APPARATUS AND METHODS FOR DETACHING AN EXPANDABLE MEMBER FROM A MEDICAL DEVICE
First Claim
1. An apparatus, comprising:
- a shaft having a proximal end portion and a distal end portion;
an expandable member configured to move between a collapsed configuration and an expanded configuration, the expandable member being coupled to the distal end portion of the shaft and being configured to receive a medicament therein;
a sleeve coupled to the distal end portion of the shaft and configured to move relative to the shaft between a first position and a second position, the sleeve being configured to be disposed about the expandable member when the sleeve is in the first position and disposed apart from the expandable member when the sleeve is in the second position; and
a detachment mechanism coupled to the distal end portion of the shaft, the detachment mechanism configured to detach the expandable member from the shaft when the sleeve is in the second position.

Abstract
A medical implant device includes a shaft, an expandable member coupled to the distal end portion of the shaft, a sleeve and a detachment mechanism. The expandable member is configured to move between a collapsed configuration and an expanded configuration, and can be used to deliver a medicament, a therapeutic substance and/or a structural member into the body. The sleeve is coupled to the distal end portion of the shaft, and is configured to move relative to the shaft between a first position and a second position. The sleeve is configured to be disposed about the expandable member when in the first position and disposed apart from the expandable member when in the second position. The detachment mechanism is coupled to the distal end portion of the shaft, and is configured to detach the expandable member from the shaft when the sleeve is in the second position.

16. A method, comprising:
-
inserting into a bodily tissue of a body an expandable member defining a selectively releasable opening; conveying a medicament into the expandable member via a shaft coupled to the expandable member to at least partially fill the expandable member; allowing the medicament to at least partially solidify within the expandable member; detaching the expandable member from the shaft; and removing the shaft from the body. - View Dependent Claims (17, 18, 19, 20, 21)

22. A method, comprising:
-
inserting into a vertebra of a body an expandable member defining a selectively releasable opening; conveying a first volume of a medicament into the expandable member via a shaft coupled to the expandable member to at least partially fill the expandable member; actuating the selectively releasable opening such that a portion of the medicament is conveyed from the expandable member into the vertebra; conveying a second volume of the medicament into the expandable member via the shaft; detaching the expandable member from the shaft; and removing the shaft from the body. - View Dependent Claims (23, 24, 25)

30. A method, comprising:
-
inserting into a vertebra of a body an expandable member defining a separable portion; conveying a first volume of a medicament into the expandable member via a shaft coupled to the expandable member to at least partially fill the expandable member; actuating the separable portion to define an opening; conveying a second volume of the medicament into the expandable member via the shaft such that a first portion of the medicament is conveyed from the expandable member into contact with a bodily tissue within the vertebra; moving the expandable member proximally a first distance within the vertebra; conveying a third volume of the medicament into the expandable member via the shaft such that a second portion of the medicament is conveyed from the expandable member into contact with the bodily tissue within the vertebra; moving the expandable member proximally a second distance within the vertebra; conveying a fourth volume of the medicament into the expandable member via the shaft such that a third portion of the medicament is conveyed from the expandable member into contact with the bodily tissue within the vertebra; detaching the expandable member from the shaft; and removing the shaft from the body. - View Dependent Claims (31, 32, 33)

34. A method, comprising:
-
inserting into a vertebra an expandable member defining a selectively releasable opening; conveying a first volume of a first medicament into the expandable member via a shaft coupled to the expandable member to at least partially fill the expandable member; actuating the selectively releasable opening; moving the expandable member proximally a first distance within the vertebra; conveying a second volume of a second medicament into the expandable member via the shaft; and removing the expandable member from the vertebra.
