Design and fabrication of a low cost implantable bladder pressure monitor

Abstract

Abstract-In the frame of the Flemish Community funded project Bioflex we developed and fabricated an implant for short term bladder pressure monitoring, and diagnosis of incontinence. This implant is soft and flexible to prevent damaging the bladder's inner wall, and designed for a 7 days long implantation. It is based on a standard flexible electronic circuit connected to a battery, embedded in silicone, of which the surface is treated to enhance the biocompatibility and to prevent salt deposition. This article describes the fabrication of the pill. The implantation and the result of the in-vivo experimentation will be presented in another article.

Implanted, inductively-coupled, radiofrequency coils fabricated on flexible polymeric material: Application to in vivo rat brain MRI at 7T

“…PDMS is easy to handle and widely considered as biocompatible for short term (7 days) of implantation [55,56]. PDMS Sylgard Ò 184 was provided by Dow Corning Corporation (Midland, MI, USA).…”

The BladderPill: An in-body system logging bladder pressure

“…After soldering the components in a reflow oven, embedding into silicone followed as described in Ref. [20]. These samples, one of which is shown in Fig.…”

“…Moulding was done as described in Ref [20]. by the Centre for Microsystems and Technology Gent, Belgium.…”

Design and fabrication of implantable pressure sensing resistor sensor for human bladder monitoring system

“…However, there has been little progress in the implantable sensor for the human/animal bladder. Micro sensors for the measurement of blood pressure and for intraocular pressure have been developed (Fonseca et al 2006;Axisa et al 2009). The pressure sensor for bladder has been studied by F. Axia group (Axisa et al 2009).…”

Axia group (Axisa et al 2009). However, it had much difficulty in real time monitoring continuously for a long time because it was an implantable type of catheter with a large battery.…”
