Abstract
A tissue retention belt for maintaining tissue in a position that permits access to a body portion of a patient for a medical procedure includes a first anchor zone, a second anchor zone, and a tension zone. The tension zone extends between the first anchor zone and the second anchor zone and defines a tension axis that extends in a direction of loading to be applied to retained tissue. The tension zone may include an auxiliary anchor zone that includes a removable non-adhesive and an adhesive surface configured to adhere to a patient's skin and provide auxiliary anchoring for maintaining tissue in position.
