Abstract
A method for deploying an expandable implant in a body passage of varying diameter includes selecting a balloon having a radial dimension that varies, when the balloon is inflated, in accordance with the varying diameter of the body passage. The balloon is inserted, in a deflated state, into the body passage, with the expandable implant fitted radially around the balloon. The balloon is inflated so as to cause the implant to open, responsively to the varying radial dimension of the balloon, into an expanded shape that approximately matches the varying diameter of the body passage, thus anchoring the implant in the body passage.
Claims22
A method for deploying an expandable implant in a body passage of varying diameter, the method comprising:
- selecting a balloon having a radial dimension that varies, when the balloon is inflated, in accordance with the varying diameter of the body passage;
- inserting the balloon, in a deflated state, into the body passage comprising a coronary sinus, with the expandable implant fitted radially around the balloon;
- and
- inflating the balloon so as to cause the implant to open, responsively to the varying radial dimension of the balloon, into an expanded shape that approximately matches the varying diameter of the body passage, thus anchoring the implant in the body passage, wherein the expanded shape comprises a first end and a second end opposite the first end, the first end having a diameter that is larger than a diameter of the second end and a reduced diameter section therebetween, the reduced diameter section smaller than the diameter of the first end and the diameter of the second end.
Apparatus for treatment of a body passage of varying diameter, the apparatus comprising:
- a balloon, having a radial dimension that varies, when the balloon is inflated, in accordance with the varying diameter of the body passage, wherein the inflated balloon comprises a first end and a second end opposite the first end, the first end having a diameter that is larger than a diameter of the second end and a reduced diameter section therebetween, the reduced diameter section smaller than the diameter of the first end and the diameter of the second end;
- and
- an expandable implant, fitted radially around the balloon, so that when the balloon is inflated within the body passage, the implant opens, responsively to the varying radial dimension of the balloon, into an expanded shape that approximately matches the varying diameter of the body passage, thus anchoring the implant in the body passage.
