Abstract

Methods and apparatuses relate to an implantable apparatu0s that may be used to apply tensile force(s) to one or more tissue regions (e.g., proximal and distal esophagus portions, bowel, other conduits) within the body. Such tensile force(s) may cause stretch and/or growth of the tissue region(s). In various embodiments, support members (e.g., suture rings) may be attached to respective tissue regions. The support members may accommodate attachment of a number of sutures along the tissue region. Upon suitable attachment of the support member(s) to the tissue region(s), the actuator may be coupled to the support member(s). The actuator may then be controlled so as to cause relative movement between the support members toward or away from one another. Such movement may result in the application of appropriate tensile force(s) to the tissue region(s).

Claims25

Dependent claims

An implantable apparatus for applying force to bodily tissue, comprising:

an actuator having a first anchor portion and a second anchor portion, the actuator configured to cause relative movement of the first anchor portion and the second anchor portion toward or away from one another;
a first support member constructed to be attached to a first tissue region and adapted to be coupled to the first anchor portion of the actuator;
and
a second support member constructed to be attached to a second tissue region and adapted to be coupled to the second anchor portion of the actuator, wherein relative movement of the first anchor portion and the second anchor portion toward or away from one another results in application of a tensile force to at least one of the first tissue region and the second tissue region, the first and second tissue regions are exterior portions of a tissue conduit, the first and second support members are constructed to be attached around at least a portion of a circumference of the tissue conduit, and the actuator is configured to be positioned outside of the tissue conduit during use.
