Abstract
Embodiments regard innovations for implantable electrostimulation devices and corresponding systems that operate using or contain the implantable electrostimulation devices. A system can include an implantable electrostimulation device. The system can further include an introducer configured to deliver the electrostimulation device to a target location inside a patient body. The introducer can comprise a migration mitigation component configured to couple with the electrostimulation device.
Claims13
A system comprising:
- an implantable electrostimulation device;
- and
- an introducer including an inner sidewall that defines a lumen extending through the introducer, the introducer configured to receive the implantable electrostimulation device in a proximal end of the lumen and deliver the electrostimulation device to a target location inside a patient body at a distal portion of the lumen, wherein the introducer comprises a migration mitigation component integrally formed with the introducer, in a distal portion of the introducer, and including the lumen extending therethrough, the migration mitigation component i) configured to directly mechanically connect with an outer surface of the electrostimulation device and arrest travel of the electrostimulation device through a distal end of the distal portion of the introducer and (ii) is longitudinally contractible and an outer diameter of at least a portion of the migration mitigation component is configured to increase in response to longitudinal contraction of the migration mitigation component.
A system comprising:
- an implantable electrostimulation device comprising a frustoconical outer wall portion;
- and
- an introducer including an inner sidewall that defines a lumen extending through the introducer, the introducer configured to receive the implantable electrostimulation device in a proximal end of the lumen and deliver the electrostimulation device to a target location inside a patient body at a distal portion of the lumen, wherein the introducer comprises a migration mitigation component integrally formed with the introducer, in a distal portion of the introducer, and including the lumen extending therethrough, the migration mitigation component configured to directly mechanically connect with an outer surface of the electrostimulation device and arrest travel of the electrostimulation device through a distal end of the distal portion of the introducer, and the migration mitigation component comprises a frustoconical inner wall portion, the inner wall portion of the migration mitigation component is configured to couple with the outer wall portion of the electrostimulation device when the migration mitigation component arrests travel of the electrostimulation device through the distal end of the introducer.
