    摘要: A trocar system for providing access across a body wall includes a trocar and an anchor provided in the form of a first helix. The anchor is adapted for placement in an operative position wherein the anchor extends at least partially through the body wall. A second helix formed on the trocar is size and configured to engage the first helix of the anchor so that rotation of the trocar relative to the anchor moves the second helix along the first helix. In this manner, the trocar is drawn into the anchor as it moves into the body wall. A proximal force applied to the anchor resists tenting of the abdominal wall. The anchor also holds the layers of the body wall together thereby resisting peritoneal separation.

    摘要: A wound retractor for retracting a surgical incision includes an inner ring, an outer ring and a distensible sleeve coupled to the inner and outer rings. The outer ring includes at least a pair of circular tubes coupled to each other. At least one of the circular tubes includes a lumen and a split that forms open ends. A noncompliant tubular hoop having a split therein is positioned in the lumen. The tubular hoop is oriented with its open ends positioned away from the split of the circular tubes. A core is positioned in the lumen of the tubular hoop. The core has a first end and a second end and is oriented with the ends positioned away from the split in the tubular hoop. The circular tubes may be parallel or may form a helical pattern similar to a Mobius strip.

    摘要: A tamponade trocar includes an elongate balloon having a closed distal end and is adapted to expand from a small diameter to a large diameter. A cannula is positioned at a proximal portion within the balloon lumen. A rigid stylet is removably positioned within the balloon and cannula lumens. A distal end of the stylet supported balloon is inserted into a perforation in a body wall and advanced into a body cavity while the balloon is unexpanded. The balloon is expanded and the cannula is advanced to a distal portion of the balloon lumen and across the body wall. At this stage, the perforation is dilated and in compressive tamponade. The proximal portion of the balloon may be removed and a seal housing may be coupled to the proximal end of the cannula. The distal end of the balloon may be punctured and opened, making the trocar ready for use.

    摘要: The trocar system includes a cannula insertable through a body wall using an obturator having a distal tip. A traction tread disposed interiorly of the obturator inverts at the distal tip and extends proximally along the outer surface of the obturator or cannula. At the distal tip the tread can facilitate parting rather than cutting the tissue. Along the outer surface, the tread can engage the tissue to pull it proximally along the advancing obturator. This produces counter forces which can result in a net proximal force facilitating distention of the abdominal wall and separation of the abdominal wall from internal organs. The traction tread can be axially and/or radially continuous. An associated method of operation includes the steps of contacting the body wall with the traction tread at the distal tip, and engaging the body wall with the traction tread along wall portions facing the outer surface.

    摘要: A catheter includes an introducer and a flow isolator adapted for disposition in a primary conduit to facilitate flow in the primary conduit while inhibiting flow and intersecting secondary conduits. The flow isolator may include a tubular mesh and surrounding balloon structure. Alternatively, a sleeve can be provided with a primary opening and a secondary opening which are sized to inflate the sleeve with the body fluid. Structures for deploying the sleeve between a low-profile state and high-profile state may include expandable fingers, or pneumatic chambers inflatable from an external source. In operation the sleeve can be forced by the body fluid against the intersection with the secondary conduits to achieve isolation. Alternatively, the pneumatic chambers can be inflated to form seals with the primary conduit. A blood filter or snare is contemplated to filter any blood clots which may develop around the flow isolator.

    摘要: A trocar fixation device can comprise a cannula, at least one flap coupled to an exterior surface of the cannula within a central region of the cannula, and an elongate tube rotatably mounted onto the cannula and over the at least one flap. The elongate tube has at least one opening extending between an interior surface and an exterior surface of the elongate tube. In a free, activated state, the flap biases radially outwardly from the cannula. In a constrained, deactivated state, the at least one flap is positioned between the cannula and the elongate tube and maintained substantially parallel to the exterior surface of the cannula. The at least one opening in the elongate tube is sized and positioned such that rotation of the elongate tube in a first direction about the cannula exposes the flap in its entirety through the opening and allows the flap to activate.

    摘要: A surgical access port for insertion into a body cavity can have an elongate tubular body extending along an axis between a proximal end and a distal end, and a tip at the distal end of the tubular body for penetrating through a body wall and into the body cavity. The distal tip moves from a first, penetrating position to a second, retaining position when the body wall has been traversed. The surgical access port may further comprise a seal housing connected to the proximal end of the tubular body, the seal housing having an access port providing an opening into the tubular body to allow passage of surgical instruments. The distal tip may be sharp, pointed or bladed. The distal tip may also be substantially blunt or have a conical surface. The access port may further comprise a retention member for connecting the tubular body and the distal tip.
