A tubular sleeve is provided for enabling a physician to impart a preselected shape in an implantable tubular device, such as a cardiac lead, a catheter, or some other tubular structure. The sleeve may be deformed by the surgeon before or at the time of implantation to customize the shape of the tubular device to the particular anatomical structures to be encountered by the device. To retain the deformation imparted by the physician, the sleeve may be composed of a heat-sensitive shape-memory material or an elastomeric material provided with a plastically deformable rib.

The present invention relates to a novel method for analyzing nucleic acid sequences based on real-time detection of DNA polymerase-catalyzed incorporation of each of the four nucleotide bases, supplied individually and serially in a microfluidic system, to a reaction cell containing a template system comprising a DNA fragment of unknown sequence and an oligonucleotide primer. Incorporation of a nucleotide base into the template system can be detected by any of a variety of methods including but not limited to fluorescence and chemiluminescence detection. Alternatively, microcalorimetic detection of the heat generated by the incorporation of a nucleotide into the extending template system using thermopile, thermistor and refractive index measurements can be used to detect extension reactions.

Techniques are disclosed for performing thermal history control in a thermal printer in which a single thermal print head prints sequentially on multiple color-forming layers in a single pass. Each pixel-printing interval may be divided into subintervals, which may be of unequal duration. Each sub-interval may be used to print a different color. The manner in which the input energy to be provided to each print head element is selected may be varied for each of the subintervals.

A light valve such as an active matrix LCD between crossed polarizers, utilizing, for instance, individual transistors to control each "pixel area" of the LCD and storage elements to store video signal data for each pixel, with optically shielded "dead spaces" between pixels to eliminate electric field cross-talk and non-information-bearing light bleed-through, is illuminated with a bright independent light source which creates a video image projected via specialized projection optics onto an internal or external screen without distortions, regardless of the angle of projection onto the screen. Use of heat sinks, IR reflective coatings, heat absorbing optics, optional fluid and a thermistor controlled pixel transistor bias voltage injection servo circuit stabilizes image performance, maintaining accurate color and contrast levels as the LCD changes temperature. In one embodiment of the invention, use of a multi-color LCD with a stepped cavity, producing different thicknesses of LCD for the different wavelengths that pass through it, allows a linear correspondence between the wavelengths passing through the LCD to produce true black, high contrast and CRT-like color rendition. A dichroic mirror arrangement is used to overlap differently colored pixels in the projected image. Use of striped mirrors duplicate pixels, where necessary, eliminating spaces between pixels, creating a continuous image with no apparent stripes or dots. A special venetian-blind type of screen is also disclosed and methods for using the system to view three-dimensional video are also explained.

An electrically operated scented wax holder that forms a receptacle for receiving unmelted blocks of wax which are heated to the melting point and thereafter maintained at a safe temperature by a temperature-regulated electrical heating element. The wax receptacle is removable mounted on a base section that houses a positive temperature coefficient (PTC) thermistor which has a transition temperature substantially higher than the melting point of the wax to insure that the wax is rapidly melted, but substantially below the temperature that would constitute a danger to a human who might touch the exterior surface of the warmer, or constitute a fire hazard. The heating element is preferably placed in thermal contact with a contact pad having high thermal conductivity that is in turn placed closely adjacent to the wax receptacle, thereby efficiently transferring heat from the electrically operated temperature regulated heating element to the wax in the receptacle.
