Abstract
Specified information can be provided to a user, to a machine, or to an automated process using a specified configuration of a plurality of radiopaque rings about at least a portion of an implantable lead.
Claims17
A system comprising:
- an implantable lead including:
- a plurality of radiopaque rings arranged in a specified configuration about a portion of the implantable lead;
- and
- wherein the specified configuration of the plurality of radiopaque rings is configured to provide specified information to a user, to a machine, or to an automated process;
- and
- wherein the specified configuration is selected from a first specified configuration of the plurality of radiopaque rings that is configured to provide an indication that the implantable lead is MR compatible to a first magnetic field strength, and a second specified configuration that is configured to provide an indication that the implantable lead is MR compatible to a second magnetic field strength, the second specified configuration different than the first specified configuration and the second magnetic field strength different than the first magnetic field strength.
3 more elements
A system comprising:
- an implantable lead including:
- a rear seal configured to be at least inserted into a lead port of an implantable medical device (IMD) header;
- and
- a plurality of radiopaque rings each having different inner diameters arranged in a specified configuration about a portion of the implantable lead, wherein the plurality of radiopaque rings are configured to be injection molded into the rear seal;
- and
- wherein the specified configuration of the plurality of radiopaque rings provides an indication of a level of magnetic resonance (MR) compatibility of the implantable lead;
- wherein a first specified configuration is configured to provide an indication that the implantable lead is MR Conditional to a first magnetic field strength and a second specified configuration is configured to provide an indication the implantable lead is MR Conditional to a second magnetic field strength, the second specified configuration different than the first specified configuration and the second magnetic field strength different than the first magnetic field strength;
- and
- wherein the first specified configuration includes a first number of radiopaque rings and the second specified configuration includes a second number of radiopaque rings, the second number different than the first number.
6 more elements
A system comprising:
- an implantable medical device;
- and
- an implantable lead, configured to be coupled to the implantable medical device, including:
- a rear seal configured to be at least partially inserted into a lead port of a header of the implantable medical device;
- and
- a plurality of radiopaque rings, each ring having a ring characteristic, wherein the plurality of radiopaque rings are configured to be injection molded into the rear seal in a specified configuration about a portion of the implantable lead;
- wherein a first specified configuration of the plurality of radiopaque rings indicates that the implantable lead is MR compatible to a first magnetic field strength;
- wherein a second specified configuration of the plurality of radiopaque rings indicates that the implantable lead is MR compatible to a different second magnetic field strength;
- and
- wherein each ring of the plurality of radiopaque rings includes at least one different ring characteristic selected from the group consisting of a radiopaque ring shape, a radiopaque ring inner or outer diameter, and a spacing from an adjacent radiopaque ring.
