International Classification:

A61B 17/72

US Classification:

606 62

Abstract:

A bone fixation device is provided with an elongate body having a longitudinal axis and having a first state in which at least a portion of the body is flexible and a second state in which the body is generally rigid, an actuateable gripper disposed at one or more locations on the elongated body, a hub located on a proximal end of the elongated body, and an actuator operably connected to the gripper(s) to deploy the gripper(s) from a retracted configuration to an expanded configuration. Methods of repairing a fracture of a bone are also disclosed. One such method comprises inserting a bone fixation device into an intramedullary space of the bone to place at least a portion of an elongate body of the fixation device in a flexible state on one side of the fracture and at least a portion of a hub on another side of the fracture, and operating an actuator to deploy at least one gripper of the fixation device to engage an inner surface of the intramedullary space to anchor the fixation device to the bone. Various hub designs are disclosed that may be used in combination with other fixation device components.

International Classification:

A61M 1/00
A61M 25/00

Abstract:

A device for clearing obstructions from a medical tube includes an enclosure having an interior and an exterior, the enclosure comprising a distal opening for providing access to the interior of the enclosure. The device further includes a spool provided within the enclosure that is rotatable about an axis and an elongated guide member coupled to the spool such that rotation of the spool causes the guide member to wind or unwind about the spool. The device further includes a drive mechanism that is operable to rotate the spool within the enclosure without compromising a sterile field within the enclosure.

International Classification:

A61M 25/00
A61M 25/09

Abstract:

A device for clearing obstructions from a medical tube, such as a chest tube, is disclosed in various embodiments. In embodiments, the device features a clearance member that is formed to match a cross-section of a medical tube. Still further, the clearance member can have a plurality of branches, each branch configured to clear a respective lumen in a partitioned region of a medical tube. In this manner, the clearance member may clear obstructions from individual lumens of the partitioned region of the medical tube. Device for actuating a clearance member to clear obstructions within a medical tube are also disclosed. Methods of clearing a medical tube of obstructions are also disclosed.
