Abstract
A modified membrane material, including a conductive surface, which may be used for a variety of medical or other applications, is provided. Various devices can be formed of the conductive surface materials, including tubes, probes, catheters and the like. Activation of the conductive surface, such as by connection to a suitable energy source, enables electrical current to be passed into a body region or to a device (e.g., a container) useful in holding and/or treating other materials.
Claims6
A probe for insertion into a body orifice comprising:
- a tube having first and second open ends;
- a polytetrafluoroethylene membrane, said membrane having a first end and a second end, wherein said first end of said membrane is interior of said tube and said second end of said membrane exterior said tube;
- a conductive ribbon proximate to said membrane;
- and
- a guide assembly connected to said membrane;
- wherein said membrane and said ribbon are inverted over said first open end of said tube.
A probe system useful for inserting a probe into a body cavity, said system comprising:
- a probe having first and second ends and a hollow body spanning therebetween;
- an unfolding sheath comprising a polytetrafluoroethylene resin, said sheath having first and second ends, said second end of said sheath initially contained within said hollow body of said probe, said sheath further being provided with a conductive path, said sheath configured such that when said probe is inserted into the body cavity, said sheath is withdrawn from said hollow body and interposed between the cavity and said probe along an exterior of said probe as said probe is inserted into the cavity, and
- a guide attached to said first end of said sheath, said guide and first end being disposed about the exterior of said probe first end.
