摘要:
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.

A compression and ligation device includes a pair of jaws including one or more Doppler chips oriented to send and receive Doppler signals across the jaws, to assist a practitioner in determining whether or not a uterine artery is between the jaws. A suture leader with an attached suture can be pushed through a channel on one of the jaws, through tissue behind the uterine artery, into another channel on the other jaw, and proximally out the device so that the practitioner can ligate the artery and effect hemostasis.

Medical devices that are coated with an echogenic material that includes an electrically insulative base layer and an echogenic layer demonstrate both improved ultrasonic imaging and protection against RF electrical breakdown. The echogenic layer includes a polymeric matrix that (i) defines a plurality of void spaces, (ii) includes glass microsphere particles, or (iii) both defines a plurality of void spaces and includes glass microsphere particles. Medical instruments exhibit enhanced ultrasonic imaging even when viewed along their lengths.

The invention is directed to a uterine artery clamp and the relatively non-invasive treatment procedure utilizing this clamp. The uterine clamp includes a clamping member having a jaw with tissue-contacting surfaces for applying pressure to target tissue and a stabilizing member which is configured to be inserted into the patient's uterine cervical canal. The clamp may be provided with elongated handles to manually adjust the spacing between the jaw and stabilizer and thereby apply pressure to a uterine artery beneath a bundle of tissue held between the jaw and stabilizer. Uterine clamps embodying features of the invention by be used in procedures for treating uterine disorders such as fibroids, DUB, PPH and the like.
摘要:
A method and device for treating a female patient's uterine disorder by occluding one or both of the patient's uterine artery. The treatment involves occluding one or both of the patient's uterine arteries with an intravaginal device to form a thrombus within the occluded artery or arteries and administering an agent which will prolong the occlusion of the artery or arteries after removal of the occluding device or initiate or accelerate fibroid cell apoptosis (programmed cell death). The intravaginal device has a pair of pivotally connected occluding members, with at least one of the occluding member having a movable occluding element on a distal shaft section of the occluding member.
摘要:
An occluding device is disclosed for occluding a female patient's uterine arteries which have unsymmetrical anatomy with respect to the patient's uterine cervix. The occluding device has a pair of pivotally connected occluding members, with at least one of the occluding member having a movable occluding element on a distal shaft section of the occluding member. The position and orientation of the occluding elements on the distal shaft sections may be adjusted by operative members on the proximal shaft sections of the occluding members to accommodate for asymmetrical uterine artery anatomy. The occluding elements have pressure applying surfaces with one or more blood flow sensors such as Doppler chips which help the physician to better identify the uterine artery and to monitor blood flow therein. A tenaculum-like guiding element configured to be secured within the patient's uterine cervix, may be provided to guide the occluding device to the patient's cervix.

An intravaginal uterine artery occlusion device is used for treating uterine disorders such as fibroids, dysfunctional uterine bleeding, postpartum hemorrhage and the like. A occlusion device has a cervical receptacle with an open distal end for receiving the patients uterine cervix, an elongated shaft having a distal end secured to the closed proximal end of the cervical receptacle, and an inner lumen extending to the distal end of the shaft. The patient's uterine cervix is held within the interior of the receptacle by the application of a vacuum to the interior of the receptacle through the inner lumen of the shaft while the leading edge(s) of the cervical receptacle press against the patient's vaginal fornix to occlude the uterine artery. A blood flow sensor may be provided on the leading edge of the receptacle to aid in locating a uterine artery and to monitor blood flow through the uterine artery.

摘要:
A system is provided for compressing one or both of the uterine arteries of a patient which is at least in part shaped to complement the shape of the exterior of the cervix, which allows the system to be self-positioning. One or more Doppler chips can be mounted or incorporated into the system which permit the practitioner to better identify the uterine artery and monitor blood flow therein. The system includes a pair of pivotally joined elements which can be moved toward and away from the cervix to compress a uterine artery.

Devices, systems and methods for occluding blood vessels include a deployable constrictor having opposed pressure-applying portions, a delivery shaft configured to intravaginally advance the constrictor to the patient's cervix, a location sensor configured to detect a blood vessel, a deployment member for deploying the constrictor about the patient's cervix, and optionally a guide. The constrictor has a first configuration to receive a cervix and a second configuration to apply pressure to the cervical area to occlude a uterine artery by compression from the pressure-applying members. The pressure-applying members may be released from the cervix after a limited therapeutically effective time. The constrictor is for 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 sections.
