Intra cardiac foreign bodies are frequent occurrences in clinical cardiology practice. The common ones are intra chamber clots , vegetations and rarely tumors. Some of these masses are very mobile are precariously attached to the cardiac strutures . It becomes a cardiac emergency as a major embolic event is imminent .
While surgery remains the mainstay approach in such situations , now it seems possible to trap these mobile masses with help of catheter and retrieval devices safely.
The only issue is , while retrieving these masses it should not be let into the circulation and result in embolisation . For this we can develop a porous net (Fishing net like ) that can be blown in the distal chamber or Aorta .
Devices can be structured in way that a single catheter can be used with different ports to capture and filter and retrieve the mass . ( vacuum enabled suction catheters can be additional option ) .The whole procedure can be accomplished with fluroscoy and fluroscopic guidance . Intra cardiac echocardiography might also contribute .
This innovation will be a great value addition to the interventional cardiology armamentarium ,would be be appreciated by clinical cardiologists . We in our tertiary teaching hospital have felt the need for a such a device quiet often .Currently many patients land up in surgical tables for the sole purpose of removing these clots and vegetations .Similarly left atrial clots becomes a contraindication for percutaneous mitral commissurotomy(PTMC) . Such capture devices can be very useful.

Pigtail Catheter is exclusively used for abscess drainage such as bile, urine or pancreatic fluids. Only trained man power only should install and use Pigtail Catheter in order to avoid injuries in the track. A range of Polymers are used for the construction of Pigtail Catheters including silicone rubber, latex, and thermoplastic elastomers. The most common material for manufacturing Pigtail Catheter is silicone because it is inert and un reactive to body fluids and a range of medical fluids with which it might come into contact.
