    摘要: Medical devices having a barrier layer comprising an inorganic material. The medical device has a reservoir containing a therapeutic agent and the barrier layer is disposed over the reservoir. In one aspect, the barrier layer has one permeability to the therapeutic agent at one portion of the medical device and a different permeability at another portion of the medical device. In another aspect, the dosage amount of the therapeutic agent in the reservoir at one portion of the medical device is different from the dosage amount of the therapeutic agent in the reservoir at another portion of the medical device. In another aspect, a bioresorbable layer is disposed over the barrier layer at one or more portions of the medical device, wherein the bioresorbable layer comprises a bioresorbable material. Also, methods of coating a medical device are disclosed, in which a barrier layer over a medical device is formed using a lithographic etching process where a plurality of particles serve as an etch mask.

    摘要: Systems for nerve modulation and methods for making and using the same are disclosed. An example system for nerve modulation may include a first elongate element having a distal end and a proximal end and having a helical guide having a proximal end and a distal end. The system may also include a second elongate element having a distal end and a proximal end and having a nerve modulation element proximate the distal end. A sheath may be disposed about both the first and second elongate elements. Pulling proximally on the proximal end of the first elongate element may cause simultaneous radial and longitudinal displacement of the nerve modulation element.

    摘要: An implantable medical device includes a radiolucent member provided with an x-ray mirror that reflects incident x-ray radiation to enable visualization of the device. The x-ray mirror includes a multilayer nanolaminate having alternating layers of a first metal or ceramic layer deposited by atomic layer deposition having a first refractive index, and a second metal or ceramic layer deposited by atomic layer deposition having a second refractive index that is different from the first refractive index. The nanolaminate includes a total of at least four layers.

    摘要: A device for drying medium flow (8), in particular an air flow, includes a device housing (2), in which at least first and second drying agents (4, 6) are received. The first and second drying agents have a high moisture absorption capacity in the case of low and high moisture values of the medium flow (8), respectively. The amount of the respective drying agent (4, 6) can be selectively set depending on the actual moisture present in the medium flow (8).

    摘要: Medical devices that are visible by magnetic resonance imaging (MRI), and optionally, other imaging techniques, are described. In some embodiments, a medical device adapted for insertion into the body includes an elongated shaft and an electrically conductive path extending spirally about a portion of the shaft. The conductive path is capable of being connected to a current source. The medical device can further include one or more contrast agents (such as MRI contrast agents, radiopaque materials, and/or ultrasound visible materials), which can be arranged in a predetermined manner.
