An apparatus and method for minimally invasive suturing is disclosed. A suturing device for minimally invasive suturing includes proximal section having a proximal end, a distal end, and a longitudinal axis therebetween; a suture head assembly extending from the distal end of the proximal section; a suturing needle having a pointed end and a blunt end, the suturing needle capable of rotating about an axis approximately perpendicular to a longitudinal axis of the proximal section, wherein the pointed end of the suturing needle is positioned within the suture head assembly prior to and after rotation of the suturing needle; and an actuator extending from the proximal end of the proximal section to actuate a drive mechanism having a needle driver for engaging and rotating the suturing needle.

Apparatus and method for minimally invasive suturing

A tissue closure device includes a pusher assembly having a drive arm extending from a drive shaft and a needle driver at a distal end of the drive arm, wherein the needle driver is capable of releasably engaging and rotating a suturing needle having a pointed end and a blunt end about a rotational axis and a cartridge having a protective housing and the suturing needle, the cartridge extending from a distal end of a cartridge holder assembly and releasably attached to the cartridge holder assembly. A pointed end of the suturing needle may be positioned within the protective housing before and after a complete rotation of the suturing needle about the rotational axis. A removable electronic module may be provided controlled by an actuator that mechanically engages the drive shaft to rotate the drive shaft and the needle driver, thereby rotating the suturing needle about the rotational axis.

Systems and methods for tissue closure

A system and associated method for concentrating and separating components of different densities from fluid containing cells using a centrifuge includes a container defining a cavity for receiving the fluid. The container has a top, a sidewall extending from the top, and a bottom disposed opposite the top and in sealing engagement with the sidewall. An insert is slidably disposed in the cavity of the container and defines a lumen through the insert. The lumen, which includes a hole and a funnel-shaped upper portion in fluid communication with the hole, forms an open fluid path between opposite ends of the insert. The insert has a density such that upon centrifugation a selected component of the fluid resides within the lumen. A container port is disposed in the top of the container to transfer the fluid into the container and to withdraw a fluid component other than the selected component from the container. The system includes a manifold that includes a manifold port, a vent to vent the container, and a connector to couple to the container port. A cannula is receivable in the manifold port and extendable through the container port into the container and into the lumen of the insert to withdraw the selected component from the lumen.

Cell concentration devices and methods including a syringe and a syringe holder

Devices and methods for minimally invasive suturing are disclosed. One suturing device for minimally invasive suturing includes a proximal section a distal end, and an intermediate region therebetween. The device includes a suture head assembly having a suturing needle with a pointed end and a second end. The suturing needle is capable of rotating about an axis approximately perpendicular to a longitudinal axis of the device, wherein the pointed end of the suturing needle is positioned within the suture head assembly prior to deployment of guides that are adapted and configured to guide the needle around a circular path when advanced by a drive mechanism having a needle driver for engaging and rotating the suturing needle.

Devices and methods for minimally invasive suturing

A system and associated method for concentrating and separating components of different densities from fluid containing cells using a centrifuge includes a syringe and a syringe holder, the syringe having a proximal top with a luer port, a sidewall extending from the top forming a syringe tube, and a plunger slidably disposed inside the syringe tube, the plunger forming a sealing engagement with the sidewall, the syringe holder defining a cavity for receiving the syringe, wherein a distal end of the syringe tube is at least partially closed by the syringe holder after the plunger is placed inside the syringe tube. The method includes receiving a fluid containing cells in the syringe; placing the syringe and syringe holder into a centrifuge;

Apparatus and method for tissue closure

An apparatus and a method for surgical fastening is disclosed. An illustrative apparatus for tissue suturing includes a cartridge having a suturing needle having a pointed end and a blunt end, the suturing needle capable of rotating about an axis, a reciprocating needle drive, and an actuator capable of releasably engaging the needle drive to rotate the needle. A method for suturing tissue is provided that includes placing a suturing device having a cartridge containing a suturing needle to span at least one tissue segment, activating an actuator to cause rotational movement of the suturing needle through the at least one tissue segment, and deactivating the actuator to stop an advancing movement of the suturing needle to cause a suturing material to be pulled through the at least one tissue segment forming a stitch.
