This last part of surgery, namely, operations, is a reflection on the healing art; it is a tacit acknowledgement of the insufficiency of surgery. It is like an armed savage who attempts to get that by force which a civilised man would get by stratagem. 

In search of the missing hand of ‘collaborative action’: evidence from the Indian medical device industry

It is revealed that existence of a weak collaborative linkage between medical device manufacturers and the Indian health system, which largely lacks a systemic and cross-sectoral linkages, and weak communication between industry and government policy-makers have become a huge barrier to the development of the Indian MDI in the contemporary neo-liberal environment.

Chitra heart valve: results of a multicenter clinical study.

The Chitra valve appears to be safe and to have performance comparable with that of other currently used tilting disc valves, and is therefore within reach of a larger subset of Indian patients.

Synthetic Sapphire as an Artificial Heart Valve Occluder—Promise and Problems

A tilting disc artificial heart valve using a synthetic sapphire disc and a titanium nitride coated Haynes alloy cage was developed and successfully completed the accelerated durability test as per international protocol.

A tilting disc valve — component materials and hydraulic function

The results indicate that the performance of the indigeneous valve is comparable, if not marginally better, to that of the well-established Bjork-Shiley valve.

Heparin Bonding on Colloidal Graphite Surfaces

Experiments on clotting, both in vitro and in vivo, showed that a colloidal graphite surface, when rinsed with a cationic, surface-active agent, was capable of bonding heparin. The resistance of this

Electrical activity of the canine liver.

Evaluation of materials for artificial heart valves

The physical and mechanical requirements of the materials used in the Chitra heart valve have been evaluated by studying their water absorption, adhesive wear and abrasive properties and results show UHMW-PE to be a highly wear-resistant material suitable for the occluder.


Outflow obstruction of the hepatic veins, hypoproteinemia, 1 and hyperaldosteronism 2 have been implicated in its etiology and additional factors have been suggested to play a role in the formation of ascites.

A geochemical basis for endomyocardial fibrosis.

Endomyocardial tissue samples obtained from patients at necropsy or operation were analysed for major elements present in laterite and monazite, which are important soil constituents of Kerala State of India, and data show that thorium can become concentrated in cardiac tissues.
