US 12,702,397 B2 · Apparatus and method for sealing a vascular puncture

Abstract

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.

Claims26

Dependent claims

A sealant delivery system for closing a puncture in a vessel wall, the sealant delivery system comprising:

an inner catheter extending through an outer catheter and having an expandable structure at a distal end thereof;
and,
a handle portion at a proximal end of the inner catheter operatively connected to and movable with the outer catheter, the handle portion having a tension indicator configured to indicate information associated with an amount of tension being applied to the vessel wall by the expandable structure;
wherein the tension indicator comprises a sliding piece disposed entirely within the handle portion and operatively coupled to the inner catheter such that the sliding piece is movable relative to the handle portion based on the tension applied to the vessel wall by the expandable structure.

1 more element

A system for closing a puncture, the system comprising:

a housing;
a first rack member positioned within the housing and slidable within the housing;
a sealant sleeve coupled to the first rack member and movable with the first rack member;
a second rack member positioned within the housing and slidable within the housing;
a support member coupled to the second rack member and movable with the first rack member, and wherein at least a portion of the support member is positioned within a lumen of the sealant sleeve;
a sealant positioned in a distal end of the sealant sleeve, and wherein a distal end of the support member is positioned adjacent a proximal end of the sealant;
and
a deployment actuator configured to both:
engage the first rack member to actuate the first rack member in a first direction;
engage the second rack member to actuate the second rack member in a second direction opposite the first direction;
wherein the deployment actuator includes a first actuation feature configured to actuate the first rack member and wherein the deployment actuator includes a second actuation feature configured to actuate the second rack member, and wherein the second actuation feature of the deployment actuator is spaced from the first actuation feature of the deployment actuator such that the first actuation feature of the deployment actuator is configured to engage an actuation feature of the first rack member before the second actuation feature of the deployment actuator engages an actuation feature of the second rack member.
