  • Publication number: 20240124826
    Abstract: An electromagnetically driven one-dimensional stretching device includes a stretchable surface, and an electromagnetic actuator coupled to the stretchable surface. The electromagnetic actuator is configured to stretch the stretchable surface along one-dimension. A method can include spin-coating a weight ratio of about 10:1 about 1:1 of a polydimethylsiloxane resin to a curing agent mixture on a surface to form a stretchable surface, removing the stretchable surface from the surface, coupling an electromagnetic actuator to the stretchable surface, and stretching the stretchable surface along one-dimension using the electromagnetic actuator.

  • Patent number: 11369384
    Abstract: Methods, devices and systems are described for treating venous insufficiency in which the vein is compressed at least partially along a treatment zone. A system can be provided including an injection device, such as a glue gun, that is operably connected to a delivery catheter that can be advanced across a treatment zone in the vein. The delivery catheter can be used to deliver one, two, or more boluses of media (e.g., cyanoacrylate) to occlude the vein along different spaced-apart sections of the treatment zone. External compression can also be applied to the vein by a compression element, such as a hand or multifunctional ultrasound transducer, to occlude portions of the vein along the treatment zone prior to or during the introduction of the boluses of media.
