Abstract: An occluder for sealing gaps between a medical device and adjacent body tissue includes an expandable body configured to fill the gaps between the medical device and the body tissue. The occluder includes a fastener at one end of the body and adapted to couple to a first end of the medical device, and an expandable disk at the other end of the body and adapted to couple to the medical device at a position spaced from the first end.

Abstract: Embodiments of the present disclosure are directed to delivery devices, methods, and systems for delivering an implant to a target site. In one embodiment, a delivery device includes a core member defining a proximal end and a distal end and an outer winding defining a proximal end and a distal end, wherein the outer winding surrounds and is coupled to the core member. The outer winding extends at least partially between the proximal end of the core member and the distal end of the core member, and the outer winding is configured for displacement within a delivery catheter. The delivery device further includes a coupling member at the distal end of the core member configured to releasably attach to an implant.

Abstract: A high pressure alkaline metal discharge lamp includes a ceramic arctube and a discharge-sustaining fill. The fill contains rare gas and alkali metal, the alkali metal being cesium, rubidium, potassium or mixtures thereof. The fill is mercury free and cadmium free. The alkali metal vapor pressure during operation is at least 2 atmospheres.

Abstract: A metal halide lamp (10) has a ceramic arctube (12) with an inside length L, an inside diameter D, and an aspect ratio L/D of between about 1.5 and about 2.0 containing a suitable fill. The lamp may have a power rating of 200 W or more and can be used with an existing ballast.
