摘要： Devices and methods useful for storing and retrieving information related to a medical device such as an implantable valve or an implantable sensor are disclosed. An implantable valve can include a valve housing adapted to receive fluid flow therethrough between a valve inlet and a valve outlet. A valve assembly can be disposed within the valve housing and adapted to control a rate of fluid flowing through the valve housing. The implantable valve can also include a radio frequency identification (RFID) tag associated with the valve housing, adapted to store data, and including an antenna for communicating stored data to an external reading device. The RFID tag can store data related to, for example, a patient, a pressure setting of the valve assembly, and/or pressure sensor disposed within the valve. The RFID tag can also store an identifier that identifies the implantable valve, a pressure sensor disposed in the valve housing, a patient associated with the implantable valve, and/or patient clinical history.

摘要： An implantable valve system and method of using same, including a housing with a resilient membrane defining a reservoir in fluid communication with at least two ports, and at least a first set of opposing sealing features disposed on upper and lower surfaces within the housing. The membrane is capable of being depressed by a human finger to bring the sealing features together to substantially restrict fluid from passing through at least one of one of the ports, and is capable of being depressed additionally by a rolling motion of the finger to drive fluid through the other of the ports.

摘要： A valve unit capable of being implanted in a patient and having adjustable performance settings, such as pressure settings and/or flow control, to regulate passage of a bodily fluid. A casing defines a port for the bodily fluid, and a valve mechanism positioned at the port includes a movable valve member. The valve unit further includes a rotor disposed at a first location in the casing and having an axle which turns about an axis of rotation. The rotor defines a plurality of arcuate, radially flat cam surfaces. Each cam surface occupies an arc about the axis of rotation. A spring arm unit is disposed at a second location in the casing having a cam follower arm in slidable contact with the cam surfaces of the rotor and having a resilient spring element applying a closing effect with the movable valve member to establish a performance setting for the valve unit. Sufficient rotation of the rotor to change the cam surface in contact with the cam follower alters the closing effect with which the valve member moves relative to the port and thereby alters the performance setting of the valve unit.

摘要： A catheter is provided having a plurality of fluid entry ports formed therein and in communication with an inner lumen of the catheter. One or more of the fluid entry ports includes a fluid-permeable barrier extending there across. In a preferred embodiment, a set of conductive members is embedded in the wall of the catheter and connects each barrier to a control unit. In the event of blockage in the catheter, an external power source can non-invasively command the control unit to transmit an electric current to one or more of the barriers to dissolve or otherwise remove the barrier, thereby allowing fluid to once again flow through the catheter.

摘要： A percutaneous access device is provided including a sleeve having an inner lumen extending therethrough that is adapted to slidably receive a catheter, and at least one flange disposed around the sleeve and adapted to be positioned adjacent a tissue surface. In a preferred embodiment, the device includes a first flange disposed around the sleeve and adapted to be positioned adjacent a first tissue surface, and a second flange disposed around the sleeve and spaced apart from the first flange such that the second flange is adapted to be disposed adjacent a second tissue surface opposed to the first tissue surface. In use, the flanges 16, 18 are positioned on opposed sides of tissue so that the device 10 is effective to prevent tissue surrounding the percutaneous access device from coming into contact with the catheter as it is introduced through the sleeve 12. The device also includes an antimicrobial agent that is effective to protect against bacterial colonization on and around the access device, the catheter, and the tissue surface surrounding the access device.

摘要： An implantable fluid management device includes a catheter with an elongate proximal portion, a flexible distal portion, and a fluid passageway flowing therethrough. The distal portion includes a coil-shaped portion that defines a spiral having at least one turn. The distal portion of the catheter includes at least one pore in fluid communication with the fluid passageway of the catheter, which is located on an internal portion of the spiral. The positioning of the pore(s) on the internal portion of the spiral protects the pore(s) from obstruction or occlusion caused by tissue growing into or around the catheter.
