Abstract
An introducer tool including a housing, a sheath detachably coupled to the housing, and a needle fixed to the housing. The housing can include a guidewire actuating mechanism configured to extend and retract a guidewire fixed to the guidewire actuating mechanism. The sheath can include a handle, and can be detachably coupled to the housing in a first configuration of the introducer tool designed for venous introduction of the sheath. An end portion of the needle can extend past an end portion of the sheath in the first configuration of the introducer tool. Methods for venous access including obtaining and using the introducer tool are also disclosed.
Claims17
An introducer tool, comprising:
- a housing including a guidewire actuating mechanism configured to extend and retract a guidewire fixed to the guidewire actuating mechanism;
- a sheath including a handle,
- wherein the sheath is detachably coupled to the housing in a first configuration of the introducer tool configured for venous introduction of the sheath;
- and
- a needle fixed to the housing,
- wherein an end portion of the needle extends past an end portion of the sheath in the first configuration of the introducer tool.
A method for venous access, comprising:
- obtaining a venous introducer tool including
- a housing including a guidewire actuating mechanism configured to extend and retract a guidewire fixed to the guidewire actuating mechanism;
- a sheath including a handle,
- wherein the sheath is detachably coupled to the housing in an initial configuration of the introducer tool;
- and
- a needle fixed to the housing,
- wherein an end portion of the needle extends past an end portion of the sheath in the initial configuration of the introducer tool;
- puncturing a vein of a patient with the needle of the introducer tool to gain venous access by way of a puncture;
- extending the guidewire into the vein past the end portion of the needle with the guidewire actuating mechanism;
- and
- introducing the sheath into the vein by sliding the sheath over the guidewire.
A method for venous access, comprising:
- obtaining an introducer tool including a housing including a guidewire actuating mechanism configured to extend and retract a guidewire fixed to the guidewire actuating mechanism;
- a peelable sheath including a handle, wherein the sheath is detachably coupled to the housing in an initial configuration of the introducer tool, and wherein the sheath is configured to peel apart from the handle to an end portion of the sheath;
- and
- a needle fixed to the housing, wherein an end portion of the needle includes a beveled section and a dilator section;
- puncturing a vein of a patient with the beveled section of the needle of the introducer tool to gain venous access by way of a puncture, wherein the end portion of the needle extends past the end portion of the sheath of the introducer tool for the puncturing of the vein;
- dilating the puncture with the dilator section of the needle;
- extending the guidewire into the vein past the end portion of the needle with the guidewire actuating mechanism;
- introducing the sheath into the vein by sliding the sheath over the guidewire. activating a needle-safety mechanism of the introducer tool;
- simultaneously withdrawing the needle from the puncture and enclosing at least the beveled section of the needle in a needle-safety housing of the needle-safety mechanism;
- withdrawing the guidewire while leaving the sheath in place;
- inserting a catheter into the vein through the sheath;
- and
- removing the sheath from the vein, wherein removing the sheath includes withdrawing the sheath from the vein while the catheter is disposed within the sheath and peeling the sheath apart from the handle to the end portion of the sheath.
