Abstract

A suture trimmer having a shaft with a groove formed in the side thereof, a cutting member movably disposed within the shaft, and a suture retainer slidably disposed within the shaft. The suture trimmer may be used to position knots formed within a suture loop prior to trimming the free end(s) of the suture loop, and to deliver an agent near the location where the suture is severed.

Independent Claims | See all claims (21)

  1. 1. A medical device suitable for delivering an agent to a subcutaneous location in a patient body, the medical device comprising: a handle having a proximal end and a distal end; an elongate member extending from the distal end of the handle; a sliding member within the elongate member, the sliding member defining a first lumen; and a biasing member, comprising a flexible tube, wherein the flexible tube comprises a wall defining an agent delivery lumen and wherein the flexible tube further includes a stiffening member formed of a pre-bent wire, operatively associated with the sliding member to provide a biasing force on the sliding member, the biasing member defining a second lumen in fluid communication with the first lumen.
  2. 8. A medical device comprising: a handle having a proximal end and a distal end; an elongate member extending from the distal end of the handle; a suture retainer slidably disposed within the elongate member, the suture retainer defining a first lumen; and a biasing member comprised of a flexible tube having a wall defining an agent delivery lumen and wherein the flexible tube further includes a stiffening member, operatively associated with the suture retainer to provide a biasing force on the suture retainer, the a biasing member defining a second lumen in fluid communication with the first lumen.
  3. 16. A method comprising: providing a medical device comprising a handle having a proximal end and a distal end; an elongate member extending from the distal end of the handle, the elongate member defining an opening for accepting a suture; a suture retainer slidably disposed within the elongate member, the suture retainer defining a first lumen; a biasing member operatively associated with the suture retainer to provide a biasing force on the suture retainer, the biasing member defining a second lumen in fluid communication with the first lumen; and an inlet port on the proximal end of the handle, the inlet port being in fluid communication with the first lumen and the second lumen; connecting an agent carrying vessel to the inlet port; and moving an agent from the agent carrying vessel through the inlet port and further through the first lumen and the second lumen.
  4. 19. A medical device suitable for delivering an agent to a subcutaneous location in a patient body, the medical device comprising: a handle having a proximal end and a distal end; an elongate member extending from the distal end of the handle; an agent cartridge configured to be received within a portion of the handle, the agent cartridge in fluid communication with a lumen of the elongated member; a sliding member within the elongate member, the sliding member defining a first lumen; and a biasing member operatively associated with the sliding member to provide a biasing force on the sliding member, the biasing member defining a second lumen in fluid communication with the first lumen.
