Patent number: 10058689Abstract: Implantable drug delivery devices are provided to have a deployment shape for implantation in the body and a retention shape for retention in the body. The device may have one or more elongated drug reservoirs containing a drug, and the drug reservoir may be formed from a deformable material. In one case, a first filament is attached to the first end of the drug reservoir and second filament is attached to the second end of the drug reservoir, wherein a fastener is positioned about the first and second filaments to permit shortening and prevent lengthening of the filaments with reference to the ends of the drug reservoir, as a means for transforming the device from the implantation shape to the retention shape.Type: GrantFiled: February 29, 2016Date of Patent: August 28, 2018Assignee: TARIS Biomedical LLCInventors: Paul DiCesare, Jeffrey Radziunas, Andrew Barnes, Eric Britschock, David Sutton
