  • Publication number: 20240135761
    Abstract: A movable barrier operator comprising a motor, communication circuitry configured to receive a control signal and communicate with a door lock associated with a passageway door, and a controller. The controller is configured to authenticate the control signal, wherein authenticating the control signal includes associating the signal with a first level of access or a second level of access. The controller is further configured to communicate with the door lock via the communication circuitry to permit opening of the passageway door in response to associating the control signal with the first level of access and inhibit opening of the passageway door in response to associating the control signal with the second level of access. The controller is configured to cause the motor to open the movable barrier regardless of association of the control signal with the first level of access or the second level of access.

  • Patent number: 11964142
    Abstract: A syringe assembly includes a syringe and a tamper evident cap disposed over a Luer connection of the syringe, the tamper evident cap having a main body that defines a proximal end defining an opening, a distal end opposite the proximal end along the axial direction, an outer surface, and an inner surface opposite the outer surface that defines a passage to receive a tip cap and the Luer connection, where the tamper evident cap is spaced from the tip cap. The main body further defines a frangible connection between the proximal and distal ends of the main body. The frangible connection can break under a force applied to the distal end of the tamper evident cap such that the proximal end of the tamper evident cap remains engaged with the syringe when the frangible connection breaks.

  • Publication number: 20240016632
    Abstract: The present disclosure provides a method including positioning a first guidewire within a primary guidewire lumen of a multi-lumen tapered tip. A second guidewire is positioned within a secondary guidewire lumen and a shared guidewire lumen of the multi-lumen tapered tip, the second guidewire preventing the first guidewire from entering the shared guidewire lumen. A delivery system including the multi-lumen tapered tip is advanced over the second guidewire. By advancing the delivery system over a single guidewire, any possibility of entanglement of multiple guidewires during advancement of the delivery system is eliminated. The method further includes a guidewire exchange including releasing the second guidewire from the shared guidewire lumen, advancing the first guidewire through and out of the shared guidewire lumen, and advancing the delivery system over the first guidewire to a deployment location.

  • Publication number: 20230225890
    Abstract: A stent graft delivery system. The system includes a stent graft cover having a central longitudinal axis. The stent graft cover houses a first guidewire lumen extending along a first guidewire lumen axis and configured to track along a first guidewire. The first guidewire lumen axis is offset the central longitudinal axis. The stent graft delivery system further includes a tapered tip extending distally from the stent graft cover and defining an offset through-channel extending within the tapered tip along a tapered tip offset axis and configured to track along the first guidewire. The first guidewire lumen axis and the tapered tip offset axis extend along a common axis.

  • Patent number: 11612505
    Abstract: A stent graft delivery system and method of assembling the same is disclosed. The stent graft delivery system includes a stent graft cover configured to maintain a stent graft in a constricted configuration, and is configured to slide relative to the stent graft to enable the stent graft to expand radially outwardly. The stent graft cover extends along a first central axis. A tapered tip defining an opening therethrough is configured to track along a guidewire. The opening extends along a second central axis that is offset from the first central axis. This provides a delivery system with an opening in a leading edge that is not center relative to the outer stent graft cover.

  • Publication number: 20230030051
    Abstract: A delivery system for delivering an endovascular graft within a blood vessel. The delivery system includes a tip assembly including a tip and a sleeve having a proximal end. The delivery system includes a tip capture mechanism. The tip assembly is configured to move axially relative to the tip capture mechanism and between a delivery position and a release position. The tip capture mechanism includes a landing zone. The delivery system includes a travel limiter configured to align the proximal end with the landing zone when the tip assembly is in the release position to facilitate removal of the delivery system from the blood vessel.

  • Publication number: 20210378852
    Abstract: A delivery catheter includes a tip, a spindle and a lock mechanism. The tip includes a tapered portion and a tip sleeve. The tip sleeve extends proximally and has a lumen. The spindle includes a plurality of spindle pins. The lock mechanism locks the tip sleeve to the spindle to prevent relative longitudinal movement between the spindle and the tip sleeve. The delivery catheter includes a delivery configuration with the tip sleeve covering the spindle pins and a release configuration with a proximal end of the tip sleeve distal of the spindle pins. The lock mechanism locks the prosthesis delivery system in the release configuration. Each spindle pin of the plurality of spindle pins includes a smooth, curved profile.

  • Patent number: 9173738
    Abstract: A delivery system for use with a prosthetic heart valve having a stent frame to which a valve structure is attached includes a shaft assembly including a distal end, an intermediate portion, and a first coupling structure disposed near the distal end and configured to be coupled to a distal end of the prosthetic heart valve via a first tether. A sheath assembly defines a lumen sized to slidably receive the shaft assembly. The delivery system is configured to transition from a loaded state in which the sheath assembly encompasses the prosthetic heart valve to a deployed state in which the sheath assembly is withdrawn from the prosthetic heart valve. The first coupling structure is configured to be manipulated in a first direction to provide a controlled expansion or contraction of the distal end of the prosthetic heart valve.

  • Patent number: 8852271
    Abstract: A delivery system for percutaneously delivering and deploying a stented prosthetic heart valve. The delivery device includes a delivery sheath slidably disposed over an inner shaft, and a capture assembly. The capture assembly includes a spindle and a biasing member. The spindle is attached to the inner shaft and defines slot. The biasing member is disposed within the slot and self-transitions from a deflected condition to a normal condition. In a delivery state, the delivery sheath retains the prosthesis over the inner shaft and coupled to the spindle via the capture slot, including a portion of the prosthetic valve being engaged within the slot and the biasing member forced to the deflected condition. In a deployment state, the delivery sheath is proximally withdrawn and the biasing member self-transitions toward the normal condition to eject the prosthetic valve from the capture slot.
