Patent number: 7384418Abstract: The invention provides devices, kits and methods for delivering an agent to a breast milk duct. Intraductal agent delivery provides an opportunity to treat a breast condition locally and avoid the pitfalls of systemic drug delivery for a local condition. Time-released agents delivered into the ducts using an intraductal device or formulation reduces the frequency of intraductal administration required for desired efficacy over time. The methods include methods of treating a breast condition, including the conditions of cancer or precancer.Type: GrantFiled: November 25, 2003Date of Patent: June 10, 2008Assignee: Cytyc CorporationInventors: David Hung, Phillip M. Olsen

Patent number: 7094215Abstract: Systems and methods are provided for performing electrosurgical interventions, such as selectively contracting soft collagen tissue and other body structures, while limiting thermal damage or molecular dissociation of such tissue and limiting the thermal damage to tissue adjacent to and underlying the treatment site. The systems and methods of the present invention are particularly useful for surgical procedures in electrically conducting environments, such as arthroscopic procedures in the joints, e.g., shoulder, knee, hip, hand, foot, elbow or the like. The present invention is also useful in relatively dry environments, such as treating and shaping the cornea, and dermatological procedures involving surface tissue contraction of tissue underlying the surface of the skin for tissue rejuvenation, wrinkle removal and the like.Type: GrantFiled: March 28, 2003Date of Patent: August 22, 2006Assignee: Arthrocare CorporationInventors: Terry S. Davison, Jean Woloszko, Phillip M. Olsen, Philip E. Eggers, Hira V. Thapliyal

Publication number: 20040153001Abstract: The invention provides methods, devices and systems for collecting breast ductal fluid comprising cellular material and other useful markers for analysis. The methods typically comprise access of at least one breast duct and collecting materials from that duct separate from all other ducts in the breast. The devices comprise ductal access devices that provide the opportunity to collect fluid from a single duct separate from all the other ducts in the breast. The systems employ the methods and devices that used together provide systems for analysis of a breast condition in a patient specific to accessed breast ducts. The methods, devices and systems are particularly useful for identification of breast precancer or cancer in within the patient.Type: ApplicationFiled: January 22, 2004Publication date: August 5, 2004Inventors: David Hung, Phillip M. Olsen, Daniel . Kurz

Patent number: 6482201Abstract: The present invention provides systems and methods for selectively applying electrical energy to a target location within or on a patient's body. In particular, methods and apparatus are provided for resecting, cutting, partially ablating, aspirating or otherwise removing tissue from a target site, and ablating the tissue in situ. The systems and methods of the present invention are particularly useful for ablation and hemostasis of tissue in sinus surgery (e.g., chronic sinusitis and/or removal of polypectomies) and for resecting and ablating soft tissue structures, such as the meniscus and synovial tissue within a joint.Type: GrantFiled: July 27, 2000Date of Patent: November 19, 2002Assignee: ArthroCare CorporationInventors: Phillip M. Olsen, Maria B. Ellsberry, David C. Hovda, Hira V. Thapliyal, Philip E. Eggers

Patent number: 6461354Abstract: Systems and methods are provided for selectively applying electrical energy to a target location on an external body surface, such as skin tissue removal and/or collagen shrinkage in the epidermis or dermis, e.g., the removal of pigmentations, vascular lesions (e.g., leg veins), scars, tattoos, etc., and for other surgical procedures on the skin, such as tissue rejuvenation, cosmetic surgery, wrinkle removal, hair removal and/or transplant procedures. The present invention applies high frequency (RF) electrical energy to one or more electrode terminals adjacent an external body surface, such as the outer surface of the skin, to remove and/or modify the structure of tissue structures within the skin. Depending on the specific cosmetic procedure, the present invention may be used to: (1) volumetrically remove tissue or hair (i.e.Type: GrantFiled: May 18, 1999Date of Patent: October 8, 2002Assignee: ArthroCare CorporationInventors: Phillip M.

Patent number: 6379351Abstract: The present invention is directed to systems, methods and apparatus for removing implanted objects from a patient's body, particularly implanted endocardial or epicardial pacemaker leads and transvenous defibrillation leads from a patient's heart. In one aspect of the invention, an electrosurgical catheter is advanced to a position within the thoracic cavity adjacent a portion of a pacemaker lead that is affixed to heart tissue. Preferably, the catheter is advanced over the pacemaker lead, i.e., using the pacemaker lead as a guidewire, to facilitate this positioning step. Once the distal end of the catheter reaches a blockage, or a portion of the lead that is attached to fibrous scar tissue, a high frequency voltage difference is applied between one or more electrode terminal(s) at the distal end of the catheter and one or more return electrode(s) to remove the scar tissue around the lead.Type: GrantFiled: February 18, 2000Date of Patent: April 30, 2002Assignee: Arthrocare CorporationInventors: Hira V. Thapliyal, Philip E. Eggers, Katherine M. Williams, Michael A. Baker, Phillip M. Olsen

Patent number: 5947958Abstract: A radiation transmitting sheath comprises a tubular body having a radiation guide extending axially therein. A coupler for attaching a radiation source is provided at the proximal end of the sheath. A dispersive tip for dispersing radiation from the radiation guide over a conical field is provided at the distal end of the sheath. Such sheaths are useful for providing illumination and endoscopic viewing methods and for providing sensitizing radiation in photodynamic therapy of body cavities.Type: GrantFiled: September 14, 1995Date of Patent: September 7, 1999Assignee: Conceptus, Inc.Inventors: Robert E.
