Identifying the worst case size for a product family is an important part of the validation process for implantable [...]]]> http://drperry.org/2009/identifying-worst-case-device-sizes/feed/ 0 Contact Interaction for Medical Implants http://drperry.org/2009/contact-interaction-for-medical-implants/ http://drperry.org/2009/contact-interaction-for-medical-implants/#comments Sat, 25 Apr 2009 07:05:11 +0000 kenperry http://drperry.org/?p=755 There are many circumstances when it is necessary to model contact and contact interactions when analyzing medical implants.  Such circumstances arise when devices interact with tooling, catheters, vessels and when self-contact occurs.  This latter situation arises for example when a stent is crimped down tightly to catheter dimensions.
