Abstract
Abstract A wound closure device employs a porous bonding member which receives a flowable adhesive capable of providing long term wound support. The bonding member is positioned by a carrier member that is used to achieve initial apposition of the wound and which may later be removed. An intermediate barrier may be provided between the bonding pad and the wound site. Alternatively, a rigid applicator may be utilized for positioning the bonding pad at the wound site. The closure device can include a supply of flowable adhesive for adhering the bonding member to the skin of the patient. Suitable flowable adhesives are cyanoacrylates. A form of packaging supports the wound closure member for preapplication of the adhesive and can serve as a part of a sterile barrier package.
