  • Patent number: 11197665
    Abstract: A needle reload device includes a loading assembly including a needle holder pulley and a needle release arm. The needle holder pulley includes a base including first and second portions configured to receive a needle. The needle release arm is transitionable between an engaged state, in which the needle release arm engages the needle holder pulley to inhibit rotation of the needle holder pulley, and a disengaged state, in which the needle release arm is disengaged from the needle holder pulley such that the needle holder pulley is rotatable. When the needle release arm is in the engaged state, the first portion of the needle holder pulley is positioned between jaws of a stitching device, and when the needle release arm is in the disengage state, the second portion of the base of the needle holder pulley is positioned between the jaws.

  • Patent number: 11179236
    Abstract: This invention relates to the design and function of a compressible valve replacement prosthesis which can be deployed into a beating heart without extracorporeal circulation using a transcatheter delivery system. The design as discussed focuses on the deployment of a device via a minimally invasive fashion and by way of example considers a minimally invasive surgical procedure preferably utilizing the intercostal or subxyphoid space for valve introduction. In order to accomplish this, the valve is formed in such a manner that it can be compressed to fit within a delivery system and secondarily ejected from the delivery system into the annulus of a target valve such as a mitral valve or tricuspid valve.

  • Patent number: 11173028
    Abstract: A device can be introduced into the right atrium of a subject's heart by introducing the distal end of a hollow, straight, and stiff shaft into the subject's right internal jugular vein, and advancing the distal end of the shaft into the right atrium via the superior vena cava. The position of the distal end of the shaft is adjusted by manipulating a handle affixed to a portion of the shaft that remains outside the subject's body. The handle can be used to rotate the shaft about its longitudinal axis, rotate the shaft about an anterior-posterior axis, rotate the shaft about a medial-lateral axis, and/or advance the shaft in the caudal direction. A device is advanced through the interior of the shaft until the device extends beyond the distal end of the shaft and into the right atrium.

  • Patent number: 11147562
    Abstract: An aneurysm treatment system that includes an embolic implant, a delivery system, and an introducer sheath that are collectively designed so that the combination of the introducer sheath and the delivery system can be used as a deployment apparatus for the embolic implant. The delivery system can have a pull wire, a delivery tube, and an interference feature attached to the pull wire and positioned near a proximal end of the delivery tube. Rather than being discarded, the introducer sheath can be moved proximally over the delivery tube until it engages the interference feature. To deploy the implant, the introducer sheath can be pressed against the interference feature, causing the interference feature to move proximally in relation to the delivery tube, thereby proximally pulling the pull wire to which the interference feature is attached and deploying the implant.

  • Patent number: 11129713
    Abstract: A prosthetic heart valve delivery system can include a catheter portion having a sheath that can cover and uncover the prosthetic heart valve mounted on an inner shaft, a handle having a sheath actuator operatively coupled to a proximal portion of the sheath, the inner shaft extending through the handle, and a shaft retractor releasably coupled to a proximal portion of the handle and fixedly coupled to a proximal portion of the inner shaft. A sheath actuator can move the sheath axially relative to the inner shaft when the shaft retractor is coupled to the handle, and a proximal movement of the sheath relative to the inner shaft can cause the sheath to uncover the prosthetic heart valve. The shaft retractor can be operable to retract the inner shaft and the nosecone proximally relative to the sheath when the shaft retractor is released from the handle.

  • Patent number: 11123062
    Abstract: The technical problem to be solved by the present invention is to design a cosmetic surgical method for presenting a deeper or longer philtrum at the lip by adjusting the muscle flaps at the lips and nose. The theoretical basis of this surgical method is a “theory of labionasal muscle tension thread group” summarized from a series of studies with respect to anatomy, biomechanics and clinical surgical verification. According to this theory, the labionasal muscle tension structure is reconstructed by surgical adjustment of the position and direction of the muscle flaps, so as to produce an effect of changing the profile of the “philtrum” and to improve or remodel the “philtrum” as an aesthetic labial structure.

  • Patent number: 11116500
    Abstract: A surgical device is provided and includes a handle housing, an endoscopic assembly, and a follower assembly. The endoscopic assembly extends distally from the handle housing and includes an inner tube defining a longitudinal axis. The inner tube includes a distal portion defining a pair of opposed tines. The endoscopic assembly is configured to support a plurality of anchors at least partially therein. The follower assembly is disposed at least partially within the inner tube at a location proximal of the plurality of anchors, and includes a head and a shaft. A portion of the head is disposed between the pair of opposed tines. Actuation of the endoscopic surgical device causes rotation of the inner tube about the longitudinal axis relative to the handle housing, and causes distal advancement of the follower assembly relative to the inner tube.
