Abstract: Some introducer tools for bone portals have a handle coupled to a driving member by a force-limiting coupling. A bone portal comprising a bone-penetrating portion and a bone stop may be driven to a desired depth in bone when the force-limiting coupling allows application of force to the bone portal that is sufficient to drive the bone-penetrating portion of the portal into the bone but not sufficient to drive the bone stop significantly into the bone. Bone portals of various types are described herein. Various configurations for stylets suitable for use in introducing bone portals or otherwise penetrating bone and methods for inserting bone portals are also described herein.

Abstract: A pressure control apparatus for restricting a flow of blood through or from a body part includes at least one arcuate member for attaching to the body part. The at least one arcuate member has a first end and an opposite second end. The first end includes a hook for fastening to a buckle mounted at the opposite second end. A mechanical advantage power system includes a turnkey and is connected to the at least one arcuate member and serves to adjusting a pressure of the apparatus on the body part by turning the turnkey. An elongated strap is disposed on at least a circumferential portion of the arcuate member for circumferentially tightening the apparatus around the body part. A locking device closes the apparatus around the body part and is attached to the at least one arcuate member. A cover or shroud is disposed on an outer perimeter of the at least one arcuate member for enclosing a portion of the mechanical advantage power system.

Abstract: The present invention relates to a method and apparatus for locating a site of intraosseous infusion and for relieving strain and stress on the infusion site. The template patch uses a key anatomical feature of the bone as a reference point to a target zone for infusion that is located a predetermined distance away from the feature. The template patch has a tube clamp and a covering that protect the infusion site from external forces.

Abstract: A packing device made of thermo-formed plastic sheet includes a bottom plate having adjacent first recesses and each first recess has first flaps which are higher than a receiving plane of the first recess, and each first recess has a positioning portion in an inside thereof. A side plate being foldable along a folding line relative to the bottom plate has engaging portions which are engaged with the positioning portions. The side plate includes adjacent second recesses and each second recess has a plurality of second flaps which are higher than a receiving plane of the second recess. The side plate has receiving portions located opposite to the engaging portions. A top plate being foldable along a folding line relative to the side plate has protrusions which are engaged with the receiving portions when the top plate is folded the folding line toward the side plate. The top plate has third recesses and each of which has third flaps which are higher than a receiving plane of the third recess.

Abstract: This invention relates to an apparatus and method for infusing fluids to and aspirating tissue from an intraosseous site. The apparatus is comprised of an infusion tube coupled to a housing assembly with a release mechanism that removes the force exerted on the infusion tube once it has penetrated the bone a predetermined depth. As the housing assembly is withdrawn, the infusion tube remains in the bone. The ball release mechanism and other aspects of the apparatus can be modified to yield different penetration depths.

Abstract: An apparatus comprising three main assemblies, an applicator, an infusion/aspiration tube with a subcutaneous bone penetration means, and a strain relief protector. The apparatus enables a user in field or emergency environments to quickly, safely and reliably place an infusion/aspiration device in a patient's bone, regardless of the thickness of skin and tissue over the bone, and to ensure it will remain in place throughout other emergency procedures and severe environmental conditions. The infusion/aspiration apparatus incorporates a bone stop to ensure precise location of the bone penetration means at the intended marrow depth in the patient's bone.

Abstract: An intraosseous infusion device includes a base and an upper frame mounted to the base. An elongated needle is fixed to the upper frame. A fitting is provided for receiving liquid to be delivered to a patient's bone marrow and for supplying the liquid to a bore in the needle. The base includes a cam surface and the upper frame includes a cam follower. The cam surface is configured to cause the upper frame to rotate relative to the base as the needle moves longitudinally between a retracted position within the base and an extended position below the base.
