Abstract:
1. A method for manufacturing a catheter comprising a hydrophilic gel, said method comprising the steps of: a) combining a polymeric photoinitiator of the general formula I: wherein R R o and p are each a real number from 0-5000 provided that o+p>0; m and n are each a real number from 0-10, provided that m+n>0; r and s are each a real number from 0-5; provided at least one of m or n is at least 1; and A with one or more gel-forming polymers and/or gel-forming monomers to form a matrix composition, b) curing the matrix composition obtained in step a. by exposing it to UV radiation, c) exposing the matrix composition to a swelling medium, d) incorporating the hydrophilic gel/matrix composition into a catheter, wherein steps b) and c) may take place in any order, provided that, if step d) is carried out first, step b) takes place before step c).
