Suturing apparatuses configured to suture biological tissue, such as an anatomical valve, can include an elongate member having a proximal end, a distal end, one or more arms, and one or more needles. A protective member may be used to inhibit contact between a distal end of a needle and surrounding tissue. Methods for suturing bodily tissue such as an anatomical valve may be performed with the suturing apparatuses. The suturing apparatuses may be used to suture adjacent valve leaflets or the base of a valve in order to treat or repair the valve.
1. A suturing device, comprising: an elongate member comprising a distal end;at least two arms connected with the elongate member near the distal end for movement between a retracted position and an extended position, each of the at least two arms comprising at least one suture mount located near a
1. A suturing device, comprising: an elongate member comprising a distal end;at least two arms connected with the elongate member near the distal end for movement between a retracted position and an extended position, each of the at least two arms comprising at least one suture mount located near a free end of each of the at least two arms and configured to releasably retain a suture portion;at least two needles each configured to move between a retracted position and a deployed position to retrieve the suture potion retained in the at least one suture mount when each of the at least two needles is moved from the retracted position to the deployed position and returned to the retracted position; anda protective member configured to inhibit contact between a distal end of each of the at least two needles and surrounding tissue during at least a portion of the movement of each of the at least two needles from its retracted position toward its deployed position;wherein the protective member is moveable into alignment with each of the at least two arms; andwherein each of the at least two arms in its extended position has a free end, the free ends being spaced apart from each other, and the protective member is configured to house the at least two needles and move between locations adjacent each of the free ends of the arms. 2. The suturing device of claim 1, wherein the protective member is configured to move between a retracted position and an extended position. 3. The suturing device of claim 2, wherein the protective member is configured to move from its retracted position to its extended position before the needles are deployed. 4. The suturing device of claim 2, wherein the protective member is configured to move from its retracted position to its extended position while the at least two needles are being moved from their retracted positions to their deployed positions. 5. The suturing device of claim 2, wherein the protective member comprises a sleeve and the at least two needles are configured to extend through the sleeve when the at least two needles are in their deployed positions. 6. The suturing device of claim 2, wherein the protective member is configured to partially surround a circumference of each needle when the at least two needles are in their deployed positions. 7. The suturing device of claim 1, wherein each arm comprises a first suture mount and a second suture mount located near a free end of each arm and configured to releasably retain a second suture portion, one of the at least two needles being configured to move between a retracted position and a deployed position to retrieve the second suture potion retained in the second suture mount when the one of the at least two needles is moved from the retracted position to the deployed position and returned to the retracted position. 8. The suturing device of claim 1, wherein the protective member is configured to partially surround the at least two needles when the at least two needles are in their deployed positions. 9. The suturing device of claim 8, wherein the protective member has a generally U-shaped cross-section. 10. The suturing device of claim 1, wherein the suturing device comprises six arms and twelve needles. 11. The suturing device of claim 1, wherein the protective member comprises a pair of lumens.
