied to an IV system by closing the top with respect to the bottom such that at least one of tubing or a port of the IV system is secured within the aperture. A medical professional may then write on the exterior surface of the label a name of a medication to be administered through the IV system.

  • Patent number: 10874550
    Abstract: A method and apparatus for performing a surgical procedure is provided. The surgical procedure may be a phacoemulsification procedure but other procedures may employ the techniques disclosed. The design includes sensing, within the surgical site, for a material change in fluid flow relative to a predetermined threshold. Upon sensing the fluid flow materially differs from the predetermined threshold, the design temporarily increases aspiration vacuum pressure to the surgical site above a predetermined upper threshold toward a maximum vacuum level. The design applies electrically generated disruptive energy, including but not limited to laser and/or relatively low power ultrasonic energy, to the surgical site from a first point in time measured from when aspiration vacuum pressure is above the predetermined upper threshold to a second point in time where pressure falls below a predetermined lower threshold.

  • Patent number: 9662135
    Abstract: A fluid ejection device includes a fluid chamber, a volume varying unit, a fluid supplying unit, and an ejection pipe. The volume varying unit generates pulsation in the pressure of a fluid in the fluid chamber. The fluid supplying unit supplies the fluid to the fluid chamber through a first channel. The ejection pipe receives the supply of the fluid, in which the pulsation is generated, from the fluid chamber through a second channel and ejects the supplied fluid from an ejection port. In a connecting part to the fluid chamber, the cross-sectional area of the second channel is five times or more as large as the cross-sectional area of the first channel. In the connecting part to the fluid chamber, the first channel and the second channel are arranged to be opposed to each other via the vicinity of the center of the fluid chamber.

  • Patent number: 8389023
    Abstract: Novel methods for the chemical ablation of tissue (e.g. prostatic tissue) are described. These methods include the steps of: (a) providing one or more solid salt dosage form comprising 50-100% w/w salt; and (b) inserting one or more of such solid salt dosage forms into the tissue. The solid salt dosage form is optionally inserted into the tissue under real-time ultrasonic observation. An advantage of the present invention is its ability to eliminate toxic byproducts. For example, where NaCl-based solid salt dosage forms are used to effect localized chemical ablation, the concentration is ultimately reduced to the level of normal saline (i.e., about 0.9%) upon absorption by the body of the subject being treated.

    Abstract: The surface of a needle for collecting samples is coated with a coating material lower in chemical activity than a base metal of the needle. More specifically, the surface of the needle may be coated with a layer of gold or platinum. Alternatively, the surface of the needle may be coated with a synthetic resin coating of, for example, PEEK which is superior in chemical resistance. As a result, it is possible to obtain a practically sufficient antifouling effect even on contamination coming from chemical adsorption. Such contamination could not be removed sufficiently only by related-art measures against physical contamination. Thus, it is possible to provide an automatic sampler which can perform highly sensitive analysis.

  • Publication number: 20040193104
    Abstract: A needle device which is manufactured from shape memory or pseudo-elastic materials, such as Nickel Titanium alloys, is provided which may be formed and used repeatedly without adverse effects, such as permanent deformation or fatigue failure. The device in accordance with the present disclosure may be provided having an initial shape which a doctor may bend to a desired shape. The device may be easily returned to its initial shape after use by heating the device above a predetermined sterilization temperature. This cycle may be repeated during subsequent uses, substantially extending the life of the instrument, due to the reduced work hardening and enhanced fatigue properties of the Nickel Titanium device.

  • Patent number: 6520929
    Abstract: Sleeve apparatus for a phacoemulsification/irrigation and aspiration handpiece includes an elongate sleeve having a proximal and a distal end with a sleeve establishing an annular passage around a needle enabling irrigation fluid to pass into the eye through the passage and into the eye while cooling the needle. The elongate sleeve includes a hub disposed a proximal end for enabling attachment of the sleeve to the handpiece and a port disposed approximate the distal end and in fluid communication with the annular passage is provided for introducing irrigation fluid into the eye. An Internal circumferential berm, disposed between the port and the distal end is provided to reduce flow of the irrigation fluid therepast, to provide rigidity to the distal end of the sleeve and concomitantly provide limited contact with the needle in order to produce thermal transfer therebetween.

  • Publication number: 20020161327
    Abstract: A multi-lumen catheter and method of manufacturing such a multi-lumen catheter having a plurality of individual catheter tubes. Each catheter tube has an outer surface, an inner surface and a lumen. The catheter tubes can be made of different thermoplastic materials. A mandrel is first inserted into the lumen of each catheter tube to provide support. The catheter tubes are then juxtaposed to each other in an arrangement. Importantly, the outer surface of one catheter tube is in contact with the outer surface of at least one other catheter tube in the arrangement. The arrangement of catheter tubes is then held in a sleeve and is advanced through the sleeve, and through a heating cylinder to fuse the outer surfaces of the catheter tubes. A cooling means is placed in the lumen of each catheter tube to prevent the inner surface of each catheter tube from melting.

  • Publication number: 20020049415
    Abstract: An automatic injection device has piston holders holding cylinder pistons and plural systems of heads having a drive mechanism for moving the piston holders forward and backward so that the device can hold a plurality of syringes and operates injection or suction in each syringe independently. This device also has a mechanism for prohibiting the backward-moving of the piston holder of a second head when the piston holder of a first head is in a forward-moving state and the piston holder of the second head is in a stopped state. This structure effectively prevents liquid from being undesirably mixed and the injection amount thereof from becoming less accurate.

  • Patent number: 6299591
    Abstract: A phacoemulsification instrument that significantly reduces infusion fluid leakage by providing a silicone sleeve with a built in reinforcing member. Also, the sleeve has only a single infusion hole in order to provide better infusion fluid flow without causing turbulence in the eye. In addition, the present invention provides either a valve or a variable aperture aspiration tube in order to regulate the aspiration rate. Also, the present invention includes a single aspiration hole at the tip in order to amplify flow coming to the tip. To assist in cataract removal, the tip may be provided with a variety of different barrier and baffle configuration. A handpiece includes a variable capacity reservoir in the infusion line to account for surges in the aspiration line. The needle includes steps, angles and barriers to focus ultrasonic energy to aid in emulsifying nuclear tissue and to aid in pushing emulsified material in the direction of aspiration flow.
