Systems and methods for reducing fractured bone using a fracture reduction cannula

Systems and methods provide for the fixation of osteoporotic and non-osteoporotic long bones, especially Colles' fractures. A cannula having a circumferential opening is inserted into cancellous bone and directed such that the circumferential opening faces the fracture. The cannula is further adapted to receive an expandable structure, the expandable structure being inserted through the cannula until it is in registration with the circumferential opening. The expandable structure is expanded through the circumferential opening into cancellous bone and toward the fracture.

A bushing extends from the coupling and is configured to be inserted within an opening in the port of the insertion device. The elongated instrument is movably extendable through the bushing. A first sealing member is disposed on an outer surface of the bushing to seal the outer surface of the bushing against an inner surface of the opening in the port. A second sealing member is disposed on an outer surface of the elongated instrument to movably seal an outer surface of the elongated instrument.

Real Time Sampling Device

Needle device with activation force limiter

A medical instrument having an aspiration needle, handle device and an actuation force limiter. The actuation force limiter provides an active or passive force release mechanism that keeps the force from overpowering operation of the needle.

Sheath location indicator and overextension preventer

An apparatus for controlling advancement of a sheath or a catheter at a distal end of an endoscope. An exemplary apparatus includes a flexible sheath that receives a medical device within an internal lumen and is received within a working channel of an endoscope. The apparatus also includes a component that is at least one of external or internal to the sheath. The component causes a change in longitudinal motion friction of the sheath above a predefined threshold amount as the sheath moves relative to an exit ramp of the endoscope.
