Abstract
The present invention relates to a surgical kit for use in a craniectomy procedure, the surgical kit comprising: a medical device to be implanted in a cranial bone of a patient, the medical device (10) including several transducers for emitting ultrasound waves for treatment of brain tissue, a surgical accessory (20) intended to be positioned on the cranial bone of the patient, the surgical accessory (20) including a body whose outer perimeter defines the dimensions of an opening that is to be made in the cranial bone of the patient in order to receive the medical device, characterized in that the surgical accessory (20) comprises a plurality of holes (201) formed in the body, the position of each hole (201) on the body coinciding with the position of the axis of symmetry of a respective transducer, such that the accessory is able to be positioned optimally through the joint use of a neuronavigation system.
Core Innovation
The invention relates to a surgical kit for use during a craniectomy procedure, where a medical device capable of being implant in a cranial bone of a patient is provided. The medical device includes a support structure and several transducers mounted on the support structure for the emission of ultrasound waves for treating a brain tissue.
The surgical kit further provides a surgical accessory capable of being positioned on the cranial bone of the patient. The surgical accessory includes a body dimensioned to approximate the dimensions of the support structure of the medical device, where the outer perimeter of the body defines dimensions of an opening capable of being made in the cranial bone to receive the medical device.
A plurality of holes is arranged in the body of the surgical accessory. The position of each hole coincides with the position of the axis of symmetry of a respective transducer on the support structure, and each hole defines a marker for the end of a neuronavigation system in order to facilitate optimal positioning of the opening to be made in the cranial bone.
The craniectomy kit concept also includes an operating principle that links the use of the accessory holes with a neuronavigation pointer or similar neuro-navigation display means to guide drilling and device implantation relative to a brain lesion location.
Claims Coverage
One independent claim defines the core coverage. It contains a medical ultrasound-emitting implant device combined with a cranial-bone surgical accessory that uses multiple holes aligned to transducer symmetry axes as neuronavigation markers for optimal opening placement.
Ultrasound implant device with support structure and transducers
A medical device capable of being implant in a cranial bone of a patient, the medical device including a support structure and several transducers mounted on the support structure for the emission of ultrasound waves for treating a brain tissue.
Cranial-bone surgical accessory defining an opening matching the device support structure
A surgical accessory capable of being positioned on the cranial bone of the patient, the surgical accessory including a body dimensioned to approximate the dimensions of the support structure of the medical device, the outer perimeter of the body defining dimensions of an opening capable of being made in the cranial bone of the patient in order to receive the medical device.
Holes aligned to transducer symmetry axes as neuronavigation end markers
The surgical accessory comprises a plurality of holes arranged in the body, the position of each hole on the body coinciding with the position of the axis of symmetry of a respective transducer on the support structure, each hole defining a marker for the end of a neuronavigation system in order to facilitate optimal positioning of the opening to be made in the cranial bone.
The independent claim coverage centers on coordinating an ultrasound-transducer cranial implant with a cranial-bone accessory whose opening matches the device support structure and whose multiple holes aligned to each transducer’s symmetry axis serve as neuronavigation markers to facilitate optimal opening positioning.
Stated Advantages
Facilitates optimal positioning of the opening to be made in the cranial bone.
Enables marker definition for the end of a neuronavigation system to support optimal positioning relative to the transducer axes.
Documented Applications
Use during a craniectomy procedure for implanting a brain therapeutic device that emits ultrasound waves for treating brain tissue.
