A cannulation device is disclosed, having a fixed blade, a retractable wedge, and an adjustment nut for mating with a cannula or a cannula assembly. Another cannulation device is disclosed, having a tube with proximal and distal ends. The fixed blade, coupled to the distal end of the tube, comprises a transition edge configured to cover a lead edge of a cannula. The cannulation device has a control rod movable within the tube; a retractable wedge; an actuator coupled to the control rod; and is configured to move the retractable wedge from a piercing position, where the retractable wedge is aligned with the fixed blade, to a retracted position where the retractable wedge has been retracted within the tube. The cannulation device has a cannula adapter and an adjustment nut movable to change a distance between the adjustment nut and the fixed blade.

A surgical assembly is disclosed. The assembly has a cannula. The cannula has an oblong opening on a proximal end, one or more textured features on an outside, and a stabilizer at the proximal end. The assembly also has an obturator sized to fit within the cannula from the proximal end of the cannula. The obturator has a tapered end configured to extend from the distal end of the cannula and a protrusion on a proximal end of the obturator configured to engage a portion of the cannula.

An apparatus for gastric bypass is disclosed. The apparatus for gastric bypass includes a primary passage having an input and an output. The apparatus also includes a bypass conduit, coupled to the primary passage, having an input and an output, wherein the passage input is interspersed with the conduit input. The apparatus further has a primary regulator coupled to the primary passage and adjustable to control a primary flow profile from the input to the output of the primary passage. The apparatus also has a bypass regulator coupled to the bypass conduit and adjustable to control a bypass flow profile from the input to the output of the bypass conduit.

A minimally invasive surgical suturing device has a shaft; a needle slideably coupled to the shaft and having a ferrule engaging end; and a guide tip having a ferrule receiving aperture and moveably coupled to the shaft for selectable movement between a retracted position and an enabled position. In a related method, a distal shaft end, having a guide tip in a retracted position, is passed through a minimally invasive entry point and into a body cavity. The guide tip having a ferrule receiving aperture is actuated into an enabled position such that an insertion profile of the guide tip and shaft in the enabled position is larger than an access dimension of the minimally invasive entry point. A needle, slideably coupled to the shaft and having a ferrule engaging end, is advanced on a path substantially parallel to the shaft, toward and in alignment with the ferrule receiving aperture.

A surgical snare assembly is disclosed. The surgical snare assembly has a suture fastener having an entrance and an exit. The surgical snare assembly also has first and second suture engaging loops. The surgical snare assembly further has first and second handles configured such that: a) movement of the first handle a first distance away from the suture fastener causes the first suture engaging loop to move through the suture fastener from the exit to the entrance; and b) movement of the second handle a second distance away from the suture fastener causes the second suture engaging loop to move through the suture fastener from the entrance to the exit.


A ferrule is disclosed for use with a surgical suturing device. The ferrule has a suture interface and a needle receptacle. The ferrule also has one or more indentations protruding into the needle receptacle. The ferrule further has one or more slits adjacent the one or more indentations. Another ferrule is disclosed for use with a surgical suturing device. The ferrule has a suture interface and a needle receptacle. The ferrule also has three indentations protruding into the needle receptacle. The ferrule further has three slits, each of the slits substantially centered between a different pair of indentations from the three indentations, and wherein each of the slits is longer and thinner than any one of the three indentations.


A self-articulating joint is disclosed for a minimally invasive surgical apparatus. The self-articulating joint has a first elbow component pivotably coupled to a second elbow component, wherein the first and second elbow components are biased to form a non-linear angle relative to each other. The self-articulating joint also has an elbow latch configured to releasably hold the first and second elbow components at a substantially fixed non-linear operating angle.

A surgical device has first and second clamp jaws, at least one of which is pivotable relative to the other. The surgical device also has first and second locking suture guides configured to receive at least one locking suture for knotting to hold the first and second clamp jaws in a clamped position.


A surgical suturing device has a guide tip defining cuff receiving and tissue bite areas. The guide tip has at least one needle guide configured to guide at least one needle through the cuff receiving area and the tissue bite area. Another surgical suturing device has a guide tip defining cuff receiving and tissue bite areas. The guide tip has at least one pair of needle guides configured to guide both the needles of at least one pair of needles through the cuff receiving area and the tissue bite area. The guide tip also has at least one pair of ferrule receiving apertures. The cuff receiving area and the tissue bite area are oriented to avoid cross-over of a suture passed by the at least one pair of needles through tissue in the tissue bite area and a replacement anatomical device sewing cuff in the cuff receiving area.
