Abstract
A procedural sheath and methods of use that assists in maintaining a fluid path while the procedural sheath is positioned within a vascular conduit of a patient. The procedural sheath includes one or more channels extending longitudinally along a working length of the body of the sheath. Each channel includes one or more fluid paths configured to allow blood to flow from the vascular conduit into a device receiving lumen of the sheath. One or more elongate members selectively coupled to the body operatively cooperate with the channels to fluidly control fluid access into the device receiving lumen through the fluid paths.
Claims30
A procedural sheath comprising:
- an elongate body having a proximal end, a distal end, a device receiving lumen extending from the proximal end to the distal end, and a channel extending along a working length of the body, the device receiving lumen being generally uniform in diameter along the working length of the body;
- an elongate member selectively coupled to the body;
- and
- a plurality of fluid paths formed in a base of the channel, each of the plurality of fluid paths includes an inlet in the base of the channel and an outlet at the device receiving lumen,
- wherein the elongate member operatively cooperates with the channel and fluidly controls fluid access into the device receiving lumen of the body through the plurality of fluid paths by selectively opening and closing the inlets.
A large-bore procedural sheath comprising:
- a body comprising a proximal end, a distal end, and a length extending therebetween;
- a plurality of channels on an exterior surface of the body extending longitudinally along at least about 70% of the length of the body;
- a device receiving lumen having a substantially uniform diameter along a length of the device receiving lumen from the proximal end to the distal end of the body, the lumen configured to receive a procedural device therein;
- and
- a plurality of fluid paths formed in each channel of the plurality of channels, each of the plurality of fluid paths comprising an inlet formed at one of the plurality of channels and an outlet formed at the device receiving lumen, wherein the device receiving lumen fluidly communicates with the plurality of channels through the plurality of fluid paths.
A procedural sheath comprising:
- a body having a length extending between a proximal end and a distal end thereof;
- a device receiving lumen extending longitudinally inside the body, the device receiving lumen having a substantially uniform diameter along a length of the lumen from the proximal end to the distal end of the body;
- a channel extending on the surface of the body longitudinally along at least about 70% of the length of the body;
- a plurality of support regions disposed along a length of the channel;
- a plurality of fluid paths formed between the channel and the device receiving lumen;
- an elongate member;
- and
- a hub coupled to the proximal end of the body, the hub configured to selectively move the elongate member between a first configuration and a second configuration,
- wherein, in the first configuration, the elongate member is received within the channel and the elongate member covers the plurality of fluid paths in the channel so that the device receiving lumen does not fluidly communicate with the channel through the plurality of fluid paths, and
- wherein, in the second configuration, portions of the elongate member that are disposed between support regions along the length of the channel extend radially outward from the channel, the elongate member in the second configuration uncovering the plurality of fluid paths in the channel so that the device receiving lumen fluidly communicates with the channel through the plurality of fluid paths and the elongate member exerts a force against an interior surface of a vascular wall.
A method for performing an intravascular procedure while maintaining a fluid path through a vascular conduit, comprising:
- providing a procedural sheath, the procedural sheath comprising:
- a body comprising a channel with a plurality of fluid paths formed in a base of the channel, each of the plurality of fluid paths includes an inlet in the base of the channel and an outlet at a device receiving lumen of the body, the device receiving lumen being generally uniform in diameter along the length of the body;
- an elongate member selectively coupled to the body, the elongate member operatively cooperating with the channel and fluidly controlling fluid access into the device receiving lumen of the body through the plurality of fluid paths by selectively closing the inlets;
- advancing the procedural sheath into the vascular conduit;
- moving the elongate member radially outwardly from the body to push radially outwardly on an inside surface of the conduit and allow fluid access into the device receiving lumen of the body;
- and
- advancing a procedural device into the device receiving lumen of the body.
