A medical device may include a longitudinally extending body. The longitudinally extending body may define an exterior surface and be configured for into a body of a patient. The medical device may further include a sheath coupled to and surrounding at least a portion of the longitudinally extending body. The sheath may have a selectively expandable mesh of interconnected filaments defining openings between adjacent filaments of the mesh. Further, the mesh may be configured to expand to pass a medical device along the longitudinally extending body, between the sheath and the exterior surface, and through an opening between adjacent filaments of the mesh.
