A medical procedure access kit for inserting a medical device into a biological tubular structure includes at least one semi-flexible sheath and at least one semi-flexible angled guidewire. The sheath defines an internal side wall and an external side wall. The sheath includes a longitudinal opening defined by the internal side wall, a pre-formed bend along a length of the sheath, and a side hole disposed on the pre-formed bend and extending from the external side wall to the internal side wall. The angled guidewire is sized and configured so that it can be received within the sheath.
