An anatomical sensing system-guided prostate procedure device that includes a housing having a proximal end and a distal end. The housing may be divided into a distal housing section, amid housing section, and a proximal housing section, wherein the distal housing section is configured for insertion into the anus and retention in the rectum of a subject. The device further includes an instrument convergence point disposed between the proximal end and the distal end, the convergence point configured to allow an instrument pass though the instrument convergence point at a variable angle; and an instrument angle orienting system at the proximal end of the housing, the angle orienting system directing an orientation of the variable angle about the convergence point. Methods of the using an anatomical sensing system-guided prostate procedure device and system including the same.

A biopsy needle set that includes an outer cannula and a core collector that slides therein and includes a cradle that has a trough-shaped open space formed between a keel and two rows of teeth rising from lateral ends of the keel. The cradle has an outer surface that conforms closely to the cannula's inside wall such that when the cradle partly extends distally from the cannula the outer surface of the cradle bears against the cannula's inside wall to thereby resist bending of the core collector's portion that extends distally from the cannula

A medical needle arrangement (100, 1000, 1400) is disclosed. The needle arrangement (100, 1000, 1400) comprises: a needle sheath (104, 002, 1402), and a needle (202, 1102, 1406) comprising: an elongated portion and a sealing member (204, 1003, 1403) being arranged to a front end of the elongated portion. The needle arrangement is adapted to bet set in: a closed position, in which the sealing member (204, 1003, 1403) is arranged to abut at least a portion of a front end surface of the needle sheath (104, 1002, 1402) thereby restricting intrusion of foreign matter in an area between the needle sheath and the needle, and an open position, in which a gap (1204, 1506) is formed between the sealing member (204, 1003, 1403) and the front end surface of the needle sheath (104, 1002, 1402). Embodiments include needle arrangement for injection, for aspiration, and for biopsy purposes.

An impact biopsy device is disclosed. The impact biopsy device may be configured to displace various cutting elements, such as an outer tubular member and cutting element and a cannula to sever a tissue sample from a patient. The impact biopsy device may comprise an actuation system configured to transfer displacement or force to the cutting elements by the impact of an element on another element.

Prostate biopsy systems are provided that include a 3D ultrasound probe support configured to receive an ultrasound probe for transperineal imaging. One or more template grids can have a plurality of apertures extending therethrough to receive and guide a biopsy needle along a trajectory associated with respective apertures when the template grid is fixed to the support and the biopsy system is positioned in the perineal area of a patient. Patient-specific template grids can also be developed and produced. This system enables fully transperineal prostate biopsy (i.e. both imaging and needle placement are perineal) and eliminates the need for an external racking device for image fusion as well as needle tracking. In addition, it reduces the infection risk associated to transrectal approach.

A transperineal biopsy guide including a guide member and a displacement member supported by the guide member. The guide member may be configured to operably couple with the transrectal probe and may include a distal end, a proximal end opposite the distal end, and a length extending along a longitudinal axis between the distal and proximal ends. The displacement member may be configured to support the access needle and displace the access needle along at least a portion of the length of the guide member between the distal and proximal ends. The access needle may extend into the subcutaneous tissue when the access needle is displaced to the distal end.

The invention relates to a holder device for holding a medical instrument, the device comprising:

a base that is to be carried by an apparatus comprising a medical imaging probe associated with the medical instrument; and

a carrier structure for carrying the medical instrument and movably mounted on the base so as to be capable of moving on the base between a first position and a second position.

The invention also relates to an installation including both such a device and a needle-guide.

A biopsy and therapy device comprising: a needling unit for holding and inserting a biopsy needle; an imaging module comprising an ultrasound probe and an actuator for moving the probe in a reciprocal action; a first arcuate slide; a second arcuate slide in sliding engagement with the first arcuate slide and a linkage to which the first arcuate slide is mounted; said linkage arranged to move the first and second arcuate slides within a vertical plane; said needling unit mounted to said arcuate slide wherein the first and second arcuate slides are mounted perpendicular to each other so as to rotate the needling unit about respective first and second principal axes.

Systems, methods, and devices are provided for assisting or performing guided interventional procedures using custom templates. The system uses pre-procedure scans of a patient's anatomy to identify targets and critical structures. A template is then manufactured containing guide elements. During a procedure, the template may be aligned to the patient and instruments passed though the guide elements and into various targets. The template may be aligned using one or more of, for example, a position sensing system or a live imaging modality to register the patient to the template. The system makes optional use of devices designed to immobilize or track an organ during therapy.

A method and system utilizes an imaging device that generates images of target tissue of a patient during a surgical procedure that acts on the target tissue imaged by the imaging device. The method and system enables visual detection of patient movement during the surgical procedure by marking at least one spatial attribute of one or more identifiable features of the target tissue illustrated in an image presented in a display window. Prior to acting on the target tissue, a visual indicator of the spatial attribute(s) is superimposed on one or more subsequent images captured by the imaging device and displayed to the operator. The operator can visually compare a position of the visual indicator to a position of the operator-identified feature in order to detect movement of the patient during the procedure. The system and methodology also facilitates realignment that corrects for detected patient movement.
