  • Publication number: 20250181984
    Abstract: Technologies are provided for optimizing candidate partners for a user interaction. The technologies can facilitate a trust in facts and identify mutual interest. The technologies can identify the location of users, share personalized information, provide tools for matching users to candidates, exchange data, advertise to users with tracking algorithms, create avatars, host digital interactions between users, and provide user assessments of other users. Nodes of users, and information on user behavior patterns can help identify matches. Users can share their current moods to communicate with other users. Machine learning is included for modeling a user's own feedback from actual interactions in a pool of candidates. The input to the model includes sets of interaction data on users, and the output from the model is an improved, modeled set of user preferences to improve the user's candidate pool. Images of virtual candidates can be created at each iteration of the model.

  • Publication number: 20250009360
    Abstract: Disclosed are example embodiments of an endovascular coil having a twisted figure 8 shape. The endovascular coil includes: a first loop; a second loop; and an inflection region where a portion of the first loop transitions into a portion of the second loop. The second loop is rotated about an axis parallel to the longitudinal axis of the first loop to create the twisted figure 8 shape. The twist adds more randomness and variability to the filling behavior of the endovascular coil. The added randomness and variability enables the twisted figure 8 coil to better fill the void of irregular-shaped aneurysms than other conventional embolic coils.

  • Publication number: 20240398397
    Abstract: Improved methods and devices for performing an endoscopic surgery are provided. Systems are taught for operatively treating gastrointestinal disorders endoscopically in a stable, yet dynamic operative environment, and in a minimally-invasive manner. Such systems include, for example, an endoscopic surgical suite. The surgical suite can have a reversibly-expandable retractor that expands to provide a stable, operative environment within a subject. The expansion can be asymmetric around a stabilizer subsystem to maximize space for a tool and an endoscope to each be maneuvered independently to visualize a target tissue and treat the target tissue from outside the patient in a minimally invasive manner.
