Design and evaluation of a low threshold, porous tip lead with a mannitol coated screw-in tip ("Sweet Tip").

A screw-in transvenous lead has been developed for permanent atrial or ventricular pacing that makes insertion of a fixed helix lead smoother and less complicated. The helix has a mannitol coating that protects the helix during insertion and dissolves in the blood stream allowing the fixation of the helix by screwing it into the endocardium. The Sweet Tip lead features a porous tip mesh electrode designed to improve pacing and sensing thresholds, and HP silicone insulation of previously demonstrated reliability.

Anaerobic bacterial endophthalmitis in the rabbit.

Anaerobic bacterial endophthalmitis was studied in rabbits following intravitreal injection of live Fusobacterium necrophorum. Clinical response, bacterial recovery, and histopathology were studied. An inoculum of approximately 50 organisms produced endophthalmitis in 59% of injected eyes, while 1000 or more organisms produced endophthalmitis in 100% of injected eyes. The course and severity of disease seemed to be independent of the concentration of bacteria above a minimal inoculum size. Affected eyes showed progressive endophthalmitis. Histopathologic changes corresponded to the clinical gradation of endophthalmitis, including progressive retinal necrosis.
