A method and system for facilitating identification and marking of a target in a displayed Fluoroscopic Three-Dimensional Reconstruction (F3DR) of a body region of a patient. The system includes a display and a storage device storing instructions for receiving an initial selection of the target in the F3DR, fining the F3DR based on the initial selection of the target, displaying the fined F3DR on the display, and receiving a final selection of the target in the fined F3DR via a user selection. The system further includes at least one hardware processor configured to execute said instructions. The method and instructions may also include receiving a selection of a medical device in two two-dimensional fluoroscopic images, where the medical device is located in an area of the target, and initially fining the F3DR based on the selection of the medical device.

Embodiments of the invention provide a system and method for resecting a tissue mass. The system for resecting a tissue mass includes a first sensor for measuring a signal corresponding to the position and orientation of the tissue mass. The first sensor is dimensioned to fit inside of or next to the tissue mass. The system also includes a second sensor attached to a surgical instrument configured to measure the position and orientation of the surgical instrument. A controller is in communication with the first sensor and the second sensor, and the controller executes a stored program to calculate a distance between the first sensor and the second sensor. Accordingly, visual, auditory, haptic or other feedback is provided to the clinician to guide the surgical instrument to the surgical margin.

One embodiment provides a tightly targeted minimally invasive therapy (TTMIT) parathyroid tissue ablating instrument. A substance that cytotoxically ablates parathyroidal tissue during application in the parathyroidal tissue of therapeutically sufficient units of an electromagnetic energy having a frequency only ranging from ultraviolet to visible to near infrared. A substance delivery device is configured to introduce the substance into the parathyroidal tissue. An electromagnetic energy treatment device is configured to apply the therapeutically sufficient units of the electromagnetic energy within a thermal range that is non-cytotoxic to the parathyroidal tissue to the substance after the substance has been introduced by the substance delivery device. A sensor is configured to monitor activation of the substance as the therapeutically sufficient units of the electromagnetic energy are applied. The electromagnetic energy treatment device is further configured to modulate applying the therapeutically sufficient units of the electromagnetic energy once the substance has been activated.

A method for treating a site within a patient from which tissue has been removed includes providing at least one press-formed marker body formed of polysaccharide and a suitable binder; and placing the at least one of the press-formed marker body within the site where tissue has been removed so as to provide hemostasis therein.

A biopsy marker that can emit near infrared fluorescence for location of a biopsy site. The biopsy marker has a body formed from a polymer and a quantity of a near infrared fluorescent dye, such as indocyanine green, embedded in the polymer. A near infrared energy source is used to excite the near infrared fluorescent dye. A near infrared energy detector is used to detect any near infrared emissions from the biopsy marker. As a result, any and all biopsy markers within the field of view may be readily identified and located so that the tissue locations can be surgical removed if the tissue samples indicate a risk of cancerous tissue.

An ultrasound-detectable marker, ultrasound system, and methods for monitoring vascular flow and patency is disclosed. The ultrasound-detectable marker comprises one or more resorbable polymers, one or more non-resorbable polymers, one or more non-polymeric materials, or any combinations thereof. The ultrasound-detectable marker is adapted for placement underneath, adjacent to, or above one or more vessels at a postoperative site, such as a vascular anastomosis site. Further, the ultrasound imaging system includes certain user guiding software and/or health analysis software for use with the ultrasound-detectable marker.

An implantable magnetic marker comprising at least one piece of a large Barkhausen jump material (LBJ) containing at least one loop. The coiled marker is deployed to mark a tissue site in the body for subsequent surgery, and a magnetic detection system with a handheld probe excites the marker above or below the switching field required for bistable switching of the marker causing a harmonic response to be generated in a bistable or sub-bistable mode that allows the marker to be detected and localised.

Provided herein are systems, devices, assemblies, and methods for generating exciter signals, for example, to activate a remotely located tag. The systems, devices, assemblies, and methods find use in a variety of application including medical applications for the locating of a tag in a subject.

An intracorporeal marker delivery system includes a delivery device including a delivery cannula and a plunger. The delivery cannula has an inner lumen, a distal tip, and a discharge opening in communication with the inner lumen. A radiographically detectable marker having a fibrous-body and a radiographically detectable marker element coupled to the fibrous body is disposed within and pushable by the plunger through the inner lumen of the delivery cannula. An MRI detectable distal tip plug is disposed at least in part within a distal portion of the inner lumen distal to the radiographically detectable marker, and configured to partially occlude the discharge opening in the delivery cannula. An ultrasound detectable short term marker is interposed between the radiographically detectable marker and the MRI detectable distal tip plug in the inner lumen of the delivery cannula.

An apparatus for use with a minimally invasive medical procedure into human breast tissue includes a cannula and an obturator. The cannula includes an open distal end, a lateral opening proximate to the open distal end, and a longitudinal lumen communicating with the lateral opening and the open distal end. The lumen has a non-circular cross-section. The obturator is sized for insertion into the cannula. The obturator has a distal end extending from the open distal end of the cannula when the obturator is inserted fully into the cannula. The obturator has a recess proximate of the distal end of the obturator. The recess is positioned along a portion of the length of the obturator to align with the lateral opening of the cannula when the obturator is inserted fully into the cannula.
