Abstract
A medical device includes an elongated member and a reinforced retention structure. The device can be used for draining substances from organs or abscessed areas within a body of a patient. The elongated member is made of a flexible material. The reinforced retention structure extends from or is formed integrally with the elongated member and comprises an elastic member and the flexible material. The reinforced retention structure provides retention strength while providing flexibility and patient comfort. The use of the reinforced retention structure also provides increased stability to the device within the patient's body and combats migration and/or expulsion of the device. The nature of the reinforcement in the retention structure may extend into the elongated member, which allows for larger drainage openings in the device and increases the radiopacity of the device.
