Abstract
A method cinches a suture. The method provides a cinch having a suture capturing portion configured to capture a suture, a cinch lock coupled with the suture capturing portion, and a cinch anchor having a lumen. The suture capturing portion is extended out of the lumen to capture the suture. The suture is captured by the suture capturing portion. The suture capturing portion is retracted into the lumen of the cinch anchor. The suture is cinched between the cinch lock and the cinch anchor.
Core Innovation
A cinch comprises a cinch lock having a suture capturing portion and a cinch anchor having a lumen, and cinches a suture by extending the suture capturing portion out of the lumen, capturing the suture while the suture capturing portion is extended outside of the lumen, and retracting the suture capturing portion into the lumen of the cinch anchor. The suture is cinched between the cinch lock and the cinch anchor, thereby forming a cinch lock engagement with the suture in cooperation with the lumen of the cinch anchor.
The system is implemented in an endoscope environment by providing an endoscope having an insertion tube with at least one working channel and a cinching device that moves a flexible drive wire with a handle. The drive wire moves proximally or distally within the working channel to extend the cinch lock out of a delivery housing so that the cinch lock captures a suture after the drive wire extends the cinch lock. The cinch anchor includes a lumen configured so that an inner diameter of the lumen provides an interference fit with the cinch lock and the suture when the cinch lock enters the lumen with the suture.
A cinching device includes a delivery housing configured to fit within a working channel of an endoscope, and a cinch anchor coupled with the delivery housing with a lumen extending from a proximal end to a distal end. A cinch lock having a suture capturing portion captures a suture when the suture capturing portion is extended outside of the delivery housing, and the cinch lock is configured to provide an interference fit with an inner diameter formed by the lumen when the cinch lock enters the lumen with a captured suture. The suture capturing portion can be flexible, and can be a hook integrated with the cinch lock.
Claims Coverage
The independent claims cover three related inventive features: a cinching method using a cinch lock and cinch anchor, an endoscope-based cinching system with handle-driven flexible drive wire actuation, and a cinching device with a delivery housing and anchor lumen. The claims focus on extend/capture/retract actuation and interference-fit cinching between the cinch lock and the lumen.
Extend, capture, and retract suture capturing portion into lumen for cinching
A cinch lock having a suture capturing portion and a cinch anchor having a lumen, extending the suture capturing portion out of the lumen, capturing the suture while the suture capturing portion is extended outside of the lumen, retracting the suture capturing portion into the lumen of the cinch anchor, and cinching the suture between the cinch lock and the cinch anchor.
Endoscope working-channel cinching system with handle-moved drive wire and lumen interference fit
An endoscope having at least one working channel; a cinching device comprising a handle movably coupled with a flexible drive wire configured to move the drive wire proximally or distally within the working channel; a cinch anchor having a lumen; and a cinch lock having a suture capturing portion configured to capture a suture after the drive wire extends the cinch lock out of a delivery housing, wherein an inner diameter of the lumen is configured to provide an interference fit with the cinch lock and the suture when the cinch lock enters the lumen with the suture.
Delivery housing and cinch lock provide interference fit with anchor lumen when cinch lock enters with captured suture
A delivery housing configured to fit within a working channel of an endoscope; a cinch anchor coupled with the delivery housing with a lumen extending from a proximal end to a distal end; and a cinch lock having a suture capturing portion configured to capture a suture when the suture capturing portion is extended outside of the delivery housing, wherein the cinch lock is configured to provide an interference fit with an inner diameter formed by the lumen when the cinch lock enters the lumen with a captured suture.
The claims center on capturing a suture with a suture capturing portion carried by a cinch lock, then reintroducing the cinch lock so that an interference fit is formed with an inner diameter of the anchor lumen, with endoscope working-channel delivery in the system and device claims.
Stated Advantages
Not explicitly described in patent.
Documented Applications
Endoscopic suturing using an endoscope having a working channel, where a cinching device and cinch anchor/lock capture and cinch a suture.
