Abstract
An introducer sheath is described. The introducer sheath may include a tubular body. The tubular body may extend from a distal end toward a proximal end. The tubular body may include a lumen. The lumen may at least partially be defined by a wall. A channel may be disposed within the wall. The channel may be configured to receive a guidewire. The tubular body may include an expandable portion expandable to increase a cross-sectional area of the lumen.
Claims20
An introducer sheath comprising:
- a tubular body extending from a distal end toward a proximal end, the tubular body comprising:
- a lumen defined at least partially by a wall;
- a secondary channel being disposed within the wall and configured to receive a guidewire.
An introducer sheath, comprising:
- a hub portion extending from a distal end toward a proximal end, the hub portion having a hub lumen formed therein;
- and
- a tubular body extending from a distal end toward a proximal end, the tubular body comprising:
- a lumen defined at least partially by a wall;
- a secondary channel being disposed within the wall and configured to receive a guidewire;
- and
- a portion of weakened structural integrity located between the lumen and the secondary channel, wherein the portion of weakened structural integrity splits when the body expands beyond a predetermined diameter and/or a predetermined expansion distance to increase a cross-sectional area of the tubular body.
A method for introducing a medical device into a body, the method comprising:
- positioning a sheath upon a guidewire disposed within a body lumen, the sheath comprising a tubular body extending from a distal end toward a proximal end, the tubular body comprising a lumen defined at least partially by a wall, a secondary channel being disposed within the wall and configured to receive the guidewire, and at least one deformable expandable portion configured to increase a cross-sectional area of the tubular body;
- introducing the sheath into the body lumen;
- and
- selectively inserting one or more medical devices into the body lumen through the sheath.
