摘要:
Methods and devices for illuminating a body cavity or an internal region of a body are disclosed. In one aspect, a percutaneous illumination device for illuminating a body cavity includes an elongate member with an illumination source, and two support members disposed on the elongate member that are adapted to be positioned on opposite sides of a tissue surface for stabilizing the device. Variations on such an illumination device, kits that include such devices, and methods of utilizing such devices are all described within the present application.

A fastener is used during endoscopic procedures in which a suture is used in creating a predefined pouch through tissue apposition within the stomach. The fastener includes a fastener body having a tissue anchor for selectively securing the fastener body to tissue. The fastener body also includes a connection aperture shaped and dimensioned for passage of a suture therethrough.

A surgical suturing apparatus includes a suture housing, a needle mounted within the suture housing for movement about an arcuate path, and a drive assembly operably associated with the needle for controlling movement of the needle with a suture secured thereto about the arcuate path in a manner facilitating application of the suture to tissue. The drive assembly includes a friction camming member that moves along the suture housing under the control of the drive mechanism, wherein actuation of the drive mechanism causes the friction camming member to selectively engage and disengage the needle causing the needle to move about the arcuate path.

A method for inserting an instrument through a natural orifice. The instrument has a low profile orientation and a deployed orientation which is larger than the size of the natural orifice through which it is to be inserted. The method is achieved by coupling the instrument to an endoscope and placing the instrument in its low profile orientation, insetting the endoscope and the instrument through a natural orifice to a target position within a body while the instrument is in its low profile orientation, actuating the instrument to it is deployed orientation, and returning the instrument to its low profile orientation and withdrawing the instrument from the body through the natural orifice.

Methods and devices are provided for attaching one or more ancillary devices to an endoscope. The ancillary device can be any device that is used in conjunction with endoscopic procedures, such as, by way of non-limiting example, an accessory channel, tube, or sleeve, an indwelling tube or feeding tube, and surgical tools such as graspers, snares, etc. The ancillary device(s) can be positioned adjacent to and along side an external surface of an insertion portion of an endoscope for inserting into a body lumen, and one or more attachment devices can be used to mate the ancillary device(s) to the endoscope at one or more attachment locations. In use, the attachment device(s) will allow the ancillary device to move in coordination with the endoscope, thus allowing the endoscope and the ancillary device(s) to be introduced and guided through a tortuous pathway. In certain exemplary embodiments, the attachment device(s) can be configured to prevent radial movement, i.e., twisting, of the ancillary device relative to the endoscope, yet allow axial sliding of the ancillary device relative to the endoscope.
摘要:
A surgical stapler having a selectively bendable end effector is provided. A staple holding jaw of the end effector is coupled to another jaw for grasping tissue to be stapled. The stapler can adapted to drive staples into tissue having a pattern conforming with the selected shape of the end effector. In particular, the end effector can be adapted to drive staples in a linear pattern when the end effector orients staples in a substantially linear configuration. The end effector can also be adapted to drive staples in a non linear pattern when the end effector orients staples in a non linear configuration. Methods of stapling tissue with a stapler having a bendable end effector are also discussed.
摘要:
A gastric reduction apparatus provides for the secure attachment of multiple fasteners into the gastric wall, the fasteners being linked with a flexible member in a manner permitting the reduction of the effective size of an individual's stomach. The apparatus includes an applicator head including a proximal end and a distal end. The applicator head of the gastric reduction apparatus includes a cavity shaped and dimensioned for receiving tissue. A fastener attachment mechanism is positioned within the cavity for access to tissue that is pulled within the cavity and the fastener attachment mechanism includes a plurality of fasteners.
摘要:
An endoscopic apparatus shaped and dimensioned for passage through an orifice in the body includes a scope attachment member coupled to an endoscopic instrument, and a connection member attaching the scope attachment member to the endoscopic instrument. The connection member has an insertion orientation sized for passage through the orifice and a deployed orientation too large to pass though the orifice. When the connection member is in its insertion orientation the endoscopic instrument is positioned closely adjacent an exterior of an endoscope for low profile insertion of the endoscopic instrument through an orifice, and when the connection is in its deployed orientation the endoscopic instrument is spaced from the endoscope to improve visibility.
摘要:
An endoscopic instrument to be used with an endoscope. The instrument includes an elongated tube having a distal end and a proximal end, an end effector attached to the distal end of the elongated tube, and a handle attached to the proximal end. The handle includes a mechanism for attaching the instrument to a first vacuum source. The handle further includes a second vacuum source integral with the handle for amplifying the first vacuum source, whereby the first and second vacuum sources combine to operate the end effector.
