For example, the end-of-line production defect rate for the tiny catheters (flexible tubes) used for treating patients with cardiovascular disease is as high as 80%.
%The greater accuracy during manufacturing paves the way for the production of even smaller catheters to tackle blood-flow problems in harder-to-reach places of the body.

#Simple alerts can cut infections from catheters University of Pennsylvania rightoriginal Studyposted by Lee-Ann Landis Donegan-Penn on August 26 2014simpler automatic alerts in electronic health
records can cut the number of urinary tract infections in patients with urinary catheters report researchers. The alerts help physicians decide
whether their patients need urinary catheters in the first place and then alert them to reassess the need for catheters that have not been removed within a recommended time period.
Approximately 75 percent of urinary tract infections acquired in the hospital are associated with a urinary catheterâ##a tube inserted into the bladder through the urethra to drain urine.
According to the Centers for Disease Control and Prevention 15 to 25 percent of hospitalized patients receive urinary catheters during their hospital stay.
As many as 70 percent of urinary tract infections in these patients may be preventable using infection control measures such as removing no longer needed catheters resulting in up to 380000 fewer infections and 9000 fewer deaths each year.##
##First electronic alerts do result in fewer catheter-associated urinary tract infections. Second the design of the alerts is very important.
By making the alert quicker and easier to use we saw a dramatic increase in the number of catheters removed in patients who no longer needed them.##
##Fewer catheters means fewer infections fewer days in the hospital and even fewer deaths. Not to mention the dollars saved by the health system in general.##
##In the first phase of the study two percent of urinary catheters were removed after an initial##off-the-shelf##electronic alert was triggered (the stock alert was part of the standard software package for the electronic health record.
and used a simplified alert based on national guidelines for removing urinary catheters they had published previously with the CDC.
Following introduction of the simplified alert the proportion of catheter removals increased more than sevenfold to 15 percent.
The study also found that catheter associated urinary tract infections decreased from an initial rate of. 84 per 1000 patient days to. 70 per 1000 patient-days following implementation of the first alert and. 50 per 1000
Among other improvements the simplified alert required two mouse clicks to submit a remove-urinary-catheter order compared to seven mouse clicks required by the original alert.
In patients electronic health records physicians were prompted to specify the reason (among ten options) for inserting a urinary catheter.
On the basis of the reason selected they were alerted subsequently to reassess the need for the catheter
Women s health units had the highest proportion of alerts that led to a remove-urinary-catheter order

#A Light-Reflecting Balloon Catheter Repairs the Heart without Surgery Harvard-affiliated researchers have designed a specialized catheter for fixing holes in the heart by using a biodegradable adhesive and patch.
The team reported in the journal Science Translational Medicine that the catheter has been used successfully in animal studies to help close holes without requiring open-heart surgery.
Their catheter device utilizes UV-light technology and can be used to place the patch in a beating heart.
The catheter is inserted through a vein in the neck or groin and directed to the defect within the heart.
Once the catheter is in place, the clinician opens two positioning balloons: one around the front end of the catheter, passing through the hole,
and one on the other side of the heart wall. The clinician then deploys the patch and turns on the catheter UV light.
The light reflects off of the balloon shiny interior and activates the patch adhesive coating.
and the catheter is withdrawn. Over time, normal tissue growth resumes, and heart tissue grows over the patch.

"Patients often can't insert a catheter to empty their bladders or insert a suppository for bowel movement and have to rely on help from a caregiver.

UV-light enabled catheter fixes holes in the heart without invasive surgery Researchers from Boston Children Hospital, the Wyss Institute for Biologically Inspired Engineering at Harvard university,
Harvard John A. Paulson School of engineering and Applied sciences (SEAS) and the Karp Lab at Brigham and Women Hospital have designed jointly a specialized catheter for fixing holes in the heart using a biodegradable adhesive and patch.
As the team reports in Science Translational Medicine, the catheter has been used successfully in animal studies to facilitate hole closure without the need for open heart surgery.

Both procedures are performed by snaking catheters, typically from a blood vessel in the groin, up to the diseased valve.
#Graphene-Coated Catheters May Improve Delivery of Chemotherapy drugs The research suggests that placing graphene-an extremely thin sheet of carbon atoms-on the internal surfaces of intravenous catheters commonly used to deliver chemotherapy drugs into a patient's body will improve the efficacy of treatments,
and reduce the potential of the catheters breaking. The study indicates that damaging interactions can occur between the most commonly used chemotherapy drug, 5-Fluorouracil (5-Fu),
and the materials they routinely come into contact with, such as catheters and needles and their coatings.
"As a solution to this problem, the international team of researchers have proposed using graphene as an alternative coating material for catheters.
