Abstract
Disclosed herein is an implantable medical device for implantation against cardiac tissue in the administration of electrotherapy to the cardiac tissue. The device includes a distal end and a monolithic controlled release device. The distal end includes a housing structure and a cavity within the housing structure. The cavity opens exterior the implantable medical device via a distal opening. The monolithic controlled release device is within the cavity and proximal the distal opening. The monolithic controlled release device includes a distal face, a proximal face opposite the distal face, an outer circumferential surface extending between the distal face and the proximal face, and a spline-shaped inner lumen extending between the distal face and the proximal face and radially inward from the outer circumferential surface. The monolithic controlled release device further includes an active pharmaceutical ingredient.
