  • Polymer-Based Occlusion Devices, Systems and Methods
    Publication number: 20130035665
    Abstract: A method of occluding includes imbibing a porous elongate element comprised of ePTFE with a calcium-containing solution. The method also includes delivering, via a delivery catheter, the calcium-imbibed porous elongate element to a target occlusion site. The method further includes administering, after the calcium-imbibed porous elongate element has been completely delivered to the target occlusion site and resides entirely within a volume defined by the target occlusion site, an alginate-containing solution to the target occlusion site.

  • Surgical implant system
    Patent number: 6810880
    Abstract: A surgical system, including a sealable pouch or envelope with surgical implements in the envelope is disclosed. The envelope is formed by the folds in a membrane and includes adhesive on the envelope to adhere the envelope to the surgical site. The system may include a port in the membrane to communicate between the interior and exterior of the envelope. When used for implant surgery, the port helps to provide sterile access to the implant site and also helps to ensure that the implant site does not become contaminated. The adhesive helps to position the system to the patient, and placement of the surgical implements inside the envelope helps to ensure sterility of the implements. The envelope can be opened over the surgery site and adhered to the incision site on the patient, thereby forming a sterile field.
