1. A balloon catheter comprising:
- a catheter extending between opposite proximal and distal ends, the catheter comprising an inner surface defining a lumen, the distal end comprising an opening that is in communication with the lumen, the proximal end comprising a valve, the valve including a membrane;
a balloon having a distal end coupled to the distal end of the catheter such that a distal end surface of the balloon is flush with a distal end surface of the catheter; and
a stylet extending through the membrane such that the stylet is removably disposed in the lumen to provide strength to the catheter, the stylet having a length that prevents a distal tip of the stylet from being positioned distal to the distal end surface of the balloon,wherein the stylet has a maximum diameter that is less than that of the lumen and the opening such that a material in the lumen may be passed around the stylet and exit the lumen through the opening.

Abstract
A surgical system and method for correction of a bone injury or disorder are provided. The device includes an elongated shaft that extends between a proximal end and a distal end and defining an interior lumen. A valve disposed with the proximal end of the elongated shaft and including a membrane. An inflatable structure is coupled to the distal end of the elongated shaft. A stylet is configured for insertion through the membrane and is removably disposed in the interior lumen of the elongated shaft such that the stylet provides strength to the elongated shaft.

14. A balloon catheter comprising:
-
a catheter extending between opposite proximal and distal ends, the catheter comprising an inner surface defining a lumen, the distal end comprising an opening that is in communication with the lumen, the proximal end comprising a valve, the valve including a membrane constructed from a resealable material; a balloon comprising a distal end that is coupled to the distal end of the catheter such that a distal end surface of the balloon is flush with a distal end surface of the catheter; and a stylet extending through the membrane such that the stylet is removably disposed in the lumen to provide strength to the catheter, the stylet having a length that prevents a distal tip of the stylet from being positioned distal to the distal end surface of the balloon, wherein the catheter comprises a port that is continuous with the lumen such that a material can be moved through the port and into an interior volume of the balloon to inflate the balloon, wherein the stylet has a maximum diameter that is less than that of the lumen and the opening such that a material in the lumen may be passed around the stylet and exit the lumen through the opening.

15. A method comprising:
-
inserting a cannula into a patient; inserting a catheter through the cannula such that a balloon is positioned within the patient, a distal end of the balloon being coupled to a distal end of the catheter such that a distal end surface of the balloon is flush with a distal end surface of the catheter, the catheter comprising an inner surface defining a lumen, the distal end of the catheter comprising an opening that is in communication with the lumen, the catheter further comprising a port that is continuous with the lumen, wherein a proximal end of the catheter comprises a valve, the valve including a membrane; inserting a stylet through the membrane such that the stylet is removably disposed in the lumen to provide strength to the catheter, the stylet has a maximum diameter that is less than that of the lumen and the opening, the stylet having a length that prevents a distal tip of the stylet from being positioned distal to the distal end surface of the balloon; moving a material through the lumen and around the stylet such that the material exits the lumen through the opening and moves into the boney structure; and withdrawing the catheter from the patient. - View Dependent Claims (16, 17, 18, 19, 20)
