Abstract
Some embodiments of the invention provide an apparatus for achieving hemostasis in a puncture tract that is created during a medical procedure. The puncture typically extends from the epidermis to the vasculature in a living organism. In some embodiments, the apparatus includes (1) a plug for subcutaneous placement within the puncture tract, and (2) a delivery mechanism for delivering and maintaining the plug within the puncture tract until hemostasis is achieved. The apparatus also includes in some embodiments a lubricious sheath that is placed around the plug to facilitate the insertion of the plug into the puncture tract.
Claims52
A method of achieving hemostasis in a puncture tract that is created during a medical procedure on a patient, the method comprising:
- inserting a guide wire into the puncture tract;
- sliding a bandage and a delivery mechanism coupled to the bandage over the guide wire in order to insert the bandage and at least a portion of the delivery mechanism into the puncture tract;
- after sliding the bandage and the delivery mechanism over the guide wire, removing the guide wire, wherein removing the guide wire causes a portion of the puncture tract to collapse;
- applying pressure to the delivery mechanism while maintaining the bandage in the puncture tract;
- and
- after removing the guide wire, pulling the delivery mechanism away from the puncture tract in order to remove the bandage from the puncture tract after a period of time, wherein said delivery mechanism is directly and fixedly coupled to the bandage while delivering and maintaining the bandage in the puncture tract and while removing the bandage from the puncture tract.
A method of operating a hemostatic device comprising a bandage and a delivery mechanism, said delivery mechanism comprising a pad having a surface and a stem coupled to the bandage, the method comprising:
- forming an opening and an access tract in skin of a patient;
- forming a vascular puncture at an end of the access tract, the vascular puncture extending through a wall of a vessel;
- directing the stem of the delivery mechanism toward a puncture tract to insert the bandage into the puncture tract but not through a vascular puncture, wherein a total length of the bandage and the stem of the delivery mechanism, when the bandage is fully deployed in the access tract to promote hemostasis, is less than the distance from the opening to the vascular puncture;
- maintaining the surface of the pad outside the puncture tract;
- applying pressure to the surface of the pad in order to apply pressure which maintains the bandage in the puncture tract;
- and
- after a period of time, pulling the delivery mechanism away from the puncture tract in order to remove the bandage from the puncture tract, said delivery mechanism being fixedly coupled to the bandage while maintaining the bandage in the puncture tract and while pulling the delivery mechanism away from the puncture tract.
A method of performing a medical operation, comprising:
- forming an access tract in skin of a patient through a percutaneous opening;
- forming a vascular puncture at an end of the access tract, the vascular puncture extending through a wall of a vessel;
- placing a guide wire through the access tract and the vascular puncture and into the vessel;
- threading an apparatus onto the guide wire, the apparatus including a bandage on a distal end of the apparatus, the apparatus further including a mechanism to deliver the bandage;
- advancing the apparatus into the access tract;
- stopping advancement of the apparatus prior to the apparatus reaching the wall of the vessel so that the bandage is positioned within the access tract proximal to the vascular puncture, at least a portion of the mechanism being positioned outside of the patient;
- while the apparatus is positioned in the access tract, removing the guide wire such that a portion of the access tract collapses;
- and
- without disconnecting the mechanism from the bandage, removing the bandage from the access tract through the percutaneous opening.
A method of performing a medical operation, comprising:
- creating an opening in an epidermis of a patient;
- forming an access tract in a subcutaneous tissue layer via the opening;
- forming a vascular puncture at an end of the access tract, the vascular puncture extending through a wall of a vessel;
- advancing a stem of an apparatus into the access tract, the apparatus including a bandage fixedly coupled on a distal end of the stem, wherein a total length of the bandage and the stem, when the bandage is fully deployed in the access tract to promote hemostasis, is less than the distance from the opening to the vascular puncture;
- and
- removing the stem and the bandage through the access tract with the stem fixedly coupled to the bandage.
A method of performing a medical operation, comprising:
- forming an access tract in a subcutaneous layer of skin via an opening in the skin;
- forming a vascular puncture through a wall of a vessel, the vascular puncture being located at a terminal end of the access tract;
- advancing an apparatus, the apparatus including a delivery mechanism and a bandage fixedly coupled to the delivery mechanism, into the access tract but not into contact with the wall of the vessel or into the vascular puncture, the apparatus promoting hemostasis without contacting the wall of the vessel;
- and
- after hemostasis occurs, removing the apparatus including the bandage back through the access tract.
A method of operating a hemostatic device comprising a bandage and a delivery mechanism coupled to the bandage, the method comprising:
- directing the delivery mechanism toward a puncture tract to insert the bandage into the puncture tract;
- maintaining a surface of the delivery mechanism outside the puncture tract;
- creating pressure between the bandage and the puncture tract to promote hemostasis when at least a portion of the puncture tract distal to the bandage is collapsed;
- and
- without disconnecting the delivery mechanism from the bandage, after a period of time, pulling the delivery mechanism away from the puncture tract in order to remove the bandage from the puncture tract.
