US Classification:

604192, 604110, 604198

Abstract:

A fixed needle syringe has a syringe barrel with its distal portion modified to accept a needle protective housing. In particular, the distal portion is formed with the a groove dimensioned to accept a collar that is attached to the housing. The inside surface of the collar is provided with a number of flanges that fit within the groove formed at the distal portion of the syringe barrel of the fixed needle syringe. Protrusions are provided at the inside surface of the collar to frictionally act against the syringe barrel, so that the needle protective housing does not freely rotate, but is rotatable relative to the syringe barrel by the application of a predetermined torque to either the collar or the housing attached thereto. An internal hook is provided in the housing to grasp the needle of the syringe, when the housing is pivoted to cover the needle extending from the needle hub of the syringe. Coacting locking members are provided at the base of the housing and the outside of the collar for fixedly retaining the housing relative to the collar, once the housing has been pivoted along the alignment position of the syringe.

Abstract:

A fluid reservoir for a medical infusion system includes an expandable elastomeric bladder defining a chamber for receiving and containing a volume of therapeutic substance and exerting pressure thereon to dispense the therapeutic substance from the bladder. The bladder has preferably a single port formed through the thickness thereof. A bi-directional valve is in fluid communication with the chamber of the elastomeric bladder and is used for filling the bladder chamber with the therapeutic substance and for connecting to a catheter assembly for dispensing the therapeutic substance to a patient undergoing treatment. The single port of the elastomeric bladder is connected to a medical grade flexible tubing, which is also connected to the bi-directional valve.

Assignee:

Ethicon, Inc. - Somerville NJ

International Classification:

A61B 18/08

US Classification:

606 28

Abstract:

A system for treating uterine disorders includes a balloon catheter having a cannula with a proximal end and a distal end, and an inflatable balloon secured over the distal end of the cannula. The device includes a heating assembly coupled with the distal end of the cannula and disposed inside the inflatable balloon, and an impeller disposed inside the heating assembly. In one embodiment, the heating assembly includes an elongated heating tube having a heating film covering an outer wall thereof, at least one fluid inlet extending though the outer wall and a fluid outlet located at a distal end of the elongated heating tube. The impeller is rotatable for drawing fluid through the at least one fluid inlet and into the elongated heating tube for heating the fluid, and discharging the heated fluid from the fluid outlet for circulating the fluid throughout the inflatable balloon.

US Classification:

604 9904

Abstract:

A system for treating uterine disorders includes a catheter with a cannula having a proximal end and a distal end, and a degassing system in communication with the distal end of the cannula. The degassing system has a fluid insertion path having a first check valve and a gas filter, and a fluid extraction path that is separate from the fluid insertion path and includes a second check valve. The catheter may include an inflatable balloon secured to the distal end of the cannula with the degassing system in communication with the inflatable balloon. In one embodiment, a heating assembly is disposed inside the inflatable balloon for heating the fluid introduced into the balloon.

US Classification:

600 37

Abstract:

A surgical implant and method for its use. The surgical implant includes a biocompatible mesh having first and second ends, a length greater than a width, and a centering device including a solid, button-like element having opposing first and second surfaces and a peripheral outer edge extending therebetween. The centering device further includes a filamentary element having first and second ends fixedly secured to the peripheral edge of the button-like element so as to form a loop therebetween. The filamentary element is woven through the mesh at its longitudinal center in a direction perpendicular to the length of the mesh.

International Classification:

A61F 2/00

Abstract:

A method of implanting a surgical mesh in tissue includes providing an implant having an insertion aid connected with an end, and providing an insertion device having a handle, an actuator, an elongated shaft, and a cutting element. The elongated shaft has an outer wall with an opening for receiving the insertion aid. The method includes inserting the insertion aid into the opening of the shaft for connecting the implant with the insertion device, forming a surgical opening in tissue, advancing the distal end of the elongated shaft and the implant connected with the insertion device through the surgical opening, and engaging the actuator for moving the cutting element from a first position to a second position for severing the insertion aid from the end of the implant.
