  • Patent number: 12011158
    Abstract: A surgical stitching device is configured for single hand operation that enables passage of a suture needle through tissue with minimal operational requirement. The surgical needle is selectively securable to first and second jaws that are pivotably coupled to each other. When the first and second jaws are in an open configuration, in which, the first and second jaws are spaced apart, the suture needle is detachably secured to the first and second jaws. When the first and second jaws are in a closed configuration, in which, the first and second jaws are approximated, the suture needle is detachably secured to one of the first and second jaws and is detached from the other one of the first and second jaws. Such single hand operation facilitates procedures such as, e.g., extraterritorial loop suture closure.

An end effector includes a pair of opposing first and second jaw members operably coupled about a common pivot. One or both of the jaw members includes a camming slot configured to engage the cam pin. Each jaw member includes an electrically conductive tissue sealing surface adapted to connect to a source of electrosurgical energy. A knife blade is supported in the elongated shaft and moveable in a longitudinal direction to cut tissue disposed between the jaw members. A switch is configured to be engaged by the actuating mechanism to initiate delivery of electrosurgical energy to tissue.

  • Patent number: 12011380
    Abstract: Methods, apparatuses and systems are described for deploying a stent into a body lumen. A stent delivery system may include a sheath with a partially-tubular first portion made from a first material and a second portion made from a second material that is adhered to the first portion to form a tubular body. In some cases, the first material may be chemically incompatible with the second material such that the adhesion between the first portion and second portion is free from cross-linked bonds. The stent delivery system may further include a guidewire lumen with a distal tip that may be slidably disposed within the sheath and a tubular stent disposed between the guidewire lumen and an inside surface of the sheath. The sheath may be formed by coextruding the first material and the second material to form a striped tubular body of the sheath.

  • Patent number: 12008760
    Abstract: Systems and methods of estimating movement of anatomical structures of a new patient include learning one or more deformation models from preoperative and intraoperative imaging data of a set of other patients and estimating movement of anatomical structures of the new patient based on the one or more deformation models and preoperative imaging data of the new patient. Estimating movement of the anatomical structures may include applying deformation models to map data derived from preoperative imaging data of a new patient to obtain deformed map data for each deformation model, and determining the deformation model that best fits the intraoperative imaging data of the new patient. Applying a deformation model to map data may include applying a transformation to the deformation model and interpolating to obtain a deformed map data. Registration is computed between locations of a medical device sampled during navigation of the medical device through the new patient and the original and deformed map data.
