Surgical devices permitting a surgeon to access repeatedly tissue at a particular surgical site in a patient to perform multiple surgeries over time. The devices have two substantially planar and parallel leaves that are sterile, nonresorbable, and biocompatible. Each leaf forms a continuous structure and defines the entire longitudinal length of the device to accommodate the size and location of the surgical site. A base member is located in situ and adjacent the surgical site. An anchoring surface secures the device to the tissue of the patient at the surgical site. The leaves have a conjoined portion such that a manual force is required to separate the leaves, thereby expeditiously creating a pathway through which access to the tissue at the surgical site is realized with minimal tissue dissection, and the proximal ends of the leaves are not conjoined to facilitate separation of the leaves and creation of the pathway. |
