Abstract
Expandable prosthetic devices used for treating a variety of conditions, including rotator cuff injuries, broken and/or depressed bone fractures, infection and/or inflammation in the body. In one embodiment, a prosthesis includes an implant having a pressure regulating valve. The implant is capable of being positioned between a first tissue and an opposing second tissue in a void space and of deforming under pressure in response to articulation of a joint. The pressure regulating valve is configured to open based on a predetermined pressure in the implant.
Claims20
A surgical system, comprising:
- an inflatable implant;
- and
- a surgical instrument that is manipulatable and actuatable as a single instrument, the instrument including:
- a handle;
- a shaft extending distally from the handle;
- a sheath positioned about at least a portion of the shaft, the sheath coupled with and movable relative to the shaft to selectively maintain the inflatable implant in a collapsed position, the inflatable implant releasably secured to a distal end of the shaft;
- a fluid passage extending through at least a portion of the handle and the shaft;
- and
- a user-engageable mechanism on the handle configured to release the inflatable implant from the distal end of the shaft.
A method of implanting an inflatable implant within an anatomy of a patient, comprising:
- obtaining the inflatable implant positioned on a distal end of a shaft of a surgical instrument, the shaft extending proximally to a proximal handle including a user-engageable mechanism to selectively secure or release the implant, the surgical instrument further including a fluid passage extending through at least a portion of the shaft and in fluid communication with the implant, and a sheath coupled to and movable about at least a portion of the shaft, the sheath movable relative to the shaft between a first configuration and a second configuration, where in the first configuration the sheath maintains the inflatable implant in a collapsed position and the sheath and the inflatable implant are insertable into a space of a joint, and in the second configuration the sheath is positioned toward a proximal end of the shaft and at least a portion of the inflatable implant is outside of the sheath;
- inserting the distal end of the shaft, the sheath, and the inflatable implant into the patient and relative to the anatomy in the first configuration;
- withdrawing the sheath from the first configuration to the second configuration;
- inflating the implant by passing an inflation material through the fluid passage and into the implant;
- and
- actuating the user-engageable mechanism to release the implant from the shaft.
A surgical system, comprising:
- an inflatable implant;
- and
- a surgical instrument, including:
- a handle;
- a shaft extending distally from the handle;
- a sheath positioned about at least a portion of the shaft, the sheath coupled with and movable relative to the shaft to selectively maintain the inflatable implant in a collapsed position, the inflatable implant releasably secured to a distal end of the shaft;
- a fluid passage extending through at least a portion of the handle and the shaft;
- and
- a user-engageable mechanism coupled with the handle, the user-engageable mechanism actuatable between a first position to maintain the implant at the distal end of the shaft and a second position to release the inflatable implant from the distal end of the shaft.
