Subcutaneous implantation instrument with dissecting tool and method of construction
View Patent ↗A subcutaneous implantation instrument with dissecting tool and method of construction are described. An incising shaft longitudinally defines a substantially non-circular bore continuously formed to communicatively receive an implantable object and further includes a beveled cutting blade formed on a distal end. A dissecting tool includes a needle tip forming a pair of longitudinal cutting edges progressively defined outwardly from the needle tip planar to the beveled cutting blade and removably affixable to the distal end of the incising shaft through a proximal coupling. A delivery mechanism longitudinally defines a substantially non-circular bore formed to deploy the implantable object into the incising shaft. One goal is to reduce the subcutaneous sensor insertion of implantable objects and devices, such as sensors, having non-conforming shapes to be the functional equivalent of an injection.
