Various stabilizers for supporting a trocar and stylet are disclosed. In some implementations, a stabilizer may include a main portion through which a trocar and stylet may be inserted and supported, and a plurality of stabilizing portions to prevent movement of the stabilizer when the stabilizer is placed on a patient's body.

A bilateral humeral guide for intraosseous infusion includes a three-dimensional minor symmetric shell configured to fit on either shoulder of a patient, the shell being symmetric about a plane bisecting an alignment hole configured to aid positioning of the shell on the shoulder by aligning the alignment hole on acromion of the shoulder, and two insertion-site indication holes symmetrically positioned on two opposite sides of the plane, the insertion-site indication holes including a left and a right hole each configured to indicate insertion sites for intraosseous infusion through the shell to a target region of a left or right humerus of the patient when the shell is positioned on the shoulder corresponding to the respective humerus.

Devices for guiding an instrument into a body of a patient, at a targeted point of entry and along an insertion path at a targeted insertion angle, are described herein, such as a guide for an access needle in a PCNL procedure for accessing the kidney to remove kidney stones. The devices include base component aligned with a point of entry, and a guide assembly which cooperates with the base component to allow an instrument to be aligned and fixed at various circumferential and vertical angles. The devices and methods allow a medical professional to accurately and stably guide an instrument at a targeted point and angle and to a desired depth, while minimizing the exposure to radiation used to image the insertion path.

A small gauge surgical instrument is shown with advantages such as diminished “play” at the tip. A surgical instrument assembly is also shown with support along a length of the instrument that can be selected by the surgeon. Devices and method described provide adjustability of the instrument without protruding into a gripping surface of the instrument.

A needle guide system for use with an ultrasound probe, the system comprising a surface marking guide and a needle guide. The surface marking guide includes an attachment portion for attaching the marking guide to an ultrasound probe, and a surface contact portion fixed to the attachment portion and including one or more features for identifying to a user where to mark a surface when the ultrasound probe is held against the surface. The needle guide includes a base to support the needle guide on the surface, one or more features on the base for alignment with marks made on the surface, and a needle support mounted on the base and having a needle channel through which a needle can extend, the needle channel having a known position and orientation relative to the base. We also describe a needle guide for use with an ultrasound probe to guide a needle along a predetermined path relative to the ultrasound probe.

A robotic acoustic probe for application with an interventional device (60). The robotic acoustic probe employs an acoustic probe (20) including a imaging platform (21) having a device insertion port (22) defining a device insertion port entry (23) and device insertion port exit (24), and further including an acoustic transducer array (25) are disposed relative the device insertion port exit (24). The robotic acoustic probe further employs a robotic instrument guide (40) including a base (41) mounted to the imaging platform (21) relative to the device insertion port entry (23), and an end-effector (45) coupled to the base (41) and transitionable between a plurality of poses relative to a remote-center-of-motion (49). The end-effector (45) defines an interventional device axis (48) extending through the device insertion port (22), and the remote-center-of-motion (49) is located on the interventional device axis (48) adjacent the device insertion port exit (24).

An introducing device for locating a tissue region and deploying an electrode is shown and described. The introducing device may include an outer sheath. An inner sheath may be disposed within the outer sheath. The inner sheath may be configured to engage an implantable electrode. In an example, the inner sheath may comprise a stimulation probe having an uninsulated portion at or near a distal end of the delivery sheath. The outer sheath may be coupled to a power source or stimulation signal generating circuitry at a proximal end. A clinician may control application of the stimulation signal to a tissue region via the outer sheath.

Surgical devices and methods of using the surgical devices are disclosed. The surgical devices generally include a trocar, a cannula releasably mounted on the trocar, and a propulsion system operatively connected to the trocar. The cannula includes a hub, and has a central opening through which the trocar extends. The propulsion system is operable to drive the trocar axially in a forward direction away from a proximal end of the surgical device.

A trajectory guiding apparatus and one or more methods associated therewith for facilitating precision-guided alignment and implantation of a DBS therapy device in a patient. A base plate and base frame combination provides a platform for a dual-stage slider (DSS) assembly comprising a bottom stage slider (BSS) table and a top stage slider (TSS) table that each have suitably sized apertures or orifices therethrough for allowing the passage of and securely holding an instrumentation column (IC) assembly whose translational movement (i.e., sideways or forward and/or backward directions along a translational plane) and pivotal/rotational movement (i.e., around a perpendicular axis orthogonal to the translational plane and extending through a pivot or fulcrum) are independently controlled by respective slide actuators in order to properly align the IC assembly to a desired trajectory.

Disclosed herein is a humeral intraosseous landmarking apparatus having a tab including an acromion placement circle, a band including a lateral epicondyle placement circle, where the lateral epicondyle placement circle and the acromion placement circle are separated by a fixed landmarking distance, and an intraosseous needle ring configured to landmark a humeral head, the intraosseous needle ring having a proximal end coupled to the tab and a distal end coupled to the band.
