2 results about "Transcatheter aortic" patented technology

A system for implanting two or more implants into a heart of a patient may include a multi-device steerable guide catheter ("MDSGC"), a transcatheter edge-to-edge repair ("TEER") implant delivery device, and an additional implant delivery device for implanting an additional medical device. The additional medical device may be a collapsible and expandable prosthetic transcatheter aortic valve repair ("TAVR") device or a collapsible and expandable left atrial appendage ("LAA") occluder device. The MDSGC may have a first handle and may be steerable, the TEER delivery device may have a second handle, and the additional delivery device may have an additional handle. The system may include a fixation device to capture native heart valve leaflets therebetween as part of a TEER procedure. The TEER delivery device and the additional delivery device may each have a catheter sized and shaped to pass through an interior of a catheter of the MDSGC.

This invention provides an intelligent image measurement and navigation method and system for transcatheter aortic valve replacement (TAVR), relating to the field of medical auxiliary diagnosis. Utilizing a dual-temporal collaborative repair strategy, it can use the texture information of clear temporal phases to complete the anatomical details of blurred temporal phases, obtaining complete anatomical boundaries even under imperfect cross-sections. This significantly reduces the time and frequency of physical probe adjustments during surgery, lowering the reliance on the operational skills of anesthesiologists or sonographers. Through cascaded positioning with anatomical region locking, and using a probability field strength prior forced algorithm to focus on high-probability anatomical structures, it shields background noise that is easily interfered with by the human eye, ensuring the objectivity and consistency of measurement results. This allows less experienced surgeons to achieve measurement accuracy consistent with senior experts, providing standardized data support for valve model selection. It can intelligently filter out motion interference, ensuring the safety of intraoperative navigation, and its sub-pixel accuracy meets the requirements of refined TAVR surgery.
