Embodiment Construction

[0026] Over the past approximately 15-20 years, many interventional procedures on the heart (including aortic valve repair, mitral valve repair or replacement, patent foramen ovale closure, and atrial septal defect closure) have migrated from surgical approaches to the transcatheter approach. Transfemoral access is a common technique in which a small incision is made near the patient's groin to serve as an instrumented portal into the femoral vein and to the heart. In transcatheter intervention, the clinician introduces a long, flexible tool into the heart through the vasculature.

[0027] Transcatheter methods have become popular because they are less invasive to the patient and have a shorter postoperative recovery time than surgical procedures. At the same time, they are technically challenging processes due to the lack of dexterity, visualization and haptic feedback. Some of these functions are restored by techniques such as transesophageal echocardiography (TEE). In pa...

Abstract

The present invention generally relates to systems and methods for transesophageal echocardiography (TEE) automation. Some aspects relate to a TEE probe having an ultrasound transducer on a distal end of the TEE probe. In some embodiments, if the target is in a field of view (FOV) of the ultrasound transducer, the electron beam steering of the probe is adjusted; if the target is at the edge of the FOV, adjusting both the electron beam steering of the probe and the mechanical joint of the probe; and if the target is not in the FOV, only the mechanical joints of the probe are adjusted.

Description

technical field [0001] The following generally relates to systems and methods of transesophageal echocardiography (TEE). Background technique [0002] Transesophageal echocardiography (TEE) is a method for cardiac ultrasound imaging in which an ultrasound (US) probe includes a flexible tubular cable, wherein an ultrasound transducer is positioned at the distal tip of the flexible tubular cable . The TEE probe is inserted into the esophagus to place the TEE probe close to the heart. Existing TEE probes typically include mechanical joints that, along with controlled insertion distance and angling of the TEE probe and electron beam steering of the ultrasound imaging plane, allow great flexibility in positioning the ultrasound transducer and imaging plane. , in order to acquire the desired view of the heart. Concerns, however, include the risk of esophageal perforation and the difficulty of achieving the desired clinical view with a great degree of manipulation control under ...
