摘要:
A system for supporting a breathing passage of a patient may include a cannula and an insertion apparatus. The cannula may be configured to be at least partially inserted into a breathing passage of a patient for supporting the breathing passage during sleep. The cannula may include an insertion end configured to be inserted through a nasal passageway portion of the breathing passage. The insertion apparatus may include a nasal applicator operable to guide the cannula through the nasal applicator and into the nasal passageway, and a support frame coupled to the nasal applicator and configured to be releasably coupled to the patient to position the nasal applicator proximate to the nasal passageway.

Apparatus and method for harvesting selected vessels in the body of a patient include manual manipulation of a rigid dissecting endoscope and the reconfiguration thereof to facilitate tissue dissection and tissue dilation in the formation of an anatomical space about the vessel within which side-branch vessels may be manipulated in preparation for severance and removal of the vessel from the anatomical space.

Methods and devices which a surgeon may use to stabilize the beating heart during a surgical procedure on the heart. A stabilizing device may be introduced through an opening in the chest and brought into contact with the beating heart. By contacting the heart with the device and by exerting a stabilizing force on the device, the motion of the heart caused by the contraction of the heart muscles in a vicinity of a site of surgery to be performed, is effectively eliminated. A surgeon may contact the heart with the stabilizing means, assess the degree of movement of the anastomosis site, and exert a force on the stabilizing means such that the contraction of the beating heart causes only minimal excess motion at the surgery site. The stabilizing means may be attached to a rigid support or may be attached to a semi-rigid support which is rendered motionless mechanically, chemically, or by human intervention.
摘要:
The invention is methods and devices which a surgeon may use to stabilize the beating heart during a surgical procedure on the heart. Pursuant to the invention, a stabilizing device is introduced through an opening in the chest and brought into contact with the beating heart. By contacting the heart with the device and by exerting a stabilizing force on the device, the motion of the heart caused by the contraction of the heart muscles is effectively eliminated such that the heart is stabilized and the site of the surgery moves only minimally if at all. Typically, in separate steps, the surgeon contacts the heart with the stabilizing means, assesses the degree of movement of the anastomosis site, and exerts a force on the stabilizing means such that the contraction of the beating heart causes orgy minimal excess motion at the surgery site. By fixing the position of the stabilizing means in a configuration where the motion of the beating heart is effectively eliminated, the surgeon is able to stabilize the beating heart for the duration of the procedure. The stabilizing means may be attached to a rigid support or may be attached to a semi-rigid support which is rendered motionless mechanically, chemically, or by human intervention. In certain preferred embodiments, the stabilizing means is affixed to a semi-rigid support which is caused to become rigid, by any of a variety of techniques, such that the position of the stabilizing means becomes fixed by the support, and the heart remains substantially motionless for the duration of the procedure.
摘要:
A system for preparing a graft vessel for anastomosis includes one or more tools held within a functional package having at least one recess. An anastomosis tool or portion thereof may be held in at least one recess. An anastomosis device is connected to the anastomosis tool. At least one recess is shaped and sized to hold an amount of biocompatible fluid sufficient to immerse the anastomosis device.

A system for preparing a graft vessel for anastomosis includes one or more tools held within a functional package. The package has multiple recesses and can be sealed and sterilized along with its contents. The recesses are used to hold one or more tools for preparing a graft vessel for anastomosis. Additionally, the package includes one or more recesses or other features molded into it that allow for storing a graft vessel in a biocompatible fluid such as blood or saline solution, for moving one or more tools relative to one another, or for performing other functions.
