Tracking marker support structure and surface registration methods employing the same for performing navigated surgical procedures

Devices and methods are provide for facilitating registration and calibration of surface imaging systems. Tracking marker support structures are described that include one or more fiducial reference markers, where the tracking marker support structures are configured to be removably and securely attached to a skeletal region of a patient. Methods are provided in which a tracking marker support structure is attached to a skeletal region in a pre-selected orientation, thereby establishing an intraoperative reference direction associated with the intraoperative position of the patient, which is employed for guiding the initial registration between intraoperatively acquired surface data and volumetric image data. In other example embodiments, the tracking marker support structure may be employed for assessing the validity of a calibration transformation between a tracking system and a surface imaging system. Example methods are also provided to detect whether or not a tracking marker support structure has moved from its initial position during a procedure.

Simplified methods for non-invasive vasectomy
11291493 · 2022-04-05 ·

Conventional vasectomy techniques suffer from a number of potential complications, including, for example, a substantial risk for the development of hematomas, and swelling, and post-surgical pain, a potential for spontaneous duct reconnection and undesired resumption of fertility, a need for a highly skilled surgical professional, as well as a long recovery period, accompanied by severe limitations on post-surgical activity. The vasectomy methods of the present invention reduce and/or minimize contact with sensory nerves located on the distal side of the vas deferens, particularly the distal region of the outer vas deferens sheath, so as to minimize nerve damage and the post-surgical pain associated therewith. In addition, the methods of the present invention overcome the disadvantages and deficiencies of the prior art, resulting in a rapid, reliable, minimally-invasive male sterilization procedure that may be readily, reliably and successfully performed by minimally skilled personnel around the world in a variety of medical settings.

Self-adjusting device
11833049 · 2023-12-05 ·

A self-adjusting device configured to be placed in contact with tissue/organ and apply mechanical force to the tissue/organ to achieve an improvement of functioning of the tissue/organ. The self-adjusting capabilities can be carried out by three functional subsystems that can be packaged either in a single, integrated system or in separate modules. A sensing subsystem senses the tissue/organ and sends at least one type of sensing signal characteristic of functioning of the tissue/organ to a controlling subsystem. The controlling subsystem processes the signal with an algorithm to determine if a configuration of the device needs to be changed or a force applied to the tissue/organ needs to be changed. An actuating subsystem can be controlled by the controlling subsystem to affect the configuration/force change when needed. A feedback loop is provided to keep the controlling subsystem up to date as to the state of the actuating subsystem.

Ultrasonic surgical instrument with sliding blade sheath

A surgical instrument includes a gripping assembly, a shaft assembly, an end effector, and a pivoting member. The gripping assembly defines a first opening for receiving a finger or a thumb of a user. The gripping assembly includes a first deformable feature that is configured to be moved in order to increase or decrease a cross-sectional area of the first opening. The shaft assembly extends distally from the gripping assembly. The end effector is positioned at a distal end of the shaft assembly and includes a first member. The pivoting member is pivotably coupled with the shaft assembly. The pivoting member is pivotable with respect to the first member of the end effector between an open position and a closed position to thereby clamp tissue between the first member and the pivoting member.
