1. A suturing system, comprising:
- a suturing device comprising an elongate body having a proximal end and a distal end;
a plurality of arms near the distal end, wherein each arm is configured to move between a first position wherein the arm is retracted within the elongate body, and a second position wherein the arm has a free end extending away from the elongate body, each arm comprising at least one suture mount at the free end;
a plurality of needles, each needle configured to move between a retracted position in which the needle is within the elongate body to a deployed position in which the distal point of the needle extends out of the elongate body and into a corresponding suture mount; and
a first sheath adapted to surround at least a portion of the elongate body;
a second sheath adapted to surround at least a portion of the first sheath;
a plurality of suture portions, wherein each suture portion has a suture end releasably retained within a suture mount of a corresponding arm, each suture portion extending from a corresponding suture end, between the first sheath and the second sheath, to a position proximal to at least the second sheath.

Abstract
Suturing devices and systems used to close openings into a biological structure. The suturing device can comprise an elongate member having a proximal end, a distal end, one or more arms, and one or more needles. One or more sheaths may be used with the device to maintain or substantially maintain haemostasis while the device is used and while a procedure is performed in the biological structure.

9. A suturing device for suturing an opening in a heart wall, comprising:
-
an elongate body comprising a proximal end and a distal end, a first section at the distal end, a second section proximal to the first section, and a distally facing body surface between the first and second sections; a plurality of arms near the distal end in the second section, wherein each arm is configured to move between a first position wherein the arm is retracted within the elongate body, and a second position wherein the arm has a free end extending away from the elongate body, each arm comprising at least one suture mount at the free end and configured to releasably retain a suture portion; and a plurality of needles, each needle configured to move between a retracted position in which the needle is within the elongate body to a deployed position in which a distal point of the needle extends out of the elongate body and into a suture mount; wherein the second section has a larger outer dimension than the first section and the distally facing body surface is configured to press against an external surface of a heart when the first section is advanced into the opening in the heart. - View Dependent Claims (10, 11, 12, 13)
