Abstract

Intravesical devices are provided that are wholly deployable within the bladder of a patient in need of treatment and are well tolerated by the patient. The device may include an elastic body having a retention shape having (i) dimensions that provide intravesical mobility and that prevent voiding of the medical device through the urethra, and (ii) dimensions, buoyancy, or both, that exclude the medical device from entering the orifices of the ureters. The elastic body may exert a maximum acting force less than 1 N when compressed to a shape with a maximum dimension in any dimension of 3 cm. The device may include a drug for controlled release within the bladder, for treatment of the bladder or a regional tissue. Methods of treatment are also provided that include selecting a patient in need of treatment in the bladder where tolerability of the treatment is a primary concern.
