Description

technical field [0001] The invention relates to the field of medical technology, in particular to a medical neurosurgical balloon injection molding device. Background technique [0002] Medical balloons are used to administer a variety of treatments. For example, during angioplasty procedures, balloons may be used to widen constricted body blood vessels, such as coronary arteries. Balloons can also be used to deliver tubular members such as stents that are placed in the body to strengthen or reopen blocked blood vessels. In angioplasty, balloons can be used to treat stenosis, or narrowing, of blood vessels in the body by collapsing the balloon and delivering it to regions of the vessel that have been narrowed to the extent that blood flow is restricted. The balloon can be delivered to the target site by threading the catheter over a placed guide wire and advancing the catheter to the site. In some cases, the path to this site can be quite tortuous and / or narrow. After re...
