摘要: Apparatus and methods for performing surgery within a hollow-body organ are provided. A catheter is provided having a longitudinal axis and an end region carrying an end effector. The end region is movable to a series of positions along the longitudinal axis with a selectable orientation relative to the longitudinal axis. The catheter includes elements for stabilizing the end region of the apparatus within a hollow-body organ, and for counteracting reaction forces developed during actuation of the end effector. The end effector provides for tissue cutting and aspiration of severed tissue from a treatment site.

摘要: Cervical dam for capturing liquid draining from uterus during gynecological procedures while simultaneously providing an aperture through the cervical dam for insertion and manipulation of a medical device. The aperture may be a preformed slit elastomeric aperture, a duck billed valve, a multi-disc elastomeric valve, or a universal seal. The cervical dam includes a drainage port through the body of the cervical dam, a drainage tube attached to the drainage port, and a handle, which may be detachable, affixed to the cervical dam for placement, manipulation and removal of the cervical dam. Also disclosed are methods for performing a gynecological procedure by placing a cervical dam over the cervical canal inserting a medical instrument through the cervical dam into the cervical canal, performing a procedure, and withdrawing the medical instrument, and by determining the amount of fluid input to a patient during the procedure and the amount drained from the patient during and after the procedure, and comparing the two.

摘要: An apparatus for thermal coagulation and more particularly to a system for applying heat to the endometrium of a human uterus of the type comprising a heated balloon catheter having a reciprocating piston for improved circulation of fluid within a distensible bladder. The present invention includes a heated balloon catheter having a fluid delivery tube connected to a distensible bladder. The catheter further includes a reciprocating piston which moves along a linear path within the distensible bladder to cause vigorous fluid agitation therein. The agitation caused by the piston efficiently mixes the fluid within the balloon without requiring hot fluid to circulate through the fluid delivery tube.

摘要: Electrophysiology mapping and visualization systems are described herein where such devices may be used to visualize tissue regions as well as map the electrophysiological activity of the tissue. Such a system may include a deployment catheter and an attached hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to a region of tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid, such as saline, can be pumped into the imaging hood until the fluid displaces any blood, thereby leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. A position of the catheter and/or hood may be tracked and the hood may also be used to detect the electrophysiological activity of the visualized tissue for mapping.
