An electrode assembly and construction method therefor for use in small high performance batteries suitable for implantable medical device applications. The electrode assembly comprises a stack of precisely aligned planar elements including alternately arranged positive and negative planar electrodes having a planar separator interposed between adjacent electrodes. Each electrode is preferably formed of a thin metal substrate carrying active material on front and rear faces. The peripheral edge of each electrode defines an active area and a tab extending therefrom. The front and rear faces of the active area each carries a layer of active material. The faces of the tab area are preferably bare. The positive electrode tabs are located at a first position along the peripheral edge whereas the negative tabs are located at a second position spaced from said first position. Each tab carries a clip to form a reinforcing strip adjacent each tab face.

A brachytherapy device for treating tissue within a cavity of a body. The device may include a first set of tubes configured to be inserted into the cavity through an opening at the surface of the body. Each of the tubes may have an external end and an interior channel beginning at the external end that is configured to receive radioactive material. The external ends of the tubes may be bundled together. The tubes may be of a length that causes the external ends to be near the opening in the surface of the body while the tubes are in the cavity. A seal may be configured to prevent fluid that originates from the cavity from entering into the external ends of the tubes while they are near the opening in the surface of the body. The seal may include a gasket that is pressed against the external ends of the tubes. The gasket may have openings that align with channels within the external ends of the tubes.

The present invention relates to a curing light having a detachable tip for spot curing of light sensitive composites. A series of tips having varying apertures is also envisioned. The present invention also relates to a curing light having a detachable tip for effecting partial curing of light sensitive composites. The advantage of the tip of the present invention, as compared to prior art tips, is that it is adapted to be fitted over the end of a curing light device without the need to remove any protective cover, focusing lens or similar structure that may be mislaid or lost. It also offers the added advantage of a simplified design without the necessity of having built-in complex optical properties normally served by the protective cover while, at the same time, the tip retains the advantages offered by prior art tips.

A stripline tapped-line filter is disclosed including a first substrate upon which a plurality of N hairpin resonators are disposed alternately on opposite surfaces of the first substrate. Each one of the hairpin resonators is in a parallel coupled relationship with an adjacent hairpin resonator disposed on an opposite surface of the first substrate. The first and last hairpin resonators each have an interconnected member disposed on the substrate for respectively coupling a signal into and out of the plurality of N hairpin resonators. Second and third substrates are included with each being respectively located adjacent to ones of the plurality of N hairpin resonators on opposite surfaces of the first substrate. First and second groundplanes are included with each respectively located adjacent the second and third substrates.

A very low reflection transition with tightly controlled variability between a rectangular coaxial transmission line and a microstrip transmission line. The microstrip ground plane is extended under the transition region to form the transition ground plane. The upper portion of the dielectric of the rectangular coaxial transmission line is removed at the transition region, together with the upper portion of the center conductor. The spacing between the transition center conductor and the ground plane is reduced in relation to the spacing between the rectangular coaxial line center conductor and outer conductive shield. A tuning cavity is formed in the transition ground plane beneath the transition center conductor.
