摘要:
Devices and methods are disclosed for treating a uterine disorder which receive its blood supply from a uterine artery. In particular, uterine fibroids are effectively treated by occluding the uterine arteries using trans-vaginal, trans-uterine, transrectal, or retroperitoneal approaches. The devices and methods are advantageous because the inventive procedures may be performed by a patient's gynecologist in the course of treatment, avoiding the need for referrals to specialist practitioners and for more radical treatments, such as hysterectomies. The methods include both temporary and permanent occlusion of the arteries. A cannula carries an imaging device and a member which will easily penetrate tissue, the member including a device which partially or completely, and temporarily or permanently, occludes a uterine artery.

摘要:
A device for accessing and for isolating a desired site within a patient's body, and for obtaining a body of tissue from a patient at the site that includes an electrosurgical cutting electrode near the distal tip of a shaft, an anchoring mechanism and an electrosurgical side-cutting device. Methods are provided for accessing a target site within a patient's body, anchoring a body of tissue at the site, and isolating the body of tissue at the site. The method may be performed for a surgical biopsy or lumpectomy at the target site within a patient's body.
摘要:
An automated system and method of cryopreservation and reanimation of oocytes, embryos, or blastocysts is disclosed. One or more oocytes or embryos are positioned in a processing container, the processing container being configured to allow fluid to flow into and out of the processing container, where two or more fluids flow into and out of the processing container with oocytes or embryos therein. The temperature of the fluid may be controlled in the processing container according to predetermined requirements. The flowing of the fluids may be controlled by a central controller adapted to control one or more valves.
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. A tenaculum-like element can be further included which secures the system to the patient's cervix.
摘要:
A method of treating a uterine disorder comprising non-permanently occluding a uterine artery with a resorbable embolic mass for a therapeutically effective time period. The occluding step includes selectively positioning the resorbable embolic mass within the uterine artery, and monitoring positioning of the resorbable embolic mass at a desired location within the uterine artery. The monitoring step may include using ultrasound or magnetic resonance imaging (MRI) for positioning the resorbable embolic mass at the desired location within the uterine artery. The resorbable embolic mass may be swellable and may be formed of a polymeric material selected from the group consisting of polylactic acid, polyglycolic acid, polyethylene glycol, or copolymers thereof.

Instruments for performing percutaneous biopsy procedures are disclosed, which have advantageous features for improving functionality and performance over prior art devices. These instruments comprise two types, single-use devices, and multiple-use devices having active tissue capture capability. Improved features include the ability to retrieve and evaluate multiple tissue samples during a single insertion procedure, without physical handling of the samples, as well as constructional features, such as a molded tissue cassette housing, variant vacuum port embodiments suited for different tissue environments, and a method for backflushing the instrument to remove biological debris, among others.
摘要:
Non-permanent occlusion of the uterine arteries is sufficient to cause the demise of uterine myomata without unnecessarily exposing other tissues and anatomical structures to hypoxia attendant to prior permanent occlusion techniques. A therapeutically effective transient time of occlusion of a uterine artery to treat uterine fibroid tumors is from 1 hours to 24 hours, and preferably is at least about 4 hours. A therapeutically effective temporary time of occlusion of a uterine artery to treat uterine fibroid tumors is from 1 day (24 hours) to 7 days (168 hours), and preferably is about 4 days (96 hours). By invaginating the tissues of the vaginal wall up to or around a uterine artery, collapse of the uterine artery can be achieved without penetrating tissue of the patient.
摘要:
Implantable devices and methods of use are disclosed for marking the location of a biopsy or surgery for the purpose of identification. The methods include providing a biodegradable radiodense implant and taking a tissue sample from a biopsy site within a breast of a patient. The biodegradable implant is then positioned at the biopsy site. The tissue sample is tested and the biopsy site is then relocated. In one embodiment, the entire implant is radiodense. In another embodiment, the entire implant is biodegradable. Methods of using a biodegradable implant having a radiodense material and a biodegradable implant that is visible using an imaging system are also included.
摘要:
Naso-pharyngeal devices for treating sleep apnea can perform two functions simultaneously: keeping an open airway through an inner lumen of the device; and support for the tissue in the airway, because keeping the tissue from completely collapsing creates the possibility of some air movement around the device in the critical areas associated with obstructive sleep apnea.
