Patent number: 11944317Abstract: An embodiment includes a system comprising: an outer conduit; a shape memory polymer (SMP) foam; a metal backbone including: (a)(i) a first portion that extends from the SMP foam proximal end to the SMP foam distal end and which is generally covered by the SMP foam, and (a)(ii) a distal portion that extends distally from the SMP foam distal end and which is not covered by the SMP foam; wherein: (b)(i) SMP foam and the metal backbone are both included within the outer conduit adjacent to the outer conduit distal end; (b)(ii) the metal backbone distal portion transitions from a secondary shape that is uncoiled to a primary shape that is coiled; and (b)(iii) the metal backbone distal portion is in the metal backbone distal portion secondary shape and is located between the SMP foam distal end and the distal end of the outer conduit.Type: GrantFiled: June 22, 2022Date of Patent: April 2, 2024Assignees: THE TEXAS A&M UNIVERSITY SYSTEM, SHAPE MEMORY MEDICAL, INC.Inventors: Duncan J. Maitland, Todd L. Landsman, Jennifer N. Rodriguez, Anthony J. Boyle, Alan C. Glowczwski, Mark A. Wierzbicki

Patent number: 10548608Abstract: An embodiment of the invention is a shape memory polymer (SMP) foam designed to recover its original shape through exposure to a solvent. Thermo-responsive SMPs are polymers designed to maintain a programmed secondary shape until heated above their transition temperature, upon which the polymer recovers its original, or primary, shape. The thermo-responsive SMP foam is programmed to its secondary shape prior to use, typically compression of the foam to a small volume, and remains in this programmed shape until exposed to a selected solvent such as dimethyl sulfoxide or ethyl alcohol. Upon exposure to the solvent, the transition temperature of the SMP foam decreases below the temperature of the environment and the SMP foam actuates to its primary shape. The SMP foam is tailored to actuate upon exposure to specific solvents while minimizing or preventing actuation when exposed to water or other solvents.Type: GrantFiled: June 7, 2016Date of Patent: February 4, 2020Assignee: Lawrenece Livermore National Security, LLCInventors: Anthony J. Boyle, Keith Hearon, Duncan J. Maitland, Landon D. Nash, Thomas S. Wilson
