Medtronic (NYSE: MDT), maker of cardiac management devices, has had ups and downs recently. Recently, Medtronic's remote heart monitor failed a crucial FDA evaluation. The size of an old-fashioned pocket watch, Medtronic's new device, called the Chronicle implantable hemodynamic monitor, was to be used for cardiac monitoring once implanted in patients who had already experienced one heart attack. The device would send cardiac information to doctors who could then monitor patients remotely. In the event of warning signals, doctors could direct patients to get to the hospital prior to experienceing a second cardiac event so that immediate preventive treatment could be started. The point of the device was to reduce the severity of additional cardiac events before they happened, thus reducing both the length and cost of hosptial stays. Medtronic estimated that close to 10% of all heart patients in the US, half a million people, could benefit from such a monitoring and early warning implant. The clinical trial involved just 274 patients. The FDA reluctantly concluded, voting 9-2, there was not enough evidence of reductions in hospitalizations to justify approving the device at this time. Several cardiologists on the panel encouraged Medtronic to continue developing implantable cardiac monitoring devices.

Despite the recent setback, Medtronic CEO Art Collins remains optimistic that Medtronic's interactive patient monitoring devices will eventually gain FDA approval. Medtronic released 3Q 2007 results earlier this month. 3Q revenue was up 10% to just over $3 billion, with EPS up 17%. Fully a third of Medtronic revenue was from outside the US. Almost half of Medtronic's total revenue comes from cardiac devices, down from two-thirds several years ago. Medtronic has branched out to target ear, nose and throat devices, insulin pumps and glucose monitors for diabetes patients, as well as stents and artificial valves used in cardiac surgery.

Currently, Medtronic has more than 200 clinical trials underway, including an artificial spinal disk trial in the US. More than 200,000 patients in the US are potential recipients for such replacement disks each year. Medtronic's R&D budget tops $1 billion per year. The company holds 8,000 active patents.

Pfizer (NYSE: PFE) is looking for additional uses for its popular drug Viagra in order to keep up sales when its patent expires in a few years. One possible use for Viagra is being studied at Henry Ford Hospital in Detroit. The study is to determine whether patients who have suffered moderate strokes will recover more rapidly if given Viagra within 7 days of stroke symptoms. Can the brain on Viagra form new blood vessels and nerve connections better than without Viagra?

In another clinical trial, Viagra, repackaged in white (not blue) 20 milligram pills and renamed Revatio, is used to treat pulmonary hypertension, a lung disorder affecting both adults and children. So we should give our kids a form of Viagra with their Flintstones vitamins? Pfizer has come under some criticism for the cost of Revatio compared to that of Viagra. Taken 3 times per day as Revatio, the drug costs $33.50 per day or over $11 per 20 milligram pill. Taken as Viagra in 100 milligram doses, the drug costs just over $11 per pill. Pfizer argues that the 20 milligram pill costs as much as the 100 milligram pill because of the increased costs to gain federal approval for use in an entirely new group of patients.

Viagra is also being studied for possible use in treating high blood pressure in pregnant women and to ease menopause symptoms. This last use has been challenged recently, particularly by a group of women in Utah. According to an article by Brooke Adams in The Salt Lake Tribune, at least 75 women have joined together to form a class action suit against Pfizer. The women claim that taking Pfizer's Provera, synthetic progesterone, to control menopause symptoms caused them to develop breast cancer.
