Abstract
Percutaneous access sheaths used to provide access to the vasculature and heart for the introduction of percutaneous ventricular assist devices (pVADs), and to remain in place for the duration of pVAD use. The sheaths include actively closeable seals engageable to seal against the drive lines of the pVADs to minimize blood loss during pVAD use.
Claims7
A percutaneous access sheath comprising:
- an elongate tubular sheath having a sheath lumen and proximal and distal openings fluidly coupled to the sheath lumen;
- a seal having a seal lumen;
- and
- at least one compression member advanceable against a wall of the seal to push a portion of the wall into the lumen to move the seal lumen to a sealing position, wherein the at least one compression member includes a plurality of fingers pivotable to push at least partially opposed portions of the wall into the seal lumen;
- and an actuator moveable to simultaneously pivot the plurality of fingers to move the seal lumen to the sealing position.
2 more elements
A method of using a percutaneous sheath, comprising:
- providing a percutaneous sheath having a sheath lumen and proximal and distal openings fluidly coupled to the sheath lumen, and a seal having a seal lumen;
- and
- advancing at least one compression member against a wall of the seal to push a portion of the wall into the lumen to move the seal lumen to a sealing position, wherein advancing the at least one compression member includes moving an actuator to simultaneously pivot a plurality of fingers to push at least partially opposed portions of the wall into the seal lumen.
