Abstract: A system for a medical device that can operate multiple actuated implements with sophisticated and individual motion profiles using a single user actuator. The system has a handle having a pair of slots for each implement and an actuator positioned in the handle for movement between a first position and a second position that has a groove for each implement. Each implement is coupled to the handle a barrel that is captured in the pair of slots and driven by the groove of the actuator. The shape of the pair of slots and the corresponding groove combine to provide a motion profile for the implement that is independent from any other implement having its own pair of slots and groove. Multiple implements may thus be driven simultaneously and can have complex and coordinated movement based on user operation of the single actuator.

Abstract: Disclosed is a suturing needle having a thread attachment portion and a ramp portion comprising a tapered portion extending from a proximal end of the needle to cover at least a portion of a suture thread swaged in the thread attachment portion. The tapered portion of the ramp portion provides a smooth transition from a diameter of the suture thread to a diameter of the needle body. The tapered transition portion allows for engaging the suture needle on rollers of a rotational needle driver in one smooth motion. The suturing needle includes a hollow flexible extension component having a distal end and a proximal end, the distal end connected to the proximal end of the thread attachment component, and the proximal end attached to the distal end of the tapered extension ramp portion. The suturing needle can include a combination of flexible and non-flexible sections and/or a combination of straight and curved sections.

Abstract: Systems, apparatuses, and methods disclosed herein may be directed to clips for medical implementation, including clips for a portion of a heart. The clips may be configured to close the portion of the heart, to reduce blood flow therethrough as well as passage of clots or other undesired materials. In examples, the clips may be configured to close the left atrial appendage (LAA). The closure of the LAA may reduce the possibility of stroke or other maladies stemming from fluid flow with the LAA. In examples, the clips may be positioned exterior of the LAA, to extend over an outer surface of the LAA for closure.

Abstract: A needle assembly (20, 120, 220, 320) is provided that includes a needle (22) and a suture (24) coupled to the needle (22), and a needle guide tool (30, 130, 230, 330). The needle guide tool (30, 130, 230, 330) is configured to pass the needle (22) and the suture (24) through tissue of a body portion of a subject, and includes a needle guide (34, 134, 334), which is shaped so as to define a needle-guide surface (36, 136) that is configured to slidably contact a body-portion surface of the body portion without penetrating the body¬ portion surface. The needle guide tool (30, 130, 230, 330) also includes a proximal needle holder (40), which releasably holds the needle (22) such that a longitudinal segment (42, 142) of the needle (22) runs alongside the needle-guide surface (36, 136), such that sliding of the needle-guide surface (36, 136) distally along the body-portion surface advances the needle (22) within the body portion beneath the body -portion surface at a maximum depth set by the needle guide tool (30, 130, 230, 330). Other embodiments are also described.

Abstract: A suturing needle having a substantially circular cross-section and a non-smooth profile, and methods of suturing with the needle using a rotational needle driver. The profile of the needle may include a plurality of indentations that form protruding ridges along a longitudinal length of the needle. These ridges may match grooves within rollers of the needle driver. The suture needle may further include a tapered transition portion extending from a proximal end of the needle to cover at least a portion of a suture thread transition portion on the needle. The tapered transition portion is flexible and provides a smooth transition from the suture thread diameter to the needle diameter, so that the rollers may engage the needle in one smooth motion.
