In various examples, a hub for a medical device includes a hub housing including a passage from a proximal end of the hub housing to a distal end of the hub housing. A valve is disposed within the hub. The valve is configured to allow passage of an insertable device through the valve while inhibiting leakage of fluid from the valve. A cap is engaged to the hub housing. The cap includes an opening therethrough sized and shaped to allow passage of the insertable device through the opening. The opening allows access to the passage of the hub housing. An angled sidewall is disposed within the hub. The angled sidewall is configured to retain and deform the valve into a curved shape.

The present disclosure is drawn to an access device that includes a cannula with a joint lumen therethrough, and a hub coupled to a proximal end of the cannula. The hub includes at least two arms. The first arm may have a first lumen and a first hemostatic valve, the first lumen operably connected to the joint lumen, where the first lumen and the first hemostatic valve are configured for passage of a medical device, and the second arm may be coupled to the first arm and have a second lumen, the second lumen operable connected to the joint lumen, the second arm configured to be operably coupled to an external medical device, such as an extracorporeal membrane oxygenation (ECMO) device.
