  • Patent number: 8920388
    Abstract: An apparatus provides feedback regarding the material in which tip of the apparatus is located as the tip is advance into matter of varying resistances. The apparatus responds to a change in pressure, force, or other parameter such that when the tip reaches matter of a certain resistance, a change in the parameter is sensed. The apparatus provides a driving force to a penetrating medical device, such as a needle, when the apparatus tip encounters material of high resistance. When the apparatus tip encounters a low resistance material, no further driving force is applied to the apparatus. An inner core may be advanced into the low resistance material for deployment of a gas or a liquid as desired.

  • Patent number: 8777924
    Abstract: An infusion system, which may be a closed loop, or “semi-closed-loop”, infusion system, uses state variable feedback to control the rate at which fluid is infused into a user's body. The closed loop system includes a sensor system, a controller, and a delivery system. The “semi-closed-loop” system further includes prompts that provide indications to the user prior to fluid delivery. The sensor system includes a sensor for monitoring a condition of the user and produces a sensor signal which is representative of the user's condition. The delivery system infuses a fluid into the user at a rate dictated by the commands from the controller. The system may use three state variables, e.g., subcutaneous insulin concentration, plasma insulin concentration, and insulin effect, and corresponding gains, to calculate an additional amount of fluid to be infused with a bolus and to be removed from the basal delivery of the fluid.

  • Patent number: 8764713
    Abstract: A method of repositioning an injection port comprises positioning the injection port at a first location in a patient's body and extending fasteners of the injection port to substantially secure the injection port at the first location. The fasteners are then retracted to substantially unsecure the injection port from the first location in the patient's body. The injection port is then moved to a second location in the patient's body. The fasteners are then re-extended to substantially secure the injection port at the second location in the patient's body. The injection port includes a port body. The fasteners are integral with the port body. The fasteners may be selectively extended and retracted relative to the port body. For instance, the fasteners may be pivoted relative to the port body to transition between extended and retracted positions. The extension and retraction of fasteners may be provided through a port applier.

  • Patent number: 8758303
    Abstract: An injection port system comprises an injection port and an applier. The port comprises a body and a plurality of fasteners. The fasteners are integral with the body and are movable from a non-deployed position to a deployed position. The applier comprises a port engagement portion and an actuator. The port engagement portion is configured to selectively engage the port body to selectively retain the port relative to the applier. The actuator is operable to move the fasteners to the deployed position. The applier is also configured to disengage the port engagement portion from the port body to release the port from the applier when the actuator moves the fasteners to the deployed position. The actuator may release the port from the applier by moving a resilient member away from the port body as the actuator also moves the fasteners from the non-deployed position to the deployed position.

  • Patent number: 8715230
    Abstract: Devices and methods for balloon delivery of rapamycin and other hydrophobic compounds to the wall of blood vessels. Balloon catheters, such as those used for balloon angioplasty, are modified with the addition of a reservoir of dry micelles, disposed at a suitable location within the balloon or catheter. The reservoir may be installed within the angioplasty balloon, within a lumen in communication with the angioplasty balloon, either as a loose or packed powder or as a film coating. The micelle preparation is reconstituted and the micelles are mobilized when the aqueous solution used to inflate the balloons is injected into the catheter. The micelles are infused into tissue surrounding the balloon when pressurized fluid within the balloon leaks through the wall of the balloon.

The port engagement portion is includes a fastener deployment member that is operable to move the fasteners to the deployed position. The handle comprises a first handle portion and a second handle portion. The second handle portion is movable distally relative to the first handle portion in order to actuate the fastener deployment member, to thereby move the fasteners to the deployed position. An elongate actuating member couples the second handle portion with the fastener deployment member. One part of the elongate actuating member translates longitudinally in response to the second handle being moved distally; while another part of the elongate actuating member rotates in response to the first portion translating.

  • Patent number: 8708966
    Abstract: Microneedle devices are provided for transport of molecules across tissue barriers and for use as microflameholders. In a preferred embodiment for transport across tissue, the microneedles are formed of a biodegradable polymer. Methods of making these devices, which can include hollow and/or porous microneedles, are also provided. A preferred method for making a microneedle includes forming a micromold having sidewalls which define the outer surface of the microneedle, electroplating the sidewalls to form the hollow microneedle, and then removing the micromold from the microneedle. In a preferred method of use, the microneedle device is used to deliver material into or across a biological barrier from chambers in connection with at least one of the microneedles. The device preferably further includes a means for controlling the flow of material through the microneedles. Representative examples of these means include the use of permeable membranes, fracturable impermeable membranes, valves, and pumps.
