An assembly of a medical delivery device includes an inner sleeve including a flange at a proximal end. The flange includes one or more through holes. The assembly also includes an outer sleeve movably coupled to the inner sleeve. A distal tip of the outer sleeve includes a plurality of openings for delivering an adhesive to a treatment site. The assembly further includes a cavity formed between the inner sleeve and the outer sleeve and configured to hold the adhesive prior to the delivering. The assembly yet further includes one or more actuators connected to a proximal end of the outer sleeve and extended via the one or more through holes to a handle of the medical delivery device. Actuation of the one or more actuators moves one of the inner sleeve or the outer sleeve relative to the other to cause the delivering of the adhesive.

A surgical instrument is disclosed. The instrument includes a handle portion, a body portion extending distally from the handle portion and defining a first longitudinal axis and an articulating tool assembly defining a second longitudinal axis and having a proximal end. The articulating tool assembly is disposed at a distal end of the body portion and is movable from a first position in which the second longitudinal axis is substantially aligned with the first longitudinal axis to at least a second position in which the second longitudinal axis is disposed at an angle with respect to the first longitudinal axis. The instrument also includes an articulation mechanism configured to articulate the articulating tool assembly, the articulation mechanism including an articulation sensor assembly configured to transmit a sensor signal to a microcontroller which is configured to determine an articulation angle of the articulation assembly.

A suturing device include a handle, an elongate body, an actuator, and a needle holder. The elongate body connects with the handle. The actuator interacts with the elongate body and is operable between a first operating position and a second operating position. The actuator includes a manually operated member including an operator contact surface. The needle holder extends away from a distal end portion or is provided as part of the distal end portion of the elongate body. The needle holder includes a distal end section having a distal-most tip and defining a needle passage and a distal opening adjacent the distal-most tip. The needle passage is configured to receive at least a portion of an associated needle when the actuator is in the first operating position. The needle holder and the elongate body are rotatable with respect to the handle about a rotational axis.

A method for forming a surgical snare, the method comprising: providing a plurality of filaments; braiding the plurality of filaments together so as to form a braided tubular construct comprising: a proximal tube having an open proximal end, an open distal end, and a proximal tube lumen extending there between; a distal tube having an open proximal end, an open distal end, and a distal tube lumen extending there between; and a loop region disposed between the distal end of the proximal tube and the proximal end of the distal tube, the loop region comprising at least one loop structure, the at least one loop structure comprising at least three of the plurality of filaments braided together; inserting the distal end of the distal tube into the open distal end of the proximal tube and into the proximal tube lumen such that (i) the distal tube is disposed in the proximal tube lumen such that the at least one loop structure extends distally of the distal end of the proximal tube in the form of at least one loop, and (ii) the distal tube lumen extends from a point located distal to the proximal end of the proximal tube to the at least one loop.

In a first aspect of the subject invention, an iris expander is provided which includes a non-metallic, unitary, multi-segmented body which is expandable from a first state to a second state. The second state defines a larger footprint than the first state with the body being defined by a plurality of segments connected by living hinges. In a further aspect, an iris expander is provided which includes a multi-segmented body that is expandable from a first state to a larger-footprint second state. At least one aperture is formed in the body with a channel extending therefrom embedded in the body such that no portion thereof is exposed externally of the body. The channel is formed to accommodate a portion of an instrument for causing adjustment of the body with avoidance of direct contact of the instrument with the tissue of the ins.

An ultrasonic surgical tool system with a tip capable of simultaneously vibrating in plural modes. The system includes a console capable of supplying a drive signal to the tip that includes plural components. Each component has a frequency characteristic that is based in part on the equivalent of current through the mechanical components of the tip. The frequency components are different from each other. Based on the application of drive signal the tip undergoes non-linear vibrations.

A surgical guide includes a base and a drill guide coupled to the base. The drill guide includes a drill guide body defining a drill bore for receiving a drill bit and extending through the drill guide, the drill guide being configured to translate relative the base to adjust a drill guide angle defined by the drill bore and the base, the drill guide further being configured to transition between a locked state and an unlocked state, wherein the drill guide angle is fixed in the locked state and the drill guide angle is adjustable in the unlocked state.

The technical solutions described herein are systems and methods for adjustable surgical guides, virtual planning, and surgical navigation. The system can process preoperative image data of a glenoid, generate a virtual representation of the glenoid face, and maintain a virtual model of a surgical guide. The system can present the virtual representation and the surgical guide in a user interface, determine version and inclination angles for the surgical guide, and adjust the surgical guide's position or orientation. The system can assess virtual plan data, communicate the data to a surgical system, translate the data into movement commands, and execute the movement commands for drilling. The system can access an intraoperative image of the glenoid face, identify the position of a drilling instrument, generate an image to determine the spatial relationship between the instrument and the virtual representation, and present a dynamic visual indicator to guide drilling.
