  • Patent number: 8337414
    Abstract: The present invention is directed to tissue removal devices and methods. A tubular element having an open distal end is advanced into tissue so that tissue enters the tubular element. The tissue, which entered the tubular element is cut to separate the tissue from the surrounding tissue. The tissue is then transported proximally by the cutting element or a separate transport element.

  • Patent number: 8337514
    Abstract: Tissue fasteners carried on a tissue piercing deployment wire fasten tissue layers of a mammalian body together include a first member, a second member, and a connecting member extending between the first and second members. One of the first and second members has a configuration alterable by a deployment wire to permit release of the fastener from the deployment wire after deployment and without causing excessive tissue trauma.

  • Patent number: 8337523
    Abstract: A tissue fastener assembly delivers a fastener for deployment. The assembly includes a fastener including a first member, a second member, the first and second members having first and second ends, and a flexible connecting member fixed to each of the first and second members intermediate the first and second ends and extending between the first and second members. The first member has a longitudinal axis and a through channel along the axis. The assembly further includes a deployment wire slidingly received within the through channel of the first member that pierces into the tissue and guides the first member through the tissue, a guide structure defining a lumen that receives the fastener and deployment wire and guides the deployment wire and fastener to the tissue, and a fastener configuration structure that orientates the second member in a predetermined position relative to the first member within the lumen for dependable deployment.

  • Patent number: 8161587
    Abstract: A therapy mat table has an upper surface and removable mat. A portion of the mat and a separate plate is rotatably mounted within the flat top so as to be capable of being selectively raised and lowered to form a seat back for a patient reclining or sitting on the pad on an elongated side edge of the table. The table may also include transfer bars which help to move a patient on and off the table or when moving to a standing position or while simply standing. The table may further include a stowable foot stop, which prevents backward movement of the patient's feet when the patient is standing between the transfer bars. The table may also include a knee blocker, which helps to limit or prevent buckling of the patient's knees when the patient is standing between the transfer bars.

  • Patent number: 8066727
    Abstract: A method of cutting breast tissue for removal may include a step of providing a tissue cutting device having an elongate cutting element, the cutting element being movable between a bowed position and a retracted position, the cutting element having a radially outer side and a radially inner side. The tissue cutting device may be introduced into a breast and the elongate cutting element may be moved to the bowed position. A power source may be coupled to the elongate cutting element; and the cutting element may be rotated after the moving step so that the cutting element cuts the breast tissue. The radially outer side of the cutting element may have a larger surface area for transmitting energy to cut the tissue than the radially inner side.

  • Patent number: 7942887
    Abstract: The invention provides a device, assembly, and method for transoral endoscopic restoration of a gastroesophageal flap valve. The invention also provides a self-steering and self-closing tissue fixation device for tissue fixation, and an invaginator device for gripping and maneuvering tissue. The restoration device includes a longitudinal member arranged for transoral placement into a stomach, a tissue shaper carried on the longitudinal member that causes stomach tissue to assume a shape related to a gastroesophageal flap, and a tissue fixation device that maintains the shaped stomach tissue in a shape approximating a gastroesophageal flap. The tissue shaper may include a mold. The device may include the invaginator device for gripping and maneuvering esophageal tissue to aid restoration of the gastroesophageal flap, and may include the tissue fixation device.

  • Patent number: 7513867
    Abstract: An element is expanded in the left ventricle to isolate part of the left ventricle. The element has a generally convex outer surface and an apex which together define a desired geometry of the left ventricle. The isolated part of the wall of the left ventricle may be left so that the wall naturally forms around the element or the isolated portion of the ventricle may be evacuated and/or filled. The element may also be used to isolate part of the left ventricle containing a ventricular septal defect or other perforation or opening in the ventricular wall.
