Patent number: 11642438Abstract: Embodiments of the invention provide compositions including bio degradable polymers, medical implants fabricated from these compositions and methods of using such implants. Many embodiments provide medical implants comprising a first polymer backbone having a first rate of biodegradation and a second polymer backbone having a second rate of biodegradation faster than the first rate. In some embodiments, the second backbone is configured to be replaced by a natural tissue layer. The first backbone provides a scaffold for the implant while the second backbone degrades. This scaffold can enhance mechanical properties of the implant including various aspects of mechanical strength such as tensile, bending, hoop and yield strength; and elasticity. The scaffold also serves to maintain a minimum level of structural support of the implant during the period of degradation of the second backbone or for the entire life of the implant so that the implant does not mechanically fail.Type: GrantFiled: July 13, 2018Date of Patent: May 9, 2023Assignee: InCube Labs, LLCInventors: Mir Imran, Sanjay Patel, Joel Harris

Patent number: 11590049Abstract: The present invention relates to a movement-dependent stabilisation support system (100) for stabilising a moving body (200), which comprises a plurality of sensors (110), a plurality of actuators (120) and a control unit (130). The plurality of sensors (110) continuously detects movement parameters of the body (200), on which basis the control unit (130) determines whether there is an instability of the body (200). If it is determined that there is an instability, the control unit (130) selects a stabilisation strategy, according to which the actuators (120) are controlled. When controlled, the actuators (120) attached to the body (200) stiffen and limit the freedom of movement of the body (200), such that a movement in the direction of the imminent unstable state is prevented or suppressed. In this way, the body (200) is supported in its stabilisation and an imminent fall is prevented.Type: GrantFiled: July 9, 2020Date of Patent: February 28, 2023Inventors: Elvira Kuhn, Feodor Kusmartsev
