A retrieval catheter operable by a single clinician that will neither displace a deployed stent nor cause undue trauma to the vascular lumen or lesion. The retrieval catheter may be sized to accommodate both a guidewire and a balloon wire. The retrieval catheter is easy to navigate through tortuous passageways and will cross a previously deployed stent or stent-graft easily with minimal risk of snagging on the deployed stent or stent graft. The sheath and dilator are adapted to allow a guidewire or balloon wire to pass through the walls of both and to allow the sheath and dilator to move axially with respect to each other.

Retrieval catheter

A medical device which includes tubing which is partially reinforced and partially unreinforced. The device is formed by first providing tubing which is reinforced over its entire length, severing or weakening the reinforcing element, and removing an end portion of the reinforcing element. The reinforcing element can be severed or weakened using, for example, a laser. Any damage caused by the severing/weakening and/or removal of the reinforcing element can then be repaired by inserting the tubing into a heated die. An apparatus for performing the severing/weakening, removal and repair operations is also provided. The tube may be used to supply oxygen as a tracheal tube.

Method for forming a medical tubing device

A connector which includes a female part having a barrel-shaped body, with a socket extending into the female part from one end of the barrel-shaped body. The socket includes first, second, and third step portions which respectively receive a flange, a shoulder, and a stem of a male part. A lip extends radially inwardly from the barrel-shaped body of the female part, with the lip having an inner diameter smaller than the outer diameter of the flange of the male part. The male part can be inserted into the female part by inserting the flange of the male part past the lip of the female part, such that the male and female parts are snapped together. In a presently preferred embodiment, a seal ring is disposed between the male and female parts, and the seal ring is compressed in an axial direction, thereby providing the connector with a fluid tight seal.

Surgical connector

The invention is a hemostasis valve having a main body, a proximal end cap, a register member, and a reinforcing member. The main body has a proximal end, a distal end, and a first bore having a proximal end at the proximal end of the main body and a distal end at the distal end of the main body. The first bore has a first flexure-receiving enlargement at its proximal end. The proximal end cap is joined to the proximal end of the main body and forms therewith a valve chamber. The proximal end cap has a second bore formed therethrough that is at least approximately an extension of the first bore. The register member is received in the valve chamber adjacent the proximal end cap. The register member has a proximal portion and a distal portion. The proximal portion of the register member has a third bore formed therethrough that is at least approximately an extension of the first and second bores. The distal portion of the register member is flexible and contains at least one slit on the extension of the first, second, and third bores. The third bore has a second flexure-receiving enlargement adjacent its distal portion. The reinforcing member is received in the valve chamber adjacent the main body, and it has at least one slit on the extension of the first, second, and third bores.
