Abstract: The present disclosure relates generally to the assessment and imaging of bodily organs, including transesophageal echocardiography (TEE). For example, some embodiments of the present disclosure provide for a TEE probe having removable or modular components, such that the TEE probe can be disassembled and reassembled by a physician. In some embodiments, the TEE probe may be compatible with components, such as gastroscopes, having various differences in size, shape, and configuration. In some embodiments, a TEE probe may comprise a gastroscope and a handle, wherein the handle and the gastroscope are removably coupled to one another by an interface, such that when the gastroscope and handle are removably coupled, a user can control various functions of the gastroscope, such as the ultrasonic imaging of an ultrasonic transducer of the gastroscope, and the movement of a distal portion of the gastroscope.

Abstract: The present disclosure relates generally to the assessment and imaging of bodily organs, including transesophageal echocardiography (TEE). For example, some embodiments of the present disclosure provide for remote and/or wireless control of a transesophageal echocardiography (TEE) probe. For example, in some embodiments a TEE probe comprises a gastroscope for insertion into a patient's esophagus, a handle coupled to the gastroscope, and a wireless module coupled to the handle and configured to receive a command signal from a user to remotely control aspects of a TEE scan. Some aspects to be controlled by a user remotely may include movement of a distal portion of the gastroscope within the patient's esophagus. Other aspects may include initiation of an ultrasonic imaging procedure by an ultrasonic transducer. In some embodiments, the wireless module may also be configured to wirelessly transmit electrical signals to a console.

Abstract: A system and method provide haptic feedback with respect to the maneuvering of a distal tip at a distal end of a transesophageal echocardiogram (TEE) ultrasound transducer probe deployed in a patient. An acoustic imaging system is connected to the TEE ultrasound transducer probe and produces acoustic images in response to one or more signals from the TEE ultrasound transducer probe. A control apparatus is provided for maneuvering the distal tip of the TEE ultrasound transducer probe with respect to the patient. A contact force sensing device senses a contact force between the distal tip of the TEE ultrasound transducer probe and the patient, and a feedback mechanism provides tactile, audio, and/or visual feedback when the contact force between the distal tip of the TEE ultrasound transducer probe and the patient exceeds a threshold force.

Abstract: A semi-invasive ultrasound imaging system for imaging biological tissue includes a transesophageal probe or a transnasal, transesophageal probe connected to a two-dimensional ultrasound transducer array, a transmit beamformer, a receive beamformer, and an image generator. The two-dimensional transducer array is disposed on a distal portion of the probe's elongated body. The transmit beamformer is connected to the transducer array and is constructed to transmit several ultrasound beams over a selected pattern defined by azimuthal and elevation orientations. The receive beamformer is connected to the transducer array and is constructed to acquire ultrasound data from the echoes reflected over a selected tissue volume. The tissue volume is defined by the azimuthal and elevation orientations and a selected scan range. The receive beamformer is constructed to synthesize image data from the acquired ultrasound data.

Abstract: A three dimensional ultrasonic diagnostic imaging system is operated to guide or observe the operation of an invasive medical device (30) in three dimensions. An interventional system (20) is used to operate the invasive medical device (30) and produces spatially-based information relating to the activity of the invasive medical device (30). The spatially-based information from the interventional system (20) is merged into the three dimensional ultrasonic image data to produce a live three dimensional image of the invasive medical device (30) or its activity. In one embodiment the locations where the activity of the invasive medical device (30) is performed is recorded and displayed in the three dimensional ultrasonic image. The three dimensional ultrasonic image may be shown as an anatomical volume rendered image or as a wire frame model (130) of the anatomy. In another embodiment an integrated three dimensional ultrasonic imaging and invasive device system is described.

Abstract: Control mechanism (10) for an endoscope including first and second independently rotatable control knobs (18,20), an inner pinion shaft (22) fixed to the first control knob (18), an outer pinion shaft (28) fixed to the second control knob (20) and coaxial with the inner shaft (22) and an intermediate shaft (34) arranged at least partially inside of the outer shaft (28) and at least partially around the inner shaft (22). O-rings (42,46) between the intermediate shaft (34) and the inner and outer shafts (22,28) seal the interior of the endoscope and transfer torque from the inner or outer shaft (22,28) to the intermediate shaft (34), which is grounded against rotation and therefore does not transfer torque to the other shaft (22,28). A non-cross-coupling control mechanism is achieved in which the rotation of one control knob and its associated shaft does not have any effect on the other control knob and associated shaft.

Abstract: A three dimensional ultrasonic diagnostic imaging system is operated to guide or observe the operation of an invasive medical device (30) in three dimensions. The appearance of the invasive device (30) in the three dimensional ultrasonic image is enhanced to be more readily observable by a clinician. The enhancement is produced by transmitting a greater ultrasonic beam density in a subvolumetric region including the invasive device (30) than in the surrounding portion of the volumetric region (120). The beam density may be uniformly high in the subvolumetric region and uniformly low in the surrounding region, or may taper from a relatively high beam density around the invasive device (30) to a minimum beam density at distances removed from the invasive device (30).

Abstract: A composite three dimensional ultrasound image containing position or image information of an invasive medical device (30) is provided. The three dimensional ultrasound image data can be combined with position or image information of the invasive medical device (30) either prior to or subsequent to volume rendering. the three dimensional ultrasound image data and the interventional system data are oriented and sealed to a common frame of reference and then combined. The volume rendering can be performed either on the ultrasound system (12), on the interventional system (20), or separately on both before combining.
