APPARATUS AND METHOD FOR SEALING A VASCULAR PUNCTURE

摘要

A closure system for delivering a sealant to an arteriotomy. A distal section of the closure system can include overlapping inner and outer sleeves that can expand with expansion of the sealant. A proximal section of the closure system can include a handle portion and a sheath adapter extending from the handle portion. The handle portion can comprise one or more actuators that when depressed or engaged can assist in deployment of the sealant in the arteriotomy and can further include tamping of the sealant and/or retraction of an expandable member. The sheath adapter can removably engage a side port or an irrigation line of a standard procedural sheath. When the sheath adapter is secured to the procedural sheath, movement of the closure system can also move the procedural sheath.

1. A method for sealing an arteriotomy comprising:
advancing a closure system through a procedural sheath extending through the arteriotomy, the closure system comprising:
a handle portion;a sheath adapter extending from the handle portion, the sheath adapter comprising an attachment structure;an outer catheter extending from the handle portion;an inner catheter extending through the outer catheter, the outer catheter removably secured to the inner catheter;a support tube radially between the outer catheter and the inner catheter; anda sealant positioned in a distal section of the outer catheter; securing the sheath adapter of the closure system to the procedural sheath by releasably attaching the attachment structure of the sheath adapter to a side port or an irrigation line of the procedural sheath; and retracting the handle portion to retract the procedural sheath and the outer catheter relative to the inner catheter to expose the sealant.
