Abstract
A tissue displacement/separation device is provided. The device includes a bladder which is expandable between a first tissue and a second tissue of a body. The bladder has an expanded shape which is selected capable of displacing or separating the first tissue from the second tissue in a manner suitable for protecting the first tissue from an effect of a treatment applied to the second tissue.
Claims34
A method of forming a seamless bladder comprising:
- (a) providing a volumetric bladder template produced from hydrophilic material;
- (b) providing a solution of a polymer insoluble in water, the polymer being selected to biodegrade when inside a body over a period of weeks to months;
- (c) directly contacting an outer surface of the bladder template with the polymer solution to form a coating of the polymer directly on the bladder template outer surface to thereby generate a bladder having a thin layered seamless external surface made of said biodegradable polymer and a port with a diameter of between 1/100 and ⅕ of a diameter of said bladder;
- and
- (d) extracting said template through said port.

- (c) directly contacting an outer surface of the bladder template with the polymer solution to form a coating of the polymer directly on the bladder template outer surface to thereby generate a coat of said polymer directly on the bladder template outer surface;
- and
- (c) extracting said template through an orifice of said polymeric coat, and leaving said polymeric coat to form the seamless bladder.
