Angiography Sling

The Problem

When a patient undergoes coronary angiography, a catheter is inserted into the cardiovascular system, guided around the aorta and subsequently located into the coronary arteries feeding the heart. When the catheter is in the correct position, X-ray contrast is injected into the coronary arteries. The catheter can be inserted into a femoral or radial artery, however radial is preferred as evidence shows that it is less painful for the patient, recovery time is shorter and the patient is less likely to require a bed overnight.

The configuration of the angiography theatres are such that the surgeon stands to the right of the patient and the X-ray equipment and monitors are located on the left of the patient. As a result, arterial access is generally gained from the right. However, in cases where left radial approach is necessary, for example when there are problems with right radial access or when the patient has had coronary artery bypass grafting, the positioning of the X-ray equipment and monitors means the surgeon must remain standing on the right of the patient and lean over the patient to position the catheter into the left artery. This does in many cases causes the surgeon to use a femoral approach rather than a radial approach and can result in an increase in discomfort and time in hospital for the patient.

The Solution

The invention is a disposable sling which supports the left arm in a position over the trunk. This will enable the surgeon to complete a left radial approach without leaning over the patient and prevents the arm from slipping. The angiography sling comprises a clip that will  attach to the patient bed and a sling to hold the arm in place. The product is a disposable item that will comply with hospital infection control regulations. The angiography sling is currently under licence to G Med UK and will shortly be available to purchase.

Benefits to the NHS

The sling provides comfort for both the patient and the operator and reduces the need for a femoral artery approach with its associated increase in recovery periods.  The sling will enable an increase in radial approach angiographies and cost saving to the NHS through reduced recovery times.
