A system and method for controlling the insertion of a medical tool, such as a needle, into a subject's body based on measurements of an interaction parameter associated with the interaction between the tool and a bodily tissue, such as the forces exerted on the tool during insertion. The system comprises an insertion device, at least one sensor configured to measure the interaction parameter and at least one processor configured to receive sensor measurements, detect one or more predefined patterns in the sensor measurements and control an operation of at least one of the insertion device and an imaging device, upon detecting the predefined patterns. The processor may be configured to compare the actual correlation between the sensor measurements and an insertion parameter, such as insertion depth, with an expected correlation, and determine if the medical tool is following its pre-planned trajectory based on the result of that comparison.

The present disclosure relates to an apparatus for facilitating medical imaging of a subject. The apparatus comprises a medical imaging device receiver configured to receive a medical imaging device, at least one auxiliary equipment receiver configured to receive an auxiliary equipment for placement at a target portion of the subject, and a sound wave manipulation module arranged to direct transmission of sound waves between the medical imaging device and the subject, wherein an image of the target portion is formed by the medical imaging device for guiding placement of the auxiliary equipment. In particular, the medical imaging device is an ultrasound probe, the auxiliary equipment is a needle, catheter or endoscope, while the sound wave manipulation module comprises a sound wave deflection surface arranged to alter a direction of transmission of at least part of the sound waves. The present disclosure also relates to a method of deploying the apparatus.

A cannula for transferring a substance to and/or from a patient includes a rigid, tubular support sleeve, an inner sleeve, a transfer tube, and a conformal polymeric sleeve. The support sleeve defines a support sleeve lumen extending from a first opening at a proximal end of the support sleeve to a second opening at a distal end of the support sleeve. The support sleeve includes a rigid, MRI-compatible material. The inner sleeve is disposed in the support sleeve lumen and extends beyond the distal end of the support sleeve to a distal end of the inner sleeve. The inner sleeve defines an inner sleeve lumen. The transfer tube is disposed in the inner sleeve lumen and extends to or beyond the distal end of the inner sleeve to a distal end of the transfer tube. The transfer tube defines a transfer tube lumen terminating at an opening at the distal end of the transfer tube. The conformal polymeric sleeve surrounds at least a portion of the support sleeve and at least a portion of the inner sleeve. The conformal polymeric sleeve includes a transitional section extending from the distal end of the support sleeve and over the inner sleeve in a direction toward the distal end of the inner sleeve. The transitional section tapers inwardly in the direction toward the distal end of the inner sleeve.

Devices, methods, and systems are provided for placing an implant into a patient and removing it therefrom.

Disclosed are ultrasound devices and methods for use in guiding a subdermal probe during a medical procedure. A device can be utilized to guide a probe through the probe guide to a subdermal site. In addition, a device can include a detector in communication with a processor. The detector can recognize the location of a target associated with the probe. The processor can utilize the data from the detector and create an image of a virtual probe that can accurately portray the location of the actual probe on a sonogram of a subdermal area. In addition, disclosed systems can include a set of correlation factors in the processor instructions. As such, the virtual probe image can be correlated with the location of the actual probe.

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.

A device and system for and methods of using an ultrasound probe housing containing ultrasound probes configured to produce images inside the body of a patient for procedures requiring needle or probe insertion. The ultrasound probe housing can be configured with a guide channel cut-out or aperture between the ambient side and body side of a patient. A needle guide assembly may be pivotally connect internal to the guide channel cut-out or aperture of the ultrasound probe housing at a pivot point such that during use the needle enters the patient through the needle guide assembly within the ultrasonic probe housing so that the needle can be visualized by the ultrasonic probes in real time. The ultrasound probe housing may also provide an adhesion or suction quality to the body side of the device to facilitate aspects of the invention.

A system and method are provided for a guide system for guiding an interventional medical instrument toward a region of interest (ROI) along a predetermined trajectory path. The guide system comprises a base, an adjustment ring, and a plurality of guide blocks. The adjustment ring is configured to be selectively fixed in one of a plurality of rotational orientations with respect to the base. The plurality of guide blocks are each configured to be selectively fixed in one of a plurality of rotational orientations with respect to the adjustment ring and each include a guide hole. Each of the plurality of guide blocks include at least one of differing angles of trajectory or differing locations of the guide hole from others of the plurality of guide blocks to provide a selectable, predetermined location of the guide hole and angle of trajectory.
