Abstract
A slit valve (10) for use with an inflatable medical device having a flange surface (12) with an opening therein. The slit valve (10) has a valve body (14) connected to the flange surface (12) and a chamber formed in the valve body (14) for accepting an inflation tube (34) inserted through the opening in the flange surface (12). The slit valve (10) has a concave section at one or both ends, which are connected by a slit (24) formed in the valve body (14).
Claims35
A slit valve comprising:
- a flange surface having an opening therein;
- a valve body having proximal and distal ends, said proximal end connected to said flange surface;
- a first chamber formed in said valve body for accepting an inflation tube inserted through said opening in said flange surface;
- a concave section located adjacent said first chamber;
- and
- a slit formed in the valve body connecting said concave section and said distal end.
An implantable, inflatable apparatus comprising:
- a slit valve, wherein said slit valve includes a flange surface having an opening therein, a valve body having proximal and distal ends, said proximal end connected to said flange surface, a first chamber formed in said valve body for accepting an inflation tube inserted through said opening in said flange surface, a concave section adjacent said first chamber, and a slit formed in the valve body connecting said concave section and said distal end.
A medical apparatus for the treatment of obesity comprising:
- an inflatable balloon formed of a suitable polymer material for insertion into the stomach;
- a slit valve for communication of a fluid from an inflation tube to said balloon, wherein said slit valve includes a flange surface having an opening therein, a valve body having proximal and distal ends, said proximal end connected to said flange surface, a first chamber formed in said valve body for accepting the inflation tube inserted through said opening in said flange surface, a concave section located adjacent said first chamber, and a slit formed in the valve body connecting said concave section and said distal end.
A two-way valve having first and second ends comprising:
- a cylindrical valve body;
- a slit formed in said valve body connecting the first and second ends of the two-way valve;
- and
- a concave section formed on the first and second ends and connected by said slit.
