Custom Rectum Model

everyone gets a model in the end

The Challenge:

There are not very many stock anal fistula models available, none in fact. And procuring a cadaver with an anal fistula would be a long shot. So, our client; a medical device R&D engineer tasked with developing a device for treating fistulas, needed a reusable rectum model to iterate his device design while giving surgeons a way to test each iteration.


Model Design and Development:

Pulse MDM proposed an anus/rectum with fistulas where the anus/rectum presented permanently as if a rectal speculum was in use. The fistulas and surrounding tissue would be made to accept the implant procedure and the sutures required to secure the implant to surrounding healthy tissue. R&D engineers & surgeons would be able to suture the implant, examine their results, and remove the implant for another test. And we planned that eventually the model would be used as a training and education platform for colon and rectal surgery practitioners.


Model Benefit:

When is an anatomy model better than live tissue?

  • When your target requires a very specific pathology.
  • When you are early in the development cycle and want to quickly eliminate weaker solutions.
  • When you do not want to set up a logistically cumbersome lab in order to get fast feedback.
  • When removing variables and providing a consistent validation platform is beneficial to your testing protocol.
  • When repeatability is crucial when proving the efficacy of a device to the FDA.


If you are an R&D engineer, having your targeted anatomy in a cabinet near your desk that you can use to try each new prototype revision makes your job easier. It makes the development cycle progress much faster allowing for quick trial of each new iteration. We always design & create the consumable components to be as small as possible to keep the cost of use down and to make them easy to replace.

Anal Fistula Procedure Overview:

To treat anal fistulas, surgeons thread their fistula plug, which is like a pliant noodle, into the fistula inside the anus and pull it through to the outside. The fistula plug is flexible and dense. The surgeons suture the inside edge of the plug to the surrounding tissue after pulling it flush with the opening of the fistula in the anus/rectum.
