Device for performing a surgical procedure and method
A medical balloon device includes an outer member extending along an axis. An inflatable member has a proximal end extending from a first end of the outer member and a distal end. An inner member is positioned within the outer member and the inflatable member such that a first end of the inner member is coupled to the distal end of the inflatable member. A support member is movably disposed within the inner member and includes a first end configured to removably engage the first end of the inner member. Translation of the support member along the axis causes the inflatable member to move between a first position in which the inflatable member has a first length and a first profile and a second position in which the inflatable member has a second reduced length and a second reduced profile. Methods of use are disclosed.
1. A surgical device comprising:
a sleeve;
a shaft disposed in the sleeve, the shaft defining a passageway;
a stopper disposed in the passageway;
a balloon having a first end coupled to the sleeve and a second end coupled to the shaft, the balloon defining a chamber; and
a support member disposed within the passageway and moveable relative to the shaft between a first position in which an end of the support member is spaced apart from the stopper and a second position in which the end of the support member is positioned within the stopper.
2. The surgical device recited in claim 1 , wherein the support member is prevented from rotating relative to the shaft when the support member is in the second position.
3. The surgical device recited in claim 1 , wherein the end of the support member engages a surface of the stopper when the support member is in the second position to prevent the support member from rotating relative to the shaft.
4. The surgical device recited in claim 1 , wherein the support member is configured to translate relative to the sleeve when the support member is in the second position to increase a length of the balloon.
5. The surgical device recited in claim 1 , wherein rotation of the shaft relative to the sleeve when the support member is in the second position causes the balloon to twist about the shaft.
6. The surgical device recited in claim 1 , wherein the stopper has an opening, the end of the support member including a stepped portion configured for disposal in the opening of the stopper when the support member is in the second position.
7. The surgical device recited in claim 6 , wherein the opening and the stepped portion each have a configuration configured to engage one another to prevent rotation of the support member within the stopper when the support member is in the second position.
8. The surgical device recited in claim 6 , wherein the opening and the stepped portion each have a polygonal configuration configured to engage one another to prevent rotation of the support member within the stopper when the support member is in the second position.
9. The surgical device recited in claim 6 , wherein the opening and the stepped portion each have a configuration configured to engage one another to prevent rotation of the support member within the stopper when the support member is in the second position such that rotation of the shaft relative to the sleeve when the support member is in the second position causes the balloon to twist about the shaft.
10. The surgical device recited in claim 1 , further comprising a marker band coupled to an outer surface of the shaft such that the marker band is spaced apart from the sleeve.
11. The surgical device recited in claim 1 , wherein the sleeve is made from a material having a lower modulus of elasticity than a material from which the support member is made.
12. The surgical device recited in claim 1 , wherein the shaft is made from a material having a lower modulus of elasticity than a material from which the support member is made.
13. The surgical device recited in claim 1 , wherein the balloon is made from a material having a lower modulus of elasticity than a material from which the support member is made.
14. The surgical device recited in claim 1 , wherein the passageway is coaxial with the channel.
15. The surgical device recited in claim 1 , wherein the shaft comprises an inner surface defining the passageway, the stopper having an outer surface that directly engages the inner surface.
16. The surgical device recited in claim 1 , wherein the stopper forms a plug that completely fills a portion of the passageway.
17. A surgical device comprising:
a sleeve;
a shaft disposed in the sleeve, the shaft defining a passageway;
a stopper disposed in the passageway;
a balloon having a first end coupled to the sleeve and a second end coupled to the shaft, the balloon defining a chamber; and
a support member disposed within the passageway and moveable relative to the shaft between a first position in which an end of the support member is spaced apart from the stopper and a second position in which the end of the support member is positioned within the stopper,
wherein the support member is prevented from rotating relative to the shaft when the support member is in the second position, and
wherein the end of the support member engages a surface of the stopper when the support member is in the second position to prevent the support member from rotating relative to the shaft.
18. The surgical device recited in claim 16 , wherein the support member is configured to translate relative to the sleeve when the support member is in the second position to increase a length of the balloon.
19. The surgical device recited in claim 16 , wherein rotation of the shaft relative to the sleeve when the support member is in the second position causes the balloon to twist about the shaft.
20. A surgical device comprising:
a sleeve;
a shaft disposed in the sleeve, the shaft defining a passageway;
a stopper disposed in the passageway;
a balloon having a first end coupled to the sleeve and a second end coupled to the shaft, the balloon defining a chamber; and
a support member disposed within the passageway and moveable relative to the shaft between a first position in which an end of the support member is spaced apart from the stopper and a second position in which the end of the support member is positioned within the stopper,
wherein the shaft comprises an inner surface defining the passageway, the stopper having an outer surface that directly engages the inner surface, and
wherein the stopper forms a plug that completely fills a portion of the passageway.
21. The surgical device recited in claim 19 , wherein the support member is prevented from rotating relative to the shaft when the support member is in the second position.
