  • Publication number: 20130152941
    Abstract: The various embodiments simplify the delivery of an occlusive implant to a hollow anatomical structure, such as a fallopian tube. For example, the delivery devices don't need to be retracted manually to deploy the implant. When the devices are activated, stored energy or a powered drive member induces movement of the various components. The operator need only position the distal ends of the devices at the treatment site and then commence deployment by, for example, flipping a switch or changing the position of an activation button. The present embodiments thus increase the efficacy of occlusion procedures by reducing the likelihood of operator error.

  • Publication number: 20100280328
    Abstract: A method comprising (a) illuminating a blood vessel in a relatively low-light surgical field by inserting a subcutaneous light source into tissue near the blood vessel and to a first location in the tissue underlying the blood vessel, and causing emission of light from the subcutaneous light source while the subcutaneous light source is at the first location, so that light from the subcutaneous light source passes through the tissue near the blood vessel, toward an observer; (b) drawing a portion of the tissue near the blood vessel through an incision in the skin; and (c) illuminating the drawn portion of tissue by activating an external light source in a hands-free manner, thereby facilitating determining whether the drawn tissue is the blood vessel.
