  • Patent number: 11622760
    Abstract: A knotting assembly for surgical suture line has an outer tube and an inner tube being slidably mounted in the outer tube. The inner tube protrudes from the outer tube and forms a loop section between a distal end thereof and a distal end of the outer tube. A suture line is looped surround the loop section to form a pre-knot and a loop. The suture has an inner section being moveably inserted in the inner tube. The loop is inserted by at least one second suture line. While the inner section is pulled, the second loop is closed to hold the at least one second suture line and folds the second suture line and pulls the folded second suture into the inner tube to finish the knot.

  • Patent number: 11607212
    Abstract: This invention relates to devices that join a pair of edges. Previously, suture assemblies used holes perpendicular to a vertical plane. Embodiments of the present invention use a first pad tunnel (130) between a first pad lower plane opening (126) and a first pad upper plane opening (122). A first pad tunnel major axis (132) passes through a first pad upper plane opening center (124) and a first pad lower plane opening center (128). For reference a first pad orthogonal axis (134) passes through the first pad upper plane opening center (124) orthogonal to the first pad upper plane (118) and the first pad lower plane (120). A first pad angle (?1) is measured clockwise from the first pad orthogonal axis (134) to the first pad tunnel major axis (132). The first pad angle is at least five degrees but no more than 175 degrees.

  • Patent number: 11559312
    Abstract: An embolic material which prevents flow of a biological fluid by being placed in a body lumen via a catheter, the embolic material comprising a material that swells by contacting the biological fluid. The embolic material includes a long filler that is formed smaller than an inner diameter of the catheter. The filler prevents the flow of the biological fluid by bending when brought into contact with the biological fluid due to the difference in swelling characteristics between a first side portion and a second side portion that extend parallel to one another in a longitudinal direction.

  • Patent number: 11547435
    Abstract: Featured is a surgical instrument including an end effector such as a rotating cutting implement and a heat transfer mechanism such as a cooling device, such as can include a phase change device, such as can be configured to absorb heat energy during the use of such a rotating cutting implement. The heat transfer mechanism can be configured so the absorbed heat energy is communicated to an external heat sink. Such a heat transfer mechanism can include a heat pipe, e.g., a scintered or wick type heat pipe. The heat energy is absorbed at one end of the heat pipe to minimize the potential for damage to the tissue and the like at and/or about the surgical site. Also featured are a surgical apparatus embodying such a surgical instrument and surgical or medical methods or procedures for manipulating, rotatably cutting, grinding, abrading or debriding tissue, bone or other structures or components of a mammalian body using such surgical instruments or surgical apparatus.

  • Patent number: 11534156
    Abstract: An instrument for performing thorascopic repair of heart valves includes a shaft for extending through the chest cavity and into a heart chamber providing access to a valve needing repair. A movable tip on the shaft is operable to capture a valve leaflet and a needle is operable to penetrate a capture valve leaflet and draw the suture therethrough. The suture is thus fastened to the valve leaflet and the instrument is withdrawn from the heart chamber transporting the suture outside the heart chamber. The suture is anchored to the heart wall with proper tension as determined by observing valve operation with an ultrasonic imaging system.

  • Patent number: 11529134
    Abstract: An apparatus and method are provided for a syndesmosis treatment construct configured to be placed into a cinched configuration that presses a first bone against a second bone. The syndesmosis treatment construct comprises a proximal fixator to contact the first bone and a distal fixator to contact the second bone. A first suture and a second suture are parallelly looped through the distal fixator. A free splice slidably rides on proximal ends and distal ends of both of the first and second sutures. The distal ends are looped through the proximal fixator and bound within a stitch splice. The proximal ends are passed outside of the stitch splice and through the proximal fixator. The free splices compress and seize the proximal ends during pulling of the proximal ends by a practitioner so as to maintain the cinched configuration.

  • Patent number: 11523925
    Abstract: Systems and methods for treating eating disorders using electro-physiologically active transducer intragastric balloon system (“EAT system”) are described herein. The EAT System includes an intragastric balloon that is configured to operate in a typical fashion and further modified to include an integrated electro-physiological stimulation unit. The stimulation unit is configured to generate impulses using a transducer that are suitable for stimulating sensory receptors located around the stomach. In particular, transducer transmits mechanical waves through the fluid within the IG balloon and its outer shell to any receptors of the vagus nerve system that are located in the vicinity of the IG balloon. Controlled stimulation of the vagus nerve fibers using the stimulation unit can effectively produce appetite controlling sensations of satiety beyond the typical efficacy period of an unmodified IG balloon.
