#UV Catheter Plugs Holes in Hearts With help from UV LIGHT, a new catheter device could provide a way to repair defects in hearts and other organs without surgery.
The catheter is inserted through a vein in the neck or groin and directed to the area of the defect.
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 organ wall. The clinician then deploys the patch and turns on the catheter's UV LIGHT.
The light reflects off of the balloon's shiny interior and activates the patch's adhesive coating.
and the catheter is withdrawn. Over time, tissue grows over the patch and it dissolves.""This really is a completely new platform for closing wounds

This self-balancing wheelchair can climb and descend stairs automatically Stairs and uneven ground surfaces pose a huge problem for wheelchair users,
and while ramps can improve accessibility, theye costly to implement and not always easy to retrofit to existing building structures.
Fortunately, students in Switzerland have answered this very problem with the calevo an electric wheelchair that has the ability to ascend steps directly by lowering a tank-style tread that can roll the wheelchair up a flight of stairs.
the Scalevo features gyroscopic technology that lets the wheelchair automatically balance itself on just two wheels
the wheelchair turns around and ascends the steps backwards via the caterpillar track. he great thing is that everything on this wheelchair is automated,
said Miro Voellmy, who helped design the wheelchair frame and support system, as reported by Jim Drury at Reuters. f
I want to climb the stairs I can just drive up to them, turn around, press one button and all
In addition to letting the wheelchair climb stairs, the track mechanism can also significantly raise the height of the user to give the person operating the chair a more elevated view of things when on flat surfaces.

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.
Their newly designed 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,

But it is able to adjust the amount of power the prosthesis receives in real time, in order to maintain the proper angle.

Our team is now considering how to incorporate this device into a catheter that could siphon out cerebral spinal fluid
An endoscope is inserted through one or two small incisions in the abdominal wall allowing the internal organs to be visualized for surgery.
The same cannot be said for surgical instruments. In certain types of endoscope, the tip can be oriented at different angles."
"This basic control mechanism, which demands great dexterity and even physical strength on the part of the surgeon, has changed barely
Modern endoscopes are equipped additionally with tiny pincers, clamps or scissors for removing tissue samples, for example.
The cable mechanism transmits the surgeon's hand movements at one end to the tiny instruments at the other extremity of the endoscope.
To control the attached instruments and orient the tip of the endoscope, the surgeon manipulates a hydraulic cylinder
using both rigid endoscope tips and simple gripping tools. Laboratory prototypes with flexible tips have also been tested.
In January 2013 a Swedish arm amputee was the first person in the world to receive a prosthesis with a direct connection to bone, nerves and muscles.
Before the surgery, his prosthesis was controlled via electrodes placed over the skin. Robotic prostheses can be advanced very,
The patient is also one of the first in the world to take part in an effort to achieve long-term sensation via the prosthesis.
"Reliable communication between the prosthesis and the body has been the missing link for the clinical implementation of neural control and sensory feedback,
Today, no patient walks around with a prosthesis that provides such information, but we are working towards changing that in the very short term."
"The new technology is based on the OPRA treatment (osseointegrated prosthesis for the rehabilitation of amputees),
where the prosthesis is fixated then. Electrodes are implanted in nerves and muscles as the interfaces to the biological control system.
and easy attachment/detachment Increased sensory feedback due to the direct transmission of forces and vibrations to the bone (osseoperception) The prosthesis can be worn all day,
Due to the intimate connection, the patients can control the prosthesis with less effort and more precisely,
and still maintain control of the prosthesis. More motor signals can be obtained from muscles and nerves,
so that more movements can be controlled intuitively in the prosthesis. After the first fitting of the controller, little or no recalibration is required
because there is no need to reposition the electrodes on every occasion the prosthesis is worn (as opposed to superficial electrodes).
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.

The experimental pill works in the same way as gastric pacemakers to suppress appetite. A gastric pacemaker is an implant that is surgically placed in the stomach and wired to the vagus nerve.
This nerve carries signals from the stomach to the hypothalamus, the area of the brain responsible for regulating appetite.
The pacemaker has a sensor that detects when food is entering the stomach. It then fires low-level electrical pulses into the vagus nerve to fool the brain into thinking the stomach has no more room.
Gastric pacemakers cost around £10, 000 and are reserved usually for patients who don't respond to dieting,
