摘要:
An implantable article and method of use are disclosed to treat urological disorders. The biocompatible device includes a sling assembly configured to be minimally invasive and provide sufficient support to the target site. In addition, the configuration of the sling assembly also allows the position of the sling to be permanently changed during and/or after implantation.
摘要:
A design and method of manufacture is disclosed for an insulated electrode used during surgical procedures. The electrode includes a durable electrical insulation element that can withstand the range of temperatures generated during an electrosurgical procedure. Such insulation characteristics include resistance to meltback and manufacturability to ensure the device is biocompatible and non-toxic so as to prevent adverse reactions in both patients and users of the device. The insulated electrode further includes properties that reduce the incidence of scope damage caused by the intensity of heat generated during the cutting and coagulation cycles.
摘要:
A bio-compatible and bioresorbable stent is disclosed that is intended to restore or maintain patency following surgical procedures, traumatic injury or stricture formation. The stent is composed of a blend of at least two polymers that is either extruded as a monofilament then woven into a braid-like embodiment, or injection molded or extruded as a tube with fenestrations in the wall. Methods for manufacturing the stent are also disclosed.
摘要:
A device for dilating at least an obstructed portion of a urethra includes a hollow core member (24) with opposed open ends permitting urination therethrough from the bladder, a confining covering (33) disposed on the hollow member (24) having a length of at least that of the obstructed portion and having hydrophilic means (32) integrally associated therewith. The hydrophilic means (32) is capable of absorbing water and gradually expanding for at least 30 minutes whereby the outer surface of the confining covering (33) expands radially and outwardly, after insertion into the urethra, until dilation of the obstructed portion occurs to a desired diameter and configuration. Methods for dilating an obstructed portion of the urethra and for treating benign prostatic hyperplasia are also provided.
摘要:
An apparatus for electrosurgical incision of a stricture within or adjacent to a body lumen, which comprises an electrically conducting, deflectable wire (1) associated with an introducer (6) for introducing the wire into the body lumen, wherein a proximal portion of the wire is deflectable outwardly relative to the introducer, and a source of RF electric current connected to the wire whereby RF electric current may be transmitted through the wire when it is in the deflected position.
摘要:
A device for treating leakage from an external orifice in the body of a patient which comprises a first member (1) having a body-contacting first surface (2) and an opposing second surface (3) about an aperture (4), which first surface (2) is attachable to the patient with said aperture (4) positioned over said orifice, and a second member (7) integral with said second surface (3) which second member (7) comprises a valve (17) mounted over said aperture (4), which valve (17) has a closed position which prevents leakage of fluid through the device and an open position which allows fluid to flow through said aperture (4) when desired, the closed and open positions being achievable without removing the device from the body of the patient.
摘要:
An apparatus and method for interstitial treatment and diagnosis in organs utilizing a flexible cannula (12) having an interstitial locking means (16) thereon. The apparatus includes a shaft for insertion into a body passage adjacent to the organ to be treated and adapted to guide cannula into the organ. The shaft is also adapted to receive an endoscope (28) to visualize insertion of the cannula. The cannula locking means includes a locking member which extends from the distal end of the cannula in response to relative motion between parts of the cannula.
摘要:
Appareil chirurgical destiné à la mise en place d'un instrument dans une cavité de l'organisme et qui se compose (i) d'un dispositif de mise en place d'un élément (20) de forme allongée dont l'extrémité (20b) découvrable perce les tissus, d'un premier accouplement (46) contigu à l'extrémité, et d'une tige (22) permettant de découvrir l'extrémité; et (ii) d'un instrument de forme allongée (40) pour la mise en place, qui comporte un deuxième accouplement (44) conçu pour s'adapter au premier (46) de manière à réaliser une liaison bout à bout du dispositif et de l'instrument afin de positionner ledit instrument dans la cavité de l'organisme. Il s'agit de préférence d'un instrument sus-pubien, à mettre en place dans la vessie.
