Catheter with controlled lumen recovery
First Claim
1. An implantable medical device, comprising:
- a body including a lumen extending therethrough; and
at least one activatable element disposed within the body, a dimension of each of the at least one activatable elements changing in response to a predetermined stimulation between an activated state and an inactivate state to change a shape of the body to control a degree of opening of the lumen.

Abstract
An implantable medical device, comprising a body including a lumen extending therethrough at least one activatable element disposed within the body, a dimension of each of the at least one activatable elements changing in response to a predetermined stimulation between an activated state and an inactivate state to change a shape of the body to control a degree of opening of the lumen and at least one actuation element, each of the at least one actuation elements being configured to selectively supply the predetermined stimulation to a corresponding one of the at least one activatable elements to move the corresponding one of the at least one activatable elements between the activated and inactive states.

17. A catheter comprising;
-
an elongated body defining a lumen;
a polymeric material forming a wall of the elongated body; and
a plurality of activatable material elements a size of which, when subjected to a predetermined stimulation, changes from an inactive state to an activated state, the activatable material elements being coupled to the wall in a pattern selected so that, when placed in the activated state, the activatable material elements draw the wall into a predetermined shape to control an opening of the lumen. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
