Publication number: 20040106892Abstract: An injection apparatus includes components that facilitate injection of relatively viscous materials into a patient. An injection apparatus may include a transition-bore needle apparatus, which has a proximal end, a distal end, and a lumen extending from the proximal end to the distal end, in which the diameter of the proximal end is greater than the diameter of the distal end. An injection apparatus may include a hand-held injection facilitation apparatus, which may be coupled to a syringe. The hand-held injection facilitation apparatus can include a pivot arm and a body with a rod disposed within the body and coupled to the pivot arm. Movement of the pivot arm results in a proximal or distal movement of the rod within the body to effectively cause material to be expelled from the syringe. An injection apparatus may include a transition-bore needle apparatus and a hand-held injection facilitation apparatus in combination.Type: ApplicationFiled: November 14, 2003Publication date: June 3, 2004Inventor: Corbett Stone

Patent number: 6682471Abstract: An apparatus is described that efficiently resupplies radioactive seeds to a brachytherapy applicator. A seed-holding system includes a holder and a transfer device. The holder, which may be disposable, stores the radioactive seeds and the transfer device, which may be reusable, helps shield and dispense the seeds. The holder is coupled to the transfer device, and the apparatus is mated to an applicator. After seeds have been dispensed, the apparatus may be disconnected from the applicator and the empty holder may be ejected from the transfer device, and replaced with a full holder.Type: GrantFiled: October 2, 2002Date of Patent: January 27, 2004Assignee: Mentor CorporationInventors: Martin T. Steele, Sr., Scott Henderson, Joseph Harms, Charles R. Pitman

Patent number: 6616664Abstract: A clamp assembly for an external fixation system includes a first clamp member receiving a first elongated and a second clamp member receiving a second elongated member. The first clamp member includes a first fastener rotatably in a first direction to lock the first elongated member relative to the first clamp member. A second fastener connects the first and second clamp members. The second fastener is rotatable in the first direction to independently lock the second elongated member relative to the second clamp member. The first fastener is hollow and the second fastener passes through the first fastener.Type: GrantFiled: July 30, 2001Date of Patent: September 9, 2003Assignee: EBI L.P.Inventors: Stephen B. Walulik, Kirk J. Bailey

Publication number: 20030141268Abstract: The production of a protein free synthetic polyisoprene which has both low levels of chemical impurities and good physical properties has yet to be realized. It has now been envisioned that the use of neodymium catalyzed polyisoprene will offer the combined advantages of both a clean, as well as, high cis-1,4 polymer. Synthesis of polyisoprene rubber using a neodymium based catalyst system is described. Characterization of the material shows the absence of an ultra high molecular weight fraction and the presence of very high cis-1,4-microstructure. Gum stock and black filled compound studies comparing neodymium polyisoprene with natural rubber, titanium polyisoprene, and lithium polyisoprene have been performed. Results indicate that polyisoprene rubber synthesized using a neodymium catalyst. system (Nd—PI) has similar stress-strain and tear properties as synthetic titanium polyisoprene.Type: ApplicationFiled: October 18, 2002Publication date: July 31, 2003Inventors: Michael Lester Kerns, Michael Joseph Rachita

Patent number: 6592508Abstract: A method and apparatus for implanting seeds in or about a target area, such as a tumor, within a patient. The implantation device includes an implantation needle having a bore extending a longitudinally therethrough from a proximal end to a distal end of the needle, the needle bore being adapted to permit at least one seed to pass therethrough. An elongated plunger extends longitudinally through the implantation device in aligned relation to the needle bore and is selectively movable in the longitudinal direction relative the needle from a retracted position spaced apart from the needle to an extended position wherein the plunger is advanced through the needle bore to eject at least one of the seeds through the bore, out of the distal end of needle and into the target area. An optical device is carried by and operatively connected to the plunger to provide visual assistance to an operator of the implantation device to guide and verify implantation of the ejected seed into the target area.Type: GrantFiled: February 24, 2000Date of Patent: July 15, 2003Assignee: Integrated Implant Systems, LLCInventors: Steven S. Ravins, Edward Kaplan

Patent number: RE49369Abstract: A drug delivery device configured to provide a dose of medicament is disclosed. The drug delivery device includes a main housing, a syringe arranged in the main housing, and a pneumatic power pack arranged in the main housing. The pneumatic power pack includes a pressurized gas source storing pressurized gas, a valve for the pressurized gas source, a sleeve having an inner wall, and a plunger. The sleeve is configured to receive pressurized gas released from the pressurized gas source. The plunger is in sliding gas-tight engagement with the inner wall of the sleeve. Upon activation of the valve, the valve releases the pressurized gas, and the released pressurized gas flows into the sleeve and propels the plunger in a distal direction with respect to the sleeve and the syringe, so as to eject medicament from the syringe.Type: GrantFiled: November 4, 2020Date of Patent: January 17, 2023Assignee: SHL MEDICAL AGInventor: Slobodan Stefanov
