Abstract:
A system for treating tissue includes a first anchoring device including a first anchoring element at a distal end thereof for anchoring the first anchoring device in a first target portion of tissue extending about a periphery of a tissue defect to be treated and a first suture receiving feature at a proximal end thereof. The system also includes a second anchoring device including a second anchoring element at a distal end thereof for anchoring the second anchoring device in a second target portion of tissue about the periphery of the tissue defect and a second suture receiving feature at a proximal end thereof. Furthermore, the system includes a suture configured to be passed through the first and second suture receiving features such that a tension applied to the suture draws the first and second anchoring devices toward one another to close the tissue defect.
Abstract:

Abstract:
A method is provided for enhancing video images in a medical device. The method includes receiving a first image frame and a second image frame from one or more image sensors. The first image sub-blocks are generated by dividing the first image frame. At least one curve to the first image sub-blocks are associated based on one or more look-up tables. A target in at least one of the first image sub-blocks is identified. Second image sub-blocks are generated by dividing the second image frame. At least one curve is associated to the second image sub-blocks based on the one or more look-up tables. The target is identified in at least one of the second image sub-blocks. Histogram enhanced images of the target in the first image sub-blocks and the second image sub-blocks are generated. A video image stream is generated based on the histogram enhanced images of the target.
Abstract:
A medical device includes a shaft and a braided sheath. The braided sheath is coaxial with the shaft and at least extends along the shaft between a distal end of the shaft and a proximal end of the shaft. The braided sheath includes a braiding. The braiding includes a plurality of mechanical strands and at least one conductor configured to deliver energy to or convey signals to and from an electrical device positioned at or near the distal end of the shaft.
Abstract:
Systems and methods for color correcting images are described. An example method includes receiving, at a first and second time: first and second image data from an imaging device of a medical imaging system captured during a medical procedure; and a first and second value of an operating parameter of a light source of the medical imaging system, where a color of light emitted from the light source shifts based on values of the operating parameter. A first color shift is determined based on the first value, and a color correction function is applied to the first image data to compensate for the first color shift to generate first color corrected image data. A second color shift is determined based on the second value, and the color correction function is applied to the second image data to compensate for the second color shift to generate second color corrected image data.
Abstract:
A method of generating a color image using a monochromatic image sensor. The method includes sequentially illuminating a surface in a plurality of colors, one color at a time. The monochromatic image sensor captures a plurality of image frames of the surface based on the plurality of colors. The plurality of image frames are identified, and at least one feature in the target of the plurality of image frames is highlighted. Color intensities of the plurality of image frames are normalized. A color intensity map of the target for each of the plurality of image frames is generated. A correlation score is determined by comparing each color intensity map of the plurality of image frames. The color image is generated based on the correlation score.
Abstract:
A medical device, comprising a handle including a port, a shaft extending distally from the handle, wherein the shaft includes a channel extending along at least a portion of a length of the shaft, wherein the channel includes a longitudinal opening on a radially outer surface of the shaft, and a removable portion extending through the channel, wherein the removable portion includes a first lumen, and wherein the removable portion is configured to be separated from the handle and the shaft.
Abstract:
A portable computing device of a medical imaging system that is connectable to a controller includes: a medical device connector for connecting a medical device that includes an imaging device to the computing device, at least one memory storing instructions, and one or more processors including an image processor. Execution of the instructions by the processors cause the computing device to perform operations, including to determine a connection status of the computing device and the controller, operate the computing device in a first or second operating mode based on the connection status, and receive image signals from the imaging device. When the computing device is operating in the first operating mode, the image signals are processed, by the image processor, to generate image data. When the computing device is operating in the second operating mode, the image signals are provided to the controller for processing.
