摘要:
The present invention relates to devices for closing a passageway in a body, for example a patent foramen ovale (PFO) in a heart, and related methods of using such closure devices for closing the passageway. The method includes introducing a mechanical closure device into an atrium of the heart and transeptally deploying the closure device across the interatrial septum to provide proximation of the septum secundum and septum primum.

The present invention relates to a delivery system for delivering a device for closing a passageway in a body, for example a patent foramen ovale (PFO) in a heart. The delivery system has an elongate member having a proximal and distal end. A deflectable needle assembly having luminal and abluminal surfaces is slideably engaged within the elongate member. An actuator is slideabley engaged within the elongate member and attached to the needle tip assembly such that translational movement of the actuator causes deflection of the deflectable needle assembly.

A device for deploying a mechanical closure device for closing a passageway in a body, for example a patent foramen ovale (PFO) in a heart. The deployment device has a first tubular structure having proximal and distal ends. A second tubular structure is substantially coaxial to and slideably engaged within the first tubular structure. The second tubular structure has a first substantially linear shape when constrained within the first tubular structure, and a second curvilinear shape when telescopically extended from the distal end of the first tubular structure. A third tubular structure is substantially coaxial to and slideably engaged within the second tubular structure. The third tubular structure is configured to provide sufficient rigidity to push the mechanical closure device from the distal end of the second tubular structure, and provide sufficient flexibility to assume a curvilinear shape when deflected by the second tubular structure.

Described is a surgical instrument and method for treating female urinary stress incontinence. The instrument includes a first curved needle-like element defining in part a curved shaft having a distal end and a proximal, a tape, or mesh, for implanting into the lower abdomen of a female to provide support to the urethra; a second curved needle element having a proximal end and a distal end, and a coupler for simultaneous attachment to the distal end of the first needle and the distal end of the second needle. In an alternate embodiment, the second curved needle is an anesthesia needle and the method includes anesthetizing the needle pathway through a patient's body to facilitate the passage of the first needle and mesh therethrough.

A urethra support having an elongated mesh tape portion and a mesh extension affixed to the tape portion transverse thereto. In accordance with a method of the invention, the urethra support is inserted into the lower pelvic cavity of a patient with the tape portion forming a sling extending beneath and supporting the urethra of the patient. In this position, the tape portion is generally perpendicular to the urethra. The extension is inserted into the peri-urethral fascia along at least a portion of the length of the urethra. This induces the formation of scar tissue proximate the extension, with the scar tissue eventually contracting thereby compressing the urethra.

A method for repairing friable tissue having a defect therein includes providing a looped barbed suture having a plurality of barbs extending outwardly therefrom along at least a portion of a length thereof, and having first and second ends, first and second end portions and a middle portion therebetween. The first and second ends are fixedly coupled to a single needle, and the plurality of barbs extends outwardly away from the needle. The steps further include placing the looped barbed suture around an outer surface of the friable tissue in a spaced apart configuration and so as to extend across the defect, passing the needle through the friable tissue and around the middle portion of the looped barbed suture one or more times at the middle portion, and removing the needle from the looped barbed suture.
