A method for closing a puncture wound on skin. The method including: adhering a first surface of a first member having an unrestrained shape to the skin and over the puncture; and subsequent to the adhering, removing a second member for restraining the first member in a restrained shape from the first member. Where at least a normal force is applied to the puncture wound due to the removal of the second member from the first member which causes the first member to change towards the unrestrained shape. The removing can further cause a force substantially perpendicular to the normal force which tends to close the puncture wound.

Glass-based particles of a biocompatible material which comprises 40 to about 80 wt % borate (B.sub.2O.sub.3) intermixed into a carrier which is an ointment, cream, or surgical glue.

A medical dressing is provided. The dressing has a central portion and a border portion, and comprises a backing layer, an adhesive body contact layer and a pad arranged in the central portion between the backing layer and the adhesive body contact layer. The pad is symmetric about a longitudinal center line and the dressing comprises a lobed portion on each side of the center line. The central portion of the dressing has a tensile strength in the longitudinal (y) direction of at least 60 N, preferably at least 70 N at an elongation of 25%, as measured by the test method ASTM D 882-12. The medical dressing may be used for pressure ulcer prevention, such as at the sacrum region of a human body.
