Abstract
Apparatus for sequentially forming, wrapping and compressing a catheter balloon either during the initial manufacturing process or after a medical procedure. The balloon may be formed, wrapped and compressed by simply advancing the balloon through a balloon wrapping tool and selectively inflating and deflating the balloon therein. The balloon wrapping tool preferably includes a flap forming bore, a flap wrapping bore and a flap compression bore which form, wrap and compress the balloon, respectively, when the balloon is advanced therethrough.
Claims16
Apparatus for wrapping a balloon of a balloon catheter, comprising:
- a tubular member having a flap forming section and a flap wrapping section;
- the flap forming section having a flap forming bore extending therethrough, the flap forming bore having a shape that produces at least three flaps in the balloon when the balloon is inflated and subsequently deflated therein;
- and
- the flap wrapping section having a flap wrapping bore extending therethrough, wherein the flap wrapping bore is axially aligned with the flap forming bore, and has a shape that wraps the at least three flaps of the balloon onto the catheter as the deflated balloon is advanced therethrough.
Apparatus for wrapping a balloon of a balloon catheter, comprising:
- a tubular member having a flap forming section, a flap wrapping section and a flap compression section;
- the flap forming section having a flap forming bore extending therethrough, the flap forming bore having a shape that produces at least three flaps in the balloon when the balloon is inflated and subsequently deflated therein;
- the flap wrapping section having a flap wrapping bore extending therethrough, wherein the flap wrapping bore is axially aligned with the flap forming bore, and has a shape that wraps the at least three flaps of the balloon onto the catheter as the deflated balloon is advanced therethrough;
- the flap compression section having a compression bore extending therethrough, wherein the compression bore is axially aligned with the flap wrapping bore.
Apparatus for wrapping a balloon of a balloon catheter, comprising:
- a first tubular section having a proximal end and a distal end and a flap forming bore extending therethrough;
- a second tubular section having a proximal end and a distal end, wherein the proximal end of the second tubular section is adjacent the distal end of the first tubular section, and said second tubular section having a flap wrapping bore extending from the proximal end to the distal end of the second tubular section, wherein the flap wrapping bore is in fluid communication with the flap forming bore of the first tubular section;
- a third tubular section having a proximal end and a distal end wherein the proximal end of the third tubular section is adjacent the distal end of the second tubular section, said third tubular section having a flap compression bore that is in fluid communication with the flap wrapping bore of the second tubular member;
- said flap forming bore having a shape that produces at least three flaps when the balloon is inflated and subsequently deflated therein;
- said flap compression bore having a different size and shape from the flap forming bore;
- and
- said flap wrapping bore providing a transition form the flap forming bore to the flap compression bore, and having a shape that causes the at least three flaps of the balloon to become wrapped around the catheter when the balloon is advanced from the flap forming bore to the flap compression bore.
