Apparatus for automated opening of craniotomies for mammalian brain access

An automated craniotomy opening apparatus includes a drilling apparatus with a drilling tip, at least one drilling apparatus positioning device, a detection device, and a computer processor that automatically controls the drilling apparatus, the positioning device, and the detection device. A method for automated opening of craniotomies includes, under automatic control of a computer processor, drilling into a skull for a predetermined distance and determining when there is a conductance drop near the drilling tip that indicates skull breakthrough. If the conductance is not below a predetermined threshold, drilling continues iteratively manner until conductance is below the threshold. A craniotomy pattern may be predetermined and automatically drilled under control of the processor. A cranial window may be created by drilling along a path that interpolates between holes to form the circumference of the window. Determining conductance may include use of an impedance detection circuit.

20230017864 · 2023-01-19 ·

Systems and methods for sonicating a body within an organ of a patient include supplying ultrasound energy to the body in order to produce a liquified material, which can then be aspirated from the body via a catheter. Image guidance is used during aspiration of the liquified material.

Method and apparatus for securing a guide tube

A guide tube is used for guiding an instrument through a hole within tissue of a patient. The guide tube includes a cannula member defining a passage extending therethrough along an axis. The passage is operable to receive the instrument and guide the instrument through the hole within the tissue of the patient. The guide tube also includes an expansion member that is moveably coupled to the cannula member to selectively move radially between a retracted position and an expanded position relative to the axis of the cannula member. The expansion member is at least partially insertable into the hole when the expansion member is in the retracted position. The expansion member is operable to engage with a surface of the hole when the expansion member is in the expanded position.

PERCUTANEOUS INVASIVE INSTRUMENT GUIDE

An introducer guide includes a guiding assembly to guide insertion an instrument, such as a biopsy needle, through a selected insertion point on a patient's body and along a selected insertion path. An imaging system, such as a CT scanner, is used to visualize portions of the guiding assembly in relation to the patient's tissues as the insertion path is adjusted. The guiding assembly includes a semicircular arch connected with a base plate by sliding hinges with a center of curvature of the arch centered on the insertion point. A guide body is slidably connected with the arch. Rotation of the arch about the hinges adjusts a first angle of the insertion path. Motion of the guide body along the arch adjusts a second angle of the insertion path. Linkages, such as linear actuation cables, rotary cables, or pneumatic or hydraulic actuators, connect the arch and guide body with remote operators. A practitioner aligns the guide assembly with the insertion point and fixes the base to the patient's skin. The practitioner uses the remote operators to adjust the orientation of the insertion path while visualizing the insertion path using the imaging system. The length of the cables is selected to allow the practitioner to adjust the guiding assembly at a safe distance from ionizing radiation emitted by the imaging system.

Cranial access device

An access system having a communication component that interfaces with a first device and a second device, where the first device is located inside or on an entity and coupled to a biological organism of the entity, and where the second device is located outside the entity and a controller component that controls a function of the first device, employing the communication component, to provide treatment to the biological organism of the entity coupled to the first device based on a request received from the second device.

IMAGE-GUIDED SURGICAL SYSTEMS WITH QUANTITATIVE EVALUATION OF IN VIVO THERMAL TREATMENTS AND RELATED METHODS

Methods and systems that provide quantitative assessments of in vivo thermal treatments, such as ablations, during image-guided surgeries using a high-resolution pre-operative MRI image segmented with a shape constrained and deformable mesh representations of brain structures and generating 3-D visualizations of thermally treated volumes during the thermal treatment that can provide near real time visual and quantitative feedback to a clinician.

SYSTEMS AND METHODS FOR HIGH-BANDWIDTH MINIMALLY INVASIVE BRAIN-COMPUTER INTERFACES

Systems and methods for high-bandwidth, minimally invasive brain-computer interfaces (BCIs) are disclosed. The BCIs are configured for deployment and operation in conjunction with a comprehensive interventional electrophysiology procedural suite. Three primary methods of minimally invasive electrode array delivery are disclosed: (1) cortical surface delivery, (2) ventricular delivery, and (3) endovascular delivery. Additionally, systems and methods for interacting with such high-bandwidth electrode arrays are discussed, including real-time imaging, signal processing, and neural decoding. Systems and methods for architectures for accelerating the underlying computational processes (such as graphics processing units or tensor processing units) are also discussed. Multiple applications of BCIs are discussed, with emphasis on restoration, rehabilitation, and augmentation of neurologic function.

Cannula with illumination

A cannula with a proximally mounted camera and proximally mounted light sources. The lighting sources have beam axes directed distally, toward a workspace at the distal end of the cannula. The light sources are coupled with focusing lenses, to reduce the beam angle of the lighting sources and reduce glare within the cannula tube.
