TISSUE ABLATION DEVICE WITH EXPANDABLE ELEMENT FOR DEVICE ARTICULATION
Aspects of the present disclosure include an inflatable balloon or other expandable element to articulate a working end of a tissue ablation probe in tissue ablation systems, devices, and methods.
Various systems, devices, and methods for tissue penetration are disclosed. The system includes an ablation element that penetrates the tissue and a radiofrequency generator that delivers energy to the ablation element. The radiofrequency generator may have two modes: a cutting or insertion mode and an ablation or coagulation mode. The cutting or insertion mode is used to cut or penetrate the tissue by providing a voltage or power modulation that acts to cut or soften tissue contacted by the ablation element. The ablation or coagulation mode is used to ablate or coagulate the tissue.
A real-time, intra-uterine operating field image is displayed to an operator. A processor identifies anatomical features and marks anatomical boundaries on the image with the aid of a trained classifier model. Labels for the identified anatomical features and the anatomical boundaries are displayed on the image. The trained classifier model is trained based on a set of prior surgical field images that have anatomical features and anatomical boundaries therein identified and marked, respectively, by previous operators. The trained classifier model is typically a convolutional deep neural network. The operator is allowed to modify the anatomical feature labels and anatomical boundaries, as well as update the set of training images with the modified image. The labeling of the anatomical features and establishment of the anatomical features facilitate performing treatments in the uterus, such as the ablation of uterine fibroids.

In an embodiment, the axial passage is configured for removably receiving the ultrasound imaging insert having an ultrasound array disposed on a distal portion.

A method and apparatus for medical imaging is described. The apparatus applies specifically to accessing and targeting tissue in a small cavity or tightly enclosed space. The medical imaging apparatus or device uses ultrasound waves with elements that act as both a transmitter and receiver in order to image body tissues. The ultrasound is an array or plurality of arrays that may be arranged on the tip on a probe or catheter for insertion into a patient's body.
Needle deployment and imaging system includes a sheath, an imaging core, and interventional core. The imaging core and interventional core are received in first and second axial passages in the sheath and at least one of said cores will be removable and replaceable within the sheath. The imaging core may be extended from the sheath or be sealed within the first axial passage of the sheath. The interventional core will typically be advanced laterally or axially from a location near the distal end of the sheath.

Methods and devices for both imaging and treating uterine fibroid tumors in one real-time system are provided. One minimally invasive method comprises introducing a sheath into a uterus and determining a location of a fibroid using a visualization element within or on the sheath. Upon identification, a portion of the sheath is steered to position at least one treatment needle at the determined location. The needle is then anchored in uterine tissue and the fibroid treated with the needle.
