Abstract
A tissue retention belt for retracting and retaining tissue in a position that permits access to a body portion of a patient for a medical procedure includes a flexible elongate body, a gripping portion affixed to the elongate body at the intermediate portion, and at least one attachment surface disposed at a proximal portion and/or a distal portion of the elongate body. The elongate body may include a first material having a first coefficient of friction, and the gripping portion may include a non-adhesive second material having a second coefficient of friction greater than the first coefficient of friction and defining a slip resistant exterior gripping portion. The tissue retention belt can be positioned or wrapped around a patient's body (e.g., pannus, thigh) such that the gripping surface contacts and grips the patient's skin to retract and retain the skin at the position to provide access for a medical procedure.
