    摘要： A removable stent system and method for extraction of a removable stent from a target site is disclosed. The removable stent includes a removable stent having a collapsible end and a collapsing element configured for coupling with a removal tool. The collapsing element can be configured as a lasso or can be movable between two positions when deployed at a target site in vivo. The removable stent overcomes disadvantages and limitations of previous types of stents as well as overcoming complications during or following stent deployment in vivo. The removable stent further includes features that increase its ease of use and reduce the maneuvering required of devices or tools used to remove the stent. This then decreases the amount of effort required by the physician, the procedure time, and the level of discomfort experienced by a patient during the procedure.

    摘要： Method and surgical instrument for treating prostate tissue including a surgical instrument having a main body, a needle deployment port, a needle, first and second handles and a lockout release mechanism to limit needle extension. Additionally, a kit includes the surgical instrument, together with a cystoscope, and optionally a syringe and reservoir of ethanol. The method includes needle-less injection and visualizing the ethanol injection by delivering both an echogenic agent and ethanol either by needle or needle-less injection or by providing an ultrasonically visible marker near the tip of the ethanol delivery cannula. The method also includes extending the needle transversely of the instrument housing using a link assembly.

    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： A design and method of manufacture are disclosed for a female continence augmentor device used to alleviate urinary incontinence. The female continence augmentor includes a mount formed of a resilient material, an intralumenal part carried on the mount and a resilient portion carried on the intralumenal part of device. The mount adheres to the female body about the urethral exit to support the female augmentor into position to prevent inadvertent urine loss. The intralumenal part of the device extends from the mount into the urethral lumen at least to the mid-urethra. In particular, the resilient portion of the intralumenal part extends into the urethra and is adapted to at least urge the dorsal urethral wall in the dorsal direction to stretch and/or reshape the mid-urethral lumen to have a more arcuate shape. Thus, the mid-urethral lumen in cross-section would preferably exhibit a crescent shape of smaller radius. As such, the female continence augmentor enables a patient to void voluntarily with normal muscle control and without requiring conscious action to operate the device. Following voiding, the continence augmentation function of the device resumes automatically thereby increasing urethral resistance to opening and preventing inadvertent urine loss.
