Method and device for distending a gynecological cavity. According to one embodiment, a mechanical, non-fluid device is used to distend the gynecological cavity. Such devices include, for example, self-expanding members, such as resilient baskets, coils, whisks, prongs, and loops, or mechanically expanded members, such as inflatable balloons, mechanically-expanded cages and loops, and scissor jacks. The device may serve a purpose in addition to distension, such as illumination, imaging, irrigation, drug delivery, resection and cauterization.

The invention is directed to an endoscopic assembly having an endoscope, particularly a flexible hysteroscope and an outer sheath disposed about a length of the shaft of the hysteroscope which has an expandable member such as an inflatable balloon for sealing the assembly within a body lumen or cavity. Specifically, the endoscope assembly is configured for delivery of an occlusive contraceptive member to the patient's fallopian tube. The invention is also directed to an endoscope having a driving member for movement of a medical device within the working lumen of an endoscope. In one embodiment the driving member is a friction wheel which engages an elongated medical device disposed within the working channel of the endoscope to effect longitudinal movement of the medical device.

The present invention comprises systems, methods and devices for the delivery of compositions for occluding or of means for opening conduits. The implantable occlusive material may be delivered pre-formed or in situ cured and, may be a resorbable material that supports tissue ingrowth that eventually replaces the material leaving little or no original material in place. The delivery system is positioned to allow for placement of the occlusive material into the body conduit. Use of delivery systems, methods and devices for re-opening an occluded body conduit are also included.

The present invention comprises systems, methods and devices for the delivery of visualizable or treatment compositions or therapeutic agents comprising device elements for diagnosis and/or treatment of conduits. A delivery system comprising an introducer shaft having at least one exit port and at least one delivery catheter for placement of compositions into the conduit, such as a fallopian tube.

A system for performing a medical procedure and an introducer device suitable for use in the system. The system may be used, for example, to examine and/or to treat the uterus. According to one embodiment, the system includes an introducer, a morcellator, a flexible hysteroscope, and a fluid-containing syringe. The introducer is suitable for transcervical insertion into the uterus and includes a gun-shaped housing and a rigid sheath extending distally from the housing. The sheath is shaped to include an instrument lumen, a visualization lumen, and a pair of fluid lumens. The introducer also includes a first assembly within the housing for receiving the morcellator and for guiding the distal end of the morcellator into the instrument lumen and a second assembly within the housing for guiding the hysteroscope into the visualization channel. In addition, the introducer further includes an assembly for fluidly connecting the syringe to the fluid lumens.

Systems, methods, apparatus and devices for performing improved gynecologic and urologic procedures using a flowable distension media are disclosed. The system and devices provide simplified use and reduced risk of adverse events. Patient benefit is achieved through improved outcomes, reduced pain, especially peri-procedural pain, and reduced recovery times. The various embodiments enable procedures to be performed outside the hospital setting, such as in a doctor's office or clinic.

Methods, systems and devices for performing gynecological procedures. According to one embodiment, there is provided a device for occluding a fallopian tube, the device including an outer member and an inner member. The outer member may be a hollow, frusto-conical structure shaped to include an open proximal end, an open distal end, and a side wall. The outer member may be self-expandable such that the distal end is biased radially outwardly. In addition, the side wall may have a porous structure to permit the ingrowth of tissue therethrough. Tines may be provided on the outer surface of the side wall to promote the anchoring of the outer member in a fallopian tube. The inner member, which may be structured to induce scarring, may comprise an elongated fibrous body fixed at its proximal end to the proximal end of the outer member. A bore may extend distally from the proximal end of the inner member to receive a delivery rod. The inner member, which may have pores or interstices to permit the ingrowth of tissue thereinto, is coated or impregnated with a sclerosing agent.

This invention is directed to occluding devices and methods of using such devices for occluding a patient's body lumen, such as a reproductive lumen for contraceptive purposes. The occluding device generally has an occluding component, a first metallic element associated with the occluding component, a second metallic element associated with the occluding component. The first and second metallic elements are configured to generate electrical activity which enhances tissue growth into and/or onto the occluding component to aid in lumen occlusion. In one embodiment the first and second metallic elements are formed of different metallic materials and generate galvanic activity. In a second embodiment electrical power is applies to the first and second metallic elements to generate electrical activity that enhances tissue growth.

The various embodiments of the present inventions provide stabilization devices and methods for use of the stabilization devices with minimally invasive gynecological procedures such as methods of preventing pregnancy by inserting intrafallopian contraceptive devices into the fallopian tubes

Devices, such as medical devices for inhibiting conception, and methods of using and/or making these devices. In one aspect of the disclosure, a medical device has a delivery system and a first insert, which is removably coupled to the delivery system and which is designed to be deployed within a portion of a first fallopian tube, and a second insert, which is removably coupled to the delivery system and which is designed to be deployed within a portion of a second fallopian tube. Other aspects of the disclosure include, among other things, inserts made from one or more polymers; inserts which are designed to pierce and remain in place; and inserts which are implanted through a fluid delivery system.

A contraceptive device for placement in a fallopian tube includes expanding distal and proximal anchor members and an expandable elongate member connecting the distal anchor member to the proximal anchor member. An expandable material is disposed on at least a portion of the contraceptive device, whereupon delivery of the contraceptive device, the expandable material expands to completely occlude the fallopian tube. The expandable material may contain a drug, therapeutic agent, or hormone which is released over time to occlude or otherwise prevent the passage of spermazoa through the fallopian tube, or prevent ovulation. The contraceptive device may be delivered non-operatively and provide complete sterilization within a period of days. The device and delivery method obviates the need for follow-up visits to confirm closure of the fallopian tubes.

The present invention provides systems and methods for occluding and/or embolizing a cavity within a patient by delivering a prepolymer material into or onto a cavity and forming an expanding foam within the cavity. The inventions methods are applicable to occluding a variety of cavities, including blood vessels, aneurysms, left arterial appendages, vascular malformations and the like.
