Abstract
A device for supporting surgical procedures and method of its manufacture include preparing a glass melt in a silica crucible, injecting a gas bubble into the glass melt, shaping the glass melt containing the gas bubble into a phosphate glass structure having a tubular shape, cooling the phosphate glass structure, wherein the phosphate glass structure includes a network-forming component and a modifier, and truncating the phosphate glass structure into a desired length to form the device, wherein the device has a dissolution rate of at least 50 mg cm−2 hr−1.
Claims31
A self-dissolving device for microvascular anastomosis, the device comprising:
- a phosphate glass matrix having a tubular shape, the phosphate glass matrix comprising:
- a network-forming component;
- and
- a modifier, wherein the modifier comprises at most 15 mol % of CaO and does not include MgO with respect to the phosphate glass matrix, wherein:
- the phosphate glass matrix has a glass melting temperature that is at least 1,000° C. and no greater than 1,200° C.;
- and
- the device has a dissolution time ranging from 2 minutes to 30 minutes.
A method of manufacturing a self-dissolving device for microvascular anastomosis, the method comprising:
- preparing a glass melt in a silica crucible;
- injecting a gas bubble into the glass melt;
- shaping the glass melt containing the gas bubble into a phosphate glass structure having a tubular shape;
- cooling the phosphate glass structure, wherein the phosphate glass structure comprises a network-forming component and a modifier;
- and
- truncating the phosphate glass structure into a desired length to form a phosphate glass matrix comprising:
- a network-forming component;
- and
- a modifier, wherein the modifier comprises at most 15 mol % of CaO and does not include MgO with respect to the phosphate glass matrix, wherein:
- the phosphate glass matrix has a glass melting temperature that is at least 1,000° C. and no greater than 1,200° C.;
- and
- the device has a dissolution time ranging from 2 minutes to 30 minutes.
A self-dissolving device for microvascular anastomosis, the device comprising:
- a phosphate glass matrix having a tubular shape, the phosphate glass matrix comprising:
- a network-forming component;
