Hand-held vein removal device
First Claim
1. A vein removal device, comprising:
- a housing longitudinally extending from a first end portion to a second end portion;
a blade element, including a cutting edge, disposed at least partially within the first end portion of the housing;
a hook element disposed at the second end portion of the housing; and
a first user input device, operably coupled to the blade element, actuatable from and between a resting position and a depressed position along angular direction relative to the extension of the housing,wherein actuation of the first user input device from the resting position toward the depressed position causes the blade element to move relative to the housing from a retracted position within the first end portion to an extension position in which the cutting edge is selectively exposed a distance that is proportionate to an amount of actuation of the first user input device.

Abstract
A vein removal device includes a housing, a blade element disposed at least partially within the housing, and a hook element disposed at least partially within the housing. A cutting edge of the blade element is selectively exposed for making an incision in a patient. The blade element is disposed at one end of the housing and the hook element may be disposed at an opposite end of the housing. The blade element may be selectively exposed via actuation of a first user input that imparts a movement of the blade element relative to the housing and towards an extended position where the cutting edge of the blade element is exposed. The blade element may be biased toward the extended position via a biasing element, which may urge the blade element toward the extended position responsive to actuation of the first user input.

19. A vein removal device, comprising:
-
a housing longitudinally extending from a first end portion to a second end portion; a blade element, including a cutting edge, disposed at least partially within the first end portion of the housing; a hook element disposed at the second end portion of the housing; a first user input device, operably coupled to the blade element and positioned closer to the first end portion of the housing than the second end portion of the housing, actuatable from a resting position toward a depressed position along substantially perpendicular direction relative to the extension of the housing, wherein actuation of the first user input device from the resting position toward the depressed position causes the blade element to move relative to the housing from a retracted portion within the first end portion to an extension position in which the cutting edge is exposed; and a single biasing element positioned and configured to bias the blade element toward the retracted position. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
