A needle guide for an angled ultrasound probe having a port tower with a plurality of needle ports aligned with an angled ultrasonic imaging plane. The needle ports in a port tower are aligned at the offset angle of the angled ultrasound probe and can support and guide a needle at the offset angle. Adjustment of the port tower along the transducer axis of the angled ultrasound probe maintains the alignment of the needle ports relative to the ultrasonic imaging plane and provides adjustment to accommodate differently sized patients. A method is also provided to securely align a needle with an angled ultrasonic imaging plane with an angled ultrasound probe such that the needle can accurately transect the ultrasound imaging plane.

An instrument guide (104) for a probe head (702) of an ultrasound imaging probe (106) that includes a transducer array (114) with a plurality of transducer elements (116) and an image plane. The instrument guide includes a probe support region (122) having a long axis (202) and configured to receive the probe head. The instrument guide further includes a first guide bracket (212) extending from a first side of the support region in a direction of the long axis. The instrument guide further includes a second guide bracket (230) extending from a second side of the support region in a direction transverse to the long axis. The instrument guide further includes a first guide (128) disposed in the first guide bracket. The instrument guide further includes a second guide (126) disposed in the second guide bracket.

A device includes an ultrasound probe including an elongated neck insertable in a patient and rotatable around a first longitudinal axis, an ultrasound transducer, and an elongated body rotatable around a second longitudinal axis that is parallel to and offset from the first longitudinal axis. The elongated body is removably attached to a probe mounting structure. A shaft is attached to the probe mounting structure, where rotation of the shaft causes corresponding rotation of the probe mounting structure and the attached elongated body of the ultrasound probe. The shaft defines a longitudinal shaft channel in an interior portion and a longitudinal shaft groove extending from a surface of the shaft to the longitudinal shaft channel. A cable is insertable into the longitudinal shaft channel through the longitudinal shaft groove, and enters an internal channel of the ultrasound probe through the longitudinal shaft channel enabling electrical connection with the ultrasound transducer.

A system, method, and apparatus for guiding a needle into a target location of a patient's body are provided. The system includes a planned needle guide trajectory and a guide for removable attachment to a smartphone. The guide includes at least one needle guiding aperture extending substantially perpendicularly to a screen of the smartphone. The needle guiding aperture defines an actual needle guide trajectory. An inclinometer application is running on the smartphone. The inclinometer application indicates to a user conformance of the actual needle guide trajectory to the planned needle guide trajectory.

A drug delivery system comprising: a plurality of needles; a needle guide for guiding and holding the plurality of needles during insertion into a patient's spine; a syringe containing a drug which is to be delivered into the patient's spine; a port multiplier comprising an inlet port connectable to the syringe and a plurality of outlet ports; and a plurality of tubes for providing fluid connections between the outlet ports of the port multiplier and the plurality of needles.

Systems, methods, and devices are provided for assisting or performing guided interventional procedures using. The system uses pre-procedure scans of a patient's anatomy to identify targets and critical structures. A measurement device containing position indicating elements or fiducials is placed in a pre-existing or physician created conduit or lumen whose geometry is known from a scan. During a procedure, the pre-procedure scans may be registered to the patient using the position indicating elements or fiducials and the geometry of the conduit. This registration may be used in an intervention to guide instruments that can obtain diagnostic information or provide therapy to the identified targets. During the procedure, the position indicating elements may be used to dynamically compensate for motion to further improve accuracy.

An apparatus for controlling a needle guide includes a first lever, a second lever, a first cam and a second cam. The first cam is attached to and extends from the first lever to a housing under the needle guide. The second cam is attached to and extends from the second lever to the housing under the needle guide. At least one of the first cam and the second cam is configured to translate rotational movement from the first lever and the second lever to both linear and rotational movement of the needle guide via the housing.

The present disclosure relates to cannula systems for delivery of a therapeutic agent to parenchymal tissue of a target subject. In certain embodiments, the cannula system is for delivery of a therapeutic agent to parenchymal tissue in the spine of a target subject. In certain embodiments, the cannula system includes a cannula positioning guide (CPG) useful in the delivery of a therapeutic agent to a localized target tissue of a subject. The guide may be used in a surgical suite or during a surgical procedure.

A method is described for planning intracorporeal positioning of a puncture needle to be introduced percutaneously into a patient on the basis of a puncture plan, said method comprising the following steps: a) arranging a needle guide means in a spatially fixed manner on the patient; b) generating and storing a series of cross-sectional images, each containing spatially resolved image information of the patient and of the needle guide means attached in a spatially fixed manner to the patient in a first coordinate system, using an imaging diagnostic method; c) selecting and visually displaying at least one cross-sectional image or a numerically generated cross-sectional image from the series of stored cross-sectional images; d) superimposing a virtual, positionally variable linear trajectory on the basis of the selected cross-sectional image; e) positioning the virtual linear trajectory on the basis of the puncture plan to obtain a target linear trajectory, in which the virtual linear trajectory traverses the needle guide means; f) numerically determining spatial coordinates of two separate spatial points, or traverse points, within the first coordinate system, at which traverse points the target linear trajectory traverses the needle guide means; g) transforming the spatial coordinates relating to the needle guide means and to the traverse points to a second coordinate system; and h) visually displaying the needle guide means within the second coordinate system in such a manner that the traverse points are shown visibly marked on the needle guide means.

A needle having a first end, a second end, and a lumen extending within an interior of the needle, between the first end and the second end. A sleeve is engageable within an interior diameter or interior surface of the lumen. The sleeve includes a first end and a second end that are sized to reside within the first end of the lumen and the second end of the lumen, respectively. Ports extend between the first end and the second end of the sleeve. The ports have an inlet and an outlet sized to receive and route stimulator wires to areas within the epidural space of a spine.
