A suturing device comprising an elongated member including a cavity formed in a surface thereof, a needle passage, and a vacuum port. When the elongated member is inserted into a body including tissue and a vacuum is applied to the cavity, the tissue is captured by the cavity. A needle pusher is operable to move a needle having a sutured attached thereto through the tissue until a first end of the needle is captured by a needle capturing assembly. A clamp coupled to the elongated member is used to extract the needle from the needle capturing assembly and reposition the needle with suture attached to be re-engaged by the needle pusher. The cavity may include a plurality of cavity portions for capturing multiple contiguous portions of the tissue such that a single pass of the needle and the suture results in the suturing of the multiple portions of the tissue.

A magazine (200;400) for dispensing at least one band (106) onto the tip of a haemorrhoid ligator (100), the magazine (200; 400) comprising at least one expander receiving a respective band, the expander being arranged to expand the band and push it onto the tip (104) of the ligator (100) as the tip (104) is inserted into the magazine (200; 400). The only action required by the medical practitioner to load the band (106) onto the ligator (100) from the magazine (200;400) is to push the tip (104) of the ligator (100) inside the magazine (200; 400) whereupon the band (106) is expanded, pushed into place and is ready for immediate discharge. Therefore the magazine (200; 400) provides a medical practitioner with an easy way to load a haemorrhoid ligator (100).

A medical device that includes a clamp having a body defining a channel and a fixation member that is configured to move relative to the body from an unlocked position to a locked position. The medical device includes an actuator coupled to the fixation member and configured to move the fixation member from the unlocked position to the locked position. The fixation member extends at least partially into or radially outward from the channel in response to moving from the unlocked position to the locked position.

Disclosed embodiments include apparatuses, systems, and methods for facilitating surgical anastomosis between bodily passages. In an illustrative embodiment, an eversion mechanism is configured to partially evert a distal portion of an opening of a receiving passage and further configured to leave a proximal portion of the opening of the receiving passage in a non-everted position. A donor support mechanism is configured to partially evert a distal portion of an opening at an end of a donor passage and further configured to leave a first proximal portion of the end of the donor passage in a non-everted position. The donor support mechanism is further configured to form a passage juncture at the end of the donor passage and the opening of the receiving passage. A suturing mechanism is configured to motivate a filament through a generally helical path around the passage juncture to suture the donor passage to the receiving passage.

The present application discloses surgical auxiliary equipment for sutureless closed skin incisions in the deep fascia of limbs, comprising subcutaneous negative pressure drainage device, incision closing device, negative pressure device above skin and a plurality of drainage needles, and used for draining the effusions in subcutaneous soft tissues through a plurality of drainage needles. Meanwhile, edge of the skins are squeezed by the incision closing device, and the inner cavity of the subcutaneous incision is forced to be maintained in a closed state during healing and rehabilitation process under the pressure of a negative pressure drainage device, the subcutaneous negative pressure drainage device delivers liquid drug to the inner cavity of the subcutaneous incision while draining effusions in the inner cavity of the subcutaneous incision, to ensure that the environment in the inner cavity of the subcutaneous incision is maintained in a state that facilitates the recovery of the incision.

A method using a guide to assist in insertion of a helicoidal member in a target biological tissue. The method includes abutting a substantially longitudinally extending portion of the guide against a target tissue exposed surface with the helicoidal member mounted thereto so that at least a portion of the guide is inserted in a helicoidal member passageway substantially parallel to a helicoidal member longitudinal axis of the helicoidal member; adhering the substantially longitudinally extending portion of the guide to the target tissue exposed surface with the helicoidal member longitudinal axis substantially parallel to the target tissue exposed surface; and advancing the helicoidal member in the target biological tissue in a substantially helicoidal movement with the guide remaining substantially fixed relative to the target biological tissue.

Tissue ligation devices and methods are provides to mechanically strangulate abnormal or undesirable tissue. Tissue ligation devices include a catheter having an outer diameter smaller than the inner diameter of a standard endoscope channel such that the catheter can be inserted into the endoscope. Tissue ligation devices also include a ligation system with an expandable hood disposed located at the distal end of the catheter. A suture extends through a lumen of the catheter and has a distal loop portion exposed outside of the expandable hood.

A collapsible, clamping and/or steerable apparatus in conjunction with negative pressure system and methods for using such an apparatus are described. Preferred embodiments of the invention have lengths and bent and/or increase their curvatures along their lengths, by preferentially contracting and transforming upon negative pressure.

A gastric tube for use in a bariatric surgical procedure includes an elongate tube and a movable component supported on an outer surface of the elongate tube. The elongate tube has a non-circular cross section along at least a portion of a length of the elongate tube. The movable component is movable between an unexpanded configuration and an expanded configuration. In the unexpanded configuration, the movable component is disposed in abutting engagement with the outer surface of the elongate tube. In the expanded configuration, the movable component bows outwardly from the outer surface of the elongate tube.

A surgical access device includes a housing having a tubular member extending therefrom. The tubular member has inner and outer walls defining an annular lumen therebetween. A passageway extends between proximal and distal openings of the tubular member. The passageway is configured to receive a surgical instrument therethrough. A conduit is disposed in the annular lumen and includes spiral segments where each spiral segment is engaged with an adjacent spiral segment. The conduit is flexible in a first state and is fixed in a second state. A valve assembly is coupled to the housing and includes a port that is in fluid communication with the annular lumen. The port is attachable to a source of fluid.
