摘要： A device for implantation in the vasculature of a patient can include a fixation mechanism for anchoring the device in place while allowing for easy removal of the device. The fixation mechanism can include a detachable and/or biodegradable portion that can allow for removal from the bulk of the device in order to allow for the bulk to simply be pulled from the body without likelihood of injury. These devices also can include electrode assemblies that do not promote fibrous ingrowth, further reducing the likelihood for injury upon extraction of the device.

摘要： An artificial intervertebral disc and disc nucleus are described herein having chambers and dampening members. The dampening members may be within or outside of the main body of the device. The chambers may be filled with a suitable liquid, gas, or both, and separated by valves to regulate flow of fluid between chambers, within a dampening member, between the main body and dampening member, or all of the above. Chambers may be filled with responsive hydrogels, EPAM, or other suitable materials, and the device may have activation plates or members, a strain gauge, a pressure sensor, or other means for detecting changes in the materials and/or triggering desired changes in the materials in order to mimic the behavior of a healthy native disc or disc nucleus. A control system may be in communication with the device for receiving feedback and delivering stimuli to initiate desired changes in the fluids or other materials. Membranes may be of variable permeability and may be metallized to ensure as low permeability as possible. Dampening members may be filled during manufacture with carbon dioxide or other suitable gas which may be in a supercritical state and allowed to return to ambient temperature and gaseous state or by other means. Methods of manufacture, delivery of the artificial disc and related structures, and methods of treatment are also described.

摘要： An energy harvesting device positionable within a blood vessel for use in generating energy for powering all or a portion of the functions of a diagnostic or therapeutic medical implant. The energy harvesting device includes piezoelectric elements arranged to generate a voltage in response to mechanical blood vessel activity such as bending, expansion or contraction of the blood vessel, or flow of blood through the blood vessel. The electrical energy generated by the piezoelectric elements may be used to recharge a battery, stored in a capacitor, and/or used in real time to generate the energy used for operation of the implant.

摘要： The present application describes an intravascular implantable pacing and/or defibrillation system. The described system includes a pulse generator that is implantable within a blood vessel and proportioned to blood flow through the blood vessel, and at least one electrode attachable to the pulse generator. During implantation, the pulse generator is introduced into a patient's vasculature, advanced to a desired vessel and anchored in place within the vessel. The electrode or electrodes are placed within the heart or surrounding vessels as needed to deliver electrical pulses to the appropriate location.
