Abstract

The present invention describes a minimally invasive system that includes an elongated instrument and a stylet slidably disposed within a lumen of the elongated instrument. The instrument includes: a flexible proximal portion fixedly coupled to the rigid distal portion; and a lumen extending from the proximal end to the distal end through the flexible proximal portion and the rigid distal portion and defining a longitudinal axis of the instrument. The stylet includes a flexible body fixedly coupled to the steerable portion and a sensor element extending through the flexible body. The stylet is movable within the instrument between a retracted state, in which the steerable portion is retracted into the instrument, and an extended configuration, in which the steerable portion is at least partially removed from the rigid distal side of the instrument. Partially extended.

Description

[0001] related application [0002] This patent application claims a U.S. provisional patent entitled "Devices, Systems, and Methods Using a Steerable Stylet and Flexible Needle," filed April 2, 2014 Priority and benefit as of the filing date of application 61 / 974113, the entire content of which is incorporated herein by reference. technical field [0003] The present disclosure relates to systems and methods for navigating patient anatomy for minimally invasive procedures, and more particularly to devices for obtaining targeted tissue biopsies using a low-profile, flexible, steerable stylet and needle assembly and methods. Background technique [0004] Minimally invasive medical techniques aim to reduce the amount of tissue damaged during medical procedures, thereby reducing patient recovery time, lessening patient discomfort, and reducing harmful side effects. Such minimally invasive techniques may be performed through natural orifices in the patient's anatomy or through...
