1. A method for clamping tissue, the method comprising the steps of: providing a medical system comprising a housing defining a longitudinal axis extending between proximal and distal ends of the housing, first and second jaws slidably and pivotally connected to the housing, a driver engaged with the first and second jaws for longitudinal movement and rotational movement of the first and second jaws, and an elongated drive wire selectively connected to the driver for longitudinal movement therewith;advancing the drive wire distally to translate the first and second jaws distally relative to the housing;restricting distal translation of the first and second jaws relative to the housing;advancing the drive wire distally to rotate the first and second jaws away from each other;positioning the tissue between the first and second jaws;retracting the drive wire proximally to rotate the first and second jaws towards each other to clamp the tissue therebetween;retracting the drive wire proximally to translate the first and second jaws proximally relative to the housing; anddetaching the drive wire from the driver to leave the first and second jaws clamped to the tissue and connected to the housing. 2. The method of claim 1, wherein the step of restricting distal translation of the first and second jaws relative to the housing occurs prior to the step of advancing the drive wire distally to rotate the first and second jaws. 3. The method of claim 2, wherein the housing includes a jaw guide surface guiding movement of the first and second jaws, the jaw guide surface including structure to restrict distal movement of the first and second jaws, and wherein the step of advancing the drive wire distally to rotate the first and second jaws occurs while the structure of the jaw guide surface is restricting distal movement of the first and second jaws. 4. The method of claim 2, wherein the step of restricting distal translation of the first and second jaws relative to the housing also occurs concurrently with the step of advancing the drive wire distally to rotate the first and second jaws. 5. The method of claim 1, wherein the drive wire is advanced distally to translate the first and second jaws distally relative to the housing, then the distal translation of the first and second jaws relative to the housing is restricted, and then the drive wire is advanced distally to rotate the first and second jaws. 6. The method of claim 1, wherein the housing restricts proximal translation of the first and second jaws while the drive wire is retracted proximally to rotate the first and second jaws towards each other. 7. The method of claim 1, further comprising the step of restricting the distal movement of the driver to maintain the clamping of the tissue between the first and second jaws. 8. The method of claim 7, wherein the housing includes a driver guide surface defining a shoulder, and where the driver includes a deflectable tab, and wherein the step of restricting the distal movement of the driver to maintain the clamping of the tissue occurs while the deflectable tab is engaged with the shoulder. 9. The method of claim 8, where the deflectable tab plastically deforms to a position engaged with the shoulder. 10. The method of claim 8, wherein the housing and driver are structured to permit the drive wire to disengage the driver when the deflectable tab is proximal to the shoulder. 11. The method of claim 7, wherein the steps of detaching and restricting occur simultaneously by sufficient proximal force on the drive wire to deflect a locking tab formed on the driver. 12. The method of claim 1, wherein the driver includes a deflectable tab, and wherein the housing includes a driver guide surface defining a shoulder positioned to engage the deflectable tab, and wherein sufficient distal force on the drive wire causes deflection of the deflectable tab such that the deflectable tab moves distally beyond the shoulder. 13. The method of claim 12, wherein the housing is structured to force the deflectable tab to frictional engage the drive wire when the deflectable tab is distal to the shoulder such that the drive wire and the driver move together. 14. The method of claim 1, wherein the step of detaching the wire guide includes placing a proximally directed force on the drive wire. 15. The method of claim 14, wherein the driver includes a socket defined by a locking tab, the socket receiving a distal end of the drive wire, and wherein sufficient proximally directed force causes plastic deformation of the locking tab. 16. The method of claim 1, further comprising a tubular connector slidably receiving the drive wire, the tubular connector slidably housing a connection block, the connection block sized and structured to frictionally engage both the tubular connector and the housing, and further comprising the step of proximally translating the drive wire such that it engages the connection block and proximally translates the connection block out of engagement with the housing. 17. The method of claim 16, wherein connection block includes a bore receiving the drive wire, and wherein the drive wire includes an enlarged distal end having a diameter greater than a diameter of the bore, whereby the enlarged distal end engages the connection block to proximally translate the connection block out of engagement with the housing. 18. A method for clamping tissue, the method comprising the steps of: providing a medical system comprising a housing, first and second jaws, a driver and an elongated drive wire, the housing defining a longitudinal axis extending between proximal and distal ends of the housing, the first and second jaws slidably and pivotally connected to the housing, the driver engaged with the first and second jaws for driving longitudinal movement and rotational movement of the first and second jaws, the housing including a driver guide surface defining a shoulder, the driver including a deflectable tab, the elongated drive wire selectively connected to the driver for longitudinal movement therewith;advancing the drive wire distally to translate the first and second jaws distally relative to the housing and to rotate the first and second jaws away from each other;positioning the tissue between the first and second jaws;retracting the drive wire proximally to rotate the first and second jaws towards each other and to translate the first and second jaws proximally relative to the housing, to clamp the tissue therebetween;retracting the drive wire proximally to plastically deform the locking tab into a position for engagement with the shoulder such that distal movement of the driver is restricted to maintain the clamping of the tissue; anddetaching the drive wire from the driver to leave the first and second jaws clamped to the tissue and connected to the housing. 19. The method of claim 18, wherein sufficient distal force on the drive wire causes deflection of the deflectable tab such that the deflectable tab moves distally beyond the shoulder, whereby the deflectable tab frictionally engages the drive wire such that the drive wire and the driver move together. 20. A method for clamping tissue, the method comprising the steps of: providing a medical system comprising a housing, first and second jaws, a driver, a tubular connector, and an elongated drive wire, the housing defining a longitudinal axis extending between proximal and distal ends of the housing, the first and second jaws slidably and pivotally connected to the housing, the driver engaged with the first and second jaws for driving longitudinal movement and rotational movement of the first and second jaws, the tubular connector slidably housing a connection block, the connection block sized and structured to frictionally engage both the tubular connector and the housing, the elongated drive wire selectively connected to the driver for longitudinal movement therewith;advancing the drive wire distally to translate the first and second jaws distally relative to the housing and to rotate the first and second jaws away from each other;positioning the tissue between the first and second jaws;retracting the drive wire proximally to rotate the first and second jaws towards each other and to translate the first and second jaws proximally relative to the housing, to clamp the tissue between the first and second jaws;detaching the drive wire from the driver to leave the first and second jaws clamped to the tissue and connected to the housing; andretracting the drive wire proximally such that the drive wire engages the connection block and proximally translates the connection block out of engagement with the housing.
