Abstract: A surgical instrument includes a cutting assembly, an outer tubing, and a flexible torque component. The cutting assembly extends from a first proximal end to a first distal end. The cutting assembly includes an outer cannula defining a cutting window and an inner cannula disposed within the outer cannula. The outer tubing extends from a proximal tubing end to a distal tubing end. The distal tubing end is coupled to the outer cannula. The outer tubing is configured to receive a torque at the proximal tubing end and transmit the torque to the outer cannula to rotate the outer cannula. The outer tubing includes a plurality of first wires and a plurality of second wires each including more than eight wires and less than twenty four wires. The flexible torque component is coupled to a third proximal end of the inner cannula to rotate the inner cannula.

Abstract: A steerable biopsy device comprises an outer sheath comprising a sheath body having a proximal sheath section and a distal sheath section. The outer sheath further comprises a distal sheath tip and a sheath lumen terminating at a distal port in the distal sheath tip. The biopsy device further comprises a biopsy needle integrated with the sheath body. The biopsy needle is slidably disposed in the sheath lumen. The biopsy needle comprises a needle shaft and a distal needle tip configured for being displaced between a stored position within the sheath lumen and a deployed position outside of the distal port of the distal sheath tip. The biopsy device further comprises an articulation control actuator configured for articulating the distal sheath section, and a needle actuator configured for distally advancing the distal needle tip from the stored position to the deployed position.

Abstract: A system and method for retaining a tissue specimen obtained via a collection tube is provided. Embodiments provide a system including a collection device removably and serially disposed between a collection tube and a suction tube so as to allow fluid communication therebetween via the collection device. The collection device includes a screen for retaining a tissue specimen drawn into the collection device by and towards the suction tube while allowing any fluid accompanying the tissue to be drawn through the collection device and into the suction tube. The system also includes one or more end caps for sealing the collection device such that the collection device may store and/or transport the retained tissue specimen in a preservation fluid. A system for identifying and organizing collection devices retaining tissue specimens from various anatomical regions is also provided.

Abstract: A medical instrument for surgery includes at least one frame and at least one jointed device. The jointed device includes at least one first joint member, or first link, adapted to connect to at least one portion of the frame and at least one second joint member, or second link. The first joint member is connected by a rotational joint to the second joint member. The medical instrument includes at least a pair of tendons, adapted to move the second joint member with respect to the first joint member. Each of the first joint member and the second joint member includes a main structural body made in a single piece with one or more convex contact surfaces. Each of the convex contact surfaces is a ruled surface formed by straight line portions all parallel to each other and substantially parallel to a joint movement axis.

Abstract: A method performed by a computing system comprises receiving a collected set of spatial information for a distal portion of an instrument at a plurality of locations within a set of anatomic passageways and receiving a set of position into for a reference portion of the instrument when the distal portion of the instrument is at each of the plurality of locations. The method also comprises determining a reference set of spatial information for the distal portion of the instrument based on the collected set of spatial information and the set of position information for the reference portion of the instrument and registering the reference set of spatial information with a set of anatomical model information.

Abstract: The present invention comprises methods and devices comprising a cutting element used to contact circumferentially and longitudinally the surface walls of the endocervical canal to provide for broad and complete contact of the intended surface with the device, resulting in attainment of a sufficient volume and comprehensive tissue sample for analysis as an endocervical curettage or screening pap smear. The device may provide for a reservoir for the obtained sample to be contained when removing from the cervical canal and vagina. The device may be comprised of a detachable means or be of a material that allows the user to cut the sampling head of the device for placement in collection means to maximize the amount of tissue or cells being sent to the laboratory for analysis.

Abstract: The present invention discloses methods and a device for performing cardiology and endovascular interventional operations via a radial artery or ulnar artery. The method includes: step 1, putting an artery sheath into a punctured artery, wherein the artery is a radial artery or ulnar artery; step 2, allowing a guiding catheter to penetrate into the artery sheath from outside the body and penetrate out of the artery sheath from the other end to be advanced to a left ventricle; step 3, advancing a myocardial biopsy forcep to the left ventricle endocardium through the guiding catheter to collect a piece of myocardium; step 4, withdrawing the myocardial biopsy forcep from the guiding catheter to be outside the body, and preserving the myocardium specimen; step 5, repeating the step 3 and the step 4 until collecting enough number of specimens; and step 6, withdrawing the guiding catheter from the artery sheath, pulling the artery sheath out of the artery, and performing compression dressing over the access site. When performing myocardial biopsy and other relevant operations, the method does not need to penetrate other blood vessels or pull the artery sheath out of the artery and exchange the artery sheath with other sheathless guiding catheter or catheter, thereby making the procedure more convenient and more effective, as well as reducing complications caused by stimuli to the puncture site.

Abstract: A biopsy tool includes an elongated flexible body, a sensor assembly, and a screw member. The sensor assembly is disposed within the elongated flexible body towards the distal end thereof. The sensor assembly includes a location sensor(s) configured to enable detection of a location of the sensor assembly. The screw member is coupled to the distal end of elongated flexible body, extends distally from the elongated flexible body, and is positioned distally of the sensor assembly. The screw member defines a helical configuration having a hollow interior and is configured for simultaneous rotation relative to tissue and advancement into tissue to obtain a tissue sample.
