Benefits of technology

[0011] A device for accessing a biological lumen is disclosed. The biological lumen has a lumen wall having a longitudinal lumen wall axis. The device has an elongated member that has a longitudinal member ...

Problems solved by technology

This method is time-consuming, frequently requiring one-half hour or more of compression before hemostasis.
This procedure is uncomfortable for the patient and frequently requires administering analgesics.
Excessive pressure can also present the risk of total occlusion of the blood vessel, resulting in ischemia and/or thrombosis.
During this time bleeding from the vascular access wound can restart, potentially resulting in major complications.
This method generally presents d...

Embodiment Construction

[0068]FIGS. 1 through 3 illustrate a device for accessing a biological lumen, such as an arteriotomy device 2. The arteriotomy device 2 can have a delivery guide 4. The delivery guide 4 can be slidably attached to an anchor 6. The anchor 6 can be rigid, flexible or combinations thereof. The anchor 6 can be resilient, deformable or combinations thereof. The anchor 6 can be retractable and extendable from the delivery guide 4. The delivery guide 4 can have an introducer lumen 8. The introducer lumen 8 can have an introducer lumen exit port 10. The introducer lumen exit port 10 can be on the surface of the delivery guide 4.

[0069] The anchor 6 can have an anchor angle section 12. The anchor 6 can have an anchor extension section 14, for example a guide eye sheath or an attachable guidewire. The anchor extension section 14 can extend from the anchor angle section 12. The anchor extension section 14 can be separate from and attached to, or integral with, the anchor angle section 12.

Abstract

Devices and methods for accessing and closing vascular sites are disclosed. Self-sealing closure devices and methods are disclosed. A device that can make a steep and controlled access path into a vascular lumen is disclosed. Methods for using the device are also disclosed.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to the field of accessing a biological lumen and closing the access port thereby created. [0003] 2. Description of the Related Art [0004] A number of diagnostic and interventional vascular procedures are now performed translumenally, where a catheter is introduced to the vascular system at a convenient access location—such as the femoral, brachial, or subclavian arteries—and guided through the vascular system to a target location to perform therapy or diagnosis. When vascular access is no longer required, the catheter and other vascular access devices must be removed from the vascular entrance and bleeding at the puncture site must be stopped. [0005] One common approach for providing hemostasis is to apply external force near and upstream from the puncture site, typically by manual compression. This method is time-consuming, frequently requiring one-half hour or more of compression befo...
