Abstract
A technique for localized thermal therapeutic treatment of mammals comprising the steps of inserting a catheter through a urethra, the catheter including a first elongate portion including first and second passageways for circulation of a heated fluid and a plurality of sealed elongate enclosures which contain trapped gas and provide thermal insulation surrounding the first and second passageways and a second portion void of insulation extending from the first elongate portion with extensions of the first and second passageways therethrough; and circulating a heated fluid through the first and second passageways to provide desired therapeutic heating of the body tissue surrounding the second portion by thermal dissipation from the surface thereof.
Claims21
A catheter comprising:
- a first elongate portion including first and second passageways are in fluid communications with each other for circulation of a heated fluid and thermal insulation surrounding the first and second passageways, said thermal insulation comprising a plurality of sealed elongate enclosures which contain trapped gas;
- and
- a second elongate portion communicating with the first elongate portion and including extensions of the first and second elongate passageways therethrough and a flexible thermally transmissive wall the interior of which communicates with the extensions of the first and second elongate passageways.
A catheter comprising:
- a first elongate portion including first and second passageways are in fluid communication with each other for circulation of a heated fluid;
- and
- thermal insulation surrounding the first and second passageways, said thermal insulation comprising a plurality of sealed elongate enclosures which contain trapped gas;
- and
- a second elongate portion communicating with the first elongate portion and including extensions of the first and second elongate passageways in thermal contact with an exterior surface of the second elongate portion.
A technique for localized thermal therapeutic treatment of mammals comprising the steps of:
- inserting through a urethra, a catheter including a first elongate portion including first and second passageways are in fluid communication with each other for circulation of a heated fluid and a plurality of sealed elongate enclosures which contain trapped gas and provide thermal insulation surrounding the first and second passageways and a second portion void of insulation extending from the first elongate portion with extensions of the first and second passageways therethrough;
- and
- circulating a heated fluid through the first and second passageways to provide desired therapeutic heating of the body tissue surrounding the second portion by thermal dissipation from the surface thereof.
A technique for localized thermal and pressure therapeutic treatment of a body portion comprising the steps of:
- inserting through a urethra, a catheter including a first elongate portion including first and second passageways are in fluid communication with each other for circulation of a heated fluid and a plurality of sealed elongate enclosures which contain trapped gas and provide thermal insulation surrounding the first and second passageways and a second portion extending from the first elongate portion and including extensions of the first and second passageways therethrough and a flexible thermally transmissive wall void of insulation;
- and
- circulating a heated fluid through the first and second passageways under a suitable pressure to provide desired expansion of the wall of the second portion thereby to achieve a desired therapeutic application of pressure to the body tissue surrounding the second portion and therapeutic heating of the body tissue surrounding the second portion by thermal dissipation from the surface thereof.
A technique for localized therapeutic thermal and pressure treatment of prostate or bladder conditions or urethral strictures comprising the steps of:
- inserting through a urethra, a catheter including a first elongate portion including first and second passageways are in fluid communications with each other for circulation of a heated fluid and thermal insulation surrounding the first and second passageways, said thermal insulation comprising a plurality of sealed elongate enclosures which contain trapped gas;
- and a second portion extending from the first elongate portion with extensions of the first and second passageways therethrough, wherein the extensions of the first and second passageways communicate with the interior of the exterior wall of the second portion which is void of insulation to allow thermal dissipation from the surface thereof to the surrounding body tissue;
- and
- circulating a heated fluid through the first and second passageways under a suitable pressure to provide desired expansion of the exterior wall of the second portion thereby to achieve a desired heating and application of pressure to the body tissue surrounding the second portion.
