Abstract

Presently, there is interest in making medical devices such as expandable stents and intravascular microactuators from shape memory polymer (SMP). One of the key challenges in realizing SMP medical devices is the implementation of a safe and effective method of thermally actuating various device geometries in vivo. A novel scheme of actuation by Curie-thermoregulated inductive heating is presented. Prototype medical devices made from SMP loaded with nickel zinc ferrite ferromagnetic particles were actuated in air by applying an alternating magnetic field to induce heating. Dynamic mechanical thermal analysis was performed on both the particle-loaded and neat SMP materials to assess the impact of the ferrite particles on the mechanical properties of the samples. Calorimetry was used to quantify the rate of heat generation as a function of particle size and volumetric loading of ferrite particles in the SMP. These tests demonstrated the feasibility of SMP actuation by inductive heating. Rapid and uniform heating was achieved in complex device geometries and particle loading up to 10% volume content did not interfere with the shape recovery of the SMP.

  • The magnetic-active SME makes selective heating of specific device areas of SMPCs possible.

    “In addition, the magnetic-active SME makes selective heating of specific device areas of SMPCs possible [35,142,337,377,378].”

    From A review of stimuli-responsive shape memory polymer composites (2013) · cites this paper as [142]

  • Major challenges for magnetically induced actuation are increase in inductive heating efficiency, applied frequencies should not exceed clinically usable window 50-100 kHz, and tailoring transition temperatures near body temperature for multi-shape polymers.

    “major challenges are still the increase in inductive heating efficiency [13,45] (the applied frequencies should not exceed the restrictive window of clinically usable frequencies (50-100 kHz) [216]), and in case of polymers with multi-shape capabilities the tailoring of transition temperatures in a region close to body temperature.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
