Patent number: 8052718Abstract: A non-invasive blood vessel occlusion device includes a pair of pressure-applying members with opposed tissue-contacting surfaces, a supporting shaft configured to adjust the distance between tissue-contacting surfaces, and at least one sensor for locating a blood vessel disposed on at least one pressure-applying member. Blood vessels may be occluded by indirectly compressing the artery by compressing tissue near to an artery. The occlusion device finds use in, for example, treating uterine disorders and conditions which may be treated by occlusion of the uterine arteries. A uterine artery may be accessed via a body cavity, such as a patient's vagina, and may be occluded by compressing a portion of the vaginal wall around a portion of a uterine artery.Type: GrantFiled: November 19, 2002Date of Patent: November 8, 2011Assignee: Vascular Control Systems, Inc.Inventors: Fred H.

Patent number: 7651511Abstract: 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.Type: GrantFiled: February 5, 2003Date of Patent: January 26, 2010Assignee: Vascular Control Systems, Inc.Inventors: Fred H.

Patent number: 7354444Abstract: Devices, systems and methods for temporarily reducing or abolishing blood flow by occluding blood vessels are provided. A blood vessel-occlusion device embodying features of the invention includes a deployable pressure-applying member with a location sensor, and an applicator. The location sensor is configured to detect a blood vessel, which may be occluded by compression from the pressure-applying member. A pressure-applying member may be released from the applicator, with blood-vessel compression maintained after release. The applicator is configured to engage a guide, such as a tenaculum, to aid in the placement and operation of the applicator. A pressure-applying member may also engage the guide. The invention finds use in, for example, treating uterine disorders and conditions which may be treated by occlusion of the uterine arteries, such as uterine fibroids, dysfunctional uterine bleeding, post-partum hemorrhage, and bleeding associated with caesarian section.Type: GrantFiled: November 19, 2002Date of Patent: April 8, 2008Assignee: Vascular Control Systems, Inc.Inventors: Fred H.

Patent number: 7229465Abstract: The invention provides devices, systems and methods for occluding arteries without puncturing skin or vessel walls. The devices, systems and methods for occluding arteries are configured to be applied to arteries externally of the arteries. Occlusion may be temporary or permanent, and may be partial or complete. Clamping a device to tissue near to an artery is effective to compress tissue around the artery and to indirectly compress the artery. The methods, devices and systems of the invention find use in, for example, treatment of uterine disorders and conditions which may be treated by occlusion of the uterine arteries. A uterine artery may be accessed via a patient's vagina by compressing a portion of the vaginal wall around a portion of a uterine artery to occlude a uterine artery. Clamping of an artery may also be performed by clamping a device directly onto an artery.Type: GrantFiled: March 28, 2002Date of Patent: June 12, 2007Assignee: Vascular Control Systems, Inc.Inventors: Fred H.

Patent number: 6638286Abstract: A ligation device includes a cannula having first and second extendable members and a Doppler wand. The Doppler wand permits an anatomical vessel, such as a blood vessel, to be located in close proximity to the distal end of the cannula. The extendable members are extendable on two opposite sides of the vessel. A length of ligation material, such as suture material, extends through the first extendable member, and is attached to a detachable element mounted to the distalmost end of the extendable member. The second extendable member includes a snare. The first extendable member includes curved portions which, when the member is extended distally, extend the detachable element into position for the snare so that the snare can grab the loop. Once ensnared, the detachable element is released from the first extendable member, which pulls the ligation material around the vessel. The ligation device does not require prior visualization or dissection of the area around the vessel.Type: GrantFiled: November 16, 2000Date of Patent: October 28, 2003Assignee: Vascular Control Systems, Inc.Inventors: Fred Burbank, Michael L.
