摘要:
Apparatus and methods enable insertion and tensioned deployment of a secondary material prosthetic device into a body cavity or other tissue of a patient, such as for example hernia repair mesh into the abdominopelvic cavity of a patient through the hernia site. The present invention establishes fixation sites for the prosthetic device and tensions it against the body tissue. It may also be used implant fixation devices within the body tissue so that the prosthetic device is tensioned into firm abutting contact with the body tissue. Instrument deployment and fixation struts may be advanced in retrograde fashion in order to reduce needed deployment volume within the patient's body cavity. The prosthetic device advantageously may be flexibly coupled to the instrument via fixation devices such as sutures, so as to increase orientation flexibility.
摘要:
A fluid dispensing device having a barrel having a lumen for containing a fluid therein and a flexible structure extending from the barrel. A plunger is axially slidable within the lumen to dispense fluid from the barrel, the plunger having a first set of grooves spaced apart a first distance and a second set of grooves spaced apart a second distance. The flexible structure includes a flexible arm extending transversely with respect to the barrel and configured to engage the grooves.
摘要:
An apparatus for treating hemorrhoids including a first member having a proximal portion, a distal portion and a window formed therein to receive tissue. A third member is operably connected to the second member and movable between a first position and a second position, the third member having a clamping surface movable to the second position to provide a clamping force on tissue received through the window. Movement of the second member in a distal direction moves the third member in the distal direction toward the second position, the third member movable in a distal direction until such movement is limited due to contact and compression of tissue within the window, the second member continuing movement in the distal direction after movement of the third member in the distal direction has been limited.
摘要:
A surgical port comprising a body and first and second cannula extending from the body and movable with respect to the body via an instrument inserted through the respective cannula. The cannulas can extend distally from the body and can include one or more seals. A port assembly and first and second instruments manipulatable in a crossed configuration are also disclosed.
摘要:
A method for promoting contraception by placing a contraceptive device within a uterus without blocking fallopian tubes may involve advancing a distal end of a delivery device through a cervix, advancing the contraceptive device comprising an elongate shape memory member out of the distal end of the delivery device and into the uterus, and limiting inferior migration of the contraceptive device within the uterus. Inferior migration may be limited by allowing the contraceptive device to assume a shape, when subjected to pressure that tends to cause a downward migration of the device within the uterus, in which an expandable middle portion of the device is expanded to contact the inner wall of the uterus and thus limit the downward migration of the device.
摘要:
A system for controlling operation of a radiofrequency treatment device to apply radiofrequency energy to tissue to heat tissue to create lesions without ablating the tissue. The system includes a first treatment device having at least one electrode for applying radiofrequency energy to tissue, a controller including a connector to which a first treatment device is coupled for use, and a generator for applying radiofrequency energy to the electrodes. The controller controls application of energy so that the tissue is thermally treated to create lesions but preventing thermal treatment beyond a threshold which would ablate the tissue.
摘要:
A surgical apparatus for cutting and storing sections of body tissue is provided comprising a housing having a handle assembly, an elongated outer tube extending from the handle assembly, and a cutting tube positioned within the outer tube and movable in response to actuation of the handle assembly between a retracted position and a distal position to cut body tissue. The cutting tube has a chamber formed therein for storing the cut tissue sections. An anvil is positioned at a distal end of the outer tube for forcing each cut tissue section proximally into the chamber of the cutting tube as the cutting tube is advanced to cut the body tissue.
摘要:
An apparatus for closing trocar wounds and a method for using such apparatus. The apparatus includes a fastener having three or more legs attached to a base. The fastener is placed over a wound and its legs are embedded in tissue about the wound. In other embodiments a fastener is placed under the wound to engage fascia and skin tissue.
摘要:
A system for controlling a treatment device generates a graphical interface that visually prompts a user in a step-wise fashion to use the treatment device to perform a process of forming a pattern of lesions that extends both circumferentially and axially in different levels in a body region. The graphical interface displays for the user a visual record of the progress of the process from start to finish and guides the user so that so that individual lesions desired within a given level are all formed, and that a given level of lesions is not skipped.
