A system including a flow diverter for delivering bone cement. A cannula coupler is coupled to the flow diverter and configured to be coupled to a delivery cannula. A drool accumulator is coupled to the flow diverter. A user input mechanism is coupled to the flow diverter and configured to actuate a valve and establish fluid communication between the cement reservoir and one of the cannula coupler and the drool accumulator. The fluid communication may be interrupted between the cement reservoir and the other one of the cannula coupler and the drool accumulator. A cement delivery input mechanism may be coupled to the cement reservoir and configured to be actuated to direct the bone cement from the cement reservoir towards the flow diverter. An actuator may be coupled to the drool accumulator and configured to direct the bone cement received in the drool volume towards the flow diverter.

A covering for delivering a substance or material to a surgical site is provided. The covering, with substance provided therein, may be referred to as a delivery system. Generally, the covering may be a single or multi-compartment structure capable of at least partially retaining a substance provided therein until the covering is placed at a surgical site. Upon placement, the covering may facilitate transfer of the substance or surrounding materials. For example, the substance may be released (actively or passively) to the surgical site. The covering may participate in, control, or otherwise adjust the release of the substance. In various embodiments, the covering may be formed of a collagen material and is suitable for a variety of procedure specific uses.

The invention features a glenoid (shoulder socket) implant prosthesis, a humeral implant prosthesis, devices for implanting glenoid and humeral implant prostheses, and less invasive methods of their use for the treatment of an injured or damaged shoulder.

A composition delivery source (300) includes a chamber (302), a solid-liquid composition delivery tube (314), a mixing tube (316), and a liquid-supply tube (318). A filter (304) divides the chamber (302) into a liquid compartment (306) and a solid-liquid composition compartment (308). The solid-liquid composition delivery tube (314) is in fluid communication with the solid-liquid composition compartment (308). The mixing tube (316) is in fluid communication with the liquid compartment (306) and the solid-liquid composition compartment (308). The liquid-supply tube (318) is in fluid communication with the liquid compartment (306) and a liquid solution container (366). A pump unit (301) is provided that includes a mixing pump (322), which is arranged to cause flow in the mixing tube (316); and a liquid-supply pump (324), which is arranged to cause flow in the liquid-supply tube (318). Other embodiments are also described.

A method for delivering a substance to bone includes placing a stabilizing wire in a bone, creating a hole in the bone around the stabilizing wire, and providing a multichannel cannula. The multichannel cannula includes a first channel having an open proximal end and distal end, the first channel being configured to receive the stabilizing wire, and a second channel having an inlet portal and an exit portal that are in fluid communication. The cannula further includes a cap having a delivery port in fluid communication with the inlet portal and a channel for receiving the cannula therein, and a distal tip. The method further includes inserting the multichannel cannula into the hole in the bone such that the first channel receives the stabilizing wire, and delivering the substance into the bone by introducing the substance into the second channel such that the substance exits through the exit portal.

A method is provided that includes injecting, during a dental procedure, from a first side of a bone, through (a) exactly one bore that passes through the bone from the first side to a second side of the bone, and (b) into a cavity adjacent to the second side of the bone, a solid-liquid composition of solid particles and a physiological liquid solution. During the dental procedure, the physiological liquid solution is drained from the cavity and through the bore while inhibiting passage of the solid particles of the solid-liquid composition, such that the solid particles accumulate in the cavity. Injecting the solid-liquid composition includes pumping the solid-liquid composition at a pulsating positive hydraulic pressure.

An osteotome is shaped so as to define (a) a lumen through the osteotome, a distal end of the lumen opening through a distal opening disposed within 10 mm of a distal end of the osteotome, and a proximal end of the lumen opening through a proximal opening disposed at least 5 mm proximal to the distal opening, (b) a lateral external surface, at least a portion of which is shaped so as to define a screw thread that (i) has a distal thread end that is disposed within 10 mm of the distal end of the osteotome, and (ii) comprises one or more raised helical ribs going around the osteotome, and (c) one or more longitudinal drainage slots, which extend along at least respective longitudinal portions of the osteotome having respective longitudinal lengths of at least 5 mm, measured parallel to a central longitudinal axis of the osteotome.

The invention relates to a glenoid (shoulder socket) implant prosthesis, a humeral implant prosthesis, devices for implanting glenoid and humeral implant prostheses, and less invasive methods of their use for the treatment of an injured or damaged shoulder.

A method of manufacturing a resorbable balloon designed to contain bone cement for vertebroplasty or kyphoplasty applications is described. The resorbable balloon can be inserted into a vertebral body following vertebral cavitation and filled with bone cement. The balloon remains in place in the vertebral body and resorbs over time. Methods and apparatus are also described for delivering therapeutic agents using collapsible, resorbable balloons. The balloons may be nested and filled with various therapeutic agents that are released over time at rates dependent upon structures and degradation rates of the balloons. Furthermore, the function of the hollow devices can encompass both encapsulation and therapeutic substance delivery roles simultaneously.
