ENDOSCOPIC SUTURING DEVICE
First Claim
1. A suturing device, comprising:
- a head including a proximal end portion and a distal end portion, the distal end portion defining a first opening, the proximal end portion defining a second opening, the proximal end portion of the head configured to be removably coupled to a distal end portion of an elongate medical device configured to be disposed within a body lumen of a patient; and
a curved carrier member movably disposed at least partially within the distal end portion of the head, the carrier member being movable from a first position in which the carrier member is disposed substantially within the distal end portion of the head to a second position in which a first portion of the carrier member is moved out through the first opening and disposed adjacent the second opening and a second portion of the carrier member is disposed within the distal end portion of the head, the carrier member being configured to receive a needle coupled to a suture when in the first position and configured to pass the needle and a portion of the suture through a tissue when moved from the first position to the second position.

Abstract
A suturing device for use in endoscopic procedures includes a head configured to be removably coupled to an elongate medical device and an actuator coupled to the head via an elongate flexible sheath. The suturing device is configured to pass a needle and suture through a selected tissue site upon actuation of the actuator. In another embodiment, a suturing device includes a head and a retaining portion configured to receive a guide wire. The suturing device can be inserted into a patient'"'"'s body using the guide wire to guide and help position the head of the suturing device. In such an embodiment, the suturing device can also include an expandable member coupled to the head and that is configured to be expanded within a body lumen of a patient to help maintain a position of the head within the body lumen.
