A tissue removal system includes an electrosurgical generator including an active electrode port and a return electrode port, an active electrode device configured to connect to the active electrode port, and a return tissue guard configured to connect to the return electrode port. Another tissue removal system includes an electrosurgical generator including an active electrode port and a return electrode port, an active electrode device configured to connect to the active electrode port, and a return specimen bag configured to connect to the return electrode port.

A device and a method, which is individual to a patient, treat malignant diseases by using selectively acting tumor-destructive mechanical pulses (TMI). The tumor-destructive pulse shapes are determined using physical cell properties, which are individual to each patient. The device is controlled in such that lethal pulse fields are applied in the tumor area.

A method for guiding resection of local tissue from a patient includes generating at least one image of the patient, automatically determining a plurality of surgical guidance cues indicating three-dimensional spatial properties associated with the local tissue, and generating a visualization of the surgical guidance cues relative to the surface. A system for generating surgical guidance cues for resection of a local tissue from a patient includes a location module for processing at least one image of the patient to determine three-dimensional spatial properties of the local tissue, and a surgical cue generator for generating the surgical guidance cues based upon the three-dimensional spatial properties. A patient-specific locator form for guiding resection of local tissue from a patient includes a locator form surface matching surface of the patient, and a plurality of features indicating a plurality of surgical guidance cues, respectively.

Markers and related systems and methods are provided for localizing lesions within a patient's body, e.g., within a breast. The marker includes one or more photosensitive diodes for transforming light pulses striking the marker into electrical energy, one or more antennas, and a switch coupled to the photodiodes and antennas such that the light pulses cause the switch to open and close and modulate radar signals reflected by the marker back to a source of the signals. The antenna(s) may include one or more wire elements extending from a housing, one or more antenna elements printed on a substrate, or one or more chip antennas. Optionally, the marker may include a processor coupled to the photodiodes for identifying signals in the light pulses or one or more coatings or filters to allow selective activation of the marker.

Described herein are devices for placement in surgically created soft tissue spaces, potential spaces, or cavities. The implantable devices generally include a bioabsorbable body having an open framework that facilitates attachment of tissue thereto in a manner that helps avoid post-surgical deformities. Methods for using the implantable devices in oncoplastic surgery are further described.

Systems and methods are described for performing navigation-assisted medical procedures such as biopsies, surgeries and pathology procedures by obtaining location information of an item of interest located within at least a portion of a subject; sensing position information of a moveable device; determining a relative position of the moveable device to the item of interest using the location information of the item of interest and the position information of the moveable device; and providing feedback based on the relative position of the moveable device to the item of interest that can be used to change the relative position of the moveable device to the item of interest.

A dilator configured for separating subcutaneous fat from glandular tissue includes a center section, a first end section extending from a first end of the center section, the first end section extending nonparallel to the center section, the first end section having a first diameter, and a second end section extending from a second end of the center section opposite the first end, the second end section extending nonparallel to the center section, the second end section having a second diameter different than the first diameter. A retractor includes a handle, a shaft extending from the handle, and a head located at a shaft end opposite the handle. The head includes a plurality of teeth, each tooth having a tooth end curving downwardly from a head outer surface, adjacent teeth spaced from one another by a tooth gap therebetween, the plurality of teeth having unequal tooth lengths.

A method for surgically removing a tumor from a woman's breast is provided. The method can include inserting an optical trocar having a working channel and a transparent tip through a skin incision, guiding the transparent tip of the trocar through breast tissue with visualization such that the transparent tip of the trocar is placed adjacent to the tumor, insufflating gas via the working channel of the trocar to create a cavity in an operative field next to the tumor, dissecting the tumor free with a surgical instrument inserted through the working channel and removing the tumor through the trocar.
