Vascular clamp for caesarian section
First Claim
1. An arterial clamping system comprising:
- a. a clamping device for at least partially occluding a target vessel in a patient'"'"'s body, comprising a pair of opposed pressure-applying members configured to at least partially occlude the target vessel by applying pressure thereto, with at least one of the pressure-applying members having a floating, pressure-applying jaw with a continuous pressure applying surface movably mounted thereto and having a resilient connection between the floating, pressure-applying jaw and the pressure applying member, the resilient connection being at least partially surrounded by side walls extending from the continuous pressure applying surface of the floating, pressure-applying jaw and toward the pressure-applying member, wherein the side walls have a plurality of slots and the at least one of the pressure-applying members has a plurality of pins projecting from lateral edges thereof that are disposed in the slots for guiding movement of said floating, pressure-applying jaw; and
a sensor on at least one of the pressure-applying jaws for locating the target vessel, wherein the sensor is movably mounted to a distal end of the clamping device; and
b. a sensor controller operatively connected to the sensor and comprising a source of power.

Abstract
The invention provides devices, systems and methods for clamping arteries which are useful in reducing or abolishing blood flow in an artery, and may be used to control hemorrhage following a caesarian delivery. A clamping device embodying features of the invention includes a pair of clamping members with opposed pressure-applying members having facing pressure-applying surfaces, at least one of which is a yieldable pressure-applying surface. The yieldable pressure-applying surface is preferably resilient. The clamping members are configured to adjust the distance between pressure-applying surfaces, and a blood flow sensor is disposed on at least one of the pressure-applying members to aid in locating the target artery and also to monitor blood flow through the artery. The clamping device is particularly suitable for occluding uterine arteries by compressing the broad ligament which contains the uterine artery and which is connected to the patient'"'"'s uterus with the arterial clamp.

6. A device for treating a female patient'"'"'s uterus after caesarian section by occluding the patient'"'"'s uterine artery comprising:
-
a pair of opposed clamping elements having pressure-applying jaws configured to at least partially occlude a target uterine artery by applying pressure thereto; at least one of the pressure-applying jaws being a floating jaw movably mounted to one of the clamping elements and having a resilient connection with the one of the clamping elements; and a blood flow sensor disposed on at least one of the pressure applying jaws for locating the target uterine artery to be clamped, wherein the floating jaw has side walls extending from a clamping surface thereof, the side walls being slideable over lateral edges of the one of the clamping elements, wherein the opposed side walls of the floating jaw have slots that receive pins projecting from the lateral edges of the one of the clamping elements. - View Dependent Claims (7, 8)

9. A device for treating a female patient'"'"'s uterus by occluding a uterine artery thereof comprising:
-
a pair of opposed clamping elements; at least one of the clamping elements having a floating pressure-applying jaw movably mounted thereto, wherein the jaw includes a continuous pressure-applying surface and is adapted to at least partially occlude a target uterine artery by applying pressure thereto; a resilient connection between the clamping element and the jaw movably mounted thereto, the resilient connection being at least partially surrounded by side walls extending between the continuous pressure-applying surface of the floating pressure-applying jaw and one of the opposed clamping elements; a guide assembly coupled with the floating pressure-applying jaw for guiding movement of the floating pressure-applying jaw toward and away from the at least one of the opposed clamping elements; and a blood flow sensor disposed on at least one of the pressure applying jaws for locating the target uterine artery to be clamped, wherein the blood flow sensor is attached to the floating pressure-applying jaw for moving with the floating pressure-applying jaw, wherein the floating pressure-applying jaw comprises opposing side walls extending from the continuous pressure-applying surface thereof to lateral edges of the at least one of the clamping elements, wherein the guide assembly comprises slots formed in the opposing side walls of the floating pressure-applying jaw and pins projecting from the lateral edges of the at least one of the clamping elements, and wherein the slots receive the pins. - View Dependent Claims (10, 11, 12, 13, 14)

15. A clamping device for occluding a target vessel comprising:
-
a pair of opposed pressure-applying members; at least one of said pressure-applying members having a distal end including a yieldable pressure-applying surface; a guide assembly coupled with the at least one of said pressure-applying members for guiding movement of said yieldable pressure-applying surface toward and away from the at least one of said pressure applying members; further comprising a floating jaw coupled with the at least one of said pressure-applying members, wherein said floating jaw includes said yieldable pressure-applying surface wherein said floating jaw is mounted over an inner face of the at least one of said pressure-applying members, wherein said floating jaw includes side walls extending from said yieldable pressure-applying surface toward the at least one of said pressure-applying members associated therewith, wherein said guide assembly comprises slots formed in each of said side walls of said floating jaw, and wherein said slots in each of said side walls are parallel with one another and extend away from said yieldable pressure-applying surface. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
