Improvised device for negative-pressure leak test

Improvised Nuclear Device Case Study

A new device for paravalvular leak closure

Percutaneous closure of a prosthetic paravalvular leak (PVL) is a challenging procedure. Operators must use devices constructed for other applications. We present the use of a device which is specifically designed for PVL closure. To the best of our knowledge, there is no publication in MEDLINE reporting the use of the device.

Improvised Comedy as a Turing Test

The best improvisational theatre actors can make any scene partner, of any skill level or ability, appear talented and proficient in the art form, and thus "make them shine". To challenge this improvisational paradigm, we built an artificial intelligence (AI) trained to perform live shows alongside human actors for human audiences. Over the course of 30 performances to a combined audience of al...

Tricuspid paravalvular leak closure with a paravalvular leak device

A 69-year-old man, with a permanent pacemaker (PM) and a tricuspid bioprosthesis implanted 6 years ago, was admitted due to gradual exacerbation of heart failure symptoms to NYHA class III. Transthoracic (TTE) and transesophageal (TEE) echocardiography revealed proper function of bioprosthesis leaflets accompanied by the presence of severe paravalvular leak (PVL) with the PM lead crossing its c...

Clinical evaluation of improvised gauze-based negative pressure wound therapy in military wounds.

The use of negative pressure wound therapy (NPWT) in civilian and military wounds is found effective in promoting granulation tissue, decreasing exudate and improving patient comfort. The Use of gauze-based NPWT is increasing in civilian trauma cases with availability of proprietary systems using gauze as filler material rather than the traditionally used reticulated open-cell foam. Military tr...
