MEDICAL DEVICE, METHODS TO PRODUCE A CUTTING TOOL AND TO CREATE A CHANNEL WITH PREDETERMINATED GEOMETRY, AND, CUTTING TOOL

摘要

medical devices and methods for removing a predetermined shape of soft tissue from a target tissue layer are described, thereby leaving a matching channel with predetermined geometry and orientation in the target tissue layer. the medical device comprises elongated outer and inner coaxial members extending along the x-axis; said outer member comprises an open distal side and a first distal portion configured to adhere to said target tissue layer during forward axial movement; said inner member comprises a second distal part configured to rotate and project distally across said open distal side to cut said predetermined shape of the soft tissue from the target tissue layer and create said channel formed as a hole through the target tissue layer .
