Abstract
An apparatus for deploying and retrieving a self-expanding intravascular stent includes an intravascular delivery wire and floating marker band movably retained over the intravascular stent delivery wire and releasably mounting the self-expanding intravascular stent. The floating marker band is movably retained to a fixed marker band, and a distance between the fixed marker band and the floating marker band is variable and self-adjusting. One or more struts of the self-expanding intravascular stent are releasably constrained between a catheter wall and one or more sides of the floating marker band.
Claims16
An apparatus for deploying and retrieving a self-expanding intravascular medical device, comprising:
- an intravascular pusher wire having a distal portion and a proximal portion;
- at least one floating marker band movably constrained over the intravascular pusher wire, said at least one floating marker band being configured to releasably mount a self-expanding intravascular medical device thereon;
- and
- at least one fixed marker band fixedly attached to the intravascular pusher wire, wherein said at least one floating marker band is movably retained to said at least one fixed marker band by at least one constraining member configured to allow limited axial movement of said at least one floating marker band an axial distance between said at least one fixed marker band and said at least one floating marker band, wherein said at least one constraining member comprises a retainer wire, and wherein said retainer wire connected to said at least one fixed marker band.
