Medical balloon for a catheter

摘要

A medical balloon for deployment of stents is disclosed. The medical balloon includes a central section; a proximal and a distal cone section; a proximal and a distal shaft section; a proximal sleeve which is arranged coaxial to and radially inside the proximal shaft section. The proximal end of the proximal shaft section is permanently connected and/or unitarily formed with the proximal end of the proximal sleeve, and distal thereto, at least part of the proximal cone section is connected with the proximal sleeve by an adhesive bond, and a distal sleeve which is arranged coaxial to and radially inside the distal shaft section. Methods of manufacturing a medical balloon are disclosed.

1. A medical balloon for deployment of stents, comprising
a central section; a proximal and a distal cone section; a proximal and a distal shaft section; a proximal sleeve which is arranged coaxial to and radially inside the proximal shaft section, wherein a proximal end of the proximal shaft section is permanently connected and/or unitarily formed with a proximal end of the proximal sleeve, and distal thereto, at least part of the proximal cone section is connected with the proximal sleeve by an adhesive bond; and a distal sleeve which is arranged coaxial to and radially inside the distal shaft section, wherein a distal end of the distal shaft section is permanently connected and/or unitarily formed with a distal end of the distal sleeve, and proximal thereto, at least part of the distal cone section is connected with the distal sleeve by an adhesive bond, wherein, the adhesive bonds are adapted such that an inflation pressure for releasing the adhesively bonded parts of the proximal and distal cone sections from the respective proximal and distal sleeves is higher than an inflation pressure at which a center of the balloon starts expanding.
