Abstract
Abstract The body of a patient is gaplessly coupled to the membrane of therapeutic equipment through a gel layer; a gel releasing bag is placed upon the membrane and the membrane is moved towards the body; subsequently, the bag is removed from the gap that forms between the skin of the patient and the membrane whereby gel emerges from one or several openings, filling the gap completely with gel as the bag is squeezed and removed.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
108 words
Method for air gaplessly coupling the body of a human being to the membrane of therapeutic shock wave equipment by providing on the body a gel layer through which shock waves are to be transmitted without attentuation, comprising: placing a gel releasing bag upon said membrane, the bag having at least one opening along one edge of the bag; moving the membrane towards said body; and removing said bag from the gap between the skin of the patient and the membrane whereby a gel layer emerges from said at least one opening along the one edge and fills the gap completely with gel as the bag is removed.
Claim 2
Dependent Claim
108 words
Method for air gaplessly coupling the body of a human being to the membrane of therapeutic shock wave equipment by providing on the body a gel layer through which shock waves are to be transmitted without attentuation, comprising: placing a gel releasing bag upon said membrane, the bag having at least one opening along one edge of the bag; moving the membrane towards said body; and removing said bag from the gap between the skin of the patient and the membrane whereby a gel layer emerges from said at least one opening along the one edge and fills the gap completely with gel as the bag is removed.
Claim 3
Dependent Claim
24 words
The method as in claim 1, and including squeezing the bag upon removing the bag from the gap between the body and the membrane.
Claim 4
Dependent Claim
26 words
The method as in claim 1 including the step of squeezing gel in multiple stream from multiple openings in the bag as the bag is removed.
