摘要： A flexible cytoscope having an injection device with a cross-sectional profile allowing for irrigation flow without the risk of buckling or lateral deflection of the injection device. The cross-sectional profile is configured such that the injection device is constrained by the cytoscope lumen. The cross-sectional profile of the injection device can be formed integrally with the injection device or can alternatively comprise a secondary structure that is attached about an exterior portion of the injection device. The cross-sectional profile can be present at intervals along the length of the injection device or can extend the entire length of the injection device. The injection device can be configured such that the cross-sectional profile centers the injection device within the cytoscope lumen or in an off-set or non-centered position depending upon the treatment being performed.

摘要： A female continence augmentor stops involuntary urine loss due to transient increases in bladder pressure but allows urine flow when automatically opened by transmitted bladder pressure during voluntary voiding. The augmentor improves coaptation and increases midurethral resistance to opening with a resilient mount releasably adhered adhesively to the body in position to prevent inadvertent urine loss. An intralumenal part on the mount has a resilient portion extending into the urethra for urging the dorsal midurethral wall in a dorsal direction for stretching and/or reshaping the midurethral lumen to an arc. The portion has a member located to engage the midurethral wall. A coaptation improver on the member engages with the adjacent midurethra. The improver carries biocompatible hydrophilic material adapted to coact with mucus and mucosa within the urethra. A coated biocompatible hydrophilic membrane can be the member with opposed generally rectangular major surfaces and is circumscribed by an edge. The hydrophilic membrane is bowed along the edge transverse between sides thereof for bearing against the inside of the midurethral walls. The membrane has a mesh of flexible polymer and an arc shape between the sides so the opposed major surfaces are concave and convex. Two struts can extend from the sides to the portion. A method of making the augmentor has the steps of forming the mount of resilient material. The resilient material adheres to the body to support the augmentor in position to prevent inadvertent urine loss through the midurethral lumen. The part on the mount extends into the urethra. Connecting the part to the mount and locating the member on the portion for placement relative to the mount intralumenally is a step. The method step of forming includes molding the mount of a polymer. The step of locating the member uses at least one or two struts. The method has the step of adding an adhesive to the mount and increasing coaptation of the portion with a material. A method of using the augmentor has the steps of inserting the part into the urethra so that the member is within the midurethral lumen and placing the mount adjacent to the urethral exit to retain the member therein. Applying resistance inside the urethra with the member by the portion is a step of using. Urging the dorsal midurethral wall in a dorsal direction and engaging the urethral wall, especially the midurethral wall to remove laxity therein are steps of using.

摘要： The tissue approximating structures for the anastomosis devices of the invention preferably include two sets of approximating structures or tines spaced from each other along the length of a catheter body that can be extended and retracted from the catheter body. Each of the sets of tissue approximating structures is preferably sequentially deployable in such a way that the surgeon can activate a first set of tines to engage a first tissue structure, verify that an adjacent second tissue structure is properly positioned relative to the first tissue structure, then activate a second set of tines to engage that adjacent second tissue structure. Each of the sets of tines is preferably controlled by a single actuation mechanism that is attached to the anastomosis device and is positioned outside the patient's body.
