Vascular remodeling devices can include a proximal section, an intermediate section, and a distal section. During deployment, the proximal section can expand from a compressed delivery state to an expanded state and anchor the device in an afferent vessel of a bifurcation. The distal section expands from the compressed delivery state to an expanded state that may be substantially planar, approximately semi-spherical, umbrella shaped, or reverse umbrella shaped. The distal section is positioned in a bifurcation junction across the neck of an aneurysm or within an aneurysm. The intermediate section allows perfusion to efferent vessels. Before or after the device is in position, embolic material may be used to treat the aneurysm. The distal section can act as a scaffolding to prevent herniation of the embolic material. The device can be used for clot retrieval with integral distal embolic protection.

Vascular remodeling device

Described herein are vascular remodeling devices that include a proximal section, an intermediate section, and a distal section. During deployment, the proximal section can expand from a compressed delivery state to an expanded state and anchors the device in an afferent vessel of a bifurcation. The distal section expands from the compressed delivery state to an expanded state that may be substantially planar, approximately semi-spherical, umbrella shaped, or reverse umbrella shaped. The distal section is positioned in a bifurcation junction across the neck of an aneurysm or within an aneurysm. The intermediate section allows perfusion to efferent vessels. Before or after the device is in position, embolic material may be used to treat the aneurysm. The distal section can act as a scaffolding to prevent herniation of the embolic material. The device can be used for clot retrieval with integral distal embolic protection.

A surgical clip applier includes a handle assembly, a first clip assembly, and a second clip assembly. The first clip assembly is adapted to receive only a single clip while the second clip assembly is adapted to receive multiple clips. The handle assembly is sized and configured to receive the first clip assembly or the second clip assembly. A jaw assembly includes a pair of jaws each with an elongate support arm, and a bridge holding the jaws in an aligned relationship. A housing has a fixed relationship with the bridge while permitting movement of the jaws between an open and a closed state. A coupling attaches the housing to the handle assembly. An associated method of operation includes the step of removing one of the single clip jaw assembly and the multiple clip-jaw assembly, disposing of the one jaw assembly while mounting the other jaw assembly on the handle.
