A device having a sheath, a medical device, a stylet, a handle and a plunger device. The handle includes portions connected proximal ends of the sheath, the medical device and the stylet and a chamber portion connected to the actuator. The chamber portion includes a volume of space configured to volumetrically connect to at a lumen of the medical device, the sheath or the stylet and a plunger device configured to be slidably received within the chamber portion. The plunger device is able to pneumatically isolate a proximal portion of the volume of space from a distal portion of the volume of space. Proximal movement of the stylet and the plunger device cause a suction effect (i.e., reduced pressure) at the distal end of the sheath, the medical device and/or the stylet.

Needle handle with vacuum chamber

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. First and second rollers are rotatably mounted parallel with each other in the frame and are configured to engage therebetween a shaft of a needle formed in a helical shape. The first and second rollers are configured to counter-rotate. The needle is revolvable eccentrically around the first roller responsive to counter-rotation of the first and second rollers. A drive mechanism is secured to the frame and is configured to move the frame.

Suturing apparatus and method

A device having a sheath, a medical device, a stylet, a handle having a chamber portion and a plunger device. The handle connects to proximal ends of the sheath, the medical device, and the stylet. The chamber portion includes a volume of space configured to volumetrically connect to at a lumen of the medical device, the sheath or the stylet. The plunger device slides and moves within the chamber portion. The plunger device is able to pneumatically or hydraulically isolate a proximal portion of the volume of space from a distal portion of the volume of space. Proximal movement of the stylet and the plunger device cause a suction effect (i.e., negative or reduced pressure) at the distal end of the sheath and/or the medical device.
