  • Patent number: 11918338
    Abstract: A flexible catheter includes an elongated body, and a sensor. The elongated body has proximal and distal end portions and defines a working channel therethrough. The sensor is disposed in the distal end portion of the elongated body and is adapted for detecting the position of a distal end of the elongated body within the anatomy of a patient. The sensor is formed from a wire that forms a first layer of wraps about the distal end portion of the elongated body and that includes first and second leads that form a twisted pair proximal to the first layer of wraps. The twisted pair of the first and second leads extends to the proximal end portion of the elongated body.

  • Publication number: 20220142624
    Abstract: A biopsy tool includes an elongated flexible body defining a distal end and a distal biopsy member disposed at the distal end of the elongated flexible body. The biopsy member incorporates a sensor assembly configured to enable detection of a location of the sensor assembly within a patient's airways. The biopsy member has a tissue-receiving portion defining a window and including first and second longitudinally-extending faces disposed on either side of the window. The faces are angled inwardly and towards one another to define an acute interior angle therebetween. Each face defines a sharpened cutting edge. The sharpened cutting edges are disposed on either side of the window. The faces are positioned such that the sharpened cutting edges increasingly approximate one another in the proximal-to-distal direction and culminate at an apex point.

  • Patent number: 10695038
    Abstract: A biopsy assembly includes a catheter, a valve, a device having suction and pressure modes, and a loss of suction indicator. The catheter includes a proximal end, a distal end configured to capture a tissue sample, and defines a lumen therebetween. The valve defines a first port coupled to the device and a second port coupled to the proximal end of the catheter. When suction is applied to the first port, a suction path is defined from the distal end of the catheter through the lumen of the catheter and into the second port, such that the tissue sample is suctioned into the catheter. Upon loss of suction at the distal end, the pressure mode is used to define a pressure path from the first port to an open third port, expelling material therefrom. In the pressure mode, suction is maintained at the second port and catheter coupled thereto.

  • Publication number: 20160302778
    Abstract: A biopsy assembly includes a catheter, a valve, a device having suction and pressure modes, and a loss of suction indicator. The catheter includes a proximal end, a distal end configured to capture a tissue sample, and defines a lumen therebetween. The valve defines a first port coupled to the device and a second port coupled to the proximal end of the catheter. When suction is applied to the first port, a suction path is defined from the distal end of the catheter through the lumen of the catheter and into the second port, such that the tissue sample is suctioned into the catheter. Upon loss of suction at the distal end, the pressure mode is used to define a pressure path from the first port to an open third port, expelling material therefrom. In the pressure mode, suction is maintained at the second port and catheter coupled thereto.
