    Abstract: In one embodiment, a medical device includes an elongate member and a tissue anchor. The elongate member defines a lumen. The elongate member has a retention member disposed within the lumen. The tissue anchor has a first arm portion, a second arm portion, and a base portion extending between the first arm portion and the second arm portion. The tissue anchor has a first configuration and a second configuration. The first arm portion is substantially linear when the tissue anchor is in its first configuration and the first arm portion is non-linear when the tissue anchor is in its second configuration. The tissue anchor is biased to its second configuration. The tissue anchor is configured to be disposed within the lumen defined by the elongate member such that the retention member engages the tissue anchor to help retain the tissue anchor in its first configuration.

    Abstract: According to one aspect, the invention pertains to a ureteral stent that includes a proximal retention structure configured for retaining the proximal portion in the urinary bladder, which contains a balloon reservoir for storing a pressurized fluid that contains a urologically beneficial drug. In another aspect, a ureteral stent is provided that includes a reservoir for storing a pressurized fluid that comprises a urologically beneficial drug and an outlet remote from the reservoir, wherein the outlet includes a hydrogel material that, upon implantation of the ureteral stent, shrinks as the salinity of surrounding urine drops and expands as the salinity of surrounding urine increases. In other aspects, the invention pertains to a system for introducing a urinary stent into the body of a patient. In yet other aspects, the invention pertains to methods for treating patients.
