  • Publication number: 20200398029
    Abstract: A needle-injection catheter includes a catheter body having a distal end, a proximal end, a stiff proximal portion, a flexible distal portion, and a delivery lumen extending therethrough. In a first embodiment, a straight injection needle extends coaxially from a distal tip of the flexible portion of the catheter body, and a plurality of penetration limiting elements positioned circumferentially about a base of the straight injection needle and configured to fold radially inwardly against a shaft of the needle when constrained in a tubular lumen and to extend radially outwardly when unconstrained. In a second embodiment, a helical needle extends from the distal tip of the flexible portion of the catheter body. The helical needle has at least one helical delivery lumen connected to receive an injectable substance from the delivery lumen of the catheter body.

  • Patent number: 10550341
    Abstract: Methods are provided for producing lubricant base stocks from deasphalted oils formed by sequential deasphalting. The deasphalted oil can be exposed a first deasphalting process using a first solvent that can provide a lower severity of deasphalting and a second deasphalting process using a second solvent that can provide a higher severity of deasphalting. This can result in formation of at least a deasphalted oil and a resin fraction. The resin fraction can represent a fraction that traditionally would have been included as part of a deasphalter rock fraction.

  • Patent number: 10515208
    Abstract: Architecture that provides a secure environment in which data (e.g., code, instructions, files, images, etc.) can be opened and run by a client application. Once opened the data can be viewed (in a “protected view”) by the user without incurring risk to other client processing and systems. Accordingly, the architecture mitigates malicious attacks by enabling users to preview untrusted and potentially harmful data (e.g., files) in a low risk manner. Files opened in the protected view are isolated from accessing key resources on the client computer and provides the user a safer way to read files that can contain dangerous content. The protected view also provides a seamless user experience. The user is unaware that the client is operating on data in a different mode and allows for the reduction of security prompts.

  • Publication number: 20190216491
    Abstract: A surgical instrument end effector assembly includes a first jaw member defining an insulative tissue-contacting surface and first and second electrically-conductive tissue-contacting surfaces, and a second jaw member positioned including an ultrasonic blade body and defining at least one electrically-conductive tissue-contacting surface. The first jaw member is movable relative to the second jaw member between a spaced-apart position and an approximated position to grasp tissue therebetween. The second jaw member is movable relative to the first jaw member between a first configuration, to facilitate transmission of ultrasonic energy to tissue grasped between the first and second jaw members, and a second configuration, to facilitate conduction of electrosurgical energy through tissue grasped between the first and second jaw members.

  • Patent number: 10335181
    Abstract: An ultrasonic surgical instrument includes a transducer assembly having a distal engagement member and configured to supply ultrasonic energy. A waveguide defines a longitudinal axis and has a proximal engagement member configured to threadingly engage the distal engagement member. The waveguide is configured to transmit the ultrasonic energy therealong to a distal end thereof for treating tissue. A torque member is coupled to the transducer assembly and is disposed about the longitudinal axis. The torque member is selectively rotatable about the longitudinal axis and relative to the waveguide to threadingly engage the transducer assembly and the waveguide to one another. The torque member includes a plurality of fingers pivotably coupled thereto and movable between a closed position and an open position. In the open position, each finger extends substantially perpendicularly from the longitudinal axis to define a moment arm that facilitates the engagement of the transducer assembly and the waveguide.
