Image guided biopsy needle

A medical device comprising:

• a handle;
• an elongate member extending from the handle, the elongate member defining an elongate member lumen;
• a biopsy needle extending through the elongate member lumen, the biopsy needle defining a biopsy needle lumen;
• an imaging device extending through the biopsy needle lumen, the imaging device movable between a first position within the biopsy needle lumen and a second position within the biopsy needle lumen, wherein the imaging device is at a distal tip of the biopsy needle and the elongate member in the second position, the imaging device including a complementary metal-oxide semiconductor (CMOS) sensor that faces the biopsy needle distal tip.

A method of acquiring a sample from a target site with a device having an elongate member that defines an elongate member lumen, a biopsy needle extendable within the elongate member lumen, and an imaging device extendable within the biopsy needle, the method comprising:

• extending the biopsy needle and the imaging device to a distal tip of the elongate member;
• using the imaging device to navigate the device to the target site;
• retracting the biopsy needle and the imaging device from the distal tip past an elongate opening of the elongate member lumen;
• activating a biopsy needle deployment feature from a first configuration into a second configuration at the elongate opening, the biopsy needle deployment feature forming a deployment ramp in the second configuration;
• advancing the biopsy needle and the imaging device along the deployment ramp and into the target site;
• retracting the imaging device from the biopsy needle;
• removing the sample from the target site;
• and
• retracting the biopsy needle from the target site and into the elongate member lumen.
