Lumen-traveling biological interface device and method of use
First Claim
Patent Images
1. A method of emplacing a cardiac stimulation device, comprising:
- causing a self-propelling cardiac stimulation device to travel within a body tube tree of a subject toward a target site;
pushing or pulling one or more additional cardiac stimulation devices with the self-propelling cardiac stimulation device;
if a branch point including two or more branches within the body tube tree is reached by the self-propelling cardiac stimulation device, causing the self-propelling cardiac stimulation device to enter a branch leading toward the target site;
causing the self-propelling cardiac stimulation device to stop traveling upon reaching the target site; and
delivering a cardiac pacing stimulus at the target site.

Abstract
Lumen-traveling biological interface devices and associated methods and systems are described. Lumen-traveling biological interface devices capable of traveling within a body lumen may include a propelling mechanism to produce movement of the lumen-traveling device within the lumen, electrodes or other electromagnetic transducers for detecting biological signals and electrodes, coils or other electromagnetic transducers for delivering electromagnetic stimuli to stimulus responsive tissues. Lumen-traveling biological interface devices may also include additional components such as sensors, an active portion, and/or control circuitry.

11. A method of emplacing a cardiac stimulation device, comprising:
-
selecting a self-propelling cardiac stimulation device sized to fit within a target site from an assortment of self-propelling cardiac stimulation devices of different sizes; causing the self-propelling cardiac stimulation device to travel within a body tube tree of a subject toward a target site; if a branch point including two or more branches within the body tube tree is reached by the self-propelling cardiac stimulation device, causing the self-propelling cardiac stimulation device to enter a branch leading toward the target site; causing the self-propelling cardiac stimulation device to stop traveling upon reaching the target site and delivering a cardiac pacing stimulus at the target site. - View Dependent Claims (12, 13, 14, 15, 16, 17)
