Abstract

A device includes an outer member extending between a first end and a second end. The outer member comprises an inner surface defining a passage. The device includes an inflatable member having a first end extending from the second end of the outer member and a second end. The inflatable member includes an inner surface defining a chamber. The inner surface of the outer member is continuous with the inner surface of the inflatable member. The device includes an inner member having a first end positioned within the passage and a second end coupled to the second end of the inflatable member such that the inner member does not engage the inner surface of the outer member. Systems and methods are disclosed.

Claims19

Dependent claims

A method comprising:

providing a device comprising an expandable first tubing portion, an expandable second tubing portion, a transition portion, and a substantially rigid outer member, the first tubing portion and the second tubing portion being joined by the transition portion, the first tubing portion extending through a first passage extending through the substantially rigid outer member, and the second tubing portion extending outwardly from the substantially rigid outer member;
creating an access path to a bone;
inserting the device into the access path to position at least a first inflatable lobe portion and a second inflatable lobe portion of the second tubing portion within the bone;
passing an inflation medium through a second passage formed by an inner surface of the first tubing portion, through a third passage formed by an inner surface of the transition portion, and into a chamber formed by an inner surface of the second tubing portion, the inner surfaces of the first tubing portion, the transition portion, and the second tubing portion being continuous with one another;
preventing the first tubing portion from expanding via contact of an outer surface of the first tubing portion with an inner surface of the substantially rigid outer member;
inflating the first inflatable lobe portion and the second inflatable lobe portion of the second tubing portion from uninflated positions to inflated positions with the inflation medium by expanding the first inflatable lobe portion and the second inflatable lobe portion;
and
compressing a portion of the bone and create a cavity via inflation of the first inflatable lobe portion and the second inflatable lobe portion.

inserting the device into the access path to position at least a first inflatable lobe portion and a second inflatable lobe portion of the second tubing portion within the bone;
passing an inflation medium through a second passage formed by an inner surface of the first tubing portion, through a third passage formed by an inner surface of the transition portion, and into a chamber formed by an inner surface of the second tubing portion, the inner surfaces of the first tubing portion, the transition portion, and the second tubing portion being continuous with one another;
preventing the first tubing portion from expanding via contact of an outer surface of the first tubing portion with an inner surface of the substantially rigid outer member;
inflating the first inflatable lobe portion and the second inflatable lobe portion of the second tubing portion from uninflated positions to inflated positions by expanding the first inflatable lobe portion and the second inflatable lobe portion with the inflation medium, while simultaneously limiting inflation of the transition portion in comparison to the first inflatable lobe portion and the second inflatable lobe portion, the first inflatable lobe portion and the second inflatable lobe portion having diameters substantially equal to one another and greater than a diameter of the transition portion;
and
compressing a portion of the bone and create a cavity via inflation of the first inflatable lobe portion and the second inflatable lobe portion.

A method comprising:

providing a device comprising:
a substantially rigid outer member having a proximal first end, an opposite distal second end, and a first passage extending between the proximal first end and the distal second end,
an inner member having a first end and an opposite second end;
an expandable first tubing portion having a proximal first end and an opposite distal second end, the first tubing portion comprising an outer surface and an inner surface, the first tubing portion extending through the first passage, and the inner surface of the first tubing portion defining a second passage;
an expandable second tubing portion having a proximal first end and a distal second end, the second tubing portion including a first inflatable lobe portion, a second inflatable lobe portion, and connecting portion connecting the first inflatable lobe portion and the second inflatable lobe portion, and an inner surface defining a chamber within the first inflatable lobe portion, the second inflatable lobe portion, and the connecting portion;
a transition portion connecting the first tubing portion and the second tubing portion, the transition portion including an inner surface being continuous with the inner surface of the first tubing portion and the inner surface of the second tubing portion;
creating an access path to a bone;
inserting the device into the access path to position at least the first inflatable lobe portion and the second inflatable lobe portion of the second tubing portion within the bone;
inflating at least the first inflatable lobe portion and the second inflatable lobe portion of the second tubing portion from uninflated positions to inflated positions;
and
compressing a portion of the bone and create a cavity via inflation of the first inflatable lobe portion and the second inflatable lobe portion,
wherein the substantially rigid outer member prevents expansion of the first tubing portion during inflation of the first inflatable lobe portion and the second inflatable lobe portion, and the first end of the inner member is positioned within the first passage and the second end of the inner member is connected to the distal second end of the second tubing portion such that the inner member does not engage the inner surface of the first lubing portion.
