Abstract: An electrosurgical system can include an electrosurgical generator, a feedback circuit or controller, and an electrosurgical tool. The feedback circuit can provide an electrosurgery endpoint by determining the phase end point of a tissue to be treated. The electrosurgical system can include more than one electrosurgical tool for different electrosurgical operations and can include a variety of user interface features and audio/visual performance indicators. The electrosurgical system can also power conventional bipolar electrosurgical tools and direct current surgical appliances.

Abstract: Phase end point determination is provided to automatically halt the application of energy to tissue. Prior to the application of energy, the phase end point determination is identified by measuring the product of permittivity and conductivity of the tissue to be treated.

Abstract: A medical treatment administration system for delivering a medical treatment to a patient. The system has a medical device, an electronic processor coupled to the medical device, and a sensor coupled to the processor. The sensor receives one or more signals which it transfers to the processor. The signals can be derived from the patient's physiological condition and/or the environment of the patient. The processor receives the signals and performs a calculation of the signal. Based on the result of the calculation, the processor regulates the distribution of medical treatment to the patient over a period of time.

Abstract: Embodiments of a catheter insertion device are discussed comprising: an approximately hollow cylindrical catheter sleeve, at whose distal end a catheter is attached: a needle sleeve with a hollow needle, which is attached thereto and which, when ready for use, extends through the catheter sleeve and the catheter, and; a needle protective element that is arranged inside the catheter sleeve while being able to move on the needle. Said needle protective element has an engaging section that engages with an engaging device, which is formed in the vicinity of the needle tip, when the hollow needle is withdrawn from the catheter sleeve. A check valve is placed inside the catheter sleeve between the catheter and the needle protective element. The hollow needle, when ready for use, extends through said check valve, and the check valve automatically closes once the needle is withdrawn.

Abstract: Systems and methods for delivering drugs or other substances to target locations outside of blood vessel lumens or other body lumens. In some embodiments, a catheter having a penetrator is advanced into the body lumen and the penetrator is then advanced from the catheter toward a target location outside of that body lumen. The substance is then delivered through a the penetrator itself or through a delivery catheter that has been advanced through the penetrator to the target location. In other embodiments, the blood vessel or other body lumen is blocked at spaced-apart first and second locations and a quantity of the substance is introduced into the closed-off body lumen between the blocked first and second locations. The substance then diffuses into or through the wall of the vessel or body conduit to reach the target location.

Abstract: A retractable catheter for use in an implant delivery system, the catheter including an elongate tubular sheath made of a relatively flexible material, and a pull element for transmitting a pull force to the sheath to retract it longitudinally. The pull element includes an end portion disposed in the relatively flexible material, at least the thickness of the end portion being substantially less than its length.

Abstract: An auto-injector confines all functional components inside an enclosed housing, to keep its needle out-of-sight, at all times. Within the housing, a needle holder positions a needle at a location. A drive mechanism then simultaneously engages the needle with a fluid source and accelerates it with a predetermined momentum for insertion into a patient. After fluid delivery, the withdrawn needle is moved to storage within the housing for subsequent disposal.

Abstract: Embodiments of an implantable electrolytic pump include a first expandable diaphragm and a second flexible diaphragm, and first and second chambers each for containing a fluid, wherein the first expandable diaphragm separates the first and second chambers and provides a fluid barrier therebetween, and the second chamber is formed between the first expandable diaphragm and the second flexible diaphragms. The pump may further include electrolysis electrodes within the first chamber for causing generation of a gas therein and to thereby expand the expandable diaphragm so that fluid is forced from the second chamber into a cannula.

The invention also provides for methods of making and methods of using the same.

Abstract: An apparatus having a tube section and an expanded end. The tube section is flexible while the end section is rigid. The apparatus has a central bore, large enough to loosely receive an endoscope tube, and the end section has two peripheral bores which communicate with the central bore. There is a collar around the central bore which allows formation an air- and water-tight seal with the head of an endoscope. The tube may be fenestrated at its proximal end and may include medial pleats. This apparatus is mainly used by: sliding an endoscope into the central bore until the endoscope head forms an air- and water-tight seal with the central bore; connecting a lavage tube to one peripheral bore and a vacuum tube to the other peripheral bore; inserting the endoscope and the apparatus into a GI tract; and manually controlling the apparatus to apply lavage and vacuum.

Abstract: Disclosed is a therapeutic fluid reservoir to be used with an ambulatory portable infusion device. The reservoir includes a pliable shell defining a varying inner volume that varies based on the volume of therapeutic fluid held inside the reservoir, the varying inner volume having a predetermined maximum volume for containing a corresponding volume of therapeutic fluid and an outlet port for communicating fluid from the reservoir to a patient, the varying inner volume decreasing upon therapeutic fluid being communicated through the outlet port. Upon the reservoir reaching the predetermined maximum volume when being filled with therapeutic fluid, any therapeutic fluid in excess of the predetermined maximum volume driven into the reservoir causes a substantially corresponding amount of therapeutic fluid to exit out of the reservoir via the outlet port and/or at least one other port provided in the pliable shell.

Abstract: A percutaneous gastrostomy catheter includes an internal retainer configured to be maintained pressed against the stomach wall and to disengage itself from a tubing by biodegradation; and an external flange, traversed by the tubing, configured to be pressed against an external face of the abdominal wall and exert, in cooperation with the internal retainer, a pressure adapted to press an external face of the stomach wall against an internal face of the abdominal wall. The internal retainer includes an internal flange. A first face of the internal flange is configured to be pressed against an internal face of the stomach wall, the internal flange being detachable from the tubing under the effect of a simple pulling force. The internal retainer also includes an end piece pressed against the second face of the internal flange, such that the internal flange is between the end piece and the external flange, the end piece being made of a completely biodegradable copolymer or polymer having a bond with the tubing.
