Abstract:
A method and system for automated and semi-automated predictable, consistent, safe, effective, and lumen-specific and patient-specific cryospray treatment of airway tissue in which treatment duration is automatically set by the system following entry of patient information and treatment location information into the system by the user, and treatment spray is automatically stopped by the system when the automatically selected treatment duration has been achieved as determined by the system.
Abstract:
Components, e.g., background, cytoplasm, nucleus and nucleolus, of a biological specimen are identified using multi-wavelength analysis. Specimen components, such as nucleoli, are selected, and a determination is made whether cells having nucleoli are cancer cells or regular repair cells based on one or more physical characteristics of the identified component. The physical characteristics can be one or more of a shape, size, texture and gray value.
Abstract:
A ductal access device is provided for accessing a breast duct and collecting biological material from within the duct. The access device may include an elongated member having an outer diameter sized for positioning within the breast duct and an internal lumen for infusing a fluid into the breast duct and collecting fluid from the breast duct and adapted to slideably receive a ductal introducer. The introducer may extend beyond the distal tip of the catheter and serve to penetrate the ductal orifice.

Abstract:
A system and method for marking a tissue site are described. A marker is deployed into or near the tissue site, where the marker can be later located using an imaging device external to the patient's body. After withdrawing the internal imaging device, the location of the marker can be identified using an external imaging device. Optionally, a biopsy of the internal tissue site can be performed based on the location of the marker.
Abstract:
A ductal access device is provided for accessing a breast duct and collecting biological material from within the duct. The access device may include an elongated member having an outer diameter sized for positioning within the breast duct and an internal lumen for infusing a fluid into the breast duct and collecting fluid from the breast duct. The elongated member may include a central axis extending through the internal lumen and a different axis being parallel to the central axis defining an off-axis configuration. An elongated distal tip extends beyond the distal end of the internal lumen and along the different axis. The elongated distal tip has a closed distal end for navigating within the breast duct. The elongated distal tip may include an internal passageway that is sized to slidiably or removably receive an elongated introducer.
