| 20100137945 | AUTOMATED VERIFICATION OF MRI COMPATIBILITY OF ACTIVE IMPLANTABLE MEDICAL DEVICE - A system may include a processor configured to automatically obtain magnetic resonance imaging compatibility information relating to compatibility of an active implantable medical device implantable in a patient with an MRI modality from at least two information sources. The processor may also be configured to automatically determine compatibility of the active implantable medical device with the magnetic resonance imaging modality based on the magnetic resonance imaging compatibility information. | 06-03-2010 |
| 20100137946 | PATIENT-CENTRIC DATA COLLECTION FOR AUTOMATED MRI COMPATIBILITY VERIFICATION - A system may include a patient information terminal that receives magnetic resonance imaging compatibility information from a patient and a processor that automatically determines compatibility of an active implantable medical device with an magnetic resonance imaging modality based on the magnetic resonance imaging compatibility information. The magnetic resonance imaging compatibility information includes information relating to compatibility of the active implantable medical device implantable in the patient and the magnetic resonance imaging modality. | 06-03-2010 |
| 20100137947 | PATIENT PROGRAMMER WITH AUTOMATED MRI COMPATIBILITY VERIFICATION FOR ACTIVE IMPLANTABLE MEDICAL DEVICE - A system may include an active implantable medical device implantable in a body of a patient and a patient programmer for the AIMD. The patient programmer may be configured to obtain magnetic resonance imaging (MRI) compatibility information relating to compatibility of the AIMD with an MRI modality. | 06-03-2010 |
| 20120035616 | STEERING AN IMPLANTABLE MEDICAL LEAD VIA A ROTATIONAL COUPLING TO A STYLET - An implantable medical lead has a torsional stiffness and is rotationally coupled to a stylet. Applying rotation directly to the lead in turn causes rotation of the stylet. Where the stylet has a bent tip for purposes of steering the lead, the rotation applied to the lead rotates the bent tip so that the lead can be steered by rotating the lead rather than rotating a hub of the stylet. The rotational coupling may be achieved through one or more features provided for the lead and/or the stylet, such as a feature within a lumen of the lead that mates to a feature along the stylet or a feature of the stylet hub that engages the proximal end of the lead. The torsional stiffness of the lead may be provided by adding a feature within the lead body, such as a braided metal wire or an overlapping foil. | 02-09-2012 |
| 20120035695 | GROUNDING OF A SHIELD WITHIN AN IMPLANTABLE MEDICAL LEAD - Grounding of a shield that is located in an implantable medical lead may be done in many ways. The ground pathway may couple to the shield at a point that is outside of a header of an implantable medical device to which the implantable medical lead is attached. The ground pathway may couple to the shield at a point that is within the header of the implantable medical device. The ground pathway may terminate at the metal can of the implantable medical device. As another option, the ground pathway may terminate at a ground plate that is mounted to the header. The ground pathway may be direct current coupled from the shield to the can or ground plate. Alternatively, the ground pathway may include one or more capacitive couplings that provide a pathway for induced radio frequency current. | 02-09-2012 |
| 20120035696 | TERMINATION OF A SHIELD WITHIN AN IMPLANTABLE MEDICAL LEAD - A shield located within an implantable medical lead may be terminated in various ways. The shield may be terminated by butt, scarf, lap, or other joints between insulation layers surrounding the lead and an insulation extension. For lap joints, a portion of an outer insulation layer may be removed and a replacement outer insulation layer is positioned in place of the removed outer insulation layer, where the replacement layer extends beyond an inner insulation layer and the shield. The replacement layer may also lap onto a portion of the insulation extension. Barbs may be located between the replacement layer and the inner insulation layer or the insulation extension. The shield wires have ends at the termination point that may be folded over individually or may be capped with a ring located within one of the insulation layers of the jacket. | 02-09-2012 |
