Abstract
Embodiments of the present invention provide an inverted strain relief design for a flexible member attached to an implantable housing by shaping the external surface of the housing with respect to the connection between the housing and the flexible member to control the bending radius of the flexible member. In one embodiment, an implantable device comprises an implantable housing having an opening for receiving a proximal portion of a catheter to form a connection at a location of the opening, the opening being disposed in a recessed region of an outer surface of the implantable housing, the outer surface in the recessed region having a profile with respect to the location of the opening, the profile limiting bending of the catheter around the outer surface of the implantable housing to a bending radius that is greater than a preset minimum bending radius to prevent any of (1) occlusion of a lumen inside the catheter, and (2) breakage of the catheter, due to bending of the catheter around the outer surface of the implantable housing.
