Abstract: An improved medical lead assembly and method of use is provided. The lead assembly includes a lead body, and a spring member positioned adjacent to the lead body. The spring member may be deployed a selectable amount to maintain the lead body in a fixed location within a patient's body. The spring member may be an expandable coil, a mesh structure that is similar to a stent, or any other similar device that may be positioned in a low-profile state during a lead implant procedure. After the lead is positioned at a target destination, the spring member may be deployed an amount that is selected based on the characteristics of the surrounding tissue, including vessel size. According to one aspect of the invention, the lead assembly may provide means for facilitating chronic lead extraction.

The first nominal size is less than the second nominal size. The inorganic particles are sinter bonded.

Abstract: An apparatus for the inhalation of a vaporized essential oil includes a container where the essential oil is adapted to be disposed. A conduit is exposed to ambient air at one end and is disposed in the container above the essential oil at a remaining end. A path is provided through which air can be drawn into the conduit, exit from the conduit and mix with a vaporized essential oil in the container, and then be inhaled. According to a first modification a detachable canister is attached to a base block. According to a second modification, a modified base block is adapted for use with existing types of pipes.
