Publication number: 20220401108Abstract: A device for compressing body tissue includes a clip having a connection portion with first and second clip arms extending therefrom, the clip includes a recess formed on an inner surface of the connection portion, the recess being shaped and sized to slidably receive a mounting bar coupled to an outer surface of an endoscope on which the mounting bar is mounted with inner surfaces of the first and second clip arms maintained in an open position by contact between an endoscope on which the mounting bar is mounted and the inner surfaces of the first and second clip arms. The clip is slidable over the outer surface of an endoscope on which the mounting bar is mounted until the clip moves distally beyond the distal end of the endoscope so that the first and second clip arms spring closed to grip tissue therebetween.Type: ApplicationFiled: August 25, 2022Publication date: December 22, 2022Inventor: Douglas C.

Publication number: 20160249889Abstract: A needle for collecting a tissue samples includes a needle body extending along a longitudinal axis from a proximal end to a distal end including a sharp tip for penetrating a target tissue. The needle body includes a channel extending therethrough for collecting a tissue sample therein when the distal end is inserted into the target tissue. A distal portion of the needle body has a first stiffness and a proximal portion of the body has a second stiffness of the proximal portion less than the first stiffness. The needle also includes a sleeve extending along a length of the needle body to cover the pattern along the proximal portion.Type: ApplicationFiled: February 3, 2016Publication date: September 1, 2016Inventors: Peter L.

Publication number: 20030203000Abstract: A method of modulating a rate of release of a therapeutic agent from a medical device is provided. The method comprises: (a) providing a solution comprising a therapeutic agent, a polymer and a solvent system; and (b) forming a therapeutic-agent-loaded polymeric carrier for the medical device by evaporating the solvent system, such that the rate of release is modulated by changing the composition of the solvent system. The composition of the solvent system can be changed in a number ways, including adding solvent species to the solvent system, removing solvent species from the solvent system, both adding and removing solvent species from the solvent system. The solvent system can also be changed by varying the ratio of solvent species within the solvent system.Type: ApplicationFiled: April 24, 2002Publication date: October 30, 2003Inventors: Marlene C.
