Patent number: 7073504Abstract: A device and method of using the device for contraception or sterilization and particularly for reversible contraception by occluding a reproductive lumen to prevent the passage of reproductive cells through the lumen for a desired period of time until the patient wishes to become fertile again and then be reopened. The occluding member preferably comprises a tubular framework formed from a shape memory material configured to be implanted in a reproductive lumen. The occluding member is implanted within a body lumen, secured to the wall of the reproductive lumen and then collapsed to collapse the wall and occlude the lumen. Alternatively, the occluding member may be collapsed upon a solid plug. The closure of the reproductive lumen may be reversed by introducing a balloon catheter and by a series of inflations of the balloon reexpanding the collapsed occluding member or by removing the plug.Type: GrantFiled: December 18, 1996Date of Patent: July 11, 2006Assignee: AMS Research CorporationInventors: Jeffrey P.

Patent number: 7069929Abstract: A dry powder inhaler includes an actuator pivotably mounted on a base. Movement of the actuator from a first position to a second position drives the a dobber to open a blister. A dispersion engine sub-assembly has a blister hood positioned over a blister opening position. A powder pathway connects from the blister hood into a powder dispersion engine. Upon inhalation, air flow draws powder up and out of an opened blister, into the blister hood and to the powder dispersion engine. Movement of the actuator causes the dobber to shear open a blister and also to press the blister hood down over the blister. This increases air flows up and around the open blister, carrying the pharmaceutical powder up and out of the blister and into the dispersion engine.Type: GrantFiled: March 15, 2002Date of Patent: July 4, 2006Assignee: Quadrant Technologies LimitedInventors: Matthew Young, Stuart Kay, Neil Harrison, James Welsh, Michael Ligotke

Patent number: 7070607Abstract: A new embolic agent, bioabsorbable polymeric material (BPM) is incorporated to a Guglielmi detachable coil (GDC) to improve long-term anatomic results in the endovascular treatment of intracranial aneurysms. The embolic agent, comprised at least in part of at least one biocompatible and bioabsorbable polymer and growth factors, is carried by hybrid bioactive coils and is used to accelerate histopathologic transformation of unorganized clot into fibrous connective tissue in experimental aneurysms. An endovascular cellular manipulation and inflammatory response are elicited from implantation in a vascular compartment or any intraluminal location. Thrombogenicity of the biocompatible and bioabsorbable polymer is controlled by the composition of the polymer. The coil further is comprised at least in part of a growth factor or more particularly a vascular endothelial growth factor, a basic fibroblast growth factor or other growth factors.Type: GrantFiled: February 16, 2001Date of Patent: July 4, 2006Assignee: The Regents of the University of CaliforniaInventors: Yuichi Murayama, Fernando Vinuela

Patent number: 6986786Abstract: The prostheses include an endovascular member in need of repair and a patch therefore, as well as prostheses including two or more endovascular members, such as stent-grafts, which may be assembled in situ. Components of the prostheses are held together in substantially fluid tight engagement as the result of hook and loop structures which are present on the members. The hooks engage the loops to secure the components to one another. As a result, the present invention is particularly useful for the in situ repair of damaged prostheses and for the in situ assembly of bifurcated endovascular prostheses, particularly for the treatment of abdominal aortic aneurysms.Type: GrantFiled: September 11, 2000Date of Patent: January 17, 2006Assignee: SCIMED Life Systerms, Inc.Inventor: John K.

Patent number: 6983750Abstract: A method of determining ventilation inhomogeneity in the lungs is provided. During the first step of the method, a lung volume series is calculated from a series of measured lung inert gas concentrations and lung inert gas volumetric change measured data series. As a second step, the series of lung volumes is completed with a series of value representing the total gas exchange efficiency in the lungs. A global inert gas dilution ratio may be used for this purpose. The gas exchange efficiency values are such that less ventilation is represented by lower numbers. As the third step, the gas exchange efficiency series is plotted as an ordinate and lung volume series as an abscissa to form a graph. From this graph both the lung volume and homogeneity of ventilation become directly apparent.Type: GrantFiled: August 26, 2003Date of Patent: January 10, 2006Assignee: Instrumentarium Corp.Inventor: Erkki Heinonen
