Abstract:
The disclosure relates in some aspects to an implantable pressure sensor and a method of measuring pressure. In some embodiments pressure may be measured through the use of an implantable lead incorporating one or more pressure sensors. In some aspects a pressure sensor is implemented in a micro-electromechanical system (“MEMS”) that employs direct mechanical sensing. A biocompatible material is attached to one or more portions of the MEMS sensor to facilitate implant in a body of a patient. The MEMS sensor may thus be incorporated into an implantable lead for measuring blood pressure in, for example, one or more chambers of the patient's heart.
Abstract:
A biocompatible inductor for an implantable medical lead is disclosed herein. In one embodiment the biocompatible inductor may include a biocompatible bobbin and a wire wound about a barrel of the biocompatible bobbin to form a coil. The wire may include an electrically conductive core, an electrically conductive biocompatible jacket extending over the core, and a coating of high dielectric strength insulation material extending over the jacket. Additionally, the biocompatible inductor may include medical adhesive located in gaps within the coil and a polyester shrink tube covering the coil.
Abstract:
An implantable medical lead configured for improved MRI safety and heating reduction performance is disclosed herein. In one embodiment, the lead includes a tubular body having a proximal end and a distal end with a lead connector near the proximal end. In this embodiment the lead further includes a conductor extending longitudinally within the tubular body and having a proximal end that is electrically coupled to the connector and a distal end electrically coupled to a contact pin. The lead in this embodiment further includes a filter element electrically coupled to a distal end of the contact pin and a flange electrically coupled between a proximal end of the filter element and a proximal portion of an electrode. In this embodiment the flange and the proximal portion of the electrode form at least a first part of a hermetic chamber enclosing the filter element.
