摘要:
Disclosed are methods and apparatus for implantation into the walls of an organ such as the stomach. Deformable or inflatable anchors with a connector between are used to pull the walls of the organ together, or to implant devices in the wall of the organ. Also disclosed are surgical instruments useful in practicing the disclosed methods.
摘要:
Devices, systems and methods for compressing, cutting, incising, reconfiguring, remodeling, attaching, repositioning, supporting, dislocating or altering the composition of tissues or anatomical structures to alter their positional or force relationship to other tissues or anatomical structures. In some applications, the invention may be used to used to improve patency or fluid flow through a body lumen or cavity (e.g., to limit constriction of the urethra by an enlarged prostate gland).
摘要:
A cleat for securing suture to tissue, the cleat comprising an elongated body having a distal end and a proximal end, the distal end having a distal slot extending proximally into the elongated body, and the proximal end having a proximal slot extending distally into the body; the distal slot comprising a wide section and a narrow section, wherein the wide section has a width such that the suture is slidably accommodated therein and the narrow section has a width such that the suture is bound therein, and further wherein the wide section is disposed distally of the narrow section. A method for securing a first object to a second object, the method comprising providing a suture and a plurality of cleats slidably mounted on the suture; passing one end of the suture and a first cleat through the first object and the second object; tensioning the suture so as to secure the suture to the first cleat; passing a subsequent portion of the suture and a second cleat through the first object and the second object; and tensioning the suture so as to secure the suture to the second cleat.
摘要:
Described are methods and apparatus for use in supporting tissue in a patient's body. In some embodiments, the patient's breast or another tissue is supported. One method involves introducing a superior soft tissue anchor into a patient, the anchor having an inferiorly facing total surface area; and introducing at least one inferior soft tissue anchor into the patient, such that the at least one inferior soft tissue anchor is suspended from the superior soft tissue anchor, the sum of all of the at least one inferior soft tissue anchors having a superiorly facing total surface area. The inferiorly facing total surface area of the superior anchor can be greater, such as at least two times greater than the superiorly facing total surface area of the at least one inferior anchor.
摘要:
An apparatus and method for suture fixation. A suture fixation device includes a body having an inner end and an outer end and a pathway. A restriction may be provided in the pathway that relatively freely permits movement of a suture through the pathway in a first direction and inhibits movement of the suture through the pathway in a second direction. A suture provided in a passageway formed in bone may be secured at an opening into the passageway using a suture fixation device that has a portion positioned outside of and adjacent the opening in contact with portions of cortical bone. The suture fixation device may include a flange portion adapted to be positioned outside of and adjacent a suitably sized hole formed in tissue, such as bone. An inner end of the suture fixation device may extend from the flange portion and be positioned in the hole adjacent cancellous bone.

An annuloplasty system for repairing incompetent heart valves is provided. This system includes a substantially circular valve reinforcing device adapted to be surgically implanted into around a heart valve annulus; anchoring means for attaching the substantially circular valve reinforcing device to the heart valve, wherein attaching the substantially circular valve reinforcing device to the heart valve annulus reduces the circumference of the heart valve annulus by plicating annular tissue underneath the valve reinforcing device; and constricting means for, if necessary, reducing the circumference of the substantially circular valve reinforcing device, wherein reducing the circumference of the substantially circular valve reinforcing device further reduces the circumference of the heart valve annulus.
摘要:
Systems, devices and methods for treating internal tissue defects, such as septal defects, are provided. An exemplary method of treating an internal tissue defect, specifically a method of closing a patent foramen ovale (PFO), can include passing a closure element from a right atrium through a septal wall in a first location and into the left atrium. A capture device, which can be configured as a snare-like device, can be used to capture the closure element in the left atrium and pull the closure element back through the septal wall in a different, second location, such that the closure element is routed over the PFO. The closure element can then be anchored and/or locked against the septal wall such that the PFO is at least partially closed.
摘要:
A resorbable suture anchor operable to hold a suture within a bone. The suture anchor has a cannulated tip that receives a driver during implantation of the anchor, the driver extending from the tip when the anchor is seated on the driver. The anchor further has at least one engagement surface to prevent migration of the anchor from the implantation site. The anchor is made of a resorbable material to permit resorbtion of the anchor within a patient at a desired rate.

Disclosed are methods and apparatus for implantation into the walls of an organ such as the stomach. Deformable or inflatable anchors with a connector between are used to pull the walls of the organ together, or to implant devices in the wall of the organ. Also disclosed are surgical instruments useful in practicing the disclosed methods.
