  • Patent number: 9050447
    Abstract: A clamp for clamping flexible tubing is disclosed. The clamp includes a body having a first portion, a second portion, a first passage through the first portion, and a second passage through the second portion. The first passage is configured to compress a first length of the flexible tubing when the flexible tubing is displaced laterally into the first passage. The second passage is configured to compress a second length of the flexible tubing that does not overlap the first length when the flexible tubing is displaced laterally into the second passage.

  • Patent number: 8016790
    Abstract: An infusion status indicator disposed in the medical infusion line includes a housing with an opening through which the status of the infusion may be determined. A flexible membrane is located at the opening to indicate the status of fluid in the cavity. A recessed flexible membrane indicates insufficient flow of medical fluid into the cavity from the fluid supply, a level flexible membrane indicates correct flow of fluid through the indicator, and a concave flexible membrane indicates an insufficient flow of medical fluid out of the cavity, possibly indicating an occlusion of the fluid line downstream of the indicator. Check valves may be included upstream and downstream of the cavity so that a bolus of fluid may be forced out of the cavity to the patient by pressing the flexible membrane into the cavity.

  • Publication number: 20070201025
    Abstract: An apparatus and method are provided to verify the composition of a medical fluid in a fluid container. The verification is performed at a centralized location, where light is transmitted through the fluid and detected by a sensor that generates signals representative of the spectral data of the actual composition of the fluid. These signals are compared with the spectral data of an expected composition of the fluid. Based on the comparison, a label is generated that identifies the composition of the fluid and is affixed to the fluid container. The fluid container, with the verified fluid, is distributed to the point of care.

  • Publication number: 20070195308
    Abstract: In order to determine, rapidly and without the delay required by conventional tissue preparation techniques for pathological examination (freezing, sectioning, staining, etc.), whether, an excision, which may be a biopsy sample, is representative of the morphology of interest of whether an excisional biopsy in which the tissue taken completely removes the abnormality is, in either case, the tissue which is desired to be excisioned, the tissue specimen (18) in encapsulated, preferably as part of the biopsy procedure. The encapsulated tissue is contained in an optically transparent cassette (34). The cassette (34) or an endcap (38) enclosing the cassette is marked with a fiducial (40) indicating and corresponding to the location of the excision on the patient's body.

  • Publication number: 20070191942
    Abstract: A coating for an orbital implant where the coating has an anterior portion having a different, longer term bioabsorbability than a posterior portion. This allows the implant to have a smooth surface for insertion and to provide reduced irritation to neighboring tissues, to help prevent exposure of the porous core of the implant, and to provide a stable anchorment for extraocular muscles, but which also encourages rapid fibrovascular ingrowth. The coating is marked with a visual indicator to facilitate proper orientation. Shell materials are further selected to allow for sterile packaging, the securing of therapeutic agents thereon, and to provide adequately strong securing of the coating to the core. Apertures are formed through the coating to enhance fluid flow to and from the core, and to provide exposure of the surface of the core to extraocular muscles, and for sutures. The apertures are sized and shaped to reduce irritating surface contact with orbital tissues.

  • Publication number: 20050261717
    Abstract: The present invention relates to an optical obturator which includes a sleeve having a longitudinal bore between a proximal end and a distal end. The longitudinal bore of the sleeve is configured to receive at least a portion of an endoscope or like image transferring system. An image passing member, such as an optical window is positioned at the distal end of the sleeve and is provided to permit optical images to pass into the longitudinal bore of the sleeve and to permit illumination light to pass to the surgical site. An automatically retracting blade is positioned distal to the image passing member to facilitate penetration of body tissue.

  • Publication number: 20050157386
    Abstract: A tray or holder for tissue specimens, especially of excised tissue, such as biopsied specimens, is used with a confocal imaging system, especially a laser scanning confocal microscope system. The tray may be disposable after imaging of the specimen carried therein or may archive the specimen. A window supports the specimen. Clamps mounted inside the tray restrain the tissue. A compliant bag is mounted outside the tray on one side of a window of the tray on which the specimen is disposed. During imaging the specimen is immersed in a liquid contained in the tray having an index of refraction which closely matches the index of refraction of the tissue. The bag also contains an index matching liquid preferably having the same index as the liquid in the tray. A stabilizing plate is attached to a surface of the bag which faces the window.

  • Publication number: 20050099624
    Abstract: An apparatus and method are provided to verify the composition of a medical fluid in a fluid infusion channel by comparison with clinician-entered input. Light is transmitted through the channel and detected by a sensor that generates signals representative of the spectral data of the light detected. A processor compares the spectral data of the light detected to the spectral data associated with the expected contents of the channel to verify that the correct fluid is being infused.
