A Geometrically Transient Platform for Bioelectronic Implants

Advanced Materials, EarlyView.
Minimally invasive bioelectronic implants often compromise performance for smaller sizes. To resolve this optimization dilemma, a wireless bioelectronic implant with a transient geometry is introduced (MiFi). The origami‐inspired device miniaturizes up to sixfold for syringe insertion and autonomously unfolds post‐implantation.

Alfentanil in an anaesthetic technique for penetrating eye injuries [PDF]

Anaesthesia, 1986
Summary Alfentanil in three doses (10, 20 and 30 μ/kg)was added to an anaesthetic technique suitable far penetrating eye injuries. All three doses proved effective in abolishing the marked present response to tracheal intubation which occurs with this technique, but at least 20 μg/kg was needed to obtund the heart rate response ...
