A localization mechanism, or fixture, is used in conjunction with a breast coil for breast compression and for guiding a core biopsy instrument during prone biopsy procedures in both open and closed Magnetic Resonance Imaging (MRI) machines. The localization fixture includes a three-dimensional Cartesian positionable guide for supporting and orienting an MRI-compatible biopsy instrument, and in particular a sleeve, to a biopsy site of suspicious tissues or lesions. A depth stop enhances accurate insertion, and prevents over-insertion or inadvertent retraction of the sleeve. The sleeve receives a probe of the MRI-compatible biopsy instrument and may contain various features to enhance its imagability, to enhance vacuum and pressure assist therethrough, and marker deployment etc.

A method for performing Magnetic Resonance Imaging (MRI) guided core biopsies is tendered more accurate and efficient by precisely positioning a disengaged probe assembly with respect to a localization fixture attached to a breast coil platform. The precise position is defined by MRI stereotopic location of suspicious tissue with respect to a fiducial marker on the localization fixture. With the probe inserted, dual lumens in the probe assembly are used for drainage or insertion of fluids as well as inserting diagnostic and therapeutic tools. Core biopsies are performed by engaging a biopsy instrument handle containing a cutter, with the localization fixture providing support and position to the handle. Repeated MRI scans are facilitated by the ability to disengage the handle without risk of displacing the probe assembly from the biopsy site.

MRI biopsy apparatus incorporating a sleeve and multi-function obturator

A biopsy device which is compatible for use with a magnetic resonance imaging machine. The device includes a non-metallic elongated substantially tubular needle having a distal end, a proximal end, a longitudinal axis therebetween, and a port on the elongated needle for receiving a tissue sample. The device further includes a sharpened distal tip for insertion within tissue. The sharpened distal tip is attached to the distal end of the needle and at least partially comprises a material which will leave an artifact under magnetic resonance imaging.

A biopsy device which is compatible for use with a magnetic resonance imaging machine. The device includes a non-metallic elongated substantially tubular needle having a distal end for insertion within tissue, a proximal end, and a longitudinal axis therebetween. The needle includes right and left members on either side of the longitudinal axis, where the right and left members each have upper and lower ends including a series of alternating male and female portions. The male portions of the right member mate with the female portions of the left member, and the male portions of the left member mate with the female portions of the right member to securely attach the two members together. The device further includes a port on the elongated needle for receiving a tissue sample.
