摘要:
A medical imaging system comprises a teleoperational assembly and a processing unit including one or more processors. The processing unit is configured for receiving a roll position indicator for an imaging instrument coupled to the teleoperational assembly. The imaging instrument has a view angle greater than 0° relative (e.g., 30 degrees) to an optical axis of the imaging instrument. The processing unit is further configured for obtaining first image data from the imaging instrument coupled to the teleoperational assembly at a first roll position and for obtaining subsequent image data from the imaging instrument coupled to the teleoperational assembly at a second roll position. The processing unit is further configured for coordinating a roll movement of the imaging instrument between the first and second roll positions with a transition between presentation of the first image data and the subsequent image data.

In accordance with exemplary embodiments of the present disclosure, device and method can be provided which can facilitate imaging of biological tissues, e.g., luminal organs in vivo, using optical techniques. The exemplary device can include different designs an features of one or more catheters, which can illuminate the tissues, and collect signals from the inside of the lumen. In another exemplary embodiment according to the present disclosure, a balloon-catheter can be provided with the flexible neck, which can absorb most of the bending. According to still another exemplary embodiments of the present disclosure, a balloon-catheter tethered capsule can be provided, and according a yet further exemplary embodiment, a structured balloon design can be provided with one or more protuberances, thus enabling imaging of the structures in close contact, e.g., without compressing of the tissue.

Exemplary apparatus for coupling to a probe and providing information regarding at least one structure can be provided. For example, the apparatus can include an electronics arrangement which is configured to obtain the information and transmit the information wirelessly, and a structural connection configuration which is structured and configured to be attached to the probe. The electronics arrangement can include a detector arrangement which is configured to detect at least one return radiation from at least one portion of at least one sample based on the predetermined patterns, and provide the data for the portion(s) based on the return radiation(s). In addition, a computer arrangement can be provided which is configured to generate the information with includes image data for the portion(s) as a function of the data and prior knowledge of the predetermined patterns.
摘要:
A gripping system for use in treating the sinus cavity is described. The system includes a handle for single handed operation that includes access to the sinus cavity and treatment by dilation of an anatomical passageway within the ear, nose or throat. The handle contains a guide catheter or seeker for proper placement of the system and further includes a balloon catheter cartridge for treatment of the cavity. The handle may further contain a guidewire cartridge to ensure proper access of the cavity or a stabilizing feature for incorporation of an endoscope.
摘要:
An endoscope assembly has a tip that includes at least one front-pointing camera and at least one front illuminator associated therewith, at least one side -pointing camera and at least one side illuminator associated therewith, a first front service channel with a first exit point, and a second front service channel with a second exit point where the first and the second service channel exit points are located in close proximity on the front distal end of the tip. Further, an interior volume of the tip is in a range of 2.75 cm 3 to 3.5 cm 3 , wherein each of the at least two viewing elements is configured to generate a field of view ranging from 120 to 180 degrees, a depth of field ranging from 3 to 100 mm, and a peripheral distortion of less than 80%.
