摘要： An expandable intravascular medical device comprises an arcuate spring configured to be expanded into contact with the inner surface of a blood vessel. Another medical device comprises an electrode support structure, e.g., a non-tubular arcuate structure or a cylindrical member, and a plurality of resilient spring loops laterally extending from the support structure. The contact created between the loops and a blood vessel is sufficient to anchor the medical device within the blood vessel. In another embodiment, the medical device comprises an elongated member and two resilient spring arms extending distally from the elongated member. The arms are configured to be laterally moved towards each other to place the medical device in a collapsed geometry, and configured to be laterally moved away from each into contact with an inner surface of a blood vessel to place the medical device an expanded geometry.

摘要： Methods and kits for delivering an electrode lead into the head of a patient are provided. A burr hole is formed within the cranium of the patient, and an electrode lead is threaded through the burr hole. The electrode lead is then placed in a pre-shaped two-dimensional geometry between the cranium and cortical brain tissue of the patient. An access anchor may be mounted into the burr hole to facilitate introduction and removal of the electrode lead and other devices. In some circumstances, it may be desirable to separate the dura mater overlying the cortical brain tissue from the cortical brain tissue to create a pocket in which the electrode lead may be manipulated. In this case, a tissue layer dissection device can be introduced through the burr hole, operated to separate the dura mater from the cranium, and then removed from the burr hole. In one embodiment, the dissection device comprises a balloon that can be inflated to separate the dura mater and cranium, and then deflated prior to removing the dissection device from the burr hole.

摘要： A medical lead and method of treating a patient are provided. The medical lead comprises an electrically insulative tubular membrane, a resilient spring element associated with the insulative membrane, and at least one electrode associated with the insulative membrane. The medical lead is configured to be collapsed into a compact form for percutaneous delivery into the patient, thereby obviating the need to perform an invasive surgical procedure on the patient. The body formed by these elements, when expanded, can be sized to fit within the epidural space of a patient. The patient can be treated by placing the medical lead into a collapsed state by applying a compressive force to the medical lead, percutaneously delivering the collapsed medical lead into the patient adjacent tissue to be treated, and placing the medical lead into an expanded state by releasing the compressive force. In one preferred method, the stimulation lead is used to stimulate tissue, such as spinal cord tissue.

摘要： An expandable intravascular medical device is provided. The medical device comprises an expandable tubular body that includes an integrated resilient support structure that forms a plurality of electrically conductive regions to which the lead(s) is coupled. The tubular body further includes at least one electrically insulative element disposed between the conductive regions. In one embodiment, the support structure is skeletal in nature, e.g., it can be formed of a mesh, braid, or coil. The conductive regions can be variously formed by the support structure. For example, the support structure may comprise electrically conductive sub-structures that form the conductive regions. In this case, the sub-structures may be mechanically linked together by the insulative element(s), or they can be directly linked together, and the insulative element(s) can take the form of insulative layer(s) disposed on one or more of the conductive sub-structures. As another example, the support structure can have a conductive core and insulative material disposed over portions of the conductive core. In this case, the exposed core portions form the conductive regions, and the unexposed core portions form the insulative element(s).
