Publication number: 20130018366Abstract: A focal ablation assembly, used with an endoscope comprising an endoscopic tube, comprises a cap and a cryogenic catheter placeable within the endoscopic tube channel. The cryogenic catheter defines a catheter lumen and has a distal end placeable at the endoscopic tube distal end. The cap is mountable to at least one of the distal ends and extends distally of both. The cap comprises a material which substantially maintains its shape during use while not causing tissue trauma. The cap defines a limited area therapeutic region, which is a chosen one of an open therapeutic region and a covered, effectively thermally transparent therapeutic region providing effectively no thermal insulation. In some examples the assembly includes a delivery catheter extending along the channel with a distal portion fluidly coupled to the cap volume, whereby refrigerant can be introduced into the cap volume and towards the therapeutic region by the delivery catheter.Type: ApplicationFiled: July 11, 2011Publication date: January 17, 2013Applicant: C2 TherapeuticsInventors: Patrick P.

Patent number: 8187327Abstract: An apparatus includes a scaffold configured to be disposed in a bone. The scaffold is configured to move from a first configuration to a second configuration. The scaffold in the second configuration is expanded from the first configuration. A selectively-expandable actuator is configured to be removably disposed within the scaffold. The selectively-expandable actuator is configured to move at least a portion of the scaffold to the second configuration when the selectively-expandable actuator is moved to an expanded configuration. A shape of the selectively-expandable actuator is substantially the same as a shape of the scaffold when the selectively-expandable actuator and the scaffold are in the second configuration. The selectively-expandable actuator configured to be removed from the scaffold when in a collapsed configuration. The scaffold is configured to remain substantially in the second configuration after the scaffold has been expanded by the actuator.Type: GrantFiled: May 18, 2005Date of Patent: May 29, 2012Assignee: Kyphon SARLInventors: Avram Allan Edidin, Arthur E.

DEVICES AND METHODS USING AN EXPANDABLE BODY WITH INTERNAL RESTRAINT FOR COMPRESSING CANCELLOUS BONE
Publication number: 20110144688Abstract: Devices and methods compress cancellous bone. In one arrangement, the devices and methods make use of an expandable body that includes an internal restraint coupled to the body. The internal restraint directs expansion of the body. In one arrangement, a method for treating bone inserts the device having the internal restraint inside bone and causes directed expansion of the body in cancellous bone. Cancellous bone is compacted by the directed expansion.Type: ApplicationFiled: January 7, 2011Publication date: June 16, 2011Applicant: KYPHON SÀRLInventors: Paul Reiss, Cesar Ico, Karen D.

Publication number: 20070299455Abstract: A balloon for use in compressing cancellous bone and marrow (also known as medullary bone or trabecular bone). The balloon comprises an inflatable balloon body for insertion into said bone. The body has a shape and size to compress at least a portion of the cancellous bone to form a cavity in the cancellous bone and/or to restore the original position of the outer cortical bone, if fractured or collapsed. The balloon desirably incorporates restraints which inhibit the balloon from applying excessive pressure to various regions of the cortical bone. The wall or walls of the balloon are such that proper inflation of the balloon body is achieved to provide for optimum compression of the bone marrow. The balloon can be inserted quickly into a bone. The balloon can be made to have a suction catheter. The balloon can be used to form and/or enlarge a cavity or passage in a bone, especially in, but not limited to, vertebral bodies.Type: ApplicationFiled: August 28, 2007Publication date: December 27, 2007Inventors: Sheila Stevens, Ryan Boucher, Lulu Follmer, Nenita Salom, Paul Reiss, Cesar Ico, Karen Talmadge, Mark Reiley, Arie Scholten
