Custom Training Models for Sutures

make your demo as innovative as the product you are selling

The Challenge:

Create a dynamic realistic feeling skin that can be sutured and then stretched to show how the barbed sutures stay in place when cut. And design a model that sales reps can give surgeons hands-on experience with the product anywhere.


Model Design and Development:

Pulse MDM designed a tissue plate fixture that capitalized on the flexible properties of polypropylene. Without complicated hinges or knobs to turn endlessly, a simple bending mechanism increases the tension of the tissue plate. The skin & tissue plate can be placed under three levels of tension. At it takes seconds to increase the tension, surgeons can practice suturing and putting the incision under pressure, and it takes a minute to replace the skin/tissue plate. The fixture itself was shaped to match the product logo, reinforcing the brand.  Several prototypes were developed and tested by the client to achieve a synthetic skin that captured the suture barbs like live tissue.


Model Solution:

A custom tissue tensioner with reinforced real-feel skin/fascia was created so that surgeons could suture an incision, put the incision under increasing tension, and then snip the sutures to see how they still held the incision closed. A new tissue plate can be inserted quickly, giving each surgeon a fresh try. Salespeople love the model as it easily collapses flat to fit into a briefcase.


Although this custom model is not available for sale to the public, we are delighted to make you a version that is specific to your unique medical device and procedure. Please use this link to start the process of receiving a model concept; a visual representation of how clinicians and patients will experience your product and procedure. Pulse MDM does not charge for model concepts or the conversations around them so there is no risk to see how we can help you to tell your story in the most engaging and memorable way possible.

Custom Models for Suture Training

Barbed Suture Procedure Overview:

Barbed sutures offer consistent tension control and approximation during the closure.  The anchor design delivers multiple points of fixation that help maintain approximation along the suture line during the closure.

A barbed suture has the advantage of the elimination of suture knots, which can create an opportunity for infection and place ischemic demands on the tissue. They offer the strength & security of interrupted closure, but without knots. More efficient than continuous or interrupted suturing barbed sutures are more efficient because they eliminate the need for an assistant to follow the suture line (no need to hold the tension after each bite) and they allow for potentially less time under anesthesia.
