  • Patent number: 10745579
    Abstract: Extrudable compositions were prepared comprising poly(propylene) and a liquid additive comprising a lactam group. The compositions can comprise other optional additives that include a polyhemiaminal, antioxidants, UV light absorbers, and surfactants. The extruded compositions have higher percent elongation at break and lower Young's modulus compared to extruded poly(propylene) lacking the liquid additive. These and other property improvements make the extruded compositions attractive for forming field joint coatings for undersea pipeline applications.

  • Publication number: 20200214729
    Abstract: A surgical instrument includes an elongated shaft having a distal portion and a proximal portion coupled to a housing. An inner shaft member extends at least partially through the elongated shaft and is selectively movable in a longitudinal direction. An end effector is supported by the distal portion of the elongated shaft. The end effector includes upper and lower jaw members pivotally coupled to the distal portion of the elongated shaft about a pivot axis and including a pair of laterally spaced flanges. The pairs of flanges of the jaw members are arranged in an offset configuration such that one flange of the upper jaw member is positioned on a laterally exterior side of a corresponding flange of the lower jaw member, and the other flange of the upper jaw member is positioned on a laterally interior side of the other flange of the lower jaw member.

  • Patent number: 10702332
    Abstract: A forceps includes an end effector assembly having a stop and a plurality of overmold teeth within at least one jaw member. One (or both) of the jaw members is moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. One (or both) of the jaw members includes a stop molded within an insulative housing, and an insulator plate with the overmold teeth formed from plastic. The overmold teeth extend through openings within a sealing plate and protrude past the tissue sealing surface of the sealing plate. The stop primarily controls the gap distance between opposing jaw members by bearing most of an applied load and the overmold teeth assist in controlling the gap distance by bearing the remaining applied load.

  • Patent number: 10695123
    Abstract: A surgical instrument includes a housing, a shaft extending distally from the housing, an end effector disposed at a distal end of the shaft, an actuator operably coupled to the housing, an actuation assembly, and a sensor module. The actuation assembly extends through the housing and the shaft and includes a distal end operably coupled to the end effector or a component associated therewith, a proximal end operably coupled to the actuator, and a spring. Actuation of the actuator manipulates the end effector or deploys the component relative thereto. The sensor module is disposed within the housing and configured to sense a property of the spring indicative of an amount the spring has been compressed. The sensor module is further configured, based upon the sensed property, to determine a condition of the end effector or the relative position of the component.

  • Publication number: 20200115553
    Abstract: Resin compositions made of high-performance polymers blended with molecular glass as rheological modifiers are disclosed. The high-performance polymers include thermoplastics, such as polysulfones, polyimides, poly(ether imides), polyketones, poly(ether ketones), and combinations thereof. The molecular glasses are amorphous, non-oligomeric, and have one or more functional groups that promote miscibility of the molecular glass with the high-performance polymers to produce a resin composition with low melt viscosity. Incorporation of the molecular glasses into the high-performance polymers does not alter the Young's modulus and yield stress values of the high-performance polymers.

  • Publication number: 20200107845
    Abstract: A surgical instrument includes a housing having a first handle and an elongated shaft extending therefrom. An end effector is disposed at a distal end of the elongated shaft and includes first and second jaw members, the first jaw member including a staple cartridge configured to house a series of staples therein. A second handle is operably coupled to the housing and is selectively moveable relative to the first handle to actuate the first and second jaw members between an open position and a closed position for grasping tissue. A first switch is activatable to supply energy to one of the jaw members. A stapler mode switch is actuatable between an unactuated position wherein movement of the second handle moves the jaws to the second position and an actuated position wherein movement of the second handle moves the jaws to the second position and drives the staples through tissue.
