Area of Science:

  • Biomedical Engineering
  • Urology
  • Materials Science

Background:

  • Detrusor underactivity (DU) significantly impacts bladder function, leading to incomplete voiding and serious health concerns.
  • Current treatments for DU are limited, necessitating innovative therapeutic approaches.
  • Restoring bladder contractility is crucial for managing DU and improving patient quality of life.

Purpose of the Study:

  • To introduce a novel, 3D-printed, implantable device for treating detrusor underactivity.
  • To evaluate the efficacy and safety of a shape memory alloy (SMA)-actuated device in a preclinical model.
  • To demonstrate the potential of physical bladder contraction for restoring voluntary bladder control.

Main Methods:

  • Development of a flexible, 3D-printed implantable device utilizing SMA actuators.
  • Benchtop experiments using a rubber balloon model to simulate bladder voiding and assess device function.
  • In vivo testing of the device in anesthetized rats to evaluate performance and safety at operating temperatures.

Main Results:

  • The SMA-actuated device successfully induced bladder contraction and achieved a voiding volume of over 8% in a rat model.
  • Operating temperatures of the SMA actuators were confirmed to be safe for eventual implantation.
  • The device facilitated voiding without requiring surgical intervention or pharmacological sphincter relaxation.

Conclusions:

  • The presented SMA-actuated implantable device shows significant promise as a novel therapeutic option for detrusor underactivity.
  • This approach offers a new paradigm for treating bladder dysfunction by physically augmenting bladder contractility.
  • Further research and development could lead to a viable clinical solution for individuals suffering from DU.
