Abstract
This disclosure concerns systems and methods for tissue sampling using ultrasound guidance. Systems according to the various embodiments of the disclosure include a needle, for instance a biopsy needle, disposed coaxially about small gauge ultrasound probe. These systems are useful in a variety of procedures including pulmonary nodule sampling.
Claims20
A system, comprising:
- a biopsy needle having a gauge between 15 and 25;
- and
- an ultrasound probe slidably disposed within a lumen of the biopsy needle.
A method of treating a patient, comprising the steps of:
- inserting a biopsy needle and ultrasound probe through a bronchoscope into a bronchial tube of a patient, wherein the ultrasound probe is slidably disposed within a lumen of the biopsy needle;
- advancing the ultrasound probe and the biopsy needle to a site where a biopsy is desired;
- retracting the ultrasound probe into the biopsy needle, thereby creating a space into which a tissue sample can fit within the biopsy needle, and
- actuating the biopsy needle, thereby acquiring a tissue sample in the space.
1 more element
A system, comprising:
- a bronchoscope having a working channel;
- a biopsy needle slidably disposable within the working channel;
- and
- an ultrasound probe slidably disposable in a lumen of the biopsy needle.
