The Polyurethane Advantage.Because Better Care, Should Be Felt By Patients
A silicone-free alternative for patients requiring a polyurethane gastrostomy option polyurethane-based Gastrostomy button, the only alternative to silicone devices, combining comfort, robustness and longevity.
Hoist Medical has innovated the simple silicone button and developed the only polyurethane balloon button, offering all the benefits of polyurethane PEG in a convenient, easy-to-use low-profile button.
"Polyurethane PEG catheters seem to be more resistant to deterioration than silicone PEG catheters, and at present they should be preferred for long-term enteral feeding via PEG." 1
PURFIT™ Oblong Balloon Technology
The Shape of Protection. The Confidence of PURFIT™
Inspired by the timeless symbolism of the oblong form, and designed around the principles of protection, continuity and security, PURFIT™ combines intelligent balloon geometry with purposeful engineering and the performance advantages of polyurethane.
The PURFIT™ oblong balloon profile is engineered to support a secure, stable fit, helping minimise unwanted movement around the stoma site and reduce leakage. This helps limit exposure of surrounding skin to gastric contents, supporting improved peristomal skin protection.

A pivotal clinical decision to transform the patient care experience
“I was managing a medically complex patient battling relentless Candida infections. Every silicone gastrostomy tube we placed ended the same way — fungal colonisation visibly degrading the tube and often making it impossible to deflate the balloon.
Tube removals became painful and traumatic, with fungal biofilm encrusting the balloon and compromising the integrity of the silicone itself.
Despite prescribing multiple courses of fluconazole, the cycle of failure, leakage, and patient discomfort continued.
Switching to the PURFIT polyurethane button was a game-changer. Within weeks, visual assessments of the tube showed no signs of fungal colonisation, stoma leakage had resolved completely, and the site exhibited clear evidence of healing — all achieved without the need for further pharmacological intervention. Most importantly, the patient experienced meaningful relief from repeated procedures and discomfort, significantly improving their overall care experience.
It was a rare and rewarding outcome to eliminate both the recurrent infection and the ongoing device-related complications with a single, effective clinical choice.”

The gastrostomy button is a device held in the stomach by an inflated balloon. A gastrostomy is a connection from the stomach to the skin, through a tube or button. It allows "enteral feeding" to be administered directly into the stomach, duodenum or jejunum.
The choice of size and type of gastrostomy feeding tube will depend on a number of factors, including the expected duration of feeding, the reason nutrition or access to the digestive tract is required, and the patient's condition and anatomy.
A low-profile or "button" gastrostomy device is the most commonly used and preferred by patients because of the discretion it offers. Unlike PEG or G tubes, there are no long tubes to snag on clothing during physiotherapy sessions or daily activities.
The tube may be changed without any invasive procedures or return to hospital, (depending on local services) which can often be traumatic and challenging for both patients ans carers.
