Abstract
A radiation shield assembly (30) for a radioactive stent (11) mounted onto a deployment portion (20) of a delivery apparatus (12) including a relatively thin, elongated tube member (69) having a wall (70) defining a receiving passage (72) formed and dimensioned for axial receipt of the stent mounted onto the deployment portion therein to substantially prevent direct contact with the stent (11). A removal structure (71) cooperating with the wall (70) of the tube member (69) for longitudinal severing thereof to enable selective removal of the tube member from the delivery apparatus (12) for deployment use thereof.
Claims71
A radiation shield assembly for a deformable stent mounted onto a deployment portion of a delivery apparatus comprising:
- an elongated tube member defining a receiving passage formed and dimensioned for axial receipt of the stent mounted onto the deployment portion of the delivery apparatus therein to substantially prevent exposure to radiation of the stent, said tube member having a relatively thin wall portion, relative the length thereof, extending longitudinally from substantially one end of the tube member to an opposite end thereof;
- and
- removal structure cooperating with the thin wall portion of the tube member for longitudinal severing of the thin wall portion substantially from the one end of the tube member to the opposite end thereof to enable selective removal of the tube member from the delivery apparatus for deployment use thereof.
A radiation shield assembly for a deformable radioactive stent mounted onto a deployment portion of a delivery apparatus comprising:
- an elongated tube member having a wall defining a receiving passage formed and dimensioned for axial receipt of the stent mounted onto the deployment portion of the delivery apparatus therein;
- and
- radiation shield device removably disposed peripherally about at least a portion of said elongated tube member such that said stent and said deployment portion are substantially contained within said shield device to substantially prevent the passage of radioisotopes emitted from the stent radially out of said shield device.
A method of storing a deformable stent mounted onto a deployment portion of a delivery apparatus for transport and delivery comprising:
- containing the stent and the deployment device into an axially extending receiving passage of a relatively thin, elongated tube member to substantially prevent direct contact with the stent;
- and
- providing removal structure cooperating with a wall of the tube member for longitudinal severing thereof to enable selective removal of the delivery apparatus from the tube member for deployment use thereof.
A method of delivering a deformable radioactive stent mounted onto a deployment portion of a delivery apparatus into a vessel comprising:
- containing the stent and the deployment device in a passage of an elongated tube member to substantially prevent direct contact with the stent;
- placing a proboscis portion of the tube member in communication with a fitting for receipt into the vessel;
- axially advancing the mounted stent and the deployment device, relative the tube member, into the fitting;
- and
- removing the tube member from impeding contact with the delivery apparatus.
A shield assembly for a deformable stent mounted onto a deployment portion of a delivery apparatus comprising:
- a relatively thin, elongated tube member having a wall defining a receiving passage formed and dimensioned for axial receipt of the stent mounted onto the deployment portion of the delivery apparatus therein to substantially prevent direct contact with the stent;
- removal structure cooperating with the wall of the tube member for longitudinal severing thereof to enable selective removal of the tube member from the delivery apparatus for deployment use thereof;
- and
- a retaining mechanism having a pair of opposed engaging fingers movable between an engaged condition, adapted to contact the delivery apparatus for frictional engagement therewith to prevent axial displacement of the stent and delivery apparatus relative the tube member, and a disengaged condition, permitting axial displacement therebetween.
A shield assembly for a deformable stent mounted onto a deployment portion of a delivery apparatus comprising:
- a relatively thin, elongated tube member having a wall defining a receiving passage formed and dimensioned for axial receipt of the stent mounted onto the deployment portion of the delivery apparatus therein to substantially prevent direct contact with the stent;
- removal structure cooperating with the wall of the tube member for longitudinal severing thereof to enable selective removal of the tube member from the delivery apparatus for deployment use thereof;
- a retaining mechanism positioned proximate a proximal section of said tube member and coupled thereto to selectively prevent axial displacement between the deployment device and the tube member, said retaining device further including a seal device adapted to form a hemostatic seal with said delivery apparatus when in the engaged therewith to seal the proximal end of said passage.
