Systems, methods, apparatus and devices for performing improved gynecologic and urologic procedures 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.

The present invention provides devices, methods and systems for the occlusion of various lumens in a body of a patient including devices and methods for enhancing tissue ingrowth, particularly endothelial tissue growth within an occlusive device. The system includes an occlusive device and a delivery device for placing the occlusive device in a body lumen. The occlusive device is generally a tubular member with a mesh member disposed thereon. The occlusive device is configured to be radially expandable along a longitudinal axis of the tubular member and implantable with a delivery catheter such that the occlusive device is in a collapsed state when positioned in the delivery catheter and in an expanded state when positioned in a lumen of a patient. The mesh member of the occlusive device is configured to promote epithelial tissue ingrowth.

The invention provides intrafallopian devices and non-surgical methods for their placement to prevent conception. The efficacy of the device is enhanced by forming the structure at least in part from copper or a copper alloy. The device is anchored within the fallopian tube by a lumen-traversing region of the resilient structure which has a helical outer surface, together with a portion of the resilient structure which is biased to form a bent secondary shape, the secondary shape having a larger cross-section than the fallopian tube. The resilient structure is restrained in a straight configuration and transcervically inserted within the fallopian tube, where it is released. Optionally, permanent sterilization is effected by passing a current through the resilient structure to the tubal walls.

Methods and apparatus of forming hydrogel systems in situ are provided using a delivery system configured to deliver two or more fluent prepolymer solutions without premature crosslinking. The delivery system comprises separate first and second lumens coupling first and second inlet ports and first and second outlet ports, respectively, and may include a balloon, flexible distal region, mixing chamber or steerable distal end. Multi-component hydrogel systems suitable for use with the inventive methods and apparatus are also described.

The invention provides intrafallopian devices and non-surgical methods for their placement to prevent conception. The efficacy of the device is enhanced by forming the structure at least in part from copper or a copper alloy. The device is anchored within the fallopian tube by imposing a secondary shape on a resilient structure, the secondary shape having a larger cross-section than the fallopian tube. The resilient structure is restrained in a straight configuration and transcervically inserted within the fallopian tube, where it is released. The resilient structure is then restrained by the walls of the fallopian tube, imposing anchoring forces as it tries to resume the secondary shape.

An absorbable and expandable closure member used to occlude or exclude a body lumen or cavity, such as a blood vessel, fallopian tube, duct, aneurysmal sac, etc., comprising a closure member comprising one of more sheets of a biomaterial that are rolled, stacked, or folded to form a multilayer construct of a generally cylindrical configuration for deployment through a delivery system, either as a singularly or part of a multiplicity of closure members. The biomaterial is derived from a source material, such as small intestinal submucosa or another remodelable material (e.g., an extracellular matrix) having properties for stimulating ingrowth of adjacent tissue into the biomaterial deployed within the bodily lumen. The closure member is deployed to the bodily lumen from a delivery sheath, cartridge, and / or over a inner guiding member, such as a wire guide or catheter.

An occlusion clip for permanently occluding a bodily vessel, such as the vas deferens. The occlusion clip has a first leg, a second leg, joined on their proximal ends by a spring coil. The spring coil provides a biased torsional force to the first leg and the second leg, to force them into a closed position. The first leg and the second leg have on their distal ends a vessel occlusion portion that occludes the targeted vessel when the clip is in a closed position.

An device for occluding a body lumen such as a reproductive lumen which includes an occluding component having an impervious barrier to provide initial occlusion of the body lumen and a permeable body to facilitate tissue ingrowth which provides long term occlusion of the body lumen. The device and the method of using the device is particularly suitable for contraception.

The invention described is directed to an intracorporeal occluding device having elements with non-traumatic ends and devices, systems and methods for occluding the lumens of anatomical passageways and / or for delivering drugs or other substances to the bodies of human or animal subjects.

A device and method of using the device for contraception or sterilization and particularly for reversible contraception by occluding a reproductive lumen to prevent the passage of reproductive cells through the lumen for a desired period of time until the patient wishes to become fertile again and then be reopened. The occluding member preferably comprises a tubular framework formed from a shape memory material configured to be implanted in a reproductive lumen. The occluding member is implanted within a body lumen, secured to the wall of the reproductive lumen and then collapsed to collapse the wall and occlude the lumen. Alternatively, the occluding member may be collapsed upon a solid plug. The closure of the reproductive lumen may be reversed by introducing a balloon catheter and by a series of inflations of the balloon reexpanding the collapsed occluding member or by removing the plug. The occluding member and the plug may be configured to facilitate endothelialization, to provoke an inflammatory responses or to deliver a drug.

Methods and devices for occlusion of the fallopian tubes of a woman. The method involves thermally damaging the lining of the utero-tubal junction with relatively low power, followed by placement of a reticulated foam plug. In one embodiment, vascularized tissue grows into the plug and prevents or discourages formation of scar tissue around the plug. Another embodiment with a relatively small foam pore size encourages formation of a vascularized capsule around the plug. The presence of this vascularized capsule limits the patient's foreign body response, so that the capsule does not constrict around the plug. Also presented is a catheter designed for wounding the epithelial layer of the utero-tubal junction, and a method of using the catheter to form a long yet shallow lesion in the utero-tubal junction.
