Patent number: 6026809Abstract: An inhaler that utilizes vibration to facilitate suspension of powder into a gas is provided. One embodiment of the inhaler includes a piezoelectric vibrator for vibrating the powder. A controller is provided for controlling supply of actuating electricity to the vibrator so as to cause the powder to vibrate in such a way as to optimally suspend at least a portion of the powder into the gas. The controller may include a user-actuable control for permitting the user to select the vibration frequencies and/or amplitudes for optimally suspending in the gas the type of powder currently being used in the inhaler.Type: GrantFiled: January 25, 1996Date of Patent: February 22, 2000Assignee: Microdose Technologies, Inc.Inventors: Andrew L. Abrams, Anand V. Gumaste

Patent number: 5960609Abstract: Electrostatic phototechnology is used to package microgram quantities of fine powders such as drugs in discrete capsule and tablet form. An electrostatic "image" having a given size and charge density is exposed to ionized drug powder to attract a known amount of drug to the image. The resultant drug "image", is then transferred to a an open ended capsule, a partially formed tablet or edible wafer or belt. The capsule is then sealed, i.e. by capping, or the tablet finished.Type: GrantFiled: June 12, 1998Date of Patent: October 5, 1999Assignee: Microdose Technologies, Inc.Inventors: Andrew L. Abrams, Anand V. Gumaste

Patent number: 5840062Abstract: An apparatus and method are disclosed that utilize piezoelectric materials as part of a delivery system capable of the rapidly repetitive dispensing of a fluid to an intended target site. In a particular embodiment, the appartus contemplates a solid state needleless injection system which comprises a first housing structure having a dispensing chamber of variable volume capacity and at least one nozzle element for fluid discharge, and a fluid reservoir operatively connected to the first housing structure, and a second housing structure containing at least one piezoelectric actuator. A valve means is disposed between the fluid reservoir and the dispensing chamber to control the flow of said fluid therebetween. The fluid which may be a medication, is forced out of the dispensing chamber through an injection port upon actuation of the piezoelectric actuator.Type: GrantFiled: November 8, 1995Date of Patent: November 24, 1998Inventors: Anand V. Gumaste, Andrew L. Abrams, Scott Fleming

Patent number: 5694920Abstract: An inhaler includes a vibrator to deaggregated medication in powder form. One embodiment of the inhaler includes a piezoelectric vibrator 54 for vibrating a diaphragm for imparting vibration to a powder, and a controller 70 for controlling vibration so as to optimally suspend at least a portion of said powder in a fluidized state. An electrostatic charge plate 32 draws powder of selected particle size into the inhalation stream.Type: GrantFiled: January 24, 1997Date of Patent: December 9, 1997Inventors: Andrew L.

Patent number: 5693016Abstract: An apparatus and method are disclosed that utilize piezoelectric materials as part of a delivery system capable of the rapidly repetitive dispensing of a fluid to an intended target site. In a particular embodiment, the apparatus contemplates a needleless injection system which comprises a second housing structure, a plurality of piezoelectric elements which are stacked in a layered fashion within the second housing structure, electronic circuitry disposed proximate the second housing structure and hence the layered stack of piezoelectric elements, and a first housing structure containing a fluid reservoir operatively connected to the second housing structure so as to allow fluid contained with the fluid reservoir to communicate with the layered stack of piezoelectric elements. The layered stack of piezoelectric elements has at least one common aperture formed therein which extends therethrough.Type: GrantFiled: November 8, 1995Date of Patent: December 2, 1997Inventors: Anand V.

Patent number: 5490763Abstract: A centrifugal pump for shear sensitive fluids includes a pump housing defining an interior volume. An impeller comprising at least two vanes is rotatably mounted in the housing. The impeller vanes, which preferably are airfoil-shaped, are spaced from the interior housing of the pump whereby to leave a gap between the vanes and the pump housing so as to permit a portion of the fluid in the spacing to flow smoothly over the top contour of the impeller vanes.Type: GrantFiled: September 15, 1994Date of Patent: February 13, 1996Inventors: Andrew L. Abrams, Christopher M. Gaylo

Patent number: 5472447Abstract: A power-assisted obturator system for penetrating a body cavity wall is provided. The system comprises an obturator having main shank with a tip on its distal end. The tip has relatively blunt dull cutting edges which are incapable of readily cutting through bodily tissue except when the tip is vibrated at ultrasonic or near-ultrasonic frequencies. The proximal end of the main shank is connectable to an ultrasonic power source, which provides power to vibrate the obturator tip at ultrasonic or near-ultrasonic frequencies thereby transforming the relatively blunt edges into cutting edges which simultaneously cut and coagulate tissue. In a preferred embodiment, the obturator system includes vibration feedback and control which terminates delivery of energy to the tip when penetration is sensed.Type: GrantFiled: May 3, 1994Date of Patent: December 5, 1995Inventors: Andrew L. Abrams, Christopher M. Gaylo
