BIOPSY DEVICES, SYSTEMS, AND METHODS FOR USE

摘要

Apparatus, systems, and methods are provided for performing a biopsy within a patient's lung using an access sheath or catheter including a distal portion sized for introduction into an airway of a lung. An ultrasound imaging device is deployable from the distal portion for imaging tissue adjacent the body lumen, and a needle or other biopsy may be advanced from the distal portion into surrounding tissue, e.g., to obtain a tissue sample.

主权项

1. A system for performing a procedure within a patient's lung, comprising:
an elongate tubular member comprising a proximal portion, a distal portion sized for introduction into a body lumen of a lung, and one or more lumens extending between the proximal and distal portions, thereby defining a longitudinal axis; an ultrasound imaging device deployable from the distal portion for imaging tissue adjacent the body lumen; an expandable member on the distal portion configured to expand within the body lumen to isolate a region of the body lumen beyond the distal portion; and a source of vacuum coupled to the proximal portion and communicating via a lumen of the tubular member with a port in the distal portion for aspirating fluid within region of the body lumen beyond the distal portion to collapse the body lumen around the imaging device.
