Abstract:
Devices and methods for reconnecting or supporting torn, damaged or weak tissue are disclosed. The disclosed embodiments can be used on long slender tissue such as ligaments, tendons, nerves, vessels, intestines, muscles, bones, appendages and any other elongate tissue within the body, of both humans and other animals. The devices can wrap around elongate tissue and is capable of supporting the tissue or keeping two severed ends in close proximity to one another. The devices can be used in addition to or in lieu of sutures. The devices can function similar to a Chinese Finger Trap and are capable of decreasing in diameter upon extension, thus constricting upon the tissue. The multiple coils of the devices can make sufficient surface contact on the ligament or tendon, using friction to keep the device in place, while also allowing access for diffusion of oxygen and nutrients.
Abstract:
An anvil (300) for use in connection with a first member (10) of an anastomotic device (100) in the side wall of an intestine is provided. The anvil (300) comprises a distal head portion (301) and a connecting rod (302) extending proximally from the head portion (301). The distal head portion (301) has a first member retaining means (304), being displaceable laterally and centrally between a first member locking position and a first member releasing position. A tool (400) for use in connection with an anvil (300), according to above, is also provided, and a kit of parts comprising the two. The tool (400) comprises a receiving member (401) for receiving the connecting rod (302) of the anvil (300), and a seat (405) for a second member (20) of the anastomotic device (100), said seat (405) being arranged circumferentially of said receiving member (401), and said receiving member (401) being displaceable in relation to said seat (405).
Abstract:
The invention provides a device for urethral anastomosis, for example, following prostatectomy. The device has a flexible slender shaft including a flexible outer sleeve and a flexible inner sleeve inside a lumen of the outer sleeve. A bladder anchoring system anchors the distal end of the inner sleeve inside a urinary bladder, and a urethral anchoring system anchors the outer sleeve in a urethral stump. A ratchet mechanism allows proximal movement of the inner sleeve inside the outer sleeve while preventing distal movement of the inner sleeve inside the outer sleeve. The device is used to urge the urinary bladder towards the internal termination of the urethra to allow anastomosis of the bladder neck to the urethral stump.

Abstract:
The vascular retractor is a vascular anastomosis aiding device. The small tool is composed of a plastic base with hooked legs made from flexible steel wire extending from it for safely engaging and pulling vessel wall. It produces optimal protection to vessel layers and provides a better exposure of anastomosis site during surgical procedure. It makes anastomosis easier, decreases the possibility of trauma to a patient, enables less experienced surgeons successfully performing vascular anastomosis and saves time.
Abstract:
An anastomosis device (10) in which radiographic band markers (26, 28) are used to determine fluoroscopically whether approximation structures (24) hav been deployed based upon the observed alignment of the radiographic band markers and the approximation structures. The radiographic band markers are positioned proximate a distal end (22) of the anastomosis device wherein a medical professional can fluoroscopically compare a position of crimp hubs (30) on the approximation structures with the radiographic band markers.
Abstract:
A translumenal access system includes a translumenal access catheter, a trocar, and one or more guidewires. The trocar may be introduced through adjacent tissue layers, typically from an endoscope, and the translumenal access catheter introduced through the resulting penetration over the trocar. A balloon on the catheter may be used to dilate the penetration, and an enlarged distal portion of the balloon may be used to draw the tissue layers into apposition. The first stent may be exchanged for the trocar and a second stent may be introduced through a side port on the access catheter. The stents may be then used to introduced catheters or other interventional tools, optionally for delivering one or more stents to the enlarged tissue penetration.

Abstract:
Provided is an absorbable vascular anastomotic system including an insertion tube of which a front end has a plurality of hooks protruding outward and a rear end has ring-shaped protrusions, and an interlocking tube having grooves corresponding to the protrusions of the insertion tube such that two insertion tubes are inserted into the interlocking tube at both ends of the interlocking tube to be fixed. The insertion tube and the interlocking tube are formed of a material which is absorbed into a living body, and when two insertion tubes into which two blood vessels are respectively inserted to be fixed to the hooks are inserted into the interlocking tube at both ends of the interlocking tube, inner walls of both the blood vessels come into contact with each other in the center of the interlocking tube to be anastomosed. Since the absorbable vascular anastomotic system does not require an additional anastomotic device, it is possible to perform the anastomosis even in a narrow space. Further, since the absorbable vascular anastomotic system is completely absorbed into a living body, it is possible to avoid a risk of foreign body reaction. After the absorbable vascular anastomotic system is completely absorbed, the anastomosed vessels recover their own elasticity.
