A leak detecting apparatus (1) for detecting a leak and determining the size of the leak in a suture repaired site (5) of a hollow organ (3), for example, a stomach, in a cavity (7), for example, the peritoneal cavity of a subject comprises a first insufflator (12) for insufflating the hollow organ (3) with a first gas, and a second insufflator (14) for insufflating the cavity (7) with a second gas. A gas detector (18) is provided for detecting the concentration of the first gas in gases exhausted from the cavity (7) through a communicating conduit (35). A flow meter (25) monitors the flow rate of the first gas to the hollow organ (3). First and second pressure sensors (15) and (16) monitor the static pressure of the first and second gases in the hollow organ (3) and the cavity (7), respectively. The apparatus (1) is operable in a first mode and a second mode. In both the first and second modes of operation a microprocessor (50) controls the second insufflator (14) for maintaining the pressure in the cavity (7) at a relatively low predefined pressure, and the first insufflator (12) for maintaining a constant predefined pressure differential between the pressures in the hollow organ (3) and the cavity (7) of approximately 7 mmHg. In the first mode the microprocessor (50) determines the size of the leak as a function of the pressure differential and the concentration of the first gas in the exhaust gases. In the second mode of operation the microprocessor (50) determines the size of the leak as a function of the pressure differential and the flow rate of the first gas to the hollow organ (3) with the hollow organ (3) sealed apart from the sutured site (5).

Described herein are methods for repairing tissues (e.g., a meniscus, anterior cruciate ligament, rotator cuff, etc.) using collagen implants suitable. For example, the collagen implants are injected into a repair site to heal the tissue. Further described are collagen slurries, injectable collagen implants and methods of preparation thereof.

A method to remove a memory metal orthopedic staple from that is implanted in a bone repair site is disclosed. The orthopedic staple is in its relaxed state and the method includes (a) attaching an inserter tool / cartridge assembly to the orthopedic staple's bridge portion; (b) actuating the inserter tool to change the orthopedic staple from its relaxed state to its insertion state in which the two legs of the orthopedic staple are substantially parallel to each other; and (c) removing the orthopedic staple from the bone repair site.

Described herein are collagen slurries and collagen implants suitable for injection into a repair site to repair a tissue, for example, an anterior cruciate ligament, rotator cuff tendon, and / or a meniscus. Further described are systems including collagen implants, methods of preparing collagen slurries and implants, and methods of use thereof.

Methods and devices for the repair of a ruptured ligament using a scaffold device are provided. Aspects of the invention may include a scaffold attached by one or more sutures to one or more anchors. In aspects of the invention, the anchors may be secured to a bone near or at the repair site.

The present disclosure relates to a computer-assisted dental restoration system (102) configured to estimate a crown pose and represent a virtual crown in a three-dimensional model (110). The system obtains a three-dimensional model (110) of a patient's teeth, segments the three-dimensional model to obtain segmented tooth data, and generates an encoded three-dimensional model representation suitable for being processed by a trained neural network (112). A method of generating an encoded three-dimensional model representation includes downsampling a point cloud (404) representation based on segmented tooth data, determining a surface normal representation for each point, retrieving a dental marker for a repair site, encoding each point with a corresponding surface normal representation and a value associated with the repair site to produce an encoded three-dimensional model representation, and generating a three-dimensional model representation based on the encoded three-dimensional model representation. The encoded three-dimensional model representation is input into a trained neural network and an output is generated using the trained neural network, where the output includes a prediction of translation of each point in the encoded three-dimensional model representation to correspond to the crown pose.

An arthroscopic system for repairing torn ligaments is provided. An aspect of the present invention includes a scaffold that surrounds a graft, is attached to a fixation device by sutures, and is inserted into the repair site via an arthroscopic instrument. The scaffold, graft, and sutures are further fixed near or to the repair site via an arthroscopic instrument having an elongated delivery member containing the scaffold, graft, and sutures, prior to insertion of the scaffold, graft, and sutures into the repair site.
