Abstract
The present invention provides a hydrogel wound dressing substantially in the form of a rope and also in the form of a strand. The wound dressing comprises a hydrogel material substantially in a rope configuration or a strand configuration having a predetermined length for filling the cavity of a wound, and a dressing removal layer disposed within the strand configuration. The dressing removal layer may extend outwardly from an end so as to form a pull tab which facilitates removal of the rope configuration from the wound. The present invention also provides a wound dressing comprising a hydrogel material substantially in a strand configuration having a predetermined length for filling the cavity of a wound. The strand configuration also includes a dressing removal layer disposed within the strand configuration and may also include a pull tab which facilitates removal of the strand configuration from the wound.
