摘要： A transperineal biopsy system for use with a transrectal imaging probe configured to provide imaging in at least a sagittal plane. The transperineal biopsy system includes an access needle and a biopsy guide. The access needle includes a hub at a proximal end and a tubular structure extending distally from the hub. The biopsy guide includes a fastener releasably attachable to the transrectal imaging probe, a guide member extending from the fastener, and a platform coupled to the guide member and including a plurality of needle receiving openings in a stacked arrangement. Each of the plurality of needle receiving openings is sized and shaped to support the access needle at a different height relative to the transrectal imaging probe and configured to support the access needle within the sagittal plane when the biopsy guide is attached to the transrectal imaging probe.

摘要： A system for tracking an instrument includes two or more sensors (22) disposed along a length of an instrument and being spaced apart from adjacent sensors. An interpretation module (45) is configured to select and update an image slice from a three-dimensional image volume in accordance with positions of the two or more sensors. The three-dimensional image volume includes the positions two or more sensors with respect to a target in the volume. An image processing module (48) is configured to generate an overlay (80) indicating reference positions in the image slice. The reference positions include the positions of the two or more sensors and relative offsets from the image slice in a display to provide feedback for positioning and orienting the instrument.

摘要： An automatic biopsy gun is described, the gun comprising a body and a needle cantileverly extending from the body. The needle comprises a stylet provided with a collecting hollow to collect a tissue sample, and a cannula in which the stylet is slidingly housed so that the collecting hollow can come out of the cannula and go back in it with a guillotine effect. The gun further comprises a pushing member to push the cannula and a pushing member to push the stylet, both being movable in the body between a forward position and a rearward position in order to slide the stylet with respect to the cannula. Elastic countering means counter the pushing members which are loaded by driving means operable by the user. Advantageously, pushing members are guided by inner guides that are inside the gun body and the guide of the cannula is closer to the needle than the guide of the stylet.

摘要： A catheter treatment apparatus comprises an elongate tubular member and an expandable support. The expandable support comprises a radioactive substance to treat cancerous tissue and is configured to expand from a narrow profile for insertion to a wide profile to engage and treat tissue remaining after resection. The expandable support can be sized to fit within a volume of removed tissue to place the radioactive substance in proximity to the capsule and remaining tissue, to spare the capsule and proximate nerves and vessels to treat tissue in proximity to the capsule. The elongate tubular member may comprise a channel such as a lumen to pass a bodily fluid such as urine when the expandable support engages the tissue to treat the patient for a plurality of days. The treatment apparatus can be used to resect and diagnose tissue concurrently. Based on the diagnosis, targeted segmental treatment may be given.

摘要： Present invention solved the problem of complications occurred during transrectal prostate biopsy, mostly infectious and bleeding complications. Thus, the prostate biopsy needle according to the invention comprising a cannula (1), a pointed stylet (2), which is mounted slidably in the cannula (1), handles (3a, 3b) for the biopsy gun, which are located on the back side of the needle. An inner surface (4) of the cannula (1) and/or an outer surface (5) of the cannula (1) and/or a surface of the stylet (2) is coated with at least one active layer (6) comprising a biologically active agent, wherein the active layer (6) preferably forms a biodegradable structure enabling controlled release of the biologically active agent.

摘要： The present invention is directed to a method for calculating tumor detection probability of a biopsy plan and for generating a 3D biopsy plan that maximizes tumor detection probability. A capsule shaped volume is modeled to represent the volume that a biopsy core may sample. An optimization method is used to generate a 3D biopsy plan that maximizes probability of tumor detection for predefined biopsy core numbers and length. Risk of detecting insignificant tumors, also determined by size, and probability of a false negative result is automatically calculated. The present invention also includes a method to determine number and length of biopsy cores required for individual patients determined by the balance of the insignificant/significant probability of detection, prostate size and shape, based upon the previously explained 3D biopsy plan generation method.
