Abstract
Methods, systems, and devices for assisting or performing an image-guided prostate procedure are disclosed. A needle assembly includes a needle guide, a needle device, a position sensor and additional features. The position sensor allows for the tracking of the needle assembly. A method for performing image-guided prostate procedures includes pre-operative procedures and intra-operative procedures. The pre-operative procedures include imaging studies to model the prostate and identify targets. The pre-operative procedures models are used during a prostate procedure to track the target and the devices used for the procedure. A system for performing image-guided procedures includes the needle assembly and other components.
Core Innovation
The invention provides methods, systems, and devices for assisting or performing image-guided prostate procedures such as biopsies or focal therapy. A needle assembly includes a needle guide, a needle device, and a position sensor which allows tracking of the needle assembly. The needle guide may have one or more lumens for introducing needles or other instruments and may include features to warm or cool tissue or measure temperature.
A method is disclosed involving pre-operative procedures comprising volumetric imaging studies to model and segment the prostate and identify targets, and intra-operative procedures including inserting a probe, scanning the prostate, matching images from the scan to the pre-operative images, and superimposing targets on the live images. A system includes a computer element, a tracking device, an imaging device, and the needle assembly, facilitating real-time image guidance and targeting of lesions within the prostate.
Claims Coverage
The patent includes two independent claims comprising a needle guide device and a system for performing image-guided procedures, each with multiple inventive features.
Curved retaining mechanism for needle guide
The needle guide includes a housing with at least one channel for receiving a needle device and a curved retaining mechanism rotatable about the channel's longitudinal axis from a retaining position allowing axial translation and rotation of the needle to a released position that enables removal of the needle without sliding through the channel.
Integrated system for image-guided procedures
The system comprises a needle device and a needle guide having a housing, at least one channel with a curved retaining mechanism as above, and a tracking device enabling location tracking during the procedure.
These inventive features enable secure yet releasable retention of needles within a guide and facilitate image-guided procedures by integrating tracking and imaging components with needle devices.
Stated Advantages
Facilitates precise targeting and tracking of needles during prostate procedures using integrated position sensors.
Allows secure retention and easy release of needles without necessitating sliding, enhancing procedural flexibility.
Enables multimodal pre-operative planning and intra-operative image guidance by integrating volumetric imaging data and live ultrasound.
Supports multiple therapeutic and diagnostic instruments introduction through multiple lumens in the needle guide.
Documented Applications
Image-guided prostate biopsy procedures to accurately target lesions identified on volumetric imaging modalities such as MRI.
Image-guided prostate focal therapies including cryotherapy, laser ablation, radiofrequency ablation, irreversible electroporation, microwave therapy, and brachytherapy seed placement.
Transrectal needle interventions supported by tracked ultrasound probes and needle guides for biopsy or therapy delivery.
