Catheter with integrated cement delivery balloon

摘要

A bone filling device includes a catheter that defines a longitudinal axis and extends between a proximal end and a distal end. A first lumen extends along the longitudinal axis of the catheter and defines a first passageway. A second lumen extends along the longitudinal axis of the catheter and defines a second passageway. An inflatable body includes a wall that defines a fillable cavity. The fillable cavity is in fluid communication with the first passageway. A bone filler delivery port is continuous with the second passageway and is configured to dispense bone filling material.

主权项

1. A bone filling system comprising:
a cannula; a catheter inserted through the cannula and comprising an outer surface and an inner surface that define a wall thickness of the catheter, the catheter defining a longitudinal axis and extending between a proximal end and a distal end; a first lumen disposed within the wall thickness, the first lumen extending along the longitudinal axis and defining a first passageway; a second lumen disposed along the inner surface, the second lumen extending along the longitudinal axis and defining a second passageway; an inflatable body adhered to the catheter with an adhesive, the inflatable body having a wall defining a fillable cavity, the inflatable body being disposed along the outer surface and spaced from the cannula such that a distal tip of the catheter extends outwardly from a distal end surface of the inflatable body, wherein the fillable cavity is in fluid communication with the first passageway; and a bone filler delivery port continuous with the second passageway and configured to dispense bone filling material.
