A system for evaluating the evolution of a subject's bone structure, including an implantable medical device and a calculation module for computing a parameter representative of the bone structure. The implantable medical device has a distraction body and reflector(s). The distraction body distracts osteotomically separated bone section bodies and includes first/second blocks for implantation and attachment to first/second bone sections, the second bone section separated from the first bone section by an osteotomy, and an actuator for adjusting space between the first/second blocks, enabling distraction between the first/second bone sections. Each reflector reflects an electromagnetic signal and is embedded in a surrounding tissue when the distraction body is attached to the bone. The parameter is computed from the reflected signal, of an excitation signal including a frequency in the characteristic frequency range of each reflector, the reflected signal being representative of a dielectric constant of the surrounding tissue.

A medical imaging system comprising: a microwave antenna array comprising a transmitting antenna and a plurality of receiving antennae, wherein the transmitting antenna is configured to transmit microwave signals so as to illuminate a body part of a patient and the receiving antennae are configured to receive the microwave signals following scattering within the body part; a processor configured to process the scattered microwave signals and generate an output indicative of the internal structure of the body part to identify a target within the body part; and an ablation probe comprising an ablation needle movable relative to the microwave antenna array; wherein the receiving antennae are further configured to receive microwave signals scattered or emitted by the ablation needle and the processor is further configured to monitor a position of the ablation needle and to guide the ablation needle to the identified target within the body part which it can be used to perform an ablation procedure.

A surgery system includes a contactless control panel, an infrared camera, a computer and a display. The contactless control panel includes control areas which are arranged in a predetermined pattern and are coated with infrared reflective material to reflect infrared radiation. The infrared camera captures an infrared image of the control areas. The computer performs image recognition on the infrared image, determines, based on the predetermined pattern stored in advance and a result of the image recognition, which one of the control areas is masked, and generates a device control signal based on a function corresponding to the one of the control areas that is determined to be masked. The display device displays images based on the device control signal.

Disclosed herein is a method for multimodal imaging during a medical procedure using magnetic resonance imaging (MRI) and Raman optical imaging which involves administering an MRI imaging contrast agent that a chemical structure having charge-transfer electronic transitions. The tissue is imaged using and MRI device and the tissue is illuminated with excitation light that has spectral components that are approximately tuned close to one of the charge-transfer electronic transitions thereby producing enhanced Raman optical signals which are analyzed to produce Raman imaging data followed by registering the MRI and Raman imaging data. The present disclosure also provides a method for ionizing laser plumes through atmospheric pressure chemical ionization.

Systems and methods are described for functional brain mapping using neuronavigational equipment and additional features. For example, some implementations described combine novel cortical stimulator tools with stereotactic navigation for three-dimensional position tracking of the cortical stimulator tools. In some implementations, the systems and methods described herein can be used on an awake patient. In some implementations, the systems and methods described herein can be used on a patient that is asleep, via motor evoked potentials (MEPs), phase reversal, or electromyography (EMG) monitoring. Accordingly, in some cases sensory and language regions of the brain can be identified in addition to motor regions.

A surgical power drill system includes a housing unit, a driving unit, a tool holder, and a screw member. The driving unit is movably mounted in the housing unit and includes a motor and a motor shaft coupled to the motor. The driving unit is movable relative to the housing unit between a distal position, where the driving unit is distal from a front end of the housing unit, and a proximate position, where the driving unit is proximate to the front end of the housing unit. The tool holder is coupled to a first end portion of the motor shaft. The screw member is coupled to a second end portion of the motor shaft.

A medical device control handle has a first actuation assembly and a second actuation assembly, wherein each assembly has a shaft that is axially aligned but not rotationally coupled with the other shaft. The first actuation assembly includes a first actuation member and a clutch mechanism having a friction disk for generating frictional torque in rendering the first actuation member self-holding. The first actuation member has a cam portion adapted to impart translational motion and rotational motion for disengaging the clutch mechanism upon pivotation of the first actuation member, thus allowing rotation of the first shaft to manipulate a feature of the medical device, for example, deflection. The second actuation assembly includes a second actuation member and a translating member that is responsive to rotation of the second shaft so as to manipulate another feature of the medical device. The second actuation member is also self holding.

A system for assisting in performing an interventional procedure includes a first subsystem (1) and a second subsystem at different places, especially in different rooms. At a first place the first subsystem a) generates a first image of a subject (22) while an interventional device (12) is introduced into the subject and b) determines the position of the interventional device within the subject. At a second place the second subsystem a) generates a second image of the subject with the introduced interventional device and b) plans and/or monitors a treatment based on the second image and the already determined position of the interventional device, i.e. the second subsystem does not need to start a completely new position determination procedure, thereby reducing technical efforts. Moreover, the first and second images are generated by different imaging modalities which allows for, for instance, improved image guidance, planning and/or monitoring.

Devices, systems, and methods used to deploy a localization device into a target lesion are disclosed. The system includes a delivery device configurable in a ready-to-deploy state and a deployed state. When the delivery device is in the ready-to-deploy state, biased engagement members are engaged with proximal detents of a handle of the delivery device. When the delivery device is in the deployed state, the biased engagement members are engaged with distal detents. The delivery device is transitioned from the ready-to-deploy state to the deployed state by distal displacement of a plunger relative to the handle. The localization device is deployed from a cannula of the delivery device into the target lesion when the delivery device transitions from the ready-to-deploy state to the deployed state.

A system for use with a balloon disposed at a distal end of an intrabody probe includes an output device, configured to produce an output indicating whether the balloon is elongated, and a processor. The processor is configured to calculate, based on respective locations of multiple elements disposed on a surface of the balloon, multiple values, over an interval, of a parameter indicative of a radius of the balloon. The processor is further configured to modify a state of the output based on at least one of the values. Other embodiments are also described.
