Device for performing a surgical procedure and method
A medical balloon device includes an outer member extending along an axis. An inflatable member has a proximal end extending from a first end of the outer member and a distal end. An inner member is positioned within the outer member and the inflatable member such that a first end of the inner member is coupled to the distal end of the inflatable member. A support member is movably disposed within the inner member and includes a first end configured to removably engage the first end of the inner member. Translation of the support member along the axis causes the inflatable member to move between a first position in which the inflatable member has a first length and a first profile and a second position in which the inflatable member has a second reduced length and a second reduced profile. Methods of use are disclosed.

A manual mixer serves to facilitate mixing and agitating materials for use during surgery. For example, the manual mixer includes a body portion defining an interior area, a mixing assembly provided in the interior area of the body portion, a crank assembly for actuating the mixing assembly, and a valve assembly. The mixing assembly serves to mix and agitate the materials provided in the interior through rotation of a plunger portion and a spring attached thereto, and through upwards and downwards movement of the plunger portion in the interior area. Rotation of the crank assembly serves to rotate the plunger portion and the spring attached thereto, and effectuate upwards and downwards movement of the plunger portion. The valve assembly can be opened to facilitate dispensing of the materials from the interior area.
