IUB Review – The IUD Has Some Serious Competition!

The field of LARC in general and IUDs in particular has seen few innovations in the last few decades. Most IUDs manufactured to date are T shaped or a version of T shape and only a few are different (thread, rings, and others), however when deployed in the uterus they all take a 2 dimensional shape. We report here on a new IUD, the IUB (Intrauterine Ball).

 

The IUB is a copper intrauterine device which upon insertion in the uterus takes a three dimensional spherical form. The IUB™ is deployed and removed in the same manner as standard IUDs and is expected to have the same efficacy. Due to its form and deployment process the IUB™ is expected to reduce perforation, malposition and expulsion rates and may also reduce dysmenorrhea and menorrhagia.

 

The IUB™ is a single use IUD and is supplied sterile, pre-loaded into a simple tube (outer diameter = 3.2mm) and rod insertion kit. The IUB™ is made of a shape memory alloy wire, a material with superior elastic characteristics which tolerates flexion well while always returning to its preset shape. The wire is covered with a thin white polymer coating, applied mostly to improve visibility. 17 pure copper spheres are threaded over the wire (see Figures 1 and and22 below). The distal sphere is attached at one end to reduce sharpness and the proximal sphere is attached together with the thread. The total copper surface area is 300mm2 (a version of 380 also exists). A 20cm long double-tailed uncolored nylon monofilament thread is attached for removal. Once deployed, the IUB™ is approximately 12mm in diameter; however, it is likely to accommodate its shape to the uterine cavity. The IUB™ is intended to have a lifetime of five years.

 

Fifteen women were followed for one year, with follow-up visits at 1, 3, 6, 9, and 12 months when testing the IUB.

 

Results included a physician’s report that all devices were very easy to insert. There were no perforations, expulsions, mal-positions or complications, or pregnancies.

No safety or efficacy concerns were raised.

 

Due to its form and deployment process the IUB™ is expected to ease insertion and reduce perforation, malposition and expulsion rates and may also reduce dysmenorrhea and menorrhagia.
