Abstract
Devices and methods for providing an internal balloon sheath. One device includes a sheath for insertion through an arteriotomy of a patient. The sheath comprises a tubular sheath body having a longitudinal axis, an open proximal end, an open distal end, an outer surface and an inner surface, the inner surface defining a lumen between the proximal and distal ends for passage of a catheter device. The sheath also comprises an inflatable balloon disposed within the lumen. The inflatable balloon is configured to occupy a longitudinal space in the lumen between the inner surface of the sheath body and the catheter device when the catheter device is disposed within the sheath and the balloon is inflated, and fluidically seal the lumen.
Claims17
An introducer sheath assembly comprising:
- a tubular sheath body having a proximal end, a distal end, and a lumen extending between the proximal and distal ends for passage of a catheter device;
- and
- a balloon sleeve having an inflatable balloon, the balloon sleeve being axially aligned and in-line with the catheter device, the balloon sleeve being co-axially arranged around the catheter device, and the balloon sleeve being configured to traverse the lumen of the tubular sheath body such that the inflatable balloon forms a fluidic seal between the tubular sheath body and the catheter device when the inflatable balloon is inflated,
- wherein the inflatable balloon is disposed on a length of an external surface of the balloon sleeve.
