Abstract: Embodiments herein relate to medical devices and methods for using the same to treat cancerous tumors within a bodily tissue. A medical device system herein can include an electric field generating circuit configured to generate one or more electric fields, and control circuitry. The system can include one or more electrodes disposed on a first stimulation lead to deliver the electric fields to a site of a cancerous tumor within a patient and one or more electrodes disposed on a second stimulation lead to deliver the electric fields to the site of a cancerous tumor within a patient. The first and second stimulation leads can be configured to be implanted on or about a duodenum. The electric field generating circuit can generate electric fields at frequencies selected from a range of between 10 kHz to 1 MHz. Other embodiments are also included herein.

Abstract: Implantable devices formed of materials which are not readily imageable, and which may shift from a delivery configuration to a deployment configuration upon deployment, are delivered and deployed with a deployment/delivery device having sensors generating a signal indicating contact of the delivery/deployment device with tissue to guarantee purchase of the implantable device with tissue upon deployment. The implantable device may be a tissue anchor with talons which shift from a delivery configuration to a deployed configuration. The sensors may be positioned along a distal end of the delivery/deployment device to indicate purchase of the device with tissue, to ensure purchase of the talons with tissue upon deployment. The sensors may include at least three sensors, which may be spaced apart from one another, to indicate full contact of the distal end of the delivery/deployment device with tissue. The sensors may optionally be aligned with the talons.

Abstract: Implantable devices formed of materials which are not readily imageable are delivered and deployed with a deployment/delivery device having one or more sensors generating a signal indicating a condition of the implantable device relative to the deployment site. For instance, the signal indicates at least one or more of the following: purchase of the implantable device with tissue, level of purchase of the implantable device with tissue, the position of the implantable device relative to the deployment site, seating of tissue with respect to the implantable device, extent of contact of the implantable device with tissue, or further information about the implantable device and/or the delivery/deployment device. As such, the implantable device need not be imaged to determine the relationship of the implantable device relative to the deployment site.
