An implantable prosthesis designed to transition from a contracted state to an expanded state, including a continuous tubular helical winding and a plurality of bridges. The helical winding includes a plurality of circumferential sections spaced apart along a helical axis, each of the plurality of circumferential sections forming a non-orthogonal helical angle relative to the helical axis. The plurality of bridges connect adjacent circumferential sections, each having a length extending from a first end to a second end on a plane orthogonal to the helical axis, the length being equal to a circumferential offset between the adjacent circumferential sections in both the contracted state and the expanded state. The implantable prosthesis also includes a first annular ring orthogonal to the helical axis, and a first marker having a first end connected to the first annular ring, and a second end coupled to the first end of the helical winding.

Highly flexible stent and method of manufacture

A stent that has a reduced state, an expanded state, and a delivery state, includes helical windings, a bridge, and a sacrificial bridge. The helical windings define a cylinder with a helical axis including a strut having a straight portion connected to a curved portion, wherein the straight portion aligns with the helical axis. The bridge connects adjacent windings. The sacrificial bridge connects adjacent windings and is configured for removal in the expanded state.

Stent and method for manufacturing the stent

An endoscopic includes a handle, a tubular member, a control member, and an end effector assembly. The handle has a stationary member and a movable member. The movable member includes a constrained curved path for passage of the control member. The tubular member has an end coupled to the stationary member and a distal end rotatably coupled to the end effector assembly. The control member extends through the curved path, the tubular member, and is coupled to the end effector assembly. A knob is attached to the movable member and control member. Displacement of the movable member relative to the stationary member causes actuation of the end effector assembly, and rotation of the knob on the movable member causes the control member to rotate within both the constrained curved path and the tubular member, and results in rotation of the end effector assembly.

Rotatable endoscopic instrument

Preferred embodiments of a stent with a high degree of flexibility are shown and described. The stent can include a continuous helical winding having interconnected struts joined at vertices, and having bridges connecting sections of the helical winding to each other. An annular ring can be provided at one or both ends of the helical winding, and the annular ring can have extensions extending to connect to the helical winding. One of the extensions can connect to a bridge and another extension can connect to a vertex. The struts at the ends of the helical winding can have strut lengths that differ from the strut lengths of the struts in a central portion of the winding between the ends of the winding.

Preferred embodiments of a stent with a high degree of flexibility are shown and described. The stent can include a continuous helical winding and at least one bridge. The continuous helical winding has a plurality of circumferential sections that circumscribe a longitudinal axis from a first end to a second end to define a tube. The circumferential sections are spaced apart along the axis. The at least one bridge is configured to connect one circumferential section to an axially-spaced adjacent circumferential section. The at least one bridge extends on a plane generally orthogonal with respect to the axis.

A stent includes a series of helical windings defining an outer circumference of a cylinder. The helical windings include a plurality of struts having straight portions connected by curved portions. The straight portions may be substantially aligned with a longitudinal axis of the stent when the stent is in a reduced state. A plurality of bridges connect adjacent windings. The bridges may be substantially orthogonal to the longitudinal axis of the stent in the reduced state. A plurality of radiopaque members extend from a terminal helical winding. The radiopaque members include an extension portion and an end portion. The extension portion may have a first width and the end portion may have a second width greater than the first width. The end portion may include an extreme end substantially orthogonal to the longitudinal axis of the stent.

An endoscopic instrument includes a control wire having a push rod at its distal end and an end effector assembly having first and second effector elements such as scissors blades mounted on a clevis. The effector elements are operated by a cam-pin on the push rod riding in cam-slots defined in the effector elements. According to one aspect of the invention, the effector elements are symmetrically opened even when the push rod is canted relative to the clevis. According to another aspect of the invention, the effector elements can be rotated into a closed configuration that minimizes the distal dimension across the effector elements. In addition, the effector elements, when in the closed configuration, can rotate together to facilitate insertion of the end effector into an entry portion of an endoscope.

Endoscopic instrument

An endoscopic instrument includes an elongate hollow member, an actuator that moves axially through the hollow member, and first and second end effectors with respective tissue engaging edges. At least one of the end effectors is rotatably coupled to the hollow member adjacent its distal end. At least one of the end effectors includes a base supporting a resilient leaf-spring portion that includes a respective cutting edge. The resilient leaf-spring portion extends from the base in a cantilevered arrangement and generates a spring force acting on the respective cutting edge such that in a loaded state there is an automatic preload force imparted between the cutting edges of the end effectors to maintain a consistent and continuous mating force between the two opposed tissue engaging edges preferably over the complete range of rotational movement of the end effectors.

Surgical instrument with end effector assembly

An endoscopic instrument includes an end effector assembly having first and second scissors blades mounted on the clevis. Laterally offset from the cutting edges a tissue stop is provided on each tissue receiving surface to hold and/or put traction on tissue. The tissue stop may include tenaculum or saw-like projections.

Endoscopic scissors instrument with friction enhancing tissue stops

An endoscopic scissor instrument includes an elongate hollow member, an actuator that moves axially through the hollow member, and first and second scissor blades with respective cutting surfaces. At least one of the scissor blades is rotatably coupled to the hollow member adjacent its distal end. At least one of the scissor blades includes a base supporting a resilient leaf-spring portion that includes a respective cutting edge. The resilient leaf-spring portion extends from the base in a cantilevered arrangement and generates a spring force acting on the respective cutting edge such that in a loaded state there is an automatic preload force imparted between the cutting edges of the scissor blades to maintain a consistent and continuous mating force between the two opposed sharpened cutting edges preferably over the complete range of rotational movement of the scissor blades.

Scissors assembly

An endoscopic instrument includes a tubular member having a proximal end and a distal end, a clevis at the distal end of the tubular member, and an end effector assembly mounted on the clevis. A control member extends through the tubular member and includes a cam-pin coupled to the distal end thereof. The end effectors are controlled with a cam-pin and cam-slot arrangement, with the end effectors including the cam-slot and such cam-slot having a proximal end slot bilaterally widened to permit the cam-pin additional movement therein. When the cam-pin is retracted to move the end effectors into a closed positions and then further retracted into the bilaterally widened area, the end effectors can rotate together in the same direction to facilitate movement through a rigid bend in an endoscope.

Endoscopic instrument with bi-laterally widened cam-slot at end effector

A tapered helical implantation device for peripheral arteries and other body lumina of locally varying diameter, including struts connected by loops and shaped in a helical winding. The helical winding defines turns and, when expanded, has a first end with a first expanded circumference and a second end with a second expanded circumference greater than the first expanded circumference to form a stent tapering outward from the first end towards the second end. Bridges connect adjacent ones of the turns. The struts, the loops, and the bridges define a series of pores aligned along the helix, the pores having a substantially uniform pore size. The pores has a substantially similar area. The pore size limits a size of a particle that can pass therethrough. In particular, the pore size limits a size of a spherical particle that can pass therethrough.
