In one example, a method for performing a medical procedure includes receiving a command to initiate tissue sampling with a surgical instrument at a target location, retrieving a predefined dynamic trajectory for tissue sampling from a memory device, and moving the surgical instrument according to the predefined dynamic trajectory to sample tissue at the target location.

The present disclosure relates to a guide assembly. The guide assembly includes a guide having a body having a first set of marks and a joint including at least one through hole, the joint configured for sliding along the length of the body; and a first surgical device having a second set of marks, wherein the guide is coupled to the first surgical device and a longitudinal axis of the through hole is co-radial with a mark of the second set of marks when the joint is located at a mark of the first set of marks. Other guides are also disclosed.

A technique for accessing extra articular lesions or abnormalities or intra osseous lesions or abnormalities or bone marrow lesions or all has the step of positioning the localizing pinning member onto cartilage or subchondral bone to define a virtual pathway through the cartilage or subchondral bone towards or into or through the lesion or abnormality or a desired target to create the virtual pathway utilizing an intra articular localizing pinning member to determine a location of the lesion or abnormality wherein the utilization of the localizing pinning member includes the step to locate or stabilize or both and thereafter using the virtual pathway to create an entry access.

An adapter (20) comprising a pair of rails (46) extending upwardly from a lower surface (38) and longitudinally in a direction from a long end (30) toward a short end (32) and converging to be parallel with the pair of edges (34) to define a third opening between the pair of rails (46) above the lower surface (38) for receiving the cannula (22) and stylet (24) transversely to the lower surface (38). An awning (48) positioned longitudinally between the first end and the second end and extending between and connecting the pair of rails (46) to define a first opening (42). The lower surface (38) defining a recess (50) disposed adjacent the short end (32) and extending from a second opening (44) into the channel (40) for receiving the flange (28) of the trocar (26) and defining a groove (52) for guiding the cannula (22) and the stylet (24) into the first opening (42). An indicia (54) extends from an upper surface (36) next-adjacent to the short end (32) to identify the second end for receiving the trocar (26).

An automatic vessel access device based on real time volumetric ultrasound is provided. The automatic vessel access device comprises a probe configured to generate a VOI image of a candidate vessel in a real time volume ultrasound scan mode, a control device coupled to the probe, and at least one motor coupled to the control device. The control device comprises at least one processing module configured to determine at least one control parameter based on the VOI image, and a driver module coupled with the at least one processing module and configured to drive the at least one motor to automatically access the candidate vessel according to the at least one control parameter.

The invention relates to a system for planning the introduction of a needle in a patient's body, comprising: a needle guide (3) intended to be coupled to a needle (2); a navigation system configured for tracking the needle guide (3) with respect to a 3D medical image of the patient; a processor configured for determining a virtual position and orientation of the needle (2) with respect to the 3D image (1) using navigation data of the needle guide (3), for detecting at least one inserted needle (2′; 2a′, 2b′, 2c′) as a trace in the 3D medical image (1) and for computing a distance between the virtual needle (2) and the detected needle (2′; 2a′, 2b′, 2c′); a display coupled to the processor for displaying a representation of the virtual needle (2) and a representation of the computed distance between the virtual needle and the at least one detected needle (2′; 2a′, 2b′, 2c′).

The instant invention is comprised of radiographic grids and an adjustable needle guide to facilitate the placement of an introductory needle using a two-dimensional aiming using an imaging needle guide comprising a proximal grid including a body, a top side, a bottom side, one or more radiopaque rings, and a central aperture extending through the body from the top side to the bottom side, a distal grid including a body, a top side, a bottom side, one or more radiopaque rings, and a central aperture extending through the body from the top side to the bottom side, and a needle.

A medical device and a method for preparing a patient's body to receive a bodily implant are provided. The medical device includes a needle member configured to be inserted into a tissue layer. The needle member has a proximal end portion and a distal end portion. An adjustment member is coupled to the proximal end portion of the needle member. The adjustment member includes an adjustment screw and a nut for setting a predetermined depth of insertion of the needle member within the tissue layer. The adjustment member further includes an adjustment member support configured to provide a support to the adjustment screw and the nut. The adjustment member is configured to move between a first position and a second position with respect to the adjustment member support to limit insertion of the needle member within the tissue layer to the predetermined depth.

System and methods for channeling a path into bone include a trocar having a proximal end, distal end and a central channel disposed along a central axis of the trocar. The trocar includes a distal opening at the distal end of the trocar. The system includes a curved cannula sized to be received in the central channel, the curved cannula comprising a curved distal end configured to be extended outward from the distal opening to generate a curved path extending away from the trocar. The curved cannula has a central passageway having a diameter configured to allow a treatment device to be delivered through the central passageway to a location beyond the curved path.

Described here are methods and systems for the manipulation of ovarian tissues. The methods and systems may be used in the treatment of polycystic ovary syndrome (PCOS). The systems and methods may be useful in the treatment of infertility associated with PCOS.
