Launched in 2006, this circumcision clamp is a single-use disposable device developed by Sunathrone BioMedical in Malaysia. The makers claim a number of significant advantages over previous designs of disposable clamps. The principal advantage appears to be the size of the device remaining on the penis for the duration of the healing period, which is considerably smaller than rival clamps. The Sunathrone Clamp comes in various sizes for use on males of all ages, from newborn to adults.

The next step involves detaching the tube section at the bayonet joint that is just visible (ringed) between the detached foreskin and the white clamping component. Once the tube has been detached, nothing protrudes beyond the tip of the exposed glans.

The prototype clamp we reviewed in January 2006 had one design flaw and one production method flaw. With some guidance from Circlist members, Sunathrone resolved these inadequacies and they should not be found in any device currently on sale. However, medical personnel should check all of the following:
- The detachable part of the tube should be joined using a bayonet joint, not a break-off line of weakness.
- The packaging should be marked Sterile-EO, not Sterile-R.
- The presence of a Batch Code plus an Expiry of Sterility date that remains valid.
Finally, it should be noted the clamp is designed to be used by a skilled physician or other trained healthcare provider. This is not a 'do it yourself' device.
