【発明の名称】円周方向リード係止装置を備えた縫合スリーブ
Document Type and Number:
Japanese Patent JP2001510362
Kind Code:
A
Abstract:
A suture sleeve for facilitating the ligature of an implanted catheter or lead to a patient's vein or underlying tissue having a longitudinal sleeve throughbore for receiving the lead body extending through a sleeve body and a movable locking member manually actuable between a locked and an unlocked position. The throughbore of the movable locking member is aligned with throughbores of the sleeve body, and the movable locking member and transverse channel are shaped to bias the movable locking member to the unlocked position. The locking member is movable laterally in a locking direction in a transverse channel extending laterally across the sleeve body with respect to the sleeve throughbore to a locked position that diminishes the movable locking member throughbore thereby compressing the lead body and applying a relatively uniform pressure in a band extending around its circumference, thereby minimizing lead body shear stresses. The locked position is maintained by engagement of mating fixed locking detents on the sleeve body and movable locking detents on the movable locking member. The locking member is unlocked by applying release force, preferably through the jaws of a forceps, against fixed rails on one side of the sleeve body transverse channel and against movable rails on the side of the locking member extending through the transverse channel on the other side of the sleeve body to release the locking detents and allow the locking member to move laterally in the channel to the unlocked position. When the locking member is in both the locked and the unlocked positions, the locking member throughbore is in substantial coaxial alignment with the longitudinal throughbores in the sleeve body, which are elongated in the transverse channel direction, thereby minimizing bending of the lead body in either position.
