A surgical suturing device including a needle assembly having a needle housing and a needle with an elongated rod that slides inside of the needle housing and has a notch at its proximal end. The handle assembly includes a longitudinal handle housing sized and configured to releasably receive the needle assembly, a thumb slide assembly movable longitudinally on the handle housing, a needle latch connected to the thumb slide assembly and having a releasable latching relationship with the notch of the needle rod, a locking lever pivotally connected to the handle housing that releasably engages a depression on an exterior of the needle housing, and a locking lever latch makes contact with the locking lever and holds it the locking position.

Expandable needle suture apparatus and associated handle assembly with rotational suture manipulation system

A surgical suturing device having an axis extending between a proximal end and a distal end is operable to move a suture through body tissue. An actuating rod extends between the handle assembly and the shaft. A needle assembly at the distal end of the actuating rod is movable with the actuating rod between an extended state and a retracted state. Bifurcated portions of the needle assembly define a suture slot, the bifurcated portions have a proximate relationship when the needle assembly is in the retracted state and having a separated relationship when the needle assembly is in the extended state. The needle assembly is biased to the retracted state and the bifurcated portions are biased to the separated relationship. A handle assembly is configured to releasably receive the needle assembly and is operable to move the needle assembly between a free suture state and a captured suture state.

Expandable needle suture apparatus and associated handle assembly

A surgical suturing device () having an axis extending between a proximal end and a distal end is operable to move a suture () through body tissue (). A handle assembly () is coupled to an elongated shaft () having a hollow configuration. An actuating rod () is disposed to extend between the handle assembly () and the shaft (). A thumb actuation assembly is coupled to a proximal end of the actuating rod () for moving the rod both axially and rotationally. A needle assembly () at the distal end of the actuating rod () is movable with the actuating rod () between an extended state and a retracted state and at various angular orientations.

A medical device () includes an articulating shaft (, or) with a pair of slat assemblies (). By moving an articulator (), the slat assemblies () are configured to concurrently push while the other pulls in order to bend the articulating shaft (). The articulating shaft () includes a series of pivot members (and, orand). The pivot members () may include inner links () and outer links (). A method for articulating a shaft of a medical device is also provided.

Medical device with articulating shaft

A surgical suturing device () having an axis extending between a proximal end and a distal end is operable to move a suture () through body tissue (). A handle assembly () is coupled to an elongated shaft () having a hollow configuration. An actuating rod () is disposed to extend between the handle assembly () and the shaft (). A thumb actuation assembly is coupled to a proximal end of the actuating rod () for moving the rod both axially and rotationally. A needle assembly () at the distal end of the actuating rod () is movable with the actuating rod () between an extended state and a retracted state and at various angular orientations. Bifurcated portions () of the needle assembly () define a suture slot (), the bifurcated portions having a proximate relationship when the needle assembly () is in the retracted state and having a separated relationship when the needle assembly () is in the extended state. The needle assembly () is biased to the retracted state and the bifurcated portions () are biased to the separated relationship. A handle assembly () is operable to move the needle assembly () between a free suture state and a captured suture state. In an associated method of use, the needle is bifurcated to form at least one pair of arms (or) to define a suture slot ().

A suture anchor (e.g.) for knotlessly securing nearby tissue to bone is formed from an anchor body (e.g.) that includes a mechanism for being securely anchored to the bone, an elongated suture puller (e.g.) extending through the anchor body with a proximal end for being pulled in a proximal direction by a surgeon and a distal end (e.g.) with a suitable mechanism for engaging suture (e.g.), suture (e.g.) carried by the engaging mechanism (e.g.) at the distal end (e.g.) of the elongated suture puller (e.g.), and a suture locking mechanism (e.g.) that substantially prevents the suture (e.g.) from moving in at least a first direction after being pulled into and through the anchor body (e.g.) by the elongated suture puller (e.g.).

A surgical suturing device having an axis extending between a proximal end and a distal end is operable to move a suture through body tissue. A handle assembly is coupled to an elongated shaft having a hollow configuration. An actuating rod is disposed to extend between the handle assembly and the shaft. A needle assembly at the distal end of the actuating rod is movable with the actuating rod between an extended state and a retracted state. Bifurcated portions of the needle assembly define a suture slot, the bifurcated portions have a proximate relationship when the needle assembly is in the retracted state and having a separated relationship when the needle assembly is in the extended state. The needle assembly is biased to the retracted state and the bifurcated portions are biased to the separated relationship.

A tool for inserting a bone fixation device is provided. The tool generally includes an elongate outer body and an elongate inner body, each having a proximal end, a distal end, and a longitudinal axis. The tool typically includes a pin-receiving portion at the distal end of the outer body for receiving a proximal pin of a bone fixation device. The tool may further include first and second levers pivotally mounted to the inner member at respective pivot axes, and each of the levers having a gripping portion. The levers preferably include finger engagement portions, wire-gripping portions, and are preferably configured to be axially movable relative to the outer body. The levers are generally configured such that a proximal force on the finger engagement portions relative to the outer body will cause the pin engagement portions to close and to move proximally such that a guidewire of a bone fixation device placed between the wire-gripping portions may be gripped and pulled proximally.

A medical device includes an articulating shaft with a pair of slat assemblies. By moving an articulator, the slat assemblies are configured to concurrently push while the other pulls in order to bend the articulating shaft. The articulating shaft includes a series of alternating pins and pivot members. Each pin defines an aperture that collectively forms a passageway for receiving an actuator or a tube. The pair of slat assemblies extend generally parallel to each other on opposite sides of the pins. A method for articulating a shaft of a medical device is also provided.

The invention relates to a deployment systems for deploying a bone fixation device. One embodiment of a deployment system includes a syringe-shaped body configured to provide proximal traction to a bone fixation device in response to a compressive force between a finger grip and a plunger adapted to be engaged by the heel of a clinician's hand. The device may include a collet for gripping a proximal pin of a fixation device. The deployment device may also include a tool that includes an elongate body with a distal tip adapted to rotationally engage a bone fixation device in order to axially rotate the fixation device. A further deployment device embodiment includes a cauterizing tip for heat-cutting an excess portion of a pin of a bone fixation device.
