  • Publication number: 20160279396
    Abstract: Tools for determining and adjusting the setting of an adjustable valve are disclosed. These tools allow a medical professional to locate and non-invasively determine the setting of an implanted valve. After the valve has been located and the setting of the valve determined, the valve may be re-adjusted non-invasively. There are three tools: a locator tool, an indicator tool and an adjustment tool. The locator tool allows the physician to locate the adjustable valve of interest and align the locator tool with a specific orientation of the valve. The indicator tool indicates the current setting of the adjustable valve and confirms new settings of the valve after the new settings have been implemented. The adjustment tool interacts magnetically with the implanted adjustable valve to couple with a movable internal element to change the setting of the valve. The indicator tool and the adjustment tool physically cooperate with the locator tool to accomplish the respective functions of the tools.

  • Patent number: 6029663
    Abstract: A powder storage and delivery system for a drug powder inhaler has a carrier disk with a blister shell sealed by a shear layer. A tab is adhered to the shear layer, underneath the blister shell. The carrier disk is placed into a dry powder inhaler. An actuator pushes against the tab, causing the shear layer to tear away, releasing the powder drug contents from the blister into the dry powder inhaler. A disk carrier has bursting blisters with a brittle blister shell sealed with a foil lid, and covered by a plate. An actuator moves against the plate, causing the plate to buckle and the blister shell to burst open, releasing powdered drug into the dry powder inhaler.
