Abstract

The invention relates to a integrated guidewire needle knife device. Devices and methods for translumenal access are also provided. In one embodiment, a device for translumenal access includes an elongate member having proximal and distal ends and a lumen extending therethrough. A tissue-penetrating wire can extend through the lumen, and in use the wire can be selectively movable between a retracted position where the wire is in a constrained configuration within the lumen and an extended position in which a portion of the wire extends a distance beyond a distal end of the elongate member. The portion of wire which extends the distance beyond the distal end of the elongate member can be adapted to assume a non-linear unconstrained configuration to prevent injury to the tissue and / or tissue structures adjacent to the tissue.

Description

technical field [0001] The present invention relates to surgical devices, and in particular to devices for use in transluminal procedures. Background technique [0002] Laparoscopic surgery is a minimally invasive surgical procedure in which the surgeon uses multiple trocar holes to access and visualize relevant tissue sites within the abdominal cavity of a patient under general anesthesia. Advantages of laparoscopic surgery include less pain, shorter recovery time, less scarring, and lower cost compared to open abdominal surgery. Yet another method of accessing the abdominal cavity is through the body's natural openings (mouth, anus, vagina, urethra) and through the peritoneal skin of the abdominal cavity. Obviously, the size and shape of instruments that can be passed through a body cavity in order to perform a medical procedure in the abdominal cavity is very limited due to the anatomical nature of the body cavity. [0003] General surgeons, gastroenterologists, and oth...
