Автор: Scott L. Kalpin

Принадлежит: MEDTRONIC INC

Disclosed are methods and systems for automatically estimating the length of an implantable catheter by measuring the pressure decay response to pumping fluid through the catheter. The decay time for a unit fluid pressure pulse generated within the catheter is proportional to the catheter length, i.e. as the catheter length increases so does the decay time. The catheter length can therefore be estimated based on, e.g., the decay time of the pressure pulse. The estimated catheter length can also be analyzed to determine if it is representative of the actual catheter length, or, e.g., is affected by one or more catheter malfunctions including cuts and occlusions. Systems for automatically estimating the catheter length include an implantable catheter, a pumping mechanism, a pressure sensor configured to measure pressure within the catheter, and a processor that calculates the catheter length from a pressure pulse measured while delivering fluid through the catheter.

Micromechanic passive flow regulator

Номер: US20120316492A1

Автор: Eric Chappel

Принадлежит: Debiotech SA

The invention concerns a flow regulator, made of a stack of 3 plates, respectively a top plate including a flexible membrane ( 1 ), a middle plate ( 2 ) with pillars and through holes and a bottom plate ( 3 ) with fluidic ports, micro channels and through holes ( 8,9,12 ). The principle is based on the deformation of the membrane due to the pressure of the liquid. The membrane goes in contact with the pillars of the middle plate, obstructing gradually the through holes of the pillars. The device is designed to keep the flow constant in a predefined range of pressure. The device is dedicated to ultra low flow rate up to 1 ml per day or below, typically for drug infusion. Plastic flow regulators comprise preferably several independent valves coupled in parallel. The membrane plate is therefore made of several flexible membranes obstructing gradually the flow by increasing the pressure. Stress limiters are used to avoid plastic deformation of the membrane. For implanted pump, the use of a flow regulator instead of a flow restrictor has several advantages, including the possibility to reduce significantly the reservoir pressure and to generate directly the pressure during the pump filling by using an elastic drug reservoir.

A pressure sensor suitable for use in a powered contrast injector system may be tested to help validate the operability and/or integrity of the sensor. In some examples, the pressure sensor may be tested by generating a pressure pulse in a fluid line fluidly connected to the pressure sensor so as to generate a first pressure reading. A high pressure fluid at a pressure above a maximum operating pressure of the pressure sensor may be conveyed through a valve fluidly connected to the pressure sensor. Subsequent to conveying the high pressure fluid through the valve, the pressure sensor may again be tested by generating a pressure pulse in the fluid line fluidly connected to the pressure sensor so as to generate a second pressure reading. In some examples, the first pressure reading is compared to the second pressure reading to determine whether the pressure sensor has passed or failed.
