Abstract
A surgical kit includes a cannula assembly and a sheath. The cannula assembly includes a housing, an elongate shaft defining a lumen and extending from the housing, a fluid port adapted to be coupled to a fluid source, and an expandable body in fluid communication with the fluid port. The sheath is configured to be disposed over the expandable body of the cannula assembly to apply a compressive force to the expandable body. The sheath is transitionable between a contracted configuration and an expanded configuration.
Claims19
A surgical kit comprising:
- a cannula assembly including a housing, an elongate shaft defining a lumen and extending from the housing, a fluid port adapted to be coupled to a fluid source, and an expandable body in fluid communication with the fluid port;
- and
- a sheath disposed over the expandable body of the cannula assembly to apply a compressive force to the expandable body during radial expansion of the expandable body of the cannula assembly, wherein the sheath is transitionable between a contracted configuration and an expanded configuration, the sheath formed of a gas permeable and compliant material such that the sheath disposed over the expandable body of the cannula assembly is expandable to enable a predetermined amount of radial expansion of the expandable body of the cannula assembly.
A surgical kit comprising:
- a surgical instrument including an expandable body adapted to be coupled to a fluid source;
- and
- a sheath removably disposed over the expandable body of the surgical instrument to apply a compressive force to the expandable body of the surgical instrument during transition of the expandable body of the surgical instrument to an expanded configuration from a contracted configuration, wherein the sheath is formed of a gas permeable and compliant material to enable a predetermined amount of radial expansion of the expandable body of the surgical instrument.
