Abstract
An apparatus includes a sheath configured to be at least partially inserted into a body of a patient, the sheath having a distal end and a proximal end; a housing coupled to the proximal end of the sheath; and a control mechanism operably coupled to the housing and slidable to move the sheath relative to the housing. The control mechanism includes a locking mechanism for locking the control mechanism in place relative to the housing; a deflection mechanism for articulating a distal end of the sheath; and a saddle slidable relative to the locking mechanism and the deflection mechanism. A device is coupled to the saddle and is extendable from and retractable within the sheath.
Claims18
An apparatus, comprising:
- a sheath configured to be at least partially inserted into a body of a patient, the sheath having a distal end and a proximal end;
- a housing coupled to the proximal end of the sheath;
- and
- a control mechanism operably coupled to the housing and slidable to move the sheath relative to the housing, the control mechanism comprising:
- a locking mechanism for locking the control mechanism in place relative to the housing;
- a deflection mechanism for articulating a distal end of the sheath;
- and
- a saddle slidable relative to the locking mechanism and the deflection mechanism;
- wherein a device is coupled to the saddle and is extendable from and retractable within the sheath.
A medical, device for positioning a catheter having an expandable element, the medical device comprising:
- a handle having a control section slidable on the handle;
- a saddle slidable on the control section;
- and
- a steerable sheath coupled to the handle, the steerable sheath being configured to be inserted into a body of a patient and movable relative to the handle by sliding the control section;
- the control section comprising,
- a locking stopper to lock the control section in place on the handle, and
- an adjustment control to deflect a distal end of the steerable sheath;
- wherein the catheter is positioned into the body of the patient by sliding movement of the saddle to move the catheter out of the steerable sheath.
A controlling assembly for a medical device having a handle and a steerable sheath coupled to the handle, the controlling assembly being slidable on the handle to extend the steerable sheath from the handle, the controlling assembly comprising:
- a locking mechanism to lock the controlling assembly to the handle;
- and
- a deflection control mechanism connected to a distal end of the steerable sheath to control movement of the steerable sheath.
