The fat tissue sampling, collection and processing device includes a suction plate, mounted within a collection chamber, and having multiple hollow projections for supporting the open proximal ends of a plurality of tissue collection and processing tubes, wherein each tissue collection and processing tube has micro-pores formed in the side walls thereof, and its distal end opening is capped. Aspirated fat tissue is collected in a selected tissue collection and processing tube, while allowing fluid to flow and filter through the micro-pores as aspirated fat tissue flows through the cannula of the fat aspiration instrument.Type: ApplicationFiled: December 8, 2011Publication date: November 1, 2012Inventor: Robert L. Cucin

Patent number: 8287466Abstract: A biopsy device and method are provided for obtaining a tissue sample, such as a breast tissue biopsy sample. The biopsy device may include an outer cannula having a distal piercing tip, a cutter lumen, a side tissue port communicating with the cutter lumen, and at least one fluid passageway disposed distally of the side tissue port. The inner cutter may be advanced in the cutter lumen past the side tissue port to sever a tissue sample. After the tissue sample is severed, and before the inner cutter is retracted proximally of the side tissue port, the cutter may be used to alternately cover and uncover the fluid passageway disposed distally of the side tissue.Type: GrantFiled: February 26, 2010Date of Patent: October 16, 2012Assignee: Devicor Medical Products, Inc.Inventors: Robert F. Weikel, Jr., Lee E. Reichel, John A. Hibner, Michael R. Ludzack

Patent number: 8282575Abstract: An endoscopic puncture needle includes a sheath, an outer needle, an outer needle moving member, an inner needle, an inner needle moving member, and an operation portion. The outer needle moves along an axial direction of the sheath in the sheath, and is retractable with respect to a distal end of the sheath. The outer needle moving member is arranged at a proximal end portion of the outer needle, and moves the outer needle with respect to the sheath. The inner needle moves in the outer needle along the axial direction of the sheath, and is retractable with respect to a distal end of the outer needle. The inner needle moving member is arranged at a proximal end portion of the inner needle, and moves the inner needle with respect to the outer needle. The operation portion operates the outer needle moving member and the inner needle moving member.Type: GrantFiled: January 14, 2008Date of Patent: October 9, 2012Assignee: Olympus Medical Systems Corp.Inventors: Masatoshi Tonomura, Teruhisa Seki

Publication number: 20120253226Abstract: A biopsy device comprises a probe and a holster. The probe has a distally extending needle including a transverse tissue receiving aperture. A cutter is translatable relative to the needle to sever tissue protruding through the aperture. A thumbwheel is manually operable to rotate the needle to reorient the angular position of the aperture about the longitudinal axis defined by the needle. The thumbwheel is positioned obliquely with the longitudinal axis. A cable driven mechanism in the holster drives the cutter. A rotatable tissue sample holder is coupled with the probe, and has chambers configured to receive tissue samples communicated proximally through a lumen defined by the cutter. A piezoelectric motor in the holster drives the tissue sample holder.Type: ApplicationFiled: June 18, 2012Publication date: October 4, 2012Applicant: Devicor Medical Products, Inc.Inventors: Shailendra K. Parihar, John A. Hibner, Andrew P. Nock, Wells D. Haberstich, Gregory W. Johnson, Jessica P. Leimbach, Michael R. Ludzack

Publication number: 20120253225Abstract: An aspiration apparatus includes a barrel having a needle receiving end and a piston receiving end. The barrel has an inner diameter and an outer diameter. The piston receiving end of the barrel has substantially the same inner diameter as the inner diameter of the barrel. The barrel has an opening therein through a sidewall of the barrel. The opening is between the needle receiving end and the piston receiving end. The opening is distant from the needle receiving end. The aspiration apparatus also includes a needle sealingly attached to the needle receiving end of the barrel, and a piston having an end which substantially seals to the inner diameter of the barrel. The piston is capable of a number of positions including a first position near the needle receiving end, a third position past the opening in the barrel.Type: ApplicationFiled: March 29, 2012Publication date: October 4, 2012Inventors: Zine-Eddine Boutaghou, Peter Crane

Patent number: 8277393Abstract: A disposable tissue removal device comprising a cutting element mounted to a handpiece. The cutting element includes an outer cannula defining a tissue-receiving opening and an inner cannula concentrically disposed within the outer cannula. The outer cannula has a trocar tip at its distal end and a cutting board snugly disposed within the outer cannula. The inner cannula defines an inner lumen that extends the length of the inner cannula and terminates in an inwardly beveled, razor-sharp cutting edge. The inner cannula is driven by both a rotary motor and a reciprocating motor. At the end of its stroke, the inner cannula makes contact with the cutting board to completely sever the tissue. An aspiration vacuum is applied to the inner lumen to aspirate excised tissue through the inner cannula and into a collection trap that is removably mounted to the handpiece. The rotary and reciprocating motors are hydraulically powered through a hydraulic circuit.Type: GrantFiled: May 18, 2004Date of Patent: October 2, 2012Assignee: Suros Surgical Systems, Inc.Inventors: Michael E. Miller, Joseph L. Mark, Charles Butcher, John Phillip Hancock
