Problems solved by technology

This procedure, however, may be time consuming and expensive, requiring as much as an hour of a physician's or nurse's time.
It is also uncomfortable for the patient and requires that the patient remain immobilized in the operating room, catheter lab, or holding area.
In addition, a risk of hematoma exists from bleeding before hemostasis occurs.
This device, however, requires that an anchor of the plug be positioned within the vessel, and therefore, may increase the risk of over-advancement of the plug itself into the vessel.

Embodiment Construction

[0022]Embodiments described herein extend to methods, systems, and apparatus for closing and / or sealing openings in a blood vessel or other body lumen formed during a diagnostic, therapeutic, and / or other procedure. The closure elements of the present invention may be configured to be delivered through tissue and into an opening formed in and / or adjacent to a wall of a blood vessel or other body lumen. The closure elements provided herein may reliably engage.

[0023]FIGS. 1A-1D illustrate an embodiment of a closure element 10. The closure element (also referred to herein as a “clip”) 10 can have a generally annular-shaped body 12 defining a channel 14. The channel 14 may include an axis 30. In the present embodiment, the axis 30 may be a central axis. In other embodiments, the axis 30 may be a non-central axis. The closure element 10 may include one or more barbs and / or tines 16 for receiving and engaging tissue (a blood vessel wall for example). The tines 16 in the present embodiment...

Abstract

A closure element includes a coiled body and a plurality of tissue engaging portions. The tissue engaging portions disposed about at least a portion of the coiled body. The coiled body is formed of a resilient material according to one example. According to another example, a closure element includes a spiral body and a plurality of tissue engaging portions disposed about the spiral body. The spiral body is formed from a resilient material.
