Inflatable Device Stops the Bleeding

A fast, efficient balloon-based system could save lives on the street and battlefield.

Uncontrolled bleeding is a major cause of death on the battlefield, and according to military medical experts, it accounts for 80 percent of otherwise preventable deaths. One problem is that there are no effective treatments for deep, penetrating wounds, which are too severe for gauze packing and are in areas where a tourniquet cannot be applied. To stop life-threatening bleeding in such instances, Maynard Ramsey, the chief executive officer and chief technology officer at CardioCommand, a Tampa, FL-based medical device company, has developed a balloon-based system that can be inserted into a wound and inflated in less than 90 seconds.

Implant cancer fighting vaccine the size of a fingernail

cancer fighting implant

A polymer implant, 8.5 mm in diameter, is embedded with chemical signals that encourage immune cells to attack tumors.

In a world first, scientists have successfully eliminated tumors in mammals using a cancer vaccine carried into the body on a fingernail-sized implant. The new approach uses plastic disks impregnated with tumor-specific antigens and implanted under the skin to reprogram the mammalian immune system to attack tumors.

In a world first, scientists have successfully eliminated tumors in mammals using a cancer vaccine carried into the body on a fingernail-sized implant. The new approach uses plastic disks impregnated with tumor-specific antigens and implanted under the skin to reprogram the mammalian immune system to attack tumors.

Most cancer cells easily skirt the immune system, which operates by recognizing and attacking invaders from outside the body. The approach developed by bioengineers and immunologists at Harvard University redirects the immune system to target tumors, and appears both more effective and less cumbersome than other cancer vaccines currently in clinical trials.

Conventional cancer vaccinations remove immune cells from the body, reprogram them to attack malignant tissues, and return them to the body. However, more than 90 percent of reinjected cells die before having any effect in experiments.

The slender implants developed by the group measure 8.5 millimeters in diameter and are made of an FDA-approved biodegradable polymer. Ninety percent air, the disks are highly permeable to immune cells and release cytokines, powerful recruiters of immune-system messengers called dendritic cells.

These cells enter an implant’s pores, where they are exposed to antigens specific to the type of tumor being targeted. The dendritic cells then report to nearby lymph nodes, where they direct the immune system’s T cells to hunt down and kill tumor cells.

“Inserted anywhere under the skin – much like the implantable contraceptives that can be placed in a woman’s arm – the implants activate an immune response that destroys tumor cells,” said David J. Mooney the Robert P. Pinkas Family Professor of Bioengineering in Harvard’s School of Engineering and Applied Sciences and Wyss Institute for Biologically Inspired Engineering who led the research.

Camel Mobile Clinic Using Solar Power

solar camel

A system for transporting medicine to remote African communities blends affordable technologies with advanced engineering and design.

Some of the African country’s camels are carrying the solar-powered mini fridges on their backs as part of a test project that uses camels as mobile health clinics. Organizers hope the eco-friendly transport system will provide a cheap, reliable way of getting much-needed medicines and vaccines to rural communities

The Laikipia and Samburu districts in Kenya are isolated regions populated largely by nomadic peoples. The terrain is harsh and inhospitable, with few roadways, making travel difficult from urban centers. The local population, of around 500,000, suffers from high rates of illiteracy and poor health care. For the past decade, the Kenyan-based Nomadic Communities Trust (NCT) has sent camel convoys — the most efficient and cost-effective means of transportation — to the region with medical supplies. But poor equipment (basically, wooden boxes tied to the camels with abrasive sisal rope) and lack of refrigeration meant that basic medicines such as vaccines could not be made available.

The project, which could be fully implemented in 2010 if necessary funding is secured, blends relatively affordable technologies with advanced engineering and design. It was devised with a budget of a few thousand dollars and staff from Art Center and Princeton, which was critical because the project was not selected to receive assistance from the World Bank. “We created this project without having to send a team of 20 people back and forth to Kenya for field research.
