Abstract: Disclosed embodiments include apparatuses, systems, and methods for driving a needle to facilitate suturing, such as may be performed in a surgical anastomosis procedure. In an illustrative embodiment, an apparatus includes a frame configured to counter-rotatably support two generally parallel rollers. A first roller supported by the frame has a flat surface configured to rollably engage a first face of a shaft of a helically-shaped needle. A second roller supported by the frame has a grooved surface defining a groove that is configured to at least partially receive a second face of the shaft. The bottom of the groove has a bottom width at least as wide as the second face and bounded by sides extending to a groove opening at the grooved surface having a surface width that is wider than the second face.

Abstract: A surgical device comprising: a closure assembly comprising: (a) a movement unit including (i) a bar and (ii) a contact element, wherein the bar, the contact element, or both move in a direction of a prescribed motion; (b) a latch unit comprising: (i) a latch plate including: (1) a hook latch that selectively receives the bar, the latch plate being movable between: (A) a lockable state where the hook latch is engageable by the bar, and (B) an unlockable state where the hook latch is unengageable by the bar; (c) an indicator mechanism that moves into alignment with the prescribed motion of the contact element, the bar, or both when the latch unit is in the unlockable state so that the indicator is contacted by the bar, the contacting element, or both generating an indication.

Abstract: A surgical device comprising: a closure assembly including: (a) a latch unit comprising: (A) a hook latch, having a home position, (B) a forward bias constraint, (C) a rearward bias constraint, and (D) a bias member extending between the forward bias constraint and the rearward bias constraint so that the bias member has a pre-load when the hook latch is in the home position; (b) a movement unit including a bar that is movable relative to the latch unit so that the bar is movable in a prescribed motion into contact with the latch unit to create a locked state; and wherein the bar moves into contact with the hook latch driving the hook latch in a first direction, away relative to the home position, and then the hook latch is moved by the bar in a second direction relative to the home position, and a loading of the bias member is increased from the pre-load when the hook latch is moved in either the first direction away from the home position or the second direction away from the home position.

Abstract: A probe of a target identification system can be extended via a first lumen of a viewing instrument, such as for illuminating an area beyond a distal end of the viewing instrument via an optical path of the viewing instrument. An optical response to the illumination of the area can be received via an optical path of the probe and can be split from other optical signals of the optical path. The optical response information can be used to identify characteristics of a target and to adjust parameters of a working instrument such as a working instrument contemporaneously using the probe.

Abstract: A surgical device that includes a first support member extending along a longitudinal axis; a bladder located on the first support member; a first sealing member located on the bladder; and a second sealing member located on the bladder. The sealing member is located on one side of the longitudinal axis; and the second sealing member is located on another side of the longitudinal axis. The bladder is inflatable, and inflating the bladder changes a position of the first sealing member, the second sealing member, or both relative to the first support member.

Abstract: An electrosurgical medical device that includes a jaw assembly. The jaw assembly includes a first jaw body and a cutting member; and a second jaw body. During a first use state, the medical device is configured to pass a therapy current supplied by a power source between the first jaw body and the second jaw body to electrosurgically effect an anatomical feature. During a second use state, an anatomical feature is electrosurgically effected by contacting the anatomical feature with a medial edge of the cutting member while a second therapy current from the power source is passed between the cutting member and the first jaw body and/or the second jaw body.

Abstract: Provided is a medical device comprising an inner tubular member, an outer tubular member having a distal end and an open window disposed at the distal end, a first electrode and/or a second electrode disposed at the distal end of the outer tubular member, and a cannulated plunger or armature or shaft configured to drive the inner tubular member to cut tissue in cooperation with the open window of the outer tubular member wherein the first electrode and the second electrode are configured to provide RF energy needed for surgical operation and wherein the first and the second electrodes may be configured to be symmetrical or substantially symmetrical along a longitudinal axis of the outer tubular member or wherein the first electrode is configured to cover the open window of the outer tubular member and extended to one side of the outer tubular member and the second electrode is configured to be disposed on the other side of the outer tubular member. Also provided are methods of making a medical device as described herein.

Abstract: A surgical needle comprising: (a) a sensor; (b) a distal tip with the sensor being located at the distal tip; (c) a needle advancing mechanism that is adjustable to change an insertion depth; and (d) a control unit in communication with the needle advancing mechanism; wherein the sensor provides a signal to the control unit regarding a thickness of a feature of interest and the control unit controls the insertion depth based upon the signal from the sensor so that the insertion depth into the feature of interest is varied or the control unit prevents the needle advancing mechanism from activating.

Abstract: A forceps having a first jaw and a second jaw, where at least one of the first and second jaws is capable of moving between an open position and a closed positions. The forceps including an inner shaft located within an outer shaft and extending along the longitudinal axis, and a drive bar coupled to and extending distally from the inner shaft. The drive bar including a pair of drive bar struts extending from a distal portion of the inner shaft and positioned laterally inward of at least one of first and second set of flanges of the first and second jaws. A drive pin is securable to the pair of drive bar struts and the drive bar is translatable within the outer shaft to translate the drive pin to move the first jaw and/or the second jaw between open and closed positions.

Abstract: Forceps can include a drive pin, an outer tube, a first jaw, a second jaw, and an inner shaft. The outer tube can extend along a longitudinal axis. The first jaw can be pivotably connected to the outer tube. The first jaw can include a first flange that can be located at a proximal portion of the first jaw. The first flange can include a first chamfered edge configured to limit extension of the first flange laterally beyond an outer surface of the outer tube when the first jaw is in a closed position. The inner shaft can be located within the outer tube and can extend along the longitudinal axis.
