    Abstract: Implantable medical systems include implantable medical leads that have magnetic orientation-independent magnetically actuated switches that are placed in the conduction path to the electrode of the lead. Thus, regardless of the orientation of a substantial magnetic field like that from an MRI machine to the lead and switch within the lead, the switch opens when in the presence of that substantial magnetic field. The switch may be placed in close proximity to the electrode such that the opening of the switch disconnects the electrode from the majority of the conduction path which thereby produces a high impedance for RF current and reduces the amount of heating that may occur at the electrode when in the presence of substantial levels of RF electromagnetic energy as may occur within an MRI machine.

    Abstract: Implantable medical leads include a shield that is guarded at a termination by having a first portion and a second portion of the shield, where the first portion is between a termination of the shield at the second portion and an inner insulation layer that surrounds the filars. The first portion may reduce the coupling of RF energy from the termination of the shield at the second portion to the filars. The first and second portions may be part of a continuous shield, where the first and second portions are separated by an inversion of the shield. The first and second portions may instead be separate pieces. The first portion may be noninverted and reside between the termination at the second portion and the inner layers, or the first portion may be inverted to create first and second sub-portions. The shield termination at the second portion is between the first and second sub-portions.

    Abstract: Shields within implantable leads increase the torsional stiffness of the leads. The torsional stiffness may be reduced by cutting the shield axially to break the circumferential mechanical continuity of the shield. The circumferential shielding continuity of the shield may be re-established to preserve the shielding effect in various manners. The shield may overlap onto itself to close the slot created by the cut. A shield patch may be placed across the slot created by the cut. The shield may be located between two insulation layers of the lead. The shield may be cut and then the slot closed prior to application of the outer insulation layer. The outer insulation layer may then be added over the shield. The outer insulation layer may be compliant so that once covered, the circumferential mechanical continuity of the shield remains broken.

    Abstract: A bladder fullness level of a patient may be determined based on a frequency of mechanical oscillations of the bladder of the patient. The bladder may mechanically oscillate in response to the occurrence of non-micturition contractions of the bladder of the patient, which are contractions not associated with urine release. The frequency at which the bladder oscillates, e.g., following a non-micturition contraction, may have a correlation to the bladder fullness level. In some examples, a medical device may be configured to control the delivery of electrical stimulation therapy to the patient based on the oscillation frequency of the bladder. In addition, or instead to controlling therapy based on the oscillation frequency of the bladder, a notification, such as a patient or patient caretaker notification, may be generated (e.g., automatically by a processor of a device) based on the oscillation frequency of the bladder.
