Abstract:
Systems and methods that facilitate visualization and identification of lumens of a multi-lumen brachytherapy device are disclosed. In one embodiment, visualization and identification can be attained by modifying a feature of at least one of the lumens relative to the other lumens. The feature may include a marking on the lumen, a diameter of the lumen or a composition of the lumen. In an additional embodiment, for brachytherapy devices in which multiple lumens are coupled to a distal end point such as a rigid connection member, visualization and identification of the lumens can be attained by modifying a feature of the rigid connection member. It will be readily appreciated that visualization and identification can be further enhanced through a combination of two or more of the techniques described herein.
Abstract:
An automated system for preparing a plurality of cytological specimens from a plurality of fluid samples in vials includes an apparatus for collecting a monolayer of cells from each sample and transferring the cells to a microscope slide for fixing, staining, and inspection. The system includes a first loading station for receiving the sample vials, a second loading station for receiving consumables such as filter membranes, a slide dispenser, and an unloading area for removing completed specimen slides. To maintain one-to-one correlation between the samples and specimens produced therefrom, the system includes a subsystem for identifying each sample and permanently marking each slide with corresponding indicia prior to transferring the specimen thereto.

Abstract:
The present invention relates to a method and system for classifying biological specimen. A number of objects of interest are identified in a biological specimen. The nuclear area and nuclear integrated optical density for each object of interest in the specimen are measured and used for generating a scatter plot. The specimen is classified as normal or suspicious based on the distribution of points within the scatter plot.
Abstract:
Sterilization devices and methods for deploying porous implants within the fallopian tubes are disclosed. The devices include a catheter component including an external electrode sheath containing at least two deployable implants and a positioning member. Sliding the external sheath proximally disposes the implants within the fallopian tubes, while sliding both the positioning member and external electrode sheath distally reloads a second implant into the external electrode sheath. The devices further includes a handle component, which houses a chassis, external electrode sheath carrier, reciprocating shaft, positioning member carrier and first and second engaging members. The reciprocating shaft may be operated by a motor to slide distally and proximally along a long axis. The reciprocating shaft, external electrode sheath and its carrier, upon selective actuation, move together proportionally to deploy and reload the implants to facilitate occlusion of the fallopian tubes and complete sterilization.
Abstract:
Methods and systems for scanning a cytological specimen carried by a slide. Movement or positioning of a motorized stage of an automated screening system may be controlled manually by a user such that the user controls movement, e.g., controlling speed, position, and/or timing, of the motorized stage along a first scan line to controllably scan a first portion of the specimen along the scan line. The user may then index the motorized stage from the first scan line to the next scan line and manually control movement of the stage along the second scan line to controllably scan another portion of the specimen. Stage indexing may also be automatic such that the user does not control or initiate indexing.
Abstract:
The invention relates to a cell fixative that can be used in the preparation of slides for investigation by microscopy techniques. In particular the present invention provides a cell fixative that contains a light curable mounting medium.
Abstract:
Sample vials and methods of processing the sample vials are provided. The sample vial comprises a vial container, a sample collection chamber within the vial container, a vial cap configured to be mated with the vial container to enclose the collection chamber, an aliquot chamber, which may be carried by the vial cap or the vial container, and a valve mechanism for selectively sealing and unsealing the aliquot chamber from the collection chamber. The method may comprise flowing an aliquot of the sample from the collection chamber while the sample within the collection chamber is isolated from an environment exterior to the vial, sealing the aliquot chamber from the collection chamber to isolate the aliquot sample from the remaining sample portion, and transferring at least some of the remaining sample portion from the collection chamber to a microscope slide while the aliquot chamber is sealed from the collection chamber. The method further comprises reserving the slide for cytological screening of the sample, and reserving the aliquot sample for deoxynucleic acid (DNA) testing.
Abstract:
An improved image segmentation algorithm is provided that identifies each object in an image. Pixels of the image are sorted based on a range of attribute values of the image. These pixels are then added to a labeling image one by one starting with an extreme point in the range of attribute values. Features are calculated for each object located and these features are matched with pre-defined acceptance criteria. If there is a match, the object is output to an output image. The steps of adding pixels to the image, evaluating the features of the resulting objects and outputting the objects are repeated until a stopping point is reached.
Abstract:
A biological specimen collection and transfer system, including a biological sample container configured for storing a biological fluid sample, a vacuum source, a specimen filter having an interior chamber and an opening in communication with the chamber, and a fluid level regulator configured to determine a fluid level in the biological sample container and to dispense a fluid into the container if the determined fluid level is less than a desired fluid level. The fluid level regulator includes a fluid level monitor, a fluid dispenser, and a controller in communication with the fluid level monitor and the fluid dispenser, wherein the fluid level monitor includes a sound source configured to emit sound towards a surface of the fluid sample, and a sound detector configured to measure sound reflected from the surface of the fluid sample, wherein the controller determines the fluid level based at least in part on a measurement of reflected sound emitted from the sound source.
