Patent number: 11116505Abstract: A buttress applier cartridge assembly includes a buttress assembly and a buttress applier cartridge. The buttress assembly includes a buttress configured to support a staple formed therein as well an adhesive layer for adhering to an end effector. The buttress applier cartridge includes a housing defining a gap extending in a longitudinal direction as well as a platform. The platform extends longitudinally from a proximal portion to a distal portion and is exposed in a transverse direction adjacent to the gap. The proximal and distal portions respectively have a proximal stiffness and a different, distal stiffness in the transverse direction. Thereby, the proximal and distal portions support the buttress assembly thereon to deform with the proximal and distal stiffnesses and provide reactionary forces of at least the predetermined minimum force while receiving the end effector for accommodating various camber orientations of the end effector.Type: GrantFiled: December 28, 2018Date of Patent: September 14, 2021Assignee: Cilag GmbH InternationalInventors: Michael J. Vendely, Trevor J. Barton, Emily A. Schellin, Mark S. Zeiner

Patent number: 11116506Abstract: Disclosed embodiments include apparatuses, systems, and methods for facilitating surgical anastomosis between bodily passages. In an illustrative embodiment, an eversion mechanism is configured to partially evert a distal portion of an opening of a receiving passage and further configured to leave a proximal portion of the opening of the receiving passage in a non-everted position. A donor support mechanism is configured to partially evert a distal portion of an opening at an end of a donor passage and further configured to leave a first proximal portion of the end of the donor passage in a non-everted position. The donor support mechanism is further configured to form a passage juncture at the end of the donor passage and the opening of the receiving passage. A suturing mechanism is configured to motivate a filament through a generally helical path around the passage juncture to suture the donor passage to the receiving passage.Type: GrantFiled: March 27, 2019Date of Patent: September 14, 2021Assignee: Gyrus ACMI, Inc.Inventors: Adam Lee Smith, Clifton A.

Patent number: 11116507Abstract: An end effector assembly for use with a circular stapler apparatus permits alignment of the staple forming pockets of the anvil assembly and the staples of the staple cartridge assembly regardless of the relative orientation of the components. The end effector assembly includes a cartridge housing, a staple retainer having a plurality of staples arranged in a circular array, a staple pusher at least partially disposed within the cartridge housing and configured for movement through a firing stroke to eject the staples from the staple retainer, an anvil rod configured for coupling relative to the cartridge housing, and an anvil head including at least one continuous circular staple forming pocket. The staple forming pocket is in registration with the staples for at least partial reception of the staples during the firing stroke. The staple forming pocket is configured for at least partially deforming the staples.Type: GrantFiled: March 9, 2017Date of Patent: September 14, 2021Assignee: Covidien LPInventor: Dongming Shen

Patent number: 11116508Abstract: An apparatus includes a body, a motor, a shaft, a stapling assembly, and an electrical potential shifting device. The body includes a firing switch configured to generate a motor drive signal including at least one of a motor activation signal portion or a motor deactivation signal portion. The motor includes a first power terminal and a second power terminal which define an electrical potential energy differential therebetween. The motor is configured to selectively activate and deactivate in response to the electrical potential energy differential. The first power terminal is coupled to a power supply and the second power terminal is coupled to the electrical potential shifting device. The electrical potential shifting device increases the electrical potential energy differential of the motor in response to detecting the motor activation signal portion and decreases the electrical potential energy of the motor in response to detecting the motor deactivation signal portion.Type: GrantFiled: September 26, 2019Date of Patent: September 14, 2021Assignee: Cilag GmbH InternationalInventors: Shane R. Adams, Nicholas J. Ross, Austin E. Wise

Patent number: 11116509Abstract: A system and method for delivering an embolic device are disclosed. In one embodiment, the system and method may be directed to a combination of a catheter, coupler, and embolic device. The coupler is disposed inside of the catheter. The embolic device is coupled with a retaining mechanism at the proximal end. Until the embolic device is delivered to a certain location within an artery, the embolic device is engaged with the catheter by engaging the coupler with the retaining mechanism. The embolic device is further secured to the delivery catheter by securing the coupler with a securing mechanism formed on the catheter. When the delivery catheter reaches the desired location in the artery, the embolic device is released from the delivery catheter by simply pulling the coupler proximally such that the loop portion of the coupler first becomes disengaged from the locking window and then from the retaining mechanism.Type: GrantFiled: November 10, 2017Date of Patent: September 14, 2021Assignee: Avantec Vascular CorporationInventors: Brett A Follmer, Ryan M Hoshino, Nicholas deBeer, Andrew Scott Huffmaster, Karl Sterling Halden

Patent number: 11116510Abstract: Systems, devices and methods for occluding the left atrial appendage (LAA). The device excludes the LAA from blood flow. The implantable device is delivered via transcatheter delivery into the LAA and secured within the LAA. The implant comprises an expandable and compliant frame and an expandable and conformable tubular foam body. A delivery and tether retraction system includes a handle for controlling a pusher and tether. The pusher may be moved a distance away from the implant without changing the orientation of the implant, while the tether is still attached to the implant. Severing the tether and proximally retracting a control on the hand piece by a distance causes the severed end to advance distally by at least about twice that distance. A loader includes a conical portion with guides and a reservoir for submerging the foam prior to loading and delivery.Type: GrantFiled: February 18, 2020Date of Patent: September 14, 2021Assignee: Conformal Medical, Inc.Inventors: David A. Melanson, Andy H. Levine, James H. Loper, Michael T. Radford, Carol Devellian, Aaron V. Kaplan, Ronald B. Lamport

Patent number: 11116511Abstract: A vascular plug comprises a superstructure expandable from a collapsed percutaneous insertion configuration to an expanded deployment or use configuration. The superstructure is comprised of both primary and secondary three-dimensional shapes allowing for the occlusion of a wide range of vessel sizes from small to large through a disproportionately small delivery catheter. The plug includes a shape memory element for the generation of radial force and the creation of the larger secondary three-dimensional twisting or helical superstructure as is needed for target vessel occlusion.Type: GrantFiled: April 9, 2019Date of Patent: September 14, 2021Inventor: John S. DeMeritt

Patent number: 11116512Abstract: A foam transfer or dispensing device is described which dispenses foam from a source of foam, typically a pressurised canister, and which enables efficient purging or air and an initial volume of foam from the device to ensure foam sterility and quality when a syringe is filled from the device. The device comprises a foam inlet arranged for communication with a source of foam, a foam pathway in fluid communication with the foam inlet and comprising a foam outlet, arranged for engagement by a syringe nozzle; and a waste outlet in fluid communication with the foam pathway. The foam pathway comprises a tubular projection arranged to extend through the foam outlet and into a syringe nozzle when a syringe is connected to the foam outlet, which improves the efficiency of the purging process and prevents pooling of air or foam. The device further comprises a means for restricting displacement of material through the waste outlet, so that the user can control the volume of foam that is wasted.Type: GrantFiled: February 27, 2017Date of Patent: September 14, 2021Assignee: Provensis LimitedInventors: David Dakin Iorwerth Wright, David Ian Faulkner
