Abstract: Devices and methods for both growing and in situ observation of microbiological cultures. The devices utilize thin transparent surfaces which bound a thin chamber which holds a layer of agar or the like and the microbiological sample. The agar and sample can be deposited through a sealable opening into the container. The dimensions of the container are such that it can be placed in a microscope allow in situ viewing of the culture through top or bottom surfaces. The method according to the invention fosters improved culture growth in the thin chamber and allows in situ observation of the culture with a conventional microscope.

Abstract: A catheter for cardiac procedures includes a generally C-shaped distal end which roughly conforms to the shape of an aortic arch. The catheter is made of a flexible material and includes a distal portion having a proximal section connected to an intermediate section at approximately 135 degrees. The distal most section attached to the intermediate section is generally perpendicular to the intermediate section and consists of a double or reverse curve. The structure allows the catheter to be utilized to enter either left or right ostia without catheter exchange by rotation of the catheter around its axis.
