    摘要： A translumenal access device may comprise a cannula defining a first lumen and a hollow needle. The hollow needle may be positioned within the cannula. The hollow needle may comprise a first portion including a sharpened rigid distal portion with a first column strength. The hollow needle also may comprise a second portion including a floppy portion with a second column strength. The second portion may be disposed just proximal to the first portion. The first column strength may be greater than the second column strength. The first column strength may be sufficient to penetrate tissue. The second column strength may allow the second portion to buckle to prevent the hollow needle from further penetrating tissue.

    摘要： An overtube for use with an endoscopic surgical instrument. In various embodiments, the overtube may comprise a substantially flexible helically wound continuous member forming a series of helical coils that define a hollow passage sized to receive a portion of the endoscopic surgical instrument therethrough. The coils may be configured to selectively interlock with each other to stiffen the overtube. An actuation system may be employed to steer the overtube and selectively stiffen it. Some embodiments include a second substantially flexible helically wound member that may be selectively wound between the first substantially flexible helically wound member or segments thereof.

    摘要： A suture tag retrieval device and method for its use are described. The retrieval device has an elongate member dimensioned in cross-section to allow passage thereof through a channel leading to an internal site in a patient, such as, for example, the working channel of an endoscope. The retrieval device has a distal end and a proximal end and defines a passageway between the distal and the proximal ends for passage of a suture. The distal end of the elongate member has a suture engagement portion and a suture tag receiving portion, which may be in the form of a cradle configured to inhibit contact between the suture tag and the channel. To facilitate use with an endoscope, the elongate member is preferably a hollow, flexible tube like device.

    摘要： Several medical drive systems each include a drive system assembly adapted to engage and move at least a portion of a medical apparatus. The medical drive system assemblies each are variously described in expressions such as an assembly adapted to engagingly slide onto a catheter, an assembly adapted to surroundingly attach to a catheter, an assembly adapted to engagingly slide onto a working channel entrance of an endoscope wherein the medical apparatus is insertable into the working channel entrance, an assembly including a spur gear and a nut gear wherein the nut gear includes external teeth engaged by the spur gear, an assembly insertable into a working channel of a flexible insertion tube of an endoscope, and/or an assembly including a drive shaft and a nut gear fixedly attached thereto wherein the drive shaft has at least a hollow portion and the medical apparatus is positionable in the hollow portion.
