Abstract: An in vivo imaging device having an illumination system that creates a virtual source within a tissue region of a subject in a non-invasive manner. The illumination system transforms a maximum amount of illumination energy from a light source into a high contrast illumination pattern. The illumination pattern is projected onto the object plane in a manner that maximizes the depth to which clear images of sub-surface features can be obtained. The high intensity portion of the illumination pattern is directed onto the object plane outside the field of view of an image capturing device that detects the image. In this configuration, scattered light from within the tissue region interacts with the object being imaged. This illumination technique provides for a high contrast image of sub-surface phenomena such as vein structure, blood flow within veins, gland structure, etc.

Abstract: A catheter system (100) for placement within a treatment site (106) at a vessel wall (208A) or a heart valve includes an energy source (124), a balloon (104), an energy guide (122A), and a tissue identification system (142). The energy source (124) generates energy. The balloon (104) is positionable substantially adjacent to the treatment site (106). The balloon (104) has a balloon wall (130) that defines a balloon interior (146). The balloon (104) is configured to retain a balloon fluid (132) within the balloon interior (146). The energy guide (122A) is configured to receive energy from the energy source (124) and guide the energy into the balloon interior (146) so that plasma is formed in the balloon fluid (132) within the balloon interior (146). The tissue identification system (142) is configured to spectroscopically analyze tissue within the treatment site (106). A method for treating a treatment site (106) within or adjacent to a vessel wall (208A) or a heart valve can utilize any of the catheter systems (100) described herein.

Abstract: An inflatable portable seat is readily transported for use in a desired environment, with the seat including planar top and bottom walls and an arcuate forward wall. An inflation valve is arranged for inflation of the seat structure, wherein the seat structure is arranged for interfolding and transported in an associated container. A modification of the seat includes an elastomeric strap for mounting of the container when the seat is inflated for convenient storage of the container and may be further provided with a polymeric foam sleeve mounted about the container for removal from the container and support of a beverage container therewithin and mounted within a further elastomeric strap within a side wall of the seat structure when inflated.
