Problems solved by technology

[0005] For example, some medical devices require the user to wiggle or manipulate the medical device within the body cavity to spread the ablation; however, such wiggling or maneuvering may result in tissue perforation, user discomfort, may prolong the medical procedure, and / or may cause user fatigue
[0006] For example, some medical devices include electrode arrays; however; insertion of electrode arrays into body cavities presents a risk of tissue perforation
[0007] For example, some medical devices utilize fluid that circulates inside a single-walled balloon, however, circulating fluid inside a single-walled balloon presents a risk of fluid entering the body cavity if the balloon ruptures or leaks

Embodiment Construction

[0030] These teachings relate to medical devices. The medical device may be used to treat or affect an anatomical feature. The medical device may be configured to treat anatomical features by ablation. The medical device may be configured to affect or destroy anatomical features such as the endometrium through heat. The anatomical feature may be any anatomical feature, such as a body cavity or lumen. The body cavity may be the uterus. The medical device may be configured to treat menorrhagia.

[0031] Although the medical device disclosed herein may be used to treat menorrhagia, it should be understood that the medical device may also be used in other applications. For example, the device and system may be used to treat tissue in the bladder, vagina, esophagus, trachea, urethra, ureter, prostate, kidney, neoplastic or abnormal tissue of the intestine, cancerous tissue, and the like.

[0032] The medical device includes a handpiece. The handpiece may function to be held b...

Abstract

The invention relates to resistive heat ablation for treatment of the anatomy. A medical device includes an expandable member, a fluid lumen, and a heating element. The expandable member has an innerexpandable member and an outer expandable member. The fluid lumen is between the inner expandable member and the outer expandable member. The heating element is located inside of the fluid lumen.

Description

technical field [0001] These teachings relate to a medical device and method for treating anatomical structures. Background technique [0002] Menorrhagia is a medical condition that includes abnormally heavy and prolonged menstrual bleeding and pain. Hormonal drugs and / or hysterectomy have been used to treat menorrhagia for decades. [0003] Recently, medical devices have been introduced for the treatment of menorrhagia by ablation of the endometrium, where the endometrium is exposed to various treatment modalities such as radio frequency energy (RF energy) therapy, cryotherapy, thermal energy therapy, microwave energy therapy and / or or steam therapy. [0004] While generally effective, some medical devices include some disadvantages. [0005] For example, some medical devices require the user to wiggle or manipulate the medical device within the body cavity to diffuse ablation; however, such wiggling or maneuvering may result in tissue perforation, user discomfort, may ...
