Patent number: 8323215Abstract: During use there is a risk that a male connector for a guide wire is bent. With the present male connector (1) more material with high modulus of elasticity can be provided inside the male connector (1), which makes the male connector (1) more bending resistant. The male connector (1) comprises a core wire (3), a plurality of conductive members (4) spaced apart longitudinally along said core wire (3), a plurality of conductors (5) disposed along the core wire (3), each of the conductors (5) being connected to a respective conductive member (4). The core wire (3) has such a shape that least one longitudinal cavity is provided, which longitudinal cavity remains substantially intact when the male connector (1) is bent, thereby protecting the conductors (5), which are disposed in said cavity, from being damaged.Type: GrantFiled: April 21, 2005Date of Patent: December 4, 2012Assignee: Radi Medical Systems ABInventors: Pär von Malmborg, Ola Hammarström, Pär Gustafsson

Patent number: 6517481Abstract: The sensor and guide wire assembly having a sensor element is inserted into the patient's body. Acoustic or electromagnetic waves are them emitted from an external source toward the sensor element. The sensor element receives the incident waves and enters into a resonating state. The characteristics of the resonance correspond to the variable or variables to be measured. A transducer is located externally from the patient's body and receives the scattered wave and transmits a resultant signal to an electronic drive and detection unit for signal analysis.Type: GrantFiled: September 12, 2001Date of Patent: February 11, 2003Assignee: Radi Medical Systems ABInventors: Bertil Hoek, Ola Hammarstroem, Per Benkowski, Paer von Malmborg, Lars Tenerz

Patent number: 6336906Abstract: A sensor and guide wire assembly includes a core wire having a distal end, a proximal end, and a plurality of sections of different cross sections and thereby different flexibilities. At least one of the core wire sections has an enlarged portion with a sensor receptacle therein. The assembly also includes a tube that encloses the core wire over at least a fraction of its length such that the core wire extends out from a distal end of the tube. The tube is configured to enable the sensor and guide wire assembly to be inserted into an artery and to be passed to a measurement site inside a patient's body. The assembly further includes a sensor mounted in the sensor receptacle of the enlarged portion of the core wire. A first coil is arranged to enclose a first portion of the core wire extending out from the distal end of the tube, and the first coil is located nearer to the proximal end of the core wire than the sensor.Type: GrantFiled: September 15, 2000Date of Patent: January 8, 2002Assignee: Radi Medical Systems ABInventors: Ola Hammarström, Per Benkowski, Pär von Malmborg, Lars Tenerz

Patent number: 6196980Abstract: A male connector with a continuous surface is provided for a guide wire. The male connector includes a core wire (1), and conductive members (5) spaced apart longitudinally along the core wire (1). An insulating material (9) is disposed between the core wire (1) and the conductive members (5), the insulating material having an outer surface coextensive with outer surfaces of the conductive members (5). Conductors (7), disposed along the core wire (1), are connected to the conductive members (5). The outer surface of the insulating material and the outer surfaces of the conductive members (5) are substantially smooth.Type: GrantFiled: June 15, 1999Date of Patent: March 6, 2001Assignee: Radi Medical System ABInventors: Dan Akerfeldt, Peter Jensen, Ola Hammarstroem

Patent number: 6167763Abstract: The invention relates to a sensor/guide wire device for biological pressure measurements having a guide wire (16, 17, 18, 21, 23) having a distal and a proximal end, and a pressure sensor device (19) mounted at the distal end of the guide wire. The distal portion can be a solid wire member (16) surrounded by a spiral member (18), and the sensor (19) can be an electrical sensor of a piezoresistive type. The sensor (19) is mounted on the solid wire (16). The sensor is mounted in a cantilevering fashion such that a pressure sensitive end of the sensor does not contact any structure other than its mount. This prevents forces (bending artifacts) from being exerted on the sensor, which could otherwise interfere with pressure measurements.Type: GrantFiled: April 12, 2000Date of Patent: January 2, 2001Assignee: Radi Medical Systems ABInventors: Lars Tenerz, Ola Hammarström, Leif Smith
