    摘要: A catheter for delivery of a therapeutic agent directly into a targeted tissue that reduces or substantially prevents reflux and back flow by providing rigidity and strength via a stylet thereby eliminating the need for a guide or delivery sheath during positioning. The catheter has a flexible proximal section and a substantially rigid distal section formed from a plurality of distal subsections. The proximal and distal sections having decreasing outer diameters starting from the proximal end and advancing towards the distal end. The distal subsection closest to the distal end providing an adjustable flow rate via multiple output ports defined radially therein while the distal end itself is closed off.

    摘要: Therapeutic devices, especially vaso-occlusive devices or embolic coils, are delivered by an apparatus that includes a pullwire having a tine or tines that have an offset orientation that engages a therapeutic device. The pullwire passes through an opening of a headpiece. When the pullwire moves in a relative proximal direction, the tine moves toward a straight-line orientation, and the therapeutic device is liberated from the tine and from the pullwire. At this state, the therapeutic device is ready for deployment at a desired intraluminal location.

    摘要: A valve for use in a shunt system to drain fluid from one part of a patient's body to another is provided. In an exemplary embodiment, the valve is operable at a threshold pressure that is selectively adjustable up to at least about 400 mm H2O at increments in the range of about 10 mm H2O to 40 mm H2O. The ability of the valve to operate at a high threshold pressure and to be adjusted at relatively small increments renders the valve particularly advantageous for use in younger hydrocephalus patients. In particular, the operating pressure of the valve can be gradually limited in small increments over a period of time to slowly force the patient's own resorption system to circulate cerebrospinal fluid. At high operating pressures of at least about 400 mm H2O shunt independence can be achieved thereby allowing the shunt to be successfully removed.

    摘要: A cranial bolt secured to a skull of a patient includes a threaded portion and a lumen portion. Threaded portion has an inner surface forming a central passageway which extends throughout the threaded portion. The inner surface includes a connector mating with the lumen portion. The threaded portion has an outer surface having a plurality of threads for engaging a hole formed in the patient's skull. The lumen portion includes a stem portion that enters the central passageway and engages the mating connector. A fluid tight seal is formed between the inner surface of the threaded portion and the stem portion. At least two lumens are disposed through the stem portion and the base portion. The lumens have a proximal end opening outside the skull and a distal end opening inside the skull. One embodiment includes sensor lumens diverging from the centerline and another allows lumen portion to rotate independent of threaded portion.

    摘要: A pressure sensing catheter having a pressure sensor and an antenna that is coupled to the pressure sensor, e.g., by a connector, are provided. The pressure sensor can be adapted to measure a pressure surrounding the catheter, and the antenna can be adapted to telemetrically communicate the measured pressure to an external device. In an exemplary embodiment, the antenna, pressure sensor, and/or connector are hermetically sealed, e.g., by the catheter and/or a coating, to prevent the antenna, pressure sensor, and connector from coming into contact with fluid, thereby allowing the catheter to be permanently implanted or otherwise used for long term use. Exemplary methods for manufacturing and using pressure sensing catheters are also provided.

    摘要: Devices and methods for regulating and directing bodily fluids from one region of a patient to another region are disclosed. In general, an apparatus is provided that can include an implantable shunt system and a system controller. The implantable shunt system can have an adjustable valve for regulating the flow of fluid, a sensor element for measuring a physiological characteristic of a patient, and an electromechanical valve actuator that can be adapted to adjust a resistance of the valve. The implantable shunt system can be in electrical communication with the system controller. The system controller can generally be adapted to receive a physiological characteristic of the patient and operate the electromechanical valve actuator to adjust a resistance of the valve. The apparatus can also include an external programming device that is in communication with the system controller.

    摘要: A dural graft is provided having improved stiffness characteristics relative to conventional dural substitutes. The dural graft can be formed from a collagen material having a stiffness between about 0.1 pounds per inch (lb./in.) and 0.25 lb./in. Relative to the collagen material forming conventional dural graft substitutes, the decreased stiffness of the collagen material of the present dural graft can provide the graft with a relatively improved or increased pliability. As a result of the increased pliability, the dural graft can sufficiently conform to a curvature of a tissue surface to which it is applied, such as the curved surface of a meningeal membrane. The reduced stiffness of the collagen material can also provide for a relatively improved or increased flexibility or elasticity of the dural graft. The increased flexibility of the dural graft minimizes tearing of the graft when handled or manipulated during an implantation procedure.

    摘要: A shunt valve assembly includes an electromechanical brake mechanism that locks a position of a pressure setting mechanism within a shunt valve assembly. The electromechanical brake can maintain the position of the pressure setting mechanism in the presence of a relatively strong magnetic field to maintain a set pressure differential within the shunt valve assembly. In certain cases, the shunt valve requires repositioning of the pressure setting mechanism within the shunt valve assembly to adjust a fluid flow rate through the shunt valve assembly. A clinician can activate an external controller to transmit a signal to the shunt valve assembly through magnetically coupled antennas between the controller and the shunt valve. The shunt valve assembly utilizes the signal to activate the braking mechanism and unlock the pressure setting mechanism. The clinician then operates the controller to non-invasively reposition the pressure setting mechanism and adjust the pressure at which the shunt valve opens.
