Guidewire Distal End

Guidewire distal end is the part of the guidewire that is away from the operator and usually the part in the artery. The guidewire distal ends are smooth and rounded. During the procedure, the surgeon uses the distal end of the guidewire to guide and properly position the catheter into the vessel. The smooth and rounded end of the guidewire facilitates the passage of the guidewire through the blood vessel, which reduces the risk of bleeding by minimizing damage to the vein wall.

How to make rounded and smooth distal end of guidewire?

Method for welding and forming guidewire tip

The common method used nowadays is the dispensing process. Firstly, the guidewire is fixed in the elastic clamping hole, and the head end of the guidewire is exposed, then the medical glue is applied to the head end of the guidewire, and finally the ultraviolet lamp is turned on to irradiate the head end of the guidewire, so that the medical glue at the head end of the guidewire is cured to shape and form a rounded smooth hemisphere that wraps around the head end of the guidewire.

However, the dispensing process is prone to dislodgement of the tip end of the guidewire, causing potential harm to both the physician and the patient. Dislodged dispensing material may become free within the blood vessel, leading to serious complications such as embolization and infarction.

Based on this, Cathetermelt has developed a new guidewire tip molding technology that can improve the debonding problem of dispensing technology, and its production efficiency is many times that of dispensing technology. It only needs around 15seconds for one guidewire tipping. Also CM110-3A guidewire tip forming machine is suitable for 0.014″ to 0.038″ coated guidewires. More details please contact us.
