A biopsy marker introduction assembly is configured for introduction through a specimen retrieval recess into a probe cutter lumen of a handheld breast biopsy handle. Advancing the cutter causes an extending deployment rod to distally translate within an introducer tube of the introduction assembly, pushing a biopsy marker out of a distal end of the probe at a surgical biopsy site. Thereby, the surgeon is able to position the probe and effect deployment of the marker even if using the other hand to position an imaging device such as an ultrasonic transceiver.

An apparatus and method are provided for precisely isolating a target lesion in a patient's body tissue, resulting in a high likelihood of “clean” margins about the lesion when it is removed for diagnosis and/or therapy. This approach advantageously will often result in the ability to both diagnose and treat a malignant lesion with only a single percutaneous procedure, with no follow-up percutaneous or surgical procedure required, while minimizing the risk of migration of possibly cancerous cells from the lesion to surrounding tissue or the bloodstream. In particular, the apparatus comprises a biopsy instrument having a distal end adapted for entry into the patient's body, a longitudinal shaft, and a cutting element disposed along the shaft. The cutting element is actuatable between a radially retracted position and a radially extended position. Advantageously, the instrument is rotatable about its axis in the radially extended position to isolate a desired tissue specimen from surrounding tissue by defining a peripheral margin about the tissue specimen. Once the tissue specimen is isolated, it may be segmented by further manipulation of the cutting element, after which the tissue segments are preferably individually removed from the patient's body through a cannula or the like. Alternatively, the specimen may be encapsulated and removed as an intact piece.

The wire protector has a first end and a protector strip, the first end including a site wall and a connector wall, the site wall defining an insertion site therein, the site wall further comprising one or more prongs, the prongs facing the insertion site, the protector strip comprising one or more strip walls, such that when the backing layer is removed from the attachment layer, first end is positioned over the device insertion site, the protector strip is positioned over the exposed portion of the device, the protector device covers the exposed device portion. The wire protector stabilizes and protects needle localization wires used in breast biopsies, and can be used for other implanted devices. Also disclosed is a method for covering such exposed portion of such inserted device.

The invention is directed to an electrosurgical device having a shapeable elongate cutting electrode having a free distal end with an exposed length of at least 0.5 inch and secured by its proximal end to the distal end of a handle. The electrosurgical device is designed for use with a high frequency electrosurgical generator which has an output at a frequency of between about 1 MHz and about 10 MHz, preferably about 3 to about 8 MHz. Preferably, the output has an essentially sinusoidal waveform with little harmonic distortion. The methods provide for the enhanced cutting of a variety of tissue including muscular, connective, glandular and fatty tissue. The device is particularly suitable in performing a breast biopsy.

A molecular breast imaging (“MBI”} configured for combined MBI and ultrasound imaging or MBI-guided biopsy is provided. In one configuration, the MBI portion of the system includes two opposed gamma ray detectors, while in another configuration only one gamma ray detector is provided. In two detector configurations, a compression plate is provided to make contact with and apply light compression to the subject under examination. One of the gamma ray detectors is configured to be moveable with respect to the other detector such that the gamma ray detector can be moved away from the examination region, thereby allowing access to the breast for an ultrasound imaging system or a breast biopsy device.

A method and system for auto positioning a compression mechanism in a mammography imaging system is disclosed herewith. The method comprises: automatically elevating the compression mechanism upon detection of a breast biopsy device. The breast biopsy device can be detected upon connecting the same to the mammography system or can be detected upon noticing the same on the vicinity of the mammography system. The compression mechanism includes: breast compressor, breast holding paddles and paddle holders.

A marker delivery device, “adaptor”, for a MRI breast biopsy system is described and claimed. The marker adaptor for the MRI breast biopsy device provides the operator with the ability to easily mark after an MRI biopsy procedure through the biopsy sleeve. The flexible shaft marker snaps into the marking adaptor which creates the oval shape that mates with the inner surface of the sleeve. This locks the orientation of the sleeve and marker, with adaptor, together. The marker adaptor also contains a hard-stop which allows the user to place the biopsy marker in the correct location.

An apparatus for use with a biopsy device to position a needle of the biopsy device within breast tissue is described and claimed. The apparatus includes a cannula, an obturator; and an obturator actuation assembly, which is described as an “overshoot obturator”. The overshoot obturator is designed to give the physician the ability to set the z-lock to the targeted depth, then move the obturator forward, relative to the sleeve to cut additional tissue. This reduces the tissue force which can push the obturator out of the desired biopsy location.

The invention relates to a correction and verification method, system and device for a breast biopsy localization device and a readable storage medium, and belongs to the technical field of medical images. In the precision correction and verification process of the breast biopsy localization device, according to different processes of correction and verification, a needle holder of the breast biopsy localization device is driven to move; a needle tip of a puncture needle is moved to a designated position; a stereotactic localization image pair is collected and recognized; precision correctionand verification of the breast biopsy localization device are achieved by measuring the position of the needle tip and a preset position, so that the personal error caused by personnel operations in judgment and recognition is effectively reduced, and the efficiency of precision correction and verification of the breast biopsy localization device is improved.

Examples of the present disclosure describe systems and methods for the long-term, real-time active monitoring of a wireless implant. In aspects, a wireless biosensor may be implanted in a breast biopsy cavity. The biosensor may detect biochemical parameter data of the breast biopsy cavity and the human body. The biosensor may transmit the detected biochemical parameter data in real-time to a surveillance system wirelessly coupled to the biosensor. The surveillance system may then facilitate the evaluation of the biochemical parameter data. In examples, the evaluation may comprise detecting trends in a tumors microenvironment, monitoring the progress of a treatment, or adjusting a treatment to tailor a personalized treatment.
