Medical wraps

A medical wrap comprising a flexible, sheet-form substrate carrying a field of fibers exposed on one side thereof for engagement by fastener elements;

• and an array of fastener elements extending from a side of the substrate opposite the exposed fibers, the fastener elements each having a respective stem extending integrally with a film of resin disposed in a band across the substrate and encapsulating surface features of the substrate, the fastener elements constructed to snag the exposed fibers when the substrate is wrapped about living tissue in an overlapping manner, to secure the wrap about the tissue;
• wherein the fastener elements and field of fibers are configured to enable removal of the wrap from the tissue by application of a peeling force of less than about 0.2 pounds of force per transverse inch of engaged width of the engaged fastener elements, to limit tissue trauma during wrap removal.

A thermic treatment wrap comprising a flexible, sheet-form substrate carrying both a field of fibers exposed on one side thereof for engagement by fastener elements, and an array of fastener elements extending from a side of the substrate opposite the exposed fibers adjacent one end of the substrate, the fastener elements each having a respective stem extending from and formed integrally with a film of resin disposed in a band across the substrate and encapsulating surface features of the substrate;

• the wrap defining a pouch containing a material activatable to initiate a thermic reaction, for transferring heat with respect to a patient about which the wrap is wrapped in overlapping manner, with the fastener elements engaging the fibers of the substrate to hold the pouch against the patient, wherein the fastener elements and field of fibers are configured to enable removal of the wrap from the tissue by application of a peeling force of less than about 0.2 pounds of force per transverse inch of engaged width of the engaged fastener elements, to limit tissue trauma during wrap removal.
