An improved cutting assembly for use with a surgical instrument is provided and includes a pair of cutting blades pivotally mounted on a yoke and a drive member engageable with the cutting blades to move the cutting blades between an open position substantially spaced apart from each other to a closed position wherein the cutting blades are in close cooperative alignment to cut tissue. One or more biasing members are provided adjacent the cutting blades to prevent the cutting blades from splaying or separating during the cutting of tissue.

A supporting structure for a ligating band dispensing device adapted to be coupled to a distal end of an endoscope comprises a substantially cylindrical outer support surface adapted to receive a plurality of ligating bands thereon, wherein the support surface includes a channel extending therethrough from a distal end to a proximal end. The support surface further includes a plurality of shallow slots and deeper slots disposed on the distal end for retaining a trigger string. The shallow slots and deeper slots may be arranged in an alternating fashion, and each of the slots may be narrower than the trigger string to prevent the trigger string from prematurely exiting the slots. The support surface may also include a plurality of axially extending ridges to assist in deployment of the ligating bands by preventing the bands from sliding along the trigger line and facilitating rolling of the bands along the support surface.

An improved distal end for a ligating band dispenser having a transverse groove or ridge profile that promotes rolling of the bands. In one embodiment, the ligating bands and the transverse grooves or ridges are dimensioned such that the width of the bands when stretched on the support surface is substantially the same as the pitch of the transverse grooves or ridges. In another embodiment, the ligating bands and the transverse grooves or ridges are dimensioned such that the width of the bands when stretched on the support surface is less than the pitch of the transverse grooves or ridges. Having the width of the bands when stretched on the support surface be substantially the same as or less than the pitch of the transverse grooves or ridges allows the bands to fit within the grooves, which helps insure that the bands are sufficiently held back by the ridge crests to induce a rolling action. In addition, the transverse grooves or ridges may also be dimensioned such that the height of the ridge crests is sufficiently high to insure that the bands are sufficiently held back by the ridge crests to induce a rolling action.

There is disclosed a porous emboli deflector for preventing cerebral emboli while maintaining cerebral blood flow during an endovascular or open surgical procedure. The device prevents the entrance of emboli of a size able to cause stroke (such as greater than 100 microns) from entering either the right or left common carotid arteries, and/or the right or left vertebral arteries by deflecting emboli downstream of these vessels. The device can be placed prior to any manipulation of the heart or aorta allowing maximal protection of the brain during the index procedure. The deflector has a low profile within the aorta which allows sheaths, catheters, or wires used in the index procedure to pass. Also disclosed are methods for insertion and removal of the deflector.

A suture placement device includes a crook-shaped needle having a suture passage through which a suture thread passes; a suture opening in a tip portion of the needle, from which the suture thread exits the needle; and a bend in the needle including an open portion of the suture passage. The bend defines a suture capture zone in which the suture thread is separated from the needle. A shuttle includes a shuttle body and a shuttle hook. The shuttle hook is formed at a distal end of the shaft. The needle and the shuttle extend from the barrel, and the barrel includes a source of the suture thread and a rotating shaft or cable that causes the shuttle to traverse over the needle. A guide groove guides the shuttle over the needle. The shuttle hook engages the suture thread in the suture capture zone and draws the suture thread to the barrel.

A stent/graft catheter delivery handle comprising a housing and a trigger pivotally connected to the housing on one end of the trigger. Squeezing the free end of the trigger towards the handle housing shifts a pawl, which is engaged with grooves on the outer surface of a stent/graft delivery catheter, longitudinally along the length of the catheter. Shifting of the pawl has the effect of retracting the sheath of the catheter relative to the plunger (inner lumen assembly) of the catheter and thus deploying a stent/graft stored in a proximal end of the catheter.

A surgical device for performing surgery generally includes a handle assembly, an elongate member extending from the handle assembly, an articulation mechanism operatively associated with the handle assembly, and an end effector. The elongate member has an articulating section and straight section. The articulating section is configured to articulate with respect to the straight section. The articulation mechanism is operatively associated with the handle assembly and the articulating section such that the articulating section articulates toward a first direction relative to the straight section upon movement of the handle assembly towards the first direction with respect to the straight section. The end effector is operatively coupled to the articulating section of the elongate member and includes first and second jaw members. The surgical device further includes a locking mechanism configured for fixing a relative position of first and second jaw members.

An inlet stream of particulate material is successively split into smaller stream segments. The segments are spread across a conveyor belt in a magnetic or conductivity separator. Inlet and intermediate stages of the splitter include troughs of triangular cross section to concentrate the streams before splitting them. The flow direction is reversed in each stage to facilitate the axial concentration of the material stream.

The present invention regards system and apparatus for selectively and accurately deploying one or more sequentially positioned medical appliances from a portable medical device. The apparatus includes a body having a channel, a string passing through the channel, and a mechanism for moving the string a predetermined first distance to deploy a first of the medical appliances and for moving the string a predetermined second distance to deploy a second of the medical appliances. The medical appliances may be, but are not limited to, ligating bands.
